GENERAL DESCRIPTION

ST7282T2 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.
