OCB模式液晶显示器件响应时间研究

摘要

On the basis of discussing the importance of fast response techniques in Liquid Crystal Display ( LCDs) , Factors influencing response time by differential equation of liquid crystal molecules motion un-der external electric field was studied. Combining with velocity gradient figure,the dynamic curve of direc-tor from the mutual reaction between drainage and molecule's motion under external field based on the liquid crystal Optical Compensation Bend (OCB) mode was explained. Subsequently, the best driving wave from the viewpoint of energy was reviewee. A new mode design based on nucleus' contribution, with 7% improvement in response time compared to OCB mode,is suggested.%文中在讨论响应时间对液晶显示的重要意义的基础上,从分子外场运动微分方程入手解析了响应时间的影响因素,重点研究了光学补偿弯曲模式(OCB)液晶盒的快速响应原理.从引流与分子外场下运动相互作用入手,结合流速梯度变化描述了指向矢动态衍生过程,并从能量角度讨论液晶盒最佳驱动波形.最后基于成核中心对快速响应的贡献给出一种新型初态设计,经验证,其响应速度较传统OCB模式提升7％.
