A panel of patent cooperation alliance, Samsung's handshake

In January 12, 2006, the third largest in the world, China's Taiwan Province, the first large LCD panel factory AU Optronics (AUO) officially announced and the world's top two largest LCD panel suppliers of Samsung Electronics (Samsung Electronics Co., Ltd.) signed a patent cross licensing agreement both sides widely. In the LCD panel industry fierce competition between the two sides, will share the advantages of patented technology, to expand their technological innovation in the development of digital consumer electronics.

It is reported that the scope of this interactive license covers TFT-LCD and patents related to OLED technology, especially in the application of LCD TV technology. Prior to this, AUO announced on October 13, 2005, the Yokohama International Exhibition in October 19th will display (FPD International 2005) in the public display of a new generation of ultra wide angle AMVA technology, applied to HDTV 4ms speed response time and restore the true color and image enhancement of panel built-in stereo image processing system.

AUO said, the independent research and development of AMVA (AUO Advanced MVA Technology) TV panel super wide angle technology has been in the 32 inch panel production, the technology can provide a liquid crystal panel low color and high contrast for large size HDTV LCD tv. Based on original MVA, AUO with original pixel and driving principle, designed to produce 8 pixels (8 domains, eight MVA domain) panel, solve the traditional MVA Technology (so far is the four major domain MVA) is easy to produce color deviation in lateral view. In addition, AMVA technology has also further solved the color and other special color distortion. The color filter (Color Filter) combined with innovative design, with the pixel and optical compensation film, AMVA can effectively reduce the leakage of light in the dark state of the panel, greatly improve the level of the dark state picture performance, and the highest contrast LCD panel from 800:1 to 1200:1 in one fell swoop.

In addition, with LED backlight technology, AUO is still 46 inches LCD TV panel on the implementation of the 10000:1 high dynamic contrast, which makes the contrast performance of LCD TV and traditional CRT TV and plasma TV compete. The characteristics of high dynamic contrast technology makes full use of LED backlight brightness can be adjusted independently, using regional type backlight technology different from the traditional monolithic backlight, backlight will be divided into many small areas, can independently control the back light, not only to at least 50% more power, can make the picture level performance of a substantial increase of 64 times, so that the image has a similar three-dimensional effect, achieve up to 10000:1 dynamic contrast.

In order to meet the upcoming World Cup in 2006, will become the mainstream in AUO 37 Inch LCD TV panel as the platform, in the standard WXGA (1366 * 768) and Full HDTV (1920 x 1080) two kinds of resolution, respectively, to provide customers with fast response time can reach 4ms. The core of this technology, which is simulated by AUO unique dynamic vision compensation system on pulse of traditional CRT TV display screen, thereby reducing ghosting, and greatly improve the dynamic image quality, makes the effective response time is equivalent to the traditional CRT TV (about 4ms) quality performance.

According to the color and image processing, AU Optronics has developed a breakthrough technology panel built-in image processing system. In the show's 37 Inch HDTV (1920 x 1080) LCD TV panel, AU Optronics has built-in image processing system for real-time processing of video signal into the panel, improve the image of three-dimensional, true color contrast and highlight the high color saturation in fine grey class time. Because the system uses real-time processing, it does not need any temporary space, thus saving the cost of integrated memory IC. In addition, the system can approach to change the dynamic image according to different characteristics of human vision, overcoming the LCD TV screen in the dark state cannot appear subtle due to the gray scale image distortion problem, on the night of the picture and dark scene performance is more delicate and true. Because the system can automatically adjust the brightness of the CCFL backlight, so the more energy saving and environmental protection features. The company said, the technology will be mass production in the second quarter of 2006.

AUO executive vice president Dr. Xiong Hui pointed out that the LCD TV to replace the traditional CRT TV, there are 3 technical difficulties need to be overcome are the color cast phenomenon and wide visual angle technology dynamic image picture ghosting and dark state picture level distortion, 3 new technology and AU Optronics this show, just this paper proposes a complete solution, it is expected that these great breakthrough research results will lead the trend of the future development of digital television, but also the future image of high definition digital television the merits of the 3 crucial key technologies.
