摘要: 根据Ericksen和Leslie的液晶弹性理论和动力学理论对共面转换液晶显示器件(IPS LCDs)响应时间参数进行分析,将手性平行排列引入这种模式,给出此种盒中的指向矢分布的动态方程.通过计算液晶盒中的瞬时指向矢分布,得到响应时间参数与扭曲角之间的关系.计算结果表明:具有一定扭曲角的手性沿面排列IPS模式的液晶盒将会有很高的响应速度.

关键词: 液晶显示器件, 响应时间, 扭曲角, 差分方法

Abstract: Based on Ericksen-Leslie's elastic theory and dynamic theory, the responsive time parameter of the in-plane switching liquid crystal displays is analyzed, the chiral-planar alignment is introduced into this mode, and the dynamic equation of the director is given. The relation of the responding time and the twist angle is obtained by calculating the instantaneous distribution of the director in this mode. The computational result demonstrates that there is a short responding time in IPS-Chiral-Planar liquid crystal cell with a certain twist angle.

Key words: liquid crystal display, the responding time, twist angle, diffenence method
