Pixel Conversion
The Pixel Conversion IC6000, which resides on the Digital Board represented in Figure
16, processes the RGB output from the Global Core IC4004.
The Pixel Converter IC6000 is responsible for handling the White Balance and Picture
Control i.e. the Contrast, Brightness, Backlighting and Video Sharpness. In addition, the
LCD Artificial intelligence circuitry incorporated within this IC monitors and detects the
luminance distribution in real time and adjusts the gradation and luminance accordingly.

This IC also handles the Aspect ratio (4:3/JUST/FULL) and the I/P conversion.
Resizing The Screen
Resizing the image on the LCD Screen is accomplished by IC6100 located on the DG
board. The Aspect Zoom and the LCD Frequency Drive logic reside on this board.
IC6400 is a Low Voltage Differential Signaling circuit (LVDS) designed to provide proper
drive and impedance matching when transmitting either data or signaling from one
board’s processor to another.
