Measurement of polar anchoring strength and analysis of the mechanism of surface liquid crystal alignment

考虑均匀对准LC电池中多个干扰的入射角依赖性，设计了一种简单、高精度的液晶分子对准分布和表面极性锚定强度测量方法。测量了定向层表面极性锚固强度对温度的依赖关系，明确了定向层表面极性锚固强度与LC吸收层之间的关系。

A simple and highly accurate measurement method was devised for the alignment distribution of liquid crystal molecule and surface polar anchoring strength by considering the incident angle dependence of multiple interferences in the homogeneous alignment LC cell. We measured the temperature dependence of the polar anchoring strength on the surface of alignment layers and clarified that the there is a relation between the polar anchoring strength and the LC absorption layer on the surface of alignment layers.
