GENERAL DESCRIPTION
The driver offers all-in-one chip solution of 480RGBx272 for color TFT-LCD panel. This chip incorporated with
digital timing generator, source and gate driver, power supply circuit and embedded serial communication
interface for function setting. The source output support real 8-bit resolution and 256-gray scale with small
output deviation are designed to support higher color resolution. The power supply circuit incorporated with
step-up circuit, regulators and operational amplifiers to generate power supply voltages to drive TFT LCD.
