摘要

介绍了目前实现STN模式显示屏黑白化的主要方法。近年来ASTN迅速发展，ASTN体系的色散作为一个重要参数被提出，作为能否与TEP补偿膜相互匹配的依据。文章的主要工作是在一个母体液晶材料中，加入不同结构的化合物单体，灌注入液晶实验盒后，对其延迟量进行测试，并拟合出每种化合物单体在不同波长下的折射率各向异性，计算其色散。对不同结构单体与母体混合物在不同温度下的延迟量进行测试，并对比了各种化合物单体的色散随温度的变化趋势。对ASTN体系选择单体提供了化合物单体的色散依据，具有较重要的现实意义。

Abstract

The main techniques to realize black and white display for STN mode at present are introduced. With the rapid development of ASTN in recent years

the dispersion is proposed as an important parameter which decided the TEP compensation film of ASTV system can be matched or not. In this paper

the retardation were tested and the optical anisotropy were fitted in different wavelength to calculate the dispersion after different structure compounds were added in the same LC Host and then filled into the LC cells. The retardations of the mixtures of compound and LC Host under different temperature were tested also

and then the changing trends of different structure compounds dispersion were compared. The basic research on dispersion in this paper made great significant in selecting compound monomer of a ASTN system.
