摘要/Abstract

摘要： 基于液晶弹性理论研究了电压作用下向列相液晶盒中的挠曲电体积效应.通过变分理论得到了液晶指向矢倾角θ满足的微分方程,利用差分迭代的目的计算了强锚定平行排列液晶盒和混合排列液晶盒中液晶指向矢的分布情况,利用琼斯矩阵的目的计算了两种液晶盒中电光特性曲线.结合计算结果分析了挠曲电体积效应对混合排列液晶盒中液晶指向矢分布及电光特性曲线的影响.

关键词: 挠曲电体积效应, 变分理论, 琼斯矩阵方法, 电光特性曲线

Abstract: With elastic theory of liquid crystal,we investigate bulk flexoelectric effect in a nematic liquid crystal(NLC) cell with applied voltage.The differential equation of director tilt angle θ is obtained by the variation theory. The distributions of director in a strong anchoring planar aligned cell and in a hybrid aligned nematic(HAN) cell are calculated. The transmittance characteristic of these liquid crystal cells is obtained with Jones matrix method.Influence of bulk flexoelectric effect on the distribution of director and characteristic transmittance of liquid crystal cells are analyzed.

Key words: bulk flexoelectric effect, variation theory, Jones matrix method, transmittance characteristic
