LG Display¡¯s AMOLED Panel Development Trend 2009.11.11
 

LG Display showcased various AMOLED panels at the IMID 2009 and the FPD International 2009, expressing its clear intention to engage in AMOLED business.

Its most eye-catching panel was a 15-inch AMOLED panel which will be used in LG Electronics¡¯ TV products later this year. LG Display emphasized that the TV equipped with its 15-inch AMOLED display is the largest-ever AMOLED TV introduced so far and is the first to be released since Sony¡¯s 11-inch AMOLED TV.

The company also exhibited a 15-inch RGBW AMOLED panel. In the existing R,G,B vapor deposition method for AMOLED, each of R, G, B is manufactured separately, allowing the optimization of color display and efficiency. However, the method has the disadvantage of using shadow mask for realizing R, G, B pixels, making it difficult to achieve high resolution and to be applicable to large-area panels. To solve these problems, the RGBW method using white light was used. The method does not require shadow mask so that a large-area OLED can be formed without the sagging of a mask plate of the shadow mask.

At FPD International 2009, LG Display showcased a 20.7-inch medical AMOLED panel for the first time. The panel features QSVGA (2560 x 2048) 5M pixel resolution and a contrast ratio of higher than 100,000:1, proving that it satisfied high resolution and high contrast ratio criteria required for medical display.


At the event, LG Display also displayed a 15-inch transparent AMOLED panel for the first time. According to the company, it is the first time that a transparent AMOLED panel with such a big size is exhibited although a number of small-size ones have been developed and displayed before. The panel has a 30 percent transparency and used the paste seal technology for encapsulation.

As for small-sized panels, the firm displayed a 4.3-inch flexible AMOLED panel, a 4.3-inch AMOLED panel for mobile phones using image improvement technology, and a 2.7-inch AMOLED display for delta-structure digital cameras. LG Display reportedly plans to mass produce 4.3-inch and 2.7-inch AMOLED panels in the first half of next year.
