IV Operating Principle
The single device output analog signals through ADC element (Analog Digital Convert)
conversion to become a digital signal and the video signal is via Video Decorder
conversion. I t has become the same digital signal, these signals via Scaler IC as zoom
in or out action and digital image processing, then through the cable line transmission
LVDS signals to one of the LCD module. The last by the clock controller (Timing Controller,
TCON), the clock signal is transmitted to the drive IC on the panel and turn on Backlight for
LCD module light source by Scaler control.
