扭曲向列相效应透过特性的理论分析

THE THEORETICAL ANALYSIS OF THE TWISTED NEMATIC TRANSMISSIVITY

本文利用琼断矩阵理论,推导出扭曲角在0°～90°之间、线性扭曲向列相效应的透过率表达式。它能够比较好地解释ECB效应、TN效应和扭曲角φ∈(0,90°)三种效应之间的关系。

In this paper, using Johnes matrix theory, leads to a transmissivity expression of the twisted angle from 0° to 90°and the linear twisted nematic. It clearly explains the relation of the three effects:the ECB effect, the TN effect and the twist angleψ∈(0°,90°).
