摘要

针对共面转换IPS(In-Plane-Switching)液晶显示模式取向膜

利用反射椭偏消光法测量了取向膜表面的光学各向异性

DΔ

值。研究了在不同摩擦条件和亚胺化温度条件下

取向膜表面光学各向异性值

DΔ

值的变化。研究结果表明

随着亚胺化温度升高

DΔ

值呈现下降趋势。在摩擦强度各因子中

压入量和转速对于

DΔ

值影响较大。

DΔ

值可作为一种定量化评价取向膜取向状态的方法

并可作为生产过程中对于液晶稳定性取向的管控方法使用。

Abstract

The anisotropy

DΔ

of rubbed polyimide film for In-Plane-Switching(IPS) liquid crystal alignment was measured by reflection ellipsometry under the varied conditions of rubbing and imide temperature. It is showed that

DΔ

decreases with increasing imide temperature under the same rubbing condition. The penetration depth and the roll rotation speed play a key role in

DΔ

value. Therefore

DΔ

value not only can be used as a quantitative evaluation method for rubbed film

but as a process control method for stable orientation of liquid crystal.
