Abstract

The conditions for the emergence of a fast electro-optical mode in a liquid crystal cell with a short period (p = 1.8 μm) of interdigitated electrodes have been investigated. The electro-optical switching in two liquid crystal mixtures differing in viscosity and dielectric and optical anisotropies has been studied through numerical simulations and experimentally. The fast mode switching times are shown to be in the submillisecond range and to be related to the switching of a near-electrode liquid crystal layer comparable in thickness to the period of the electrode structures. The inclusion of the entire liquid crystal volume in the switching process is characterized by a slow mode with considerably longer times.

具有叉指电极的液晶单元的电光转换中的快速模式

摘要

已经研究了在具有短周期（p = 1.8μm）叉指电极的液晶盒中出现快速电光模式的条件。通过数值模拟和实验研究了两种粘度和介电常数及光学各向异性不同的液晶混合物中的电光转换。快速模式切换时间显示为在亚毫秒范围内，并且与厚度与电极结构的周期相当的近电极液晶层的切换有关。在切换过程中包括整个液晶体积的特征在于具有较长时间的慢速模式。
