OLED lighting, growing their presence

By HyunJun JANG (hyunjun@ubiresearch.com)

 

As the OLED lighting has expanded its applications, the expectation is raised for the beginning of the OLED lighting market. In particular, LG Display has recently completed the OLED lighting production line and started attracting customers.  As a result, there is much attention towards the growing OLED lighting market.

 

LG Display is said to supply its OLED lighting to Baskin Robbins Brown store in Cheongdam Dong and the ‘transparent connection solution’ applied OLED lighting to IOPE store in Myeong Dong.  The company explains as the thickness of lighting is as thin as 0.88mm, it enhances aesthetic effect, and does not effect on cosmetics and other displays with less heat generated.

<OLED lighting applied to IOPE store, Source: lgoledlight.com>

Until recently, compared to OLED display for mobile devices and TVs, OLED lighting has shown slow growth.  However, OLED lighting is thinner, lighter, and more flexible so that it is now being consideres as a next generation lighting.  By tapping on the strengths, it has applied not only to indoor lighting but to cars, exhibitions, and many other industries.

More recently, IKEA announced to release a new lighting product of Vitsand with 7 OLED panels while Mercedez-Benz decided to apply OLED lighting for taillights of both 2018 Benz S class Coupe and Cabriolet.

According to the 2017 OLED Lighting Annual Report published by UBI Research, the global OLED lighting panel market is expected to grow rapidly from 2020, becoming $1.9 billion worth of market by 2021.

Fraunhofer Institute will introduce automotive flexible OLED lighting at ISAL 2017

Specialized in development and manufacturing OLED module, Fraunhofer Institute will introduce Automotive flexible OLED lighting with adjusted color at ISAL 2017 which will be held in Darmstadt, Germany from 25th to 27th September. Fraunhofer Institute had released previously OLED which the color can be adjusted by rigid substrate in 2015.

Fraunhofer Institute has continued to develop flexible OLED lighting since then. Flexible OLED lighting which will be shown at ISAL 2017 is known to be changed to yellow and blue color. It can be shown as white light by making of yellow and blue color at the same time.

Fraunhofer Institute predicts that flexible OLED lighting will be replaced for car interior lights and it could also be used on the ceiling or winding parts where lights cannot be built easily. Commercial lighting is required to have heatsink and unfortunately it can not be easily built with lack of flexibility in design. However flexible OLED lighting is very light and thin which means it is expected to be widely used for Automotives interior with its flexible design. Fraunhofer Institute also made a comment that they may produce flexible OLED substrate glass, metal and plastic film as well.

OLED lighting has been recently used for Automotives interior and it is expected to be used more in the next generation. Customized Automotive service company, Changscustom showed OLED lighting built in the car at Seoul Auto 2016. Furthermore lighting companies including LG Display and Osram supplied OLED tail light with Mercedes-Benz and BMW.

Meanwhile, according to 2017 OLED Lighting Annual Report which was recently published by UBi Research, using of Automotive OLED Lighting will be increased to $2.11 billion in 2025 from $6.4 million in 2017 with 107% of growth rate. Especially flexible OLED Lighting is expected to capture a higher market share more than 95% and flexible OLED Lighting will be widely used instead of rigid OLED lighting.

Starting to have mass production process in Gen5 OLED of LG Display from end of September, lighting market is expected to reach full growth. The growth of OLED lighting market is being watched with keen interest to compare with strong growth of OLED display market.

UBI research publishes 2017 OLED lighting report : LG Display, ready to mass-produce OLED light panel, expecting OLED lighting market to grow fast

■ LG Display starts mass production of 5G OLED panel for lighting from the end of September

■ OLED lighting panel market is projected to grow from US$ 1.9billion in 2021 to US$ 5.8billion by 2025

 

LG Display will start mass production of 5G OLED light panels from the end of September, therefore attention is focused on whether the OLED lighting market is growing rapidly. According to LG Display, monthly production capacity is 15K, and it is to be increased to 90K later.

 

According to the ‘2017 OLED Lighting Annual Report’ published by UBI Research on August 8, the global OLED lighting panel market is expected to grow to about US$ 1.9 billion by 2021. Furthermore, it is projected to have a CAGR of 85% for the period 2017-2025, and form a market of US$ 5.8 billion in 2025.

Because OLED lighting is thin, light and flexible, it does not limit the installation space and has excellent design autonomy. In addition, OLED lighting is used for automotive, exhibition, and medical as well as general indoor lighting because it can create a comfortable atmosphere with little heat and flicker.

 

However, the market for OLED lighting has been slower than that of OLED display, which is widely applied to mobile devices and TVs. Osram focuses primarily on automotive OLED lighting, and Philips sold its OLED lighting division to OLEDWorks. Also, Japanese panel makers such as Sumitomo Chemical and Konica Minolta have developed OLED lighting for industrial and medical applications. Nevertheless, it seems to take time for OLED lighting to become eventually a large market.

With LG Display’s mass production of Gen5 OLED line, the price of OLED light panel is estimated to drop below US $ 10 (100 x 100 mm). The significant price competiveness might enable OLED panels to be applied to various areas such as automobile and display lighting as well as indoor lighting. Owing to this expectation, attention is focused on whether the OLED lighting market, showing signs of slow growth, can be materialized.

UBI Research predicted that LG Display would account for about 70% of the world’s lighting OLED panel market in 2017, and will continue to lead the OLED lighting panel market with a 50% market share in 2020.

 

Meanwhile, ‘2017 OLED Lighting Annual Report’ describes trends of next-generation lighting market, promising applications, cost analysis upon the investment of LG Display and forecast of OLED lighting market. Since it analyses particularly OLED lighting market, materials market, and equipment market forecasts for OLED lighting from various perspectives, it is expected to help the related companies identify the OLED lighting market.

The OLED is the best automotive display

The seminar on the trend of the up-to-date technology for the next generation display which was themed ‘The technology trend for latest display and the automotive display’ hosted by the UBI Research, was held on July 14th at COEX in Seoul.

 

 

In the seminar, Sun-hong, Park, a senior researcher of automotive parts, said that “The attention to the display is increasing due to the importance of the visual intelligence, and its application will also grow because the OLED is able to easily realize the flexible deign and the transparent display.”

In addition, he expected that “The digitalization for the automotive will be lasting, and the China will take 50% and more of the worldwide consumption market for automotive in 2020, and the application of display including OLED will increase in accordance with the attributes of the Chinese who prefer colorful design.”

During the briefing of a car not having a side mirror which became an issue in recent, “The application of the OLED which has rapid response speed and wide viewing angle is highly likely to be employed. If it can just overcome the reliability, the OLED will be the best display for the automotive.”

In the other side, according to the “Automotive Display Report – application & market trend analysis and the market forecast” published by the UBI Research, it expected the OLED panel will be started in earnest applying to the cluster or CID of the automotive from 2018, and the automotive display is expected to grow about 17% annually, reaching around US$ 25,000 million by 2022. The AMOLED panel market among this will be account for about 20%.

Softly bending OLED lighting like a paper, Development of Roll-to-Roll manufacturing technology

<Shin Kwon, Senior researcher of Korea Institute of Machinery and Materials (KIMM) & OLED production Roll-to-Roll production equipment, source: KIMM>

Korea Institute of Machinery and Materials (KIMM hereafter, Cheon-Hong Park, the president of KIMM), the Ministry of Science, ICT and Future Planning-affiliated developed the 300mm grade of Roll-to-Roll manufacturing technology that allows to produce flexible OLED* by simple process with GJM Co., Ltd (Mun-Yong Lee, CEO) for the first time in Korea.

 

The Printed electronics research laboratory of advanced production equipment research center in KIMM succeeded in applying traditional Roll-to-Roll printed electronics technology to the OLED production process. Using Roll-to-Roll vacuum evaporation equipment, it is possible to produce flexible OLED products inside a single chamber as evaporating OLED light emitting organic layer and metallic electrode to roll type film in order. Available OLED products consist of many organic, inorganic layers of 1~hundreds nanometer (nm) level of thin and each layers are manufactured through vacuum thermal evaporation process.

 

Producing the flexible OLED display must go through complicated processes until now. The method that has been used so far is that attaching a film on the glass plate and passing it over the evaporation process to produce OLED, and then separating a film from the plate. The one-side curved display of smart phone screen which was launched by Korea conglomerate was made in the same manner of process which is attaching a film on a glass plate or coating and then circulating evaporation equipment to produce OLED and separating OLED from the glass plate. There were demerits of the need for adding additional process of attaching and detaching a film as well as for various additional evaporation equipment upon necessary steps.

 

Applying the currently developed technology, it is possible to produce OLED with ‘multi-layer evaporation’ process that evaporates organic layer and inorganic layer sequentially on top of a film after letting a roll type film which is rolled inside a vacuum chamber flow. The time and facilities required for production are greatly reduced, therefore, not only large companies but also small and medium-sized enterprises can produce flexible OLED.

 

This OLED producing method is expected to be used in the lighting industry first since it can be produced by surface unit unlike point unit of the existing LED, and be possibly made in any desired shape due to its flexibility.

 

Shin Kwon, senior researcher of KIMM explained “With Roll-to-Roll vacuum evaporation equipment, it can be used for continuous production of flexible OLED which is notable display for the next generation. Especially in the display industry, it is a key technology to secure the technology gap feasible to contribute to gain supremacy over China from its rapid pursuit while Korean R&D is stagnant.

 

Also added “we are under development of fine pattern mask align technology which allows to produce individual pixels Red/Green/Blue used in actual display product. When it’s completed, it can be applied to the high resolution display and is a strong technology differentiated from Fraunhofer in Germany and Konica Minolta in Japan developing similar technologies.

 

This task was conducted for the leading study sponsored by the ACE*** program which is a technical business support program of KIMM, and has been conducting with GJM Co., Ltd. with a support of the economic cooperation business of the Ministry of Trade, Industry and Energy since Oct. 2015. GJM Co., Ltd. as a hidden champion holding core technology in OLED, recently made a delivery performance in Taiwan, Japan, and China and is pushing ahead with full-scale equipment commercialization.

OLED enabling various styling and designs is perfect to lighting for automobiles

Applications of various lighting such as LED and OLED etc. have been expanded so as to implement unique designs and diversified functions of own brand by each automotive company as well as developments of automotive industry including smart-car and connected-car etc. are being made at the same time. In this regard, Center Head Ju Jae-young of Korea Photonics Technology Institute stated current situation by saying “Lighting for vehicles belongs to the business which expects profitability, but it is not easy for late starters to break in because entry barrier is high from characteristics of automotive industry. Ultimately, whether to stimulate purchase desires is important.” Also, he counted ‘styling possibilities’ as one of successful LED lighting by saying “The reason of getting more popularity of LED than existing halogen and HID is derived from the fact that LED has strong points in designs.”

And then, the Head forecasted like “The exterior deco of lamp market for automobiles overtook the interior deco market from the start of 2013, and 3.1B USB market will be made in 2019 by achieving annual 11.6% growth in average to 2019 from 2014,” and said “The exterior deco market will grow up over 15% annually, and DRL (Daytime Running Lamp) and Head lamp are leading market due to their high growth rates.”

Besides, Center Head Ju Jae-young stated “In order to enter market by OLED, it has to stimulate purchase desires with new designs which do not substitute LED simply,” and added “There are possibilities if designs are unique, and stimulate sensitivity like Fun- VII concept car of Toyota or lighting of Chrysler having been disclosed to the public in 2013.”

LG’s OLED light experience began in 2000 with R&D into OLED materials at the Group’s chemicals affiliate, LG Chem, with production of OLED light panels beginning in 2012.

The acquisition last year of the OLED light panel manufacturing business by LG Display has been creating synergies with its production infrastructure and technology in OLED displays.

It allows the company to save costs through integrated purchasing and shared investments, increase productivity by drawing on the accumulated knowledge of the display business, and help improve production infrastructure and use of technology patents.

OLED light is made up of layers of organic materials which is self-illuminating and consumes less power and also emits lower heat than conventional lighting.

It is environmentally friendly and is closest to natural light. Due to its ability to be thin and flexible, it is suitable for different applications and venues and could create new markets for lighting.

According to UBI Research, a market research firm, the OLED light market is expected to grow rapidly from US$ 135 million in 2016 to US$ 1.6 billion in 2020.

OLED and Graphene Together Achieves Innovative Technology

By Choong Hoon Yi

 

Korean research team is expected to greatly improve display’s transmittance and picture quality through fusing graphene technology, focus of much attention as the new material to OLED technology.

 

On December 15, ETRI (Electronics and Telecommunications Research Institute) replaced the thin metal electrode that was used as transparent electrode on top of the OLED substrate with graphene transparent electrode, and succeeded in developing original technology that is conductive and transparent.

 

This research results were presented in Scientific Reports, a journal from the publishers of Nature on December 2.

 

The metal electrode used in OLED until now has been mostly silver material, but due to the reflection of internal light, the viewing angle changed depending on the angle. The external light also affected picture quality due to reflection.

 

In order to solve this problem, ETRI research team focused on graphene that mostly does not reflect internal/external light. By replacing the material, the team reported that the transmittance increased by approximately 40% and reflectance improved by approximately 60%.

 

OLED was successfully lighted by attaching graphene transparent electrode to the organic layer on top of the film form (23 x 23 mm, 30 ㎛ thickness) of substrate. The research team believes this will be able to contribute much when applied to transparent OLED display and white OLED-based large area OLED display in future.

 

Particularly, unlike the existing vacuum process OLED production method, this technology can be employed via lamination where film is attached to the organic layer and graphene. Therefore, OLED can be produced through simpler process. It is expected that this can be evolved into production technology using roll to roll process.

 

Additionally, ETRI, together with Hanwha Techwin, is working on applying graphene transparent electrode to OLED’s lower electrode through collaboration of high quality graphene thin film electrode materials. The related technology development results were published online by The IEEE (Institute of Electrical and Electronics Engineers) of Selected Topics in Quantum Electronics.

 

ETRI’s Dr. Jeong-Ik Lee (soft I/O interface research section) anticipated that “this technology will be able to play a role in widening the gap with latecomer countries in OLED industry where challenging latecomers are strong”.

 

This research was carried out through Korea’s Ministry of Science, ICT and Future Planning and Institute for Information & Communications Technology Promotion (IITP)’s “Energy reducing environment adapting I/O platform technology development for future advertisement service” project and Ministry of Trade, Industry and Energy and Korea Evaluation Institute of Industrial Technology’s “Substrate size 5.5 generation or larger graphene film and OLED device/panel foundation and application technology development for graphene materials OLED transparent electrode and thin film encapsulation application”.

 

ETRI is planning to additionally develop sheet tension reducing technology by manufacturing metal in thin, grid forms and enlargement technology to produce mobile display size within 2016.

 

Through this technology, the research team produced 6 international patent applications and 6 papers. ETRI is intending to transfer the technology to graphene film and display panel companies among others. Commercialization is estimated to begin after 3 years.

In this exhibition, ETRI presented OLED lighting that used graphene as the electrode. ETRI’s Dr. Jeong-Ik Lee explained that recently interest in graphene electrode is increasing to replace ITO electrode and to apply graphene electrode, optical, electrical, and process issues have to be considered. When graphene is used as OLED electrode instead of ITO, thickness and refractive index change optically and electrically energy levels change, and these have to be considered when designing. He also emphasized that in terms of process, it has to be designed keeping in mind of before and after process of electrode procedure. Dr. Lee revealed that at present optical and electrical issues are solved while the process issues are in research stage, and they are planning to present the results of this research within this year.

 

Graphene, with its high resistivity, is known as next generation electrode material favorable to flexible and foldable. Dr. Lee pointed out that graphene has wider viewing angle than ITO when used as transparent electrode is another important advantage, and particularly as white light source’s spectrum cannot change according to the viewing angle, graphene is suitable for application.

 

Graphene is a key material with a wide arrange of applications, it is being developed in diverse areas such as OLED encapsulation as well as in electrode sector. The Ministry of Science, ICT and Future Planning of Korea estimated that domestic graphene market will record 19 billion KRW until 2025. Korea Evaluation Institute of Industrial Technology, the organization in charge of this national project, gave their target as developing 9 top technology through graphene and achieve 17 billion KRW sales. Regarding this, Dr. Lee emphasized compared to other countries, Korean investment in graphene is relatively low and that now is the time for the Korean corporations and government agencies to pay more attention higher value-added businesses.

[Expert Talk] OLEDWorks’ Co-founder David DeJoy Talks New Lighting Experience

Through an interview with OLEDNET and his presentation during the OLEDs World Summit (October 27-29), OLEDWorks’ co-founder, chairman and CEO David DeJoy discussed OLEDWorks’ vision and OLED lighting.

 

OLEDWorks hit the headlines in April this year when it was announced they would acquire key OLED assets and relevant intellectual property from Royal Philips whose main OLED product is Lumiblade. This acquisition was finalized earlier this month, taking this relatively small but already dynamic player within the OLED lighting industry to another level with plans that include continuing production in both Germany and the US, and expanding the product portfolio.

 

As the world’s first area light source, OLED lighting is naturally diffusive. As the light is uniform without flickers, the glare and eye fatigue is minimized. Although it is similar to LED in that it is a solid-state lighting, OLED produces little heat and color temperature can be easily adjusted. With its thinness of the panel and no need for extra installation space, OLED lighting can bring forth new design perspectives and applications. During his talk, DeJoy commented that OLED will bring the light closer to the user and will deliver a better light experience in diverse settings including patient rooms, recovery rooms in hospitals, retail, and museums.

 

Although customer response to OLED light quality is extremely positive, DeJoy acknowledged that it is facing many challenges in entering the lighting market and divided the strategy to overcome this into “the four ‘A’s”: awareness, adaptability, availability, and affordability.

 

The ‘awareness’ includes education about the technology and benefits, as well as confidence in the OLED lighting technology reliability. The effort to build the OLED lighting awareness includes government partnerships such as DOE Funded Gateway Projects, and NYSERDA Demonstration Projects. Designers and architects are also increasingly turning to OLED for inspiration and source material. OLED lighting’s previously mentioned advantages are closely linked to the second ‘A’, ‘adaptability’. Its thinness, lack of heat, and no need for additional installation space mean that OLED lighting can easily be integrated into fixtures and used as a building material by being directly mounted on surfaces. On the subject of ‘availability’, DeJoy emphasized that more luminaire and final products should become more available to specifiers. He added that there are many in product development but they need to get into the hands of the end user. Discussing the ‘affordability’ of OLED lighting, DeJoy used OLED panel cost scenario published by the US Department of Energy which estimates that the panel price will continue to fall to reach US$10/klm, which corresponds to approximately US$100/m2, in 2025. DeJoy added that when examining the affordability of OLED lighting, the total cost has to be considered. For example, OLED lighting does not require heat sink or extra installation cost. Also, many applications do not need very high lumen output with focused beams; “it is not all about $/klm”.

DeJoy explained that OLEDWorks long term goal is making OLED lighting adaptable and available, making it easier to change the lighting when it is broken, and be user friendly. He reported that OLEDWorks will continue to expand the product portfolio, which now includes Lumiblade, for “increased performance, additional form factors, and additional CCT options, while reducing product costs”. DeJoy also added that this is “akin to the LED evolution and consistent with the U.S. Department of Energy forecast”. With their proactive and enthusiastic approach to the OLED lighting market, the industry is watching OLEDWorks with great interest. OLEDWorks’ effect on OLED lighting market is expected to be significant.

LG Chem.’s OLED Lighting Business Toward LGD. What is the Future Direction?

It was announced that LG Display will take over LG Chem.’s OLED lighting business department. As the department that was leading the opening of OLED lighting panel market is being merged into LG Display, a significant change in OLED lighting industry is anticipated.

 

One of the merits of this merge is expected to be further improving OLED lighting panel’s mass production potential through LG Display’s existing OLED panel mass production line, labor, and technology. Additionally, when new investment of OLED lighting panel mass production line is being processed, time and cost can be reduced on the basis of LG Display’s manufacturing equipment/material supply chains.

 

On the other hand, as OLED lighting market is still in initial stages the size is not so large. As such, whether LG Display will newly invest is a key issue. Generally, for display panel companies that invest with market size of thousands of millions of dollars in mind, OLED lighting panel line’s new investment does not seem to have a great advantage for LG Display.

 

Therefore, if LG Display carries out OLED lighting panel business, the first step is estimated to be mass production in parts of Paju’s AP2 line rather than new investment for OLED lighting panel mass production line. If parts of AP2 line begin mass production first, mass production timing can be much sooner than new investment and can positively affect expansion of OLED lighting panel market.

 

The issue is marketing strategy. In 2009, Samsung Electronics successfully opened AMOLED smartphone market in Korea via push strategy using AMOLED themed music video that became viral. Much like this, in order to show profit in OLED lighting panel business, LG Display should open the market through push marketing strategy.

[IAA 2015] Audi and Porsche, Propose Future Models of Smart Car

At IAA 2015 (September 17 – 27), Audi and Porsche presented OLED lighting and display equipped vehicles.

 

In the past, Audi has proved OLED technology’s excellence through diverse models and demonstrations, including introduction of ‘swarm’ in 2013 with its 3D OLED car rear lighting panels. At this motor show, Audi revealed Audi e-tron quattro, the first concept car with Matrix OLED technology. As well as the Matrix OLED lighting, interior OLED display was also applied to the concept car. Audi explained that the Matrix OLED lighting, which was applied to the rear lighting, can continuously change lights and does not cast shadow. Full OLED interface was also applied to the car and all functions required in driving can be control by display touch. Audi revealed that they will gradually apply these technology to next generation Audi series.

 

Porsche presented their first four-seat electric sports car Mission E as a concept model. The instrument cluster for this concept car is displayed virtually in OLED. The menu can be activated through buttons on the handle. It can also be automatically activated as the cluster’s eye tracking system can perceive the driver’s attention. The display also follows the seat position and body attitude of the driver in what is known as a parallax effect; the display moves according to the driver’s posture for easier viewing. Porsche revealed that Porsche Car Connect technology will also be applied which will allow the user to control key functions of the vehicle through a smartphone.

 

As OLED using lighting and display are actively applied to smart cars, attention on the automotive OLED is also increasing. At the National Research Development Industry General Workshop, held in July 2015, Samsung Display and LG Display each stated their thoughts on display that will be applied to future smart cars.

 

Samsung Display’s executive director Hye Yong Chu asserted that smart is display’s future, including smart car. She also explained that for the actualization of smart technology, other ancillary smart technology, such as eye tracking and voice recognition technology, are required.

 

Yoon Sooyoung, LG Display’s vice president, stated that automotive display can be used for CID, dashboard, cluster, and window, and that the development of transparent and flexible technology is necessary.

 

During the keynote session of IMID 2015, Munhyun Kim of Hyundai Motors revealed that OLED panels will mainly be applied to smart car compared to LCD as it can easily be flexible. He also added that the automotive OLED’s percentage within the total OLED market will increase, and anticipated that it will exceed 30% in 2017.

Mitsubishi Chemical and Pioneer Develops Bluelight-less OLED Lighting

Japan’s Mitsubishi Chemical and Pioneer announced their success in developing the first bluelight-less OLED lighting module. The two companies produced this module through a wet coating process for the light-emitting layer and began shipping samples on August 1.

The new OLED lighting module does not use blue emitting materials in the OLED panel and the light from the panel contains a minimal portion of blue light. According to the companies, this is less than 1% of the amount in the 3000K-type OLED lighting module developed by Mitsubishi Chemical and Pioneer.

The panel is a candle-color type with a 1900K color temperature; this is suitable for storage lighting of light-sensitive items such as cultural heritage and paintings, as well as lighting for bedrooms and medical practices.

Blue light, which has a wavelength of between 380 and 495 nanometers, has the highest energy among visible light. This is enough to reach the retina at almost full strength. This can cause eye fatigue as well as reduction in quality sleep.

With the increase of smartphone and PC use, the amount of time exposed to blue light is also increasing. Therefore, as the interest in eye health rises, this bluelight-less OLED lighting module development is worthy of attention.

Recent smartphone trend is moving from high resolution and specs toward diverse designs such as curved or bendable/foldable and flexible display that can differentiate applications. AMOLED flexible display is currently being applied to smartphone and smartwatch. However, only 2 companies, Samsung Display and LG Display, are supplying these high spec flexible AMOLED panel.

 

Small and medium-sized panel companies do not have the technology to mass produce high performance flexible AMOLED panel and cannot invest in mass production. For these reasons, Chinese and Taiwanese small and medium-sized companies are aiming for finding new applications where flexible PMOLED or low resolution flexible AMOLED can be applied and make mass production investment. Accordingly, set companies’ interest in flexible OLED applied application is also increasing.

 

Additionally, companies are in agreement that yield of flexible PMOLED that is applied to some smartbands does not meet demand. Taiwan’s wisechip and RiTdisplay, key PMOLED companies, are concentrating on developing flexible PMOLED and flexible OLED lighting. Taiwan’s AUO and Innolux, and China’s Visionox and EDO are also among those that are developing wearable flexible AMOLED.

 

Diverse application development where lower resolution flexible AMOLED, flexible PMOLED, or flexible OLED lighting, instead of expensive high-end smartphone and smartwatch, can be applied is essential. The outcome of this is forecast to greatly affect the growth of small and medium-sized OLED panel companies.

New Solution for Next Generation OLED Lighting

Professor Lee Taek Seung of Chungnam National University

Professor Lee Taek Seung of Chungnam National University

 

Professor Taek Seung Lee and Jongho Kim (Chungnam National University’s Department of Advanced Organic Materials and Textile System Engineering), and Professor Jin Sung-Ho and Park Juhyeon (Pusan National University’s Graduate Department of Chemical Materials, and Institute for Plastic Information and Energy Materials) authored a paper titled ‘Synthesis of conjugated, hyperbranched copolymers for tunable multicolor emissions in light-emitting diodes’. For 2015 June issue, Polymer Chemistry, published by the Royal Society of Chemistry, selected it as its back cover.

 

The paper discusses research of polymer material applied to solution process and explains that through polymer structure in the form of hyperbranched red, green, and blue monomers, diverse colors, including white, can be actualized depending on the amount of each monomer. Existing OLED lighting used R/G/B or YG/B stacking structure to produce white OLED, complicating the process. Although a method of producing white by combining R/G/B together is being developed, energy displacement between R/G/B can cause unwanted colors. However, if the R/G/B monomers can be introduced to polymer structure as hyperbranched forms as the paper suggests, the energy displacement can be minimized when the polymer solidifies which makes it easier for the colors to be realized.

 

Professor Lee revealed that hyperbranched polymer materials were used in the research and that as white can be produced from just one polymer material, simple process can be used for the production.

 

The patent for this technology has been applied (application number 10-2012-0091350) in Korea. It is anticipated that this will become a key technology for reducing the next generation OLED lighting production cost.

[Expert Talk] Professor Ho Kyoon Chung of Sungkyunkwan University, Talks OLED Lighting’s Future

Professor Ho Kyoon Chung, a chair professor of Sungkyunkwan University who previously held a position of head of Samsung Display research lab, developed products at the OLED display development forefront while in the industry. He is a world renowned OLED expert who is, at present, concentrating on flexible OLED lighting development at university.

 

Professor Chung is developing flexible OLED lighting together with Korean material companies, lighting company, and Germany’s Fraunhofer Society. Chung is pursuing development of flexible OLED lighting that can produce white light via CCL (color change layer) made with fluorescence and QD materials on top of R2R evaporator produced blue emitting material on stainless steel substrate.

 

Chung considered the automotive flexible OLED lighting application to be the most important factor in flexible OLED lighting’s success. Most of the companies that are currently developing OLED lighting use multi stack structure as they are aiming for high efficiency device to compete against LED.

 

However, Chung pointed out the condition required for OLED lighting to enter the market is production cost rather than efficiency.

 

Chung emphasized that reducing the OLED lighting production cost is a priority and explained that many lighting companies that he has met wanted lower priced panels as OLED lighting is not used in everyday life even with high OLED lighting efficiency. Chung mentioned that in order to achieve this OLED structure needs to be simple more than anything. The OLED structure that Chung is developing is the simplest structure that uses only the blue layer. Therefore if the development is successful the production and investment cost can be massively reduced.

 

What is Professor Chung’s flexible OLED lighting growth solution?

 

The rear lamp and interior lights of automotive that current vehicle makers are pursuing use batteries, and does not require high efficacy products unlike other lightings. For these reasons, Chung explained that automotive lighting is the best market where OLED lighting with simple structure can be applied, and forecast the best product that can place the lighting following the curved design is flexible OLED lighting.

 

On the other hand, Chung revealed that there are some difficulty in technology before flexible OLED lighting can be commercialized and form a market worth billions of USD. Blue emitting material was named as the most necessary part, an analysis that material’s color purity and efficiency are not quite enough for the blue material to produce white light. The second is encapsulation technology and materials. Chung indicated that the important aspect in attaching the gas barrier to the device is high moisture proof adhesive material and passivation technology. He also stated that speedy equipment is required.

 

Professor Chung concluded that flexible OLED lighting is certain to represent Korean IT industry following display industry, affirming his passion to continue in his effort in making sure flexible OLED lighting grows into an axis of OLED industry. He did not forget to add an entreaty for the materials and equipment companies to press on in their development.

 

 

OLED Rises to Become Purple Ocean of Existing Lighting Industry

OLED is receiving much attention as the next generation lighting as a greener lighting that can replace existing incandescent and fluorescent lights and reduce energy consumption, as well as lighting that can create new market. According to this trend, many organizations are analyzing OLED lighting industry in diverse directions and presenting the analysis.

At the 5th LED Industrial Forum which was held recently together with LED & OLED Expo 2015, Song Hyokyung, a senior researcher of WIPS, gave a presentation on the topic of OLED lighting industry’s patent trend and market status. She explained that as OLED lighting sector is a new market with a great growth potential, the technology development competition is fierce, and presented SWOT analysis results of Korean businesses.

For Korean OLED lighting industry’s strengths, Song gave examples which included world’s highest quality of OLED, AMOLED development and mass production technology, production ability, and diverse convergence technology solution. As for the opportunity factors, Song suggested application expansion through convergence with flexible technology, and increase in demand as the lighting market expands. On the other hand, Song revealed that the deficiency in original key technology on OLED material and components and the lack of mid to long term strategy regarding new technology development could be a weakness for Korean industry. She also gave China’s pursuit, possession of intellectual property rights by leading companies, and appearance of new light sources such as QLED (quantum dot emitting diode) as factors that could pose threat. However, OLED lighting induces warm atmosphere as well as being environmentally friendly and a future convergence industry. With these factors, Song concluded that if these weaknesses and threat factors can be overcome, OLED lighting will be able to show higher CAGR than other lighting markets.

UBI Research analyzed OLED lighting industry via STEEP analysis method in OLED Lighting Annual Report, published in May, 2015. UBI Research analyzed that as income increases, interest in interior design light using specialized lighting, other than necessary lighting, increases. Also, in terms of technology, OLED lighting projects in Korea, the US, and Europe are actively being carried out and estimated that the technology development will gain speed through related technology integration.

Economically, UBI Research analyzed that the market entry barrier is not high as the OLED lighting industry is not monopolistic. In terms of environment, incandescent lighting’s carbon production and fluorescent light’s mercury are becoming big concerns. Based on these factors UBI Research forecast that demand for green lighting, such as OLED lighting, will increase. Policy wise, OLED lighting industry clusters were formed and are supported by Korean and Japanese governments. As OLED lighting related projects are also being vigorously carried out OLED lighting industry is expected to become a high growth industry.

Based on both analyses OLED lighting is anticipated to be an industry with much potential for growth. If speedy technology development occurs and demand for environmentally friendly lighting increases, it is expected that the OLED lighting share of total lighting market will rapidly increase. UBI Research estimated that total OLED lighting market will grow at CAGR of approx. 70% from 2016, and show US$ 10,000 million revenue in 2025.

[LED/OLED EXPO 2015] Low Cost OLED Lighting Panel Production, QD Film Provides the Solution?

One of the reasons that OLED lighting is not becoming commercialized, despite its diverse advantages compared to other lightings, is its high price. The most fundamental way to reduce OLED lighting panel cost is investment in OLED lighting panel mass production line. Price reduction for components and materials is also an important factor.

 

The OLED lighting panel that is currently being mass produced has red/green/blue or yellow/blue stack structure. Also the use of tandem structure of more than 2 stacks to increase efficiency makes the process complex, lowers the yield, and increases the amount of materials used, and is becoming a key factor in increasing the production cost.

 

At LED/OLED Expo 2015, Cheorwon Plasma Research Institute (CPRI) displayed technology that produces white by applying light extracting film that contains red and green quantum dot (QD) material on blue OLED. CPRI forecasts that this technology of QD film applied blue OLED will be the solution for lowering OLED lighting panel production cost.

 

CPRI’s senior researcher Yong Hwan Yoo explained, “When QD light extracting film is applied to blue OLED, the evaporation processes are reduced compared to existing RGB or YB tandem structure OLED lighting. This could lead to production cost reduction as the yield increases and material cost decreases. If the QD purity improves, as well as blue material’s lifetime and efficiency, it is anticipated that the efficacy will match that of RGB or YB tandem OLED lighting panel.”

 

CPRI exhibited LED caps to be used for mascots at the opening/closing ceremonies of PyeongChang 2018 Winter Olympics, ultimately aiming for manufacturing them using OLED lighting panel instead of LED.

 

 

[LED/OLED EXPO 2015] O’CLESS Propels OLED Lighting Commercialization

At LED/OLED EXPO 2015 (23 – 26 June), HaeChan Design revealed that through OLED lighting specializing brand O’CLESS they are expanding into international market as well as within the domestic market in Korea.

 

HaeChan Design was established in July, 2013, and launched OLED lighting brand O’CLESS. O’CLESS is producing using the combination of LG Chem.’s OLED lighting panel, and their own designs and ideas.

 

In this exhibition, O’CLESS presented diverse lighting such as night light, portable light, stand light, mirror light, and rail connection down light. Particularly, smart system that can control down light using smartphone drew much attention from the visitors.

 

Seungchul Oh, the President of HaeChan Design, reported that they “began exporting to Japan and China following the domestic release in Korea”, and they are planning to “expand the market as a global OLED lighting specializing business once the new business establishment in Innovation City Chungbuk is completed”. Regarding the price issue, which is OLED lighting market’s biggest obstacle, Oh viewed future of OLED lighting market in a positive light: “P company’s night light is being sold for 200,000-300,000 KRW (200-300 USD) but even with application of OLED and Retinispora wood, O’CLESS’ product has competitive edge with approx. 100,000 KRW (100 USD). Although panel’s price is essential as design and practicality are more important in the lighting industry, application creation appropriate for the high cost of OLED is more important. OLED panel price has already fell considerably and will continue to do so and therefore can compete against LED or other lightings in terms of price.”

 

In February this year, HaeChan Design installed approximately 1,000 OLED desk lamps with LG Chem.’s OLED lighting panels in Seoul National University’s library. They also set up booths in 2014 LED/OLED Application & Technology Show and 2015 Kyunghyang Housing Fair, focusing on O’CLESS marketing.

Seoul National University’s Research Team Lead by Professor Changhee Lee Succeed in Developing High Output QLED Emitting True Ultraviolet Light

South Korean research team lead by Professor Changhee Lee in Seoul University succeeded in making first quantum dots that emit ultraviolet light and used them to produce a flexible, light-emitting diode.

UV light is usually produced by mercury lamps or LEDs made from inorganic materials such as gallium nitride (GaN). However, mercury lamps tend to emit a wide range of visible wavelengths as well as UV, and high-performance gallium nitride LEDs are expensive to make. According to Professor Lee, quantum dots are an attractive alternative which can be made using potentially less expensive solution-based processes.

Quantum dots, made out of a semiconductor material, emits different wavelengths depending on the size and shapes. The smaller the crystal, the shorter the wavelength of the light it emits. The Professor Lee’s team is the first in succeeding in making quantum dots that emit wavelengths shorter than about 400 nm, the high end of the UV spectrum.

In order to produce UV nanocrystals, the team had to figure out how to make quantum dots with light-emitting cores smaller than 3 nm in diameter. To make these, the team utilized cadmium zinc sulfide, which emits high-frequency light, zinc sulfide shell. The quantum dots produced through this method emit true UV radiation at about 377 nm. Professor Lee explained that they “can go to much shorter wavelengths than people generally expected from quantum dots”.

The research group then made a flexible LED with the quantum dots, using a design for a high-efficiency device they developed in 2012. Professor Lee’s team showed that the UV LED could illuminate an anticounterfeiting mark in a bill of paper currency. Franky So, a materials scientist at the University of Florida, says making a device out of the quantum dots that shines brightly enough to reveal the currency mark is a remarkable accomplishment. If their lifetimes can be improved, these potentially low-cost UV LEDs could find uses in counterfeit currency detection, water sterilization, and industrial applications.

The research team headed by Professor Lee includes Seoul National University, Professor Seonghoon Lee and Professor Koonheon Char, and Dong-a University’s Professor Jeonghun Kwak. The research was published in Nano Letters (Nano Lett. 2015, DOI: 10.1021/acs.nanolett.5b00392), a monthly peer-reviewed scientific journal, and reported on Chemistry & Engineering (27 May), published by the American Chemical Society.11

Lighting Industry Market Control by Stable Major Companies, OLED Lighting Shakes It Up

Key companies of lighting industry, such as Osram, Philips, Panasonic, and GE Lighting, occupies approximately 70% of total lighting market and maintains stable entry barrier. Most of the key companies are also actively carrying out OLED lighting development as next generation lighting. As they reveal new OLED lighting panels each year, it is estimated that these companies will play a major role in next generation lighting market.

However, once OLED lighting market is vitalized, the existing lighting companies’ stable market control is expected to be rattled.

OLED Lighting Annual Report, published by UBI Research, pointed out that major lighting companies have already invested in LED lighting in large scale, and estimated until the investment cost is returned new investment for OLED lighting will be difficult. To stimulate OLED lighting market the report suggested push market, a strategy being used in display market. According to the report, the production cost competitiveness can be achieved through aggressive investment by LG Chem. and new OLED lighting companies such as Lumiotec. The report also estimated once OLED lighting market is open through aggressive investment and push market strategy, the lighting market leadership will be transferred to new OLED lighting companies which invested in OLED lighting early from major companies which missed investment timing.

100x100mm OLED Lighting Panel Production Cost, US$ 2.5 Also Possible

As environmental issues are becoming a global concern, countries around the world are introducing environmental policies. Lighting occupies approximately 1,900,000,000 tonnes of global annual carbon dioxide emissions, and is becoming a big environmental regulation issue. Also as it takes up 25% of global power consumption it is an important area for energy reduction. Restriction regarding incandescent light, which used to be the main lighting, started and with active regulation on fluorescent light expected to begin, next generation lighting market is forecast to grow considerably.

At present, LED is in spotlight as the next generation lighting, rapidly expanding the market with its high efficiency and lifetime, replacing incandescent and fluorescent light. OLED does not contain harmful materials or light, and as lighting with high energy efficiency, it is receiving much attention as the most suitable next generation light for environmental and energy reducing policies. However, due to the steep price compared to LED, the market is growing more slowly than estimated.

According to UBI Research’s OLED Lighting Annual Report, published today (14th May), if 100mmx100mm is mass produced using equipment size of 1270mmx1270mm, OLED lighting panel production cost is analyzed to fall to US$ 5 or lower from 3rd year of mass production, and US$ 2.5 from 10th year (when 1 min tack time/single stack). This price is higher than US$ 1 – 3 of incandescent and fluorescent lights but much lower than approximately US$ 10 of LED lamp for interior lighting (60~70lm/W). Additionally, OLED lighting panel is currently being mass produced with superior efficiency and lifetime compared to incandescent and fluorescent lighting, and being developed with efficiency equal to LED. Considering these factors, if active mass production investments by OLED lighting panel companies take place, the market share within the lighting sector is estimated to rapidly increase.

OLED Lighting Annual Report forecast that in the early stages of mass production OLED lighting will form market focusing on areas where OLED lighting’s merits can be utilized in areas such as automotive, medical use, cosmetics, and exhibitions and not through main lighting. However, once mass production competitiveness is achieved, it is expected to quickly expand in main lighting market. Additionally, lighting market with high added value could be created through differentiation using flexible and transparent, and forecast the market to grow to show US$ 2,800,000,000 by 2020, and occupy approximately 10% of the total lighting market.graph

[Euroluce 2015] Kaneka Exhibits OLED Lighting Panel with 50 Thousand Hours of Lifetime

Marketing activities in Europe by Kaneka, one of Japan’s key OLED lighting panel companies, is attracting attention. Kaneka, the only company with active European marketing out of many OLED lighting companies in Japan, participated in Euroluce, a biennial event, in 2013 as well as 2015. Unlike most of Japanese OLED lighting companies whose promotion activities are focused on their domestic market, Kaneka is enthusiastic regarding lighting exhibition in Europe. This is analyzed to be because Kaneka is aiming for market expansion into Europe and North America, as well as Japan’s domestic market.

 

Kaneka explained that, “OLED lighting is suitable for European customers who consider design and diversity to be important as they have good energy efficiency, thin surface light source, soft light, and ability to produce various colors”, and revealed “increasing European consumers’ awareness of OLED lighting is the priority assignment and the main reason for this exhibition”.

[Euroluce 2015] Enter OLED Lighting Cheaper Than LED

An area has emerged where OLED lighting can exceed LED’s price competitiveness.

 

In LG Chem’s booth in Euroluce 2015 (April 14-19, 2015), a British company Mackwell’s OLED lighting applied emergency system was exhibited. Mackwell applied LG Chem’s OLED lighting panel to the emergency system used in cases of fire/blackout instead of existing LED lighting reducing the overall system installation cost. Mackwell is known to be preparing for commercialization.

 

LG Chem explained that “construction, excluding lighting, accounts for the 30-50% of total cost for interior lighting. LED lighting requires separate space for installation making construction cost a necessity, but as OLED lighting does not need additional construction this can be reduced. Although OLED lighting’s unit price is higher than LED’s, overall interior cost can be reduced if OLED lighting is used resulting in cheaper price”.

 

Regarding this, one LED expert observed that, “a certain distance is required between the LED lighting source and device, therefore LED installation space is additionally required and increases the cost” and “if the construction cost could be reduced from interior lighting it would be a great advantage”.

 

As shown, areas where merits of OLED lighting are actively used are emerging rapidly such as interior, medical, and vehicular lighting. If the cost competitiveness can be achieved from active investment by OLED lighting companies, not only the OLED lighting exclusive market could be created but existing lighting market could be replaced.

LG Chem, DIY KIT Released for Average Consumers to Experience OLED Lighting

In February 2015 LG Chem released OLED DIY Kit in Korea so that average consumers can directly experience the high quality of OLED light, closest to the natural light.

OLED is a light-emitting diode formed with organic semiconductors that emit light with its characteristic color. OLED is currently being used for TV and lighting, and receiving attention as the next generation diode. Particularly, spectrum distribution of OLED lighting is closest to the sunlight and produces a sense of stability of being under the natural light. Additionally, with its high color rendering index, colors can be accurately reproduced. Unlike the existing light sources, OLED is not hot to touch, and does not hurt eyes when looked directly. With no UV rays, it is a human-friendly light. It also produces almost no blue light compared to other sources and as such it is effective in eyesight protection. It is thin, light, flexible, and has potential for infinite designs.

In order for the average consumers to experience the OLED lighting with these advantages, LG Chem prepared the OLED DIY Kit with simplest possible components and connection method. Single Kit contains one LG Chem’s 100x100mm OLED module, Double Kit contains two modules for wider choice, and DIY Kit includes an OLED panel (a bulb equivalent), switch, and wiring set linked to connectors. It has an accessible and simple structure so that the light comes on just by linking the connectors two or three times, and connecting a micro 5-pin adaptor (compatible with normal Android mobile phone charger). The panel thickness of LG Chem’s 100x100mm module is only 0.88mm so that even with the neat aluminum case the thickness is 2.2mm. If the module and switch are attached by using wood, paper, or wire, or by reforming existing products, lighting of desired shape is complete.

To showcase environmentally friendly nature of OLED lighting, LG Chem minimized using extravagant packaging material and exuberant colors, and produced a simple cardboard box. It is an ultra-energy conserving light of high energy efficiency with less than 2.5W required for Single Kit, and less than 5W for Double Kit.

Of the OLED lighting industry, LG Chem is producing the world’s best performing OLED lighting panels with largest size and best lifetime surpassing other companies such as Philips and Osram. Due to their own key material production and advanced process technology, LG Chem also has an edge in price. In order to accommodate consumers’ requests, a testing team made up with staff of LG affiliated companies was formed and generated various DIY production ideas. The final DIY Kit was produced with improvements suggested by the testing team.

[Lighting Fair Japan 2015] LG Chem, 100lm/W OLED Lighting Panel Mass Production Possible in April 2015

LG Chem estimates mass production of highly efficient 100lm/W OLED lighting panel in April this year. In Lighting Fair Japan 2015 (March 3 – 6) LG Chem announced that they have achieved 2014 target of 100lm/W development, and that mass production will be possible from April 2015. Additionally, they presented the 140ml/W roadmap until 2017, and LG Chem is forecast to keep on leading the OLED lighting market.

Until now OLED lighting had lower efficiency compared to the existing fluorescent light (approx. 100lm/W) and LED (approx. 100lm/W or higher), and was mostly used as luminaire rather than down light. However, if active mass production of 100lm/W products begins, utilization as down light will also be possible.

In this exhibition, LG Chem showcased solution concept of down light, and not a luminaire focused exhibition. They also demonstrated OLED lighting’s competitiveness as down light by securing lifetime of 40 thousand hours. This is approximately twice as long as fluorescent light and rivals LED. The biggest issue for OLED lighting is the cost. If the price becomes competitive through active investment, it is analyzed that the OLED lighting market will grow rapidly.

According to UBI Research’s OLED Lighting Annual Report 2014, OLED lighting market is forecast to grow by 100% of compound annual growth rate and form US$ 4,700 million market in 2020.

LG Chem. announces new OLED lighting product milestones

LG Chem announced today that it achieved two important milestones in the development of OLED lighting products with the start of manufacturing of the 320 x 320 mm OLED light panel, the world’s largest available in the market, and the completion of the research and development phase for a new plastic-based OLED light panel.

The 320x320mm OLED light panel is 0.88mm thick panel and has an efficiency of 60lm/W, CRI over 90, and has output levels of 800lm with a nominal input (8.5V 1,600mA). The panel’s output can reach 1,200lm which is similar to a common 60-75 Watt incandescent lamp. This is significant because it marks first time that OLEDs can be considered as an energy-efficient / human-friendly light source available for general purpose use.

With LG Chem having begun mass producing the 320x320mm panels in January, the panels can be ordered at $680USD per panel, with a lower negotiated price for bulk orders.

 

 

LG Chem has also completed development of a truly flexible plastic-based OLED light panel and engineering samples are now available. LG Chem’s current bendable OLED panels (F6BA40, F6BA30) are thin-glass based that provides a limited bending radius of 75mm. The new flexible OLED panel has vastly increased the bending radius flexibility to 30mm because of the adoption of a plastic substrate for the panel, which also eliminates the danger of the panel shattering when excessive force is applied.

The main challenge of converting from a glass substrate to plastic was to maintain the performance levels of efficiency, luminance, and CRI. LG Chem has overcome this challenge by adopting its expertise in barrier and encapsulation technology.

The specifications of the LG Chem’s new plastic-based OLED light panel are 60lm/W efficiency, 75lm brightness, 3,000K in color temperature, and CRI over 85. Engineering samples are available at $250USD per panel. The mass production of the flexible panel is scheduled to begin in July 2015. The price will be adjusted accordingly once mass production starts.

Medical Lighting, will it make a breakthrough for the OLED lighting market?

The sizable growth for OLED lighting is expected in the medical lighting market.

At Lighting Japan 2015, Synqroa Corp. introduced Lucuria, the OLED lamp used for dental practice equipment, under the presentation title “Dental-free shadow lamps development and marketing by OLED lighting source”.

The presenter Mitsuhiro Koyama, Vice President Synqroa Corp., said that “OLED lighting is more appropriate than LED or halogen lamp for the medical purposes thanks to its properties including shadow-less, good color rendering and color temperature, and no blue risk. He also speculated “The competent lighting in the medical lighting industry is more about providing the optimal environment for doctors and patients than the price competitiveness.”

Synqroa estimated that the potential for the OLED lighting panel is about six million units with expected annual demand of about 350 thousand units for maintenance assuming that each hospital will use three units (five OLED panels per unit) in about 400 thousand dentists in the world as of 2013. In addition, they also analyzed the OLED lighting panel will take about 12 million units (25% of entire demand) among the demands for the lighting panels applied in operating rooms, patient’s rooms, NICU, etc.

Likewise, the expansion of OLED lighting market is expected to gain momentum if the OLED lighting panel is employed more actively in the medical lighting market equipped with merits of improving health care environments and protecting doctors’ and patients’ eyes.

OLED lighting, replacing LED is in the not too distant future

At SID2014, it was proved that OLED lighting has competitiveness in terms of efficiency and can compete with LED for the general lighting.

Konica Minolta developed 131lm/W OLED lighting panel last March. It also released an OLED lighting panel with efficacy of 139lm/W at the SID 2014 and drew more attention. Panasonic also presented on OLED, and drew more attention unveiling a prototype in Author interview.

Considering that the efficacy of currently commercialized LED lighting is about 80~130lm/W, it is analyzed that the fruitful result at the SID 2014 showed the potential of the OLED lighting becoming the general lighting instead of the LED lighting.

The most concerned issues of the OLED lighting are lifetime and cost. For the general lighting, 40,000hr, which the OLED panel makers target, is estimated enough considering replace period of the lighting, but the issue is the cost. Compared to the LED, the OLED lighting is expensive and currently forms a high-end lighting market. However, it is inevitable to down the cost for entering the general lighting market. Although LG Chem. announced a price reduction to 200$/Klm from 600$/Klm, investment of the OLED lighting makers in mass-production is vital to reform the general lighting market with the OLED lighting.

The OLED lighting panel has reached the level equal to the LED lighting. Now is the time that the OLED lighting panel companies make a turning point and can leap again by investing as they did with display.

did with display.
