35V Gate Pulse Modulator for LCD Panels

General Description

Features

^Flicker Compensation Circuit

The Gate Pulse Modulator (GPM) is specially designed

for the application of gate driver in TFT LCD panels. The

GPM is controlled by frame signals from timing controller

to modulate the Gate-On voltage that acts a flicker

compensation circuit to reduce the coupling effect between

gate lines and pixels. It also can delay theGate-On voltage

while power-on for achieving a correct power-on-sequence

for gate driver ICs. Both of the delay time for flicker

compensation and power-on-sequence are programmable

by external resistors and capacitors.

^Reduction of Coupling Effect Between Gate Line

and Pixel

^Programmable Power Sequence for Gate Driver IC

^Operation from 20V to 35V Positive Supply Input

^Adjustable Output Delay Time

^RoHS Compliant and 100% Lead (Pb)-Free

Applications

 TFT-LCDPanels
