摘要

将三阶驱动原理应用于TFT-LCD 电测波形的设计

并通过实验验证了其有效性。设计过程中

直接通过栅极电压上拉

将

产生的Feed Through电压用来补偿栅极电压关闭时使

产生的Feed Through电压。这样无需通过修正

com

电压来补偿(栅极电压关闭时产生的Feed Through电压)

避免了获取

参数难的问题。

Abstract

Three-stage driver principle is used in the electromotive waveform design of TFT LCD and verified by the experiment. In the proposed design

when gate voltage is closed

the Feed Through vol-tage of

is compensated by the Feed Through voltage of

. The voltage of

is generated by the increase of gate voltage directly. Therefore

rectify of

com

is unnecessary

then

the difficulty of extraction

parameter is avoided.
