High-precision Measurement of the Threshold Voltage, the Elastic Constants Ratio and the Dielectric Constants Ratio of Liquid Crystal Materials

Abstract

We devised a high-precision method of measuring the threshold voltage and the elastic and dielectric constants ratios of liquid crystal materials. We obtained these parameters from measuring the alignment distribution of homogeneous alignment LC cell in the on state. We confirmed the validly of this method through measurements of several LC cells with different gaps.
