7、 only ATV) 2.3 General Specification 2.3 General Specification The LCD TV is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Flourscent Lamp(CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive display type which

8、is operated in the normally black mode. It has a 31.51 inch diagonally measured active display area with WXGA resolution. (768 vertical by 1366 horizontal pixel array) Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes. Gray scale or the luminanc

9、e of the sub-pixel color is determined with a 8-bit gray scale signal for each dot, Therefore it can present a palette of more than 16.7M(true) Colors. It has been designed to apply the 8Bit 1 port LVDS interface. It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle
