为研究画面闪烁与光照漏电流(
I
off-p
)的关系
文章进行了一系列的实验。首先利用色彩分析仪(CA310)分别测试了3张面板正、反两面的闪烁。其次通过测量闪烁随背光源亮度的变化研究了其与光照的关系。同时还采用光敏放大器测试了面板正、反两面闪烁画面下的亮度信号
并给出了原理性解释。最后采用半导体参数设备对TFT进行了
I-V
特性测试。所有的实验结果均表明
I
off-p
过大能够导致像素电压无法有效保持
从而使正负帧的亮度产生较大差异
最后造成闪烁偏高。
In order to study relationship between Flicker and
I
off-p
in TFT-LCD
a large amount work had been made. Flicker of obverse and reverse of 3 panels were observed by CA310. The relationship between Flicker and BLU brightness were researched. Brightness of obverse and reverse of 3 panels were also researched by photo sensor amplifier in Flicker pattern.
I-V
curve was measured by semiconductor parameter equipment. All results show that
I
off-p
was too large to pixel voltage couldn't hold
then brightness of odd frame and even frame was different
and Flicker became serious.
