A LCD Television System Design For European Market

From the year of 2001 , the LCD display panel technology advances rapidly in Taiwan and South Korea, the defects of its narrow viewing angle and long response time, etc. have been improved greatly. Now the LCD TV has won great favour from customer because of its low radiation, wide viewing angle, high brightness, high contrast, brilliant color and soft picture quality. Gradually the LCD TV has been accepted by common family and is popular in the world.The type of LCD TV described in this article is designed to meet European market's requirement.It uses DPTV-SVP-EX52 chip made by Trident Company as chief IC. We fully considered the European market's special requirements and developed this high end type of LCD TV which is suitable for European market and also compatible in East Asia, South Asia, Hongkong market. It has multi interfaces including VGA, YPbPr, VIDEO/SVIDEO, Scart and HDMI. As regard to this HDMI interface, we are the first in China to get the ATC certification from international HDMI organization.This aritcle is a summary about my efforts in this two and a half years. It firstly introduces the background of Chinese TV manufacturers' efforts in developing European market. Then it states the whole scheme diagram in hardware theory and design, especially introduce the hardware design process about main central chip DPTV-SVP-EX52. Also analyzes the adopted IC's characters and depicts details in design process. Finally it analyzes the main typical bug issue in the system's typical authentication testing and gives out the solving methods.
