At the same time many other countries are also included in the itinerary of this reform schedule, and as it a forcibly reform project. The Advent Of The Era Of HDTV Since 2000, to improve the image quality of TV broadcasting, the broadcasting started to transform the signal from conventional analog signal into digital signal,. This reform of signal technology has been developed as a global-wide project today: In 2004 the United States has conducted such technological changing. In 2006 FCC has transformed the National television Broadcast signals into HDTV digital signal, and will fully stop to broadcast the analog signals in 2009. Taiwan will start to broadcast the digital HDTV in 2008. China officially launched conversion project of digital television signal in 2006. In 2008 Beijing Olympic Games comprehensive TV will broadcast signals with high-definition digital.

The global demand of replacing digital TV is about 200 million The global demand of replacing digital TV is about 200 million every year. The United States accounted for about 40 million, China accounted for about 30 million demands of the market. The next few accounted for about 30 million demands of the market. The next few years China will overtake the United States as the world's largest years China will overtake the United States as the world's largest market demand market demand With the continuously improvement of this signal conversion, TV reception system will also change following the comprehensive reform. Size of TV increases from the original small size The Size of TV increases from the original small size (20~30) to large size(>50) and even more than 70-inch Traditional CRT monitors have been eliminated and gradually replaced by LCD monitor. replaced by LCD monitor. The coming of Digital TV Generation

Existing digital TV technologies have PDP, TFT, DLP, LCoS. Widescreen which is a American professional magazine released the technical evaluation report in every performance comparison with CRT, PDP, TFT,DLP,LCoS. The report shows that LCoS leads other technology, and were classified as the best. Comparison Of Digital TV Performance Comparison Of Digital TV Performance

PDP: Its size is limited to the range of 42-inch to 80-inch. Technology is almost controlled by Japan. The product lifetime is relative short. For large-size, cost is high. LCD: Its a capital-mass industry. To set up a 50-inch TFT-LCD production line, the capital investment almost require RMB500 billions. At present, the LCD market is dominated by Japan, South Korea and Taiwan. It,s not easy to get into the industry for a new comer. The investment recovery takes quite long time. At present, the LCD market is dominated by Japan, South Korea and Taiwan. It,s not easy to get into the industry for a new comer. The investment recovery takes quite long time. DLP: The technology is exclusively owned by TI. For large-size rear projection TV application, the disadvantage of single chip DLP technology are insufficient brightness, bad color saturation, color-break effect, difficult to upgrade resolution to 1080P and so on. Its suitable for data projector but not suitable for rear projection TV. to upgrade resolution to 1080P and so on. Its suitable for data projector but not suitable for rear projection TV. LCoS combined with H LCoS: This technology is combined with the IC design and TFT-LCD technology. High-resolution, high-contrast, high long device lifetime are its characteristic. Its suitable for large size rear projection TV application. brightness, long device lifetime are its characteristic. Its suitable for large size rear projection TV application.

Why LCoS? LCoS: Liquid Crystal on Silicon Combination of two major technologies: IC manufacturing and liquid crystal display technology Meet the requirements of HDTV high-definition, high-resolution.With the potential for low-cost.
