G Flex2 is the up to date curved smart phone equipped with the latest 64bit Octa-Core CPU and Snapdragon 810 processor from Qualcomm. The frontal curvature of 700R is also the same as in the G Flex, but the backside is 650R, increasing the sense of grip. For its 700R display, it provides much better sound quality by reducing the gap between the user’s face and the phone. With the self-healing back cover as in the G Flex, it just removes various scratches occurred in daily life. 

LG Electronics and Samsung Electronics sold the curved smart phones in 2013 at the same time. LG Electronics’ G Flex was the same panoramic design as now but Samsung Electronics competed by releasing a smartphone curved from left to right to emphasize a firm grip.

Plastic OLED의 향연

LG전자의 비밀 병기 G Flex2가 CES2015에서 전격 공개되었다. LG디스플레이에서 생산하는 plastic OLED로 만든 smart phone G Flex2는 2013년에 시판된 G Flex에 비해 사이즈는 5.99인치에서 5.5인치로 작아졌으나 해상도는 HD급에서 FHD(403ppi)로 오히려 향상되었다.

 

 

 

 

G Flex2는 Qualcomm사의 최신 64bit Octa-Core CPU와 Snapdragon 810 processor이 탑재되어 있는 최신 curved smart phone이다. 디스플레이가 있는 전면부는 700R로서 G Flex와 동등하나 후면은 650R을 적용하여 그립감을 향상 시켰다. 전면부의 700R은 스피커와 마이크를 얼굴에 더욱 밀착 시켜 송수신에서 더욱 좋은 음질을 제공해 줄 수 있다. 뒷면부는 G Flex에 적용되었던 self healing 커버가 부착되어 있어 생활 공간에서 발생하는 각종 스크래치를 없애 줄 수 있다.

2013년에 LG전자와 삼성전자가 동시에 curved smart phone을 판매했다. LG전자의 G Flex는 지금과 동등한 파노라마 형태의 디자인이었나, 삼성전자는 그립감을 강조하기 위해 짧은 방향이 휘어진 제품을 출시하여 경쟁하였다.

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.

Audi’s Love for OLED

 

Audi has particular affection for OLED than any other automobile companies. For instance, it has announced the concept car Audi Q7 with its rear lights using OLED light panel and the recently unveiled concept car Prologue is equipped with the flexible OLED display featuring the resolution of 8.9 x 5.6-inch 287ppi (2560 x 1600) and three sheets of rigid OLED display.

For this CES 2015, the letters of Audi was displayed three dimensionally using the OLED light source at the exhibition space intended for R8 LMX together with the phrases of ‘OLED View 2’ and ‘Audi Matrix OLED.’

According to the personnel from Audi, OLED will be used actively as a light source for it has a beautiful quality than any other light sources.

 

의료용 조명, OLED lighting 시장의 돌파구 되나?

의료용 조명시장에서 OLED lighting이 크게 성장할 것으로 예상된다.

Lighting Japan 2015에서 Synqroa Corp.는 “Dental-free shadow lamps development and marketing by OLED lighting source”라는 주제로 발표를 하며 치과 치료 장비에 사용되는 OLED lamp인 Lucuria를 소개했다.

발표자인 Synqroa Corp.의 vice president Mitsuhiro Koyama씨는 “OLED lighting은 shadow-less와 good color rendering and color temperature, no blue risk의 장점이 있어 LED나 할로겐 램프보다 의료용으로서 적합하다”라고 발표했다. 특히 “의료용 조명에서는 가격경쟁력보다는 의사와 환자에게 적합한 환경을 제공해줄 수 있는 조명이 더 경쟁력이 있으며, OLED lighting이 의료용 조명에 적용되면 큰 시장을 형성할 수 있을 것”으로 내다봤다.

Synqroa는 2013년 기준 전세계 치과 수는 약 40만개로서 각 병원당 3개의 unit(각 unit당 5개의 OLED panel 사용)을 가정한다면 OLED lighting panel의 potential은 약 600만개이며, 유지보수로서 연간 약 25만개의 OLED lighting panel의 수요가 있을 것이라 예상했다. 또한 수술실, 병실, NICU 등 의료용으로 적용되는 lighting에 panel에 대한 수요 중 OLED lighting panel은 1,200만개(전체 수요의 25%)가 될 것으로 분석했다.

이처럼 OLED lighting panel이 health care environment 개선과 환자와 의사의 눈을 보호해줄 수 있는 장점을 바탕으로 의료용 조명시장에 적극적 적용이 된다면 OLED lighting 시장 확대가 더욱 탄력을 받을 것으로 예상된다.

Audi의 OLED 사랑

Audi의 OLED 사랑은 다른 자동차 업체에 비해 각별하다. Audi는 오래전부터 OLED 광원을 리어 램프에 사용한 컨셉카 Audi Q7을 공개한 바 있으며, 최근에는 컨셉카 Prologue에 8.9 x 5.6 inch 287ppi (2560 x 1600) 해상도의 flexible OLED와 3장의 rigid OLED display를 탑재했다.

이번 CES2015에서는 R8 LMX를 전시한 공간에 별도로 OLED 광원만으로 Audi란 글자를 입체적으로 표현하였으며, 이 장소에는 OLED View 2와 Audi Matrix OLED란 문구를 두었다.

Audi 관계자에 따르면 OLED 광원에서 나오는 빛은 어떤 광원 보다 아름답게 때문에 Audi는 OLED 광원을 적극적으로 채택할 것임을 언급하였다.

[CES2015] 삼성과 엘지의 엇갈린 OLED 사랑

한국에서 세계 최초와 최고, 최다라는 수식어를 모두 사용할 수 있는 유일한 전기전자제품은 OLED인 것 같다. 그것도 한 업체가 아닌 두 업체가 모바일 디바이스 영역과 TV 영역에서, 그리고 둘이서 flexible(plastic) 디바이스 부분에서 자웅을 겨루고 있다.

하지만 삼성디스플레이와 LG디스플레이가 OLED 패널을 제품화한 시기는 서로 달라도 너무 다르다. 유리 기판에 제작한 소형 AMOLED 패널은 삼성디스플레이가 주도하고 있다. LG디스플레이도 초기에는 참여했지만 곧 사업을 접고 말았다. 그 후로 삼성디스플레이만의 외로운 질주가 계속되고 있고, 삼성디스플레이 관계자들은 같이 OLED 사업을 끌고 갈 선의의 경쟁 파트너를 뜨겁게 갈망했다.

OLED TV 분야에서는 입장이 완전히 뒤 바뀌었다. LG디스플레이는 모바일용 AMOLED 사업 실패를 교훈 삼아 파부침주(破釜沈舟)의 각오로 아무도 상상하지 못한 oxide TFT와 WRGB OLED, hybrid encapsulation 기술로서 UHD TV까지 만들 수 있는 대형 OLED 패널 상품화에 성공했다. 반면에 OLED 원조인 삼성디스플레이는 대형 OLED 패널 양산을 중지하고 긴 동면에 들어갔다. 이번엔 LG디스플레이가 혼자만의 마라톤에 들어 갔다. 디스플레이 산업의 꽃인 TV용 시장에서 외로운 독주는 몇 년간 지속될 것으로 예상된다.

이번 CES2015에서 LG전자 부스는 OLED 패널이 들어 있는 curved UHD OLED TV와 G Flex2, G Watch를 중심으로 구성되었으며, OLED TV의 우수성을 홍보하기 위해 LCD TV와의 화질 비교와 시야각 비교 코너를 만들었다.

삼성전자 부스는 QD-BLU LCD TV인 SUHD TV를 중심으로 부스가 구성되었으나, 부스 한 곳에는 SUHD TV와 기존 LCD와 OLED, PDP TV와의 화질 비교 코너가 있었다.

이제까지 OLED가 최고의 화질인 것을 강조하며 사업을 진행했던 삼성전자가 SUHD TV를 부각하기 위해 고육지책으로 OLED TV와 화질을 비교까지 하게 되었다. 물론 전시장에 전시되어 있는 OLED TV와 PDP TV는 SUHD TV에 비해 화질이 나쁘게 나타났다. 그러나 OLED TV는 삼성에서 만든 제품으로 예상되어 오히려 삼성디스플레이의 대면적 OLED 패널 제조 기술이 LG디스플레이에 비해 매우 낮다는 역설적인 코너로 보여, 향후 삼성디스플레이의 OLED 사업에 네거티브 영향을 크게 미칠 것으로 예상된다. LG전자 부스에서 OLED TV를 본 사람이면 누구나 LG디스플레이가 생산하는 TV용 OLED 패널 화질이 얼마나 우수한지를 쉽게 느낄 수 있기 때문이다.

LG의 OLED를 바라보는 시각이 바뀐 것은 CES2015 개막 전날 개최된 LG디스플레이 기자 간담회장에서 명암이 명확히 구분되었다. 앞 단상은 LG디스플레이 로고와 OLED라는 글자로 모자이크 되어 있었다. 이젠 LG디스플레이가 OLED를 책임지겠다는 의지가 강하게 엿 보였다.

비록 LG디스플레이와 삼성디스플레이가 OLED 패널 산업에서 추구하는 영역은 다르지만 모바일용 소형 패널에서 대면적 OLED 패널까지 두루 생산할 수 있는 산업 인프라가 형성되어 미래의 한국 디스플레이 산업이 지속 성장 가능함을 확신할 수 있게 된 것이 이번 CES2015의 최대 결실이다.

 

[Analyst Column] 삼성디스플레이, 디스플레이 미래를 쏜다


매해 11월이면 충청남도 아산에서 삼성디스플레이가 후원하는 DVCE (Display Valley Conference & Exhibition) 2014가 개최된다. 10회를 맞이한 DVCE는 디스플레이 산업 메카로 자리잡은 충청남도의 주요 행사로서, 삼성디스플레이의 적극적인 지역 발전과 디스플레이 산업 발전을 위해 만들어진 국제 학술 행사이다.

DVCE 첫날인 11일에 삼성디스플레이 연구소장인 김학선 부사장은 “Display Beyond Imagination”이란 제목으로 키 노트 연설을 통해 디스플레이가 가야 할 미래를 인문학적 고찰을 통해 제시하였다.

대부분 디스플레이 관련 학회나 세미나에서는 하드웨어와 기술에 대한 내용이 일반적이어서 향후 디스플레이가 발전해 나가야 할 방향을 제시해 주는 예는 없었다. 김학선 부사장은 키 노트에서 미술사와 디스플레이를 비교하며 아날로그와 디지털이 융합할 수 있는 신 기술 시장을 정의하였다. 과거 유명한 미술가들이 다양한 기법을 개발하며 창의적인 작품을 창작한 것처럼 디스플레이에도 새로운 기능을 부가하여 창의적인 디스플레이가 만들어져야 함을 언급하였다.

특히 디스플레이를 개발할 때는 빛과 인간의 눈에 대한 근본적인 이해와 고찰을 통해 human interface로서 친인간적인 제품으로 거듭나야 함을 강조하였다.  김부사장은 미술가들이 작품을 만들 때 이용하는 조명과 원근법, 입체화법, 질감 등을 디스플레이에도 응용하여 조명과 눈, 바이오 센서, 햅틱 센서 등 다양한 기능을 디스플레이에 내장한 융합 제품을 미래 상품으로 비젼을 제시하였다.

김부사장은 최근 한국 디스플레이 산업이 축소되어 가며 새로운 제품이 나오지 못하는 것에 대해 매우 유감스럽게 생각하며, 디스플레이 산업을 부흥 시키기 위해서는 디스플레이를 개발하는 엔지니어들로 인문학적 고찰을 통한 융합과 조합을 시도해야 함을 피력했다.

KITECH, Developed the world’s first refining technology for organic light-emitting material using ILs for OLED TV

Dr. Taewon Kim’s team of photovoltaic energy convergence research group of Korean Institute of Industrial Technology (KITECH, President Yong-Soo Lee) developed an original technology to refine organic light-emitting materials in bulk for fine OLED TV at low price.

Dr. Kim’s team established a new concept for the refining technology by using Ionic Liquids (ILs), and it can solve issues of high cost·low yield rate arisen in production of the organic light-emitting material for the OLED TV.

Ionic Liquids are liquids that only consist of positive and negative ions at room temperature and stays in liquid form at high vacuum (~100℃) with almost no volatility. Recently, ILs became a future clean solvent in green chemistry field with a strength of good solubility for high molecular substance and a feature of metal salts.

Until now, ‘sublimation refining method’ has been used to get high purify organic light-emitting material by utilizing the difference of sublimation points between vaporization and solidification of a material. However, cons of this method are low yield rate and very high production cost because it is impossible to realize complete auto and continuous process.

To address this issue, Dr. Kim’s team started developing the large scale refining technology for the organic light-emitting materials at low cost since 2011 and applied for original patent in December, 2012. Their effort on verifying the possibility of the technology’s application produced this result in 19 months.

The key of the result is the application of the high purity refining technology on the organic light-emitting material for the OLED TV by focusing on the non-volatile feature of ILs at high vacuum·high temperature.

This technology uses a principle of separating impurities in the order of vaporizing the organic light-emitting material in a vacuum chamber; dissolving it in a liquid filter of ionic liquid; and recrystallizing supersaturated material in the liquid. It enables to get 99.95% of high purity organic light-emitting material through one refining process.

It is a completely new concept of large scale refining method based on the non-volatility characteristic of ionic liquid at high vacuum·high temperature.

The team is credited with the success of new technology development which can overcome the cons of the existing sublimation refining method including refinery yield rate, automation and continuous process of equipment, and efficiency of mass production. It is also expected to bring a huge cost reduction effect by recycling; collect and reprocess during refinery process, of the expensive but non-volatile ionic liquid.

According to “2014 OLED Emitting Material Annual Report Market Forecast (~2020)” by a professional OLED market research firm, UBI Research, the OLED emitting material market is expected to grow to 1.3 trillion won in 2017 from 2014 estimation of 543 billion won. Forecasted annual growth rate is over 30% and experts see that the growth will be much larger if large size display market including the AMOLED TV expends in full-scale.

Dr. Taewon Kim, said, “this technology increased the yield rate and decreased the production cost by more than 50%. And an ultimate goal is to reduce the current price by one tenth” and “technology development is in progress with companies.” He also said, “the success is a game changer with enormous potential to turn the OLED TV market-to-explosively grow” and “based on the low-cost and large scale refining original technology, domestic businesses will largely contribute to preoccupy the global market of forward-backward industry regarding the OLED TV.”

The team currently applied 16 cases for patent with related process․equipment technology in and out of the country and plans active technology transfer to related businesses.

LG Display forecasts blooming of OLED TV market in 2015

OLED TV market is expected to begin flourishing from the end of 2015.

At the presentation of LG Display’s performance in Q2 held on 23rd at LG Twin-Tower, Yeouido, an executive director of strategic marketing group of LG Display (LGD), Youngkwon Song, emphasized, “LGD is putting efforts to realize the economy of scale and to cut cost including lowering material cost regarding the OLED TV business” and “a significant condition will be developed by the end of 2015 and early 2016.”

Mr. Don Kim, the CFO and a senior vice president of LGD said that “from our point of view on the OLED, the current levels of expected performance and yield rate are at satisfaible level, but innovation in pricing is what we concentrate more” and “by the end of 2015 or early 2016, when the operation is in full capa., we can reach the economy of scale and bring a significant performance.” Mr. Kim also hinted a soon-to-be bloomed of LGD’s OLED TV market.

LGD started supplying panels for the OLED TV to major Chinese TV set makers and plans to operate M2 line for mass-production in this third quarter. It also continuously leads the OLED market with scheduled launch of 55”/65”/77” curved UHD OLED TV.

In the meantime, sales for Q2 in 2014 was 5.979 trillion won which is declined by 9% from the Q2 in 2013 but increased by 7% from the Q1 in 2014. And operating profit was recorded surplus consecutively for nine quarters at 163.1 billion won.

Launching of Gionee’s ultra-thin AMOLED smart phone (5mm) is imminent

Ctimes, a Chinese medium, reported that a Chinese smart phone maker, Gionee, will introduce an ultra-thin smart phone modeled GN9005.

GN9005 used AMOLED panel and is 0.55mm thinner than 5.55mm of the previous model, which was introduced as Elife S5.5 last February.

It is noticeable that 4.8” HD AMOLED panel is applied which is smaller than the 5” FHD Super AMOLED applied to the previous Elife S5.5. In general, the AMOLED panels produced by Samsung Display are named super AMOLED. However, no particular name for the AMOLED panel applied to GN9005 and its low performance indicate that the panel is highly likely to be supplied by AUO.

It is known that AUO has started supply to a Chinese maker from last June but any specifics on the maker has not been revealed.

A Chinese smart phone maker, BBK, drew attention with 5.75mm VIVO X3 after the launch of 6.18mm Ascend P6 by Huawei last year. Followed by launching, Gionee introduced the 5.55mm Elife S5.5 in February and will launch 5mm GN9005 and that fierce competition will begin soon in the ultra-thin smartphone market in China.140722_GioneeElifeS5.5vsGN9005

Sony unveils Head Mounted Display (HMD) for medical care

Sony displayed a system, which enables you to check endoscope video through Head Mounted Display (HMD) at International Modern Hospital Show 2014 held from July 16th to 18th, 2014. For the existing endoscopy surgery, posture restriction exists because the procedure requires external monitoring. With Sony’s new product, surgery, however, can be performed without the posture restriction.

This specialized product for medical purpose weights only about 490g which enables an operator to perform in a standing position. It doesn’t fully cover eyes of an operator by changing the shape of wearable belt so that the operator can visually check surgery device by lowering the eyes without taking it off.

This medical HMD is installed with Sony’s OLED display and shows images on the OLED display individually thus crosstalk is not that large and doesn’t induce dizziness during its use.

 Sony consulted with doctors to develop this system and said that demand for this competitive system will increase as 3D endoscope increases.

LG Display successfully developed world’s first flexible and also transparent OLED.

LG Display succeeded in developing world’s first flexible and transparent OLED.
LG Display announced the technological development of world’s first 18-inch flexible OLED and transparent OLED of same size, disclosing at the ‘national project workshop for transparent flexible display development’ to be held from July 10 till July 11.
It is considered that LG Display secured the foundation technology for developing a large screen transparent flexible display through the simultaneous development of flexible and transparent OLED this time.
The flexible OLED that LG Display developed is 18-inch in size with HD resolution (1200 X 810) nearly 1 mega pixel quality, and this is the largest OLED in the world, realizing the radius of curvature of 30R. This means it can be rolled up to a radius of 3cm with no operational complications and implies that it is possible to implement a large panel rollable TV over 50 inches in the future.
In order to realize maximum radius of curvature even on 18-inch screen, LG Display used Polymide film of polymer materials on a substrate that TFT and organic matters are deposited, reducing the thickness and increasing flexibility drastically.
Furthermore, this concurrently developed transparent OLED is of same size and resolution as flexible OLED and the transparency is 30% or higher realized by self-developed transparent pixel design technology. It is a radical increase of transparency, given that transparency of existing LCD based transparent display is about 10% or so.
LG Display maximized the degree of completion by lowering the haze caused by circuit element and film down to 2%.
The transparent flexible display is a national project of the future industry-leading technology development program promoted by the Ministry of Trade, Industry & Energy and the Korea Evaluation Institute of Industrial Technology, and LG Display is the leading participants of total 36 organizations of industries, academies, and institutes, aiming to develop a large 60-inch transparent and flexible display by 2017.
According to In-Byung Kang, Senior Vice President and Head of the R&D Center at LG Display, “Pioneered OLED TV market, LG Display is leading future applied technology of OLED,” and “Though there still are many challenges to be resolved, we are confident in developing transparent flexible display of over the 60-inch screen UHD (Ultra High Definition) screen with transparency of 40% and a curvature radius of 100R by 2017.”
