摘要

画面闪烁是TFT-LCD的重要缺陷。文章通过一系列的实验

观察了Photo-

off

、

com

、Flicker、V

之间的关系

并给出了机理解释。

的变化产生V

导致

com

的漂移

形成闪烁

但如果

com

的均匀性较好

这种闪烁理论上可以通过

com

调整消除。Photo-

off

造成在正、负极性电压下像素的电压保持特性不同

引起

com

进一步的漂移和闪烁。通过降低Photo-

off

和提高

可以改善闪烁现象。

Abstract

Flicker is the serious defect of TFT-LCD. In this paper the relations among photo-

off

com

flicker and V

had been observed through a series of experiments

and the mechanism explanation is demonstrated. The change of

brings

results in the shift of

com

and flicker

however

this kind of flicker can be avoided theoretically by the

com

adjustment if the uniformity of

com

has no problem. The pixel's voltage holding characteristic has difference between the positive and negative frames due to the Photo-

off

so the further shift of

com

and flicker are happened. The flicker phenomena can be improved by decreasing the value of Photo-

off

or increasing the
