摘要

研究了大尺寸TFT-LCD显示器制造工艺中LC Pattern对边角Zara domain的影响。实验表明

当大尺寸TFT-LCD显示器制作工艺中LC Pattern中边角处无液晶滴时

边角Zara domain发生率高

当LC Pattern在边角处添加液晶滴时

边角Zara domain发生率降低

通过调整边角处液晶滴到玻璃基板有效面积的距离

到一定范围时边角Zara domain明显降低

通过优化

确定当使用LC Pattern 5时

边角Zara domain发生率最低

为2.5%

经过高温炉处理后

边角Zara domain完全消失。

Abstract

The dependence of Zara domain(corner) on LC pattern has been studied.The experimental results show that

when no LC drop in the corner of LC pattern

Zara domain (corner) easily occurs.By adding LC drop in the corner of LC pattern

the incidence of Zara domain(corner)can be reduced.By adjusting the distance to Active Area

the incidence of Zara domain (corner) is the lowest. On the conditions for LC Pattern 5

Zara domain(corner) is 2.5%

and then disappears after oven treatment.
