一种宽视角和快速响应的连续视角可控液晶显示
Continuous viewing angle controllable liquid crystal display with wide viewing angle and fast response
摘要
Abstract
Vertical alignment liquid crystal display mode has good dark state,so that it has high con-trast ratio.However,it’s viewing angle is not good.The viewing angle can be improved by using multi-domain vertical alignment (MVA ) and patterned electrode vertical alignment (PVA ). However,the protrusion in MVA may lead to light leakage because of the small tilt angle in the initial state,which reduces the contrast ratio.While the light leakage is removed in PVA because the pro-trusion is replaced by the patterned electrode,the trade-off is slower response speed.In this paper, we proposed a new vertical alignment liquid crystal display device with four etched cambered hollows at the edges of the pixel electrode and a circular hole at the centre of the common electrode.The liquid crystal molecules fall down to the centre of the substrate when the operating voltage is applied,as a result,the centro-symmetric structure leads to the wide viewing angle and uniform contrast ratio.Moreover,this struc-ture can improve the response speed and has a high transmittance.In addition,the continuous change of vie-wing angle controlled by bias voltages on common electrode can be obtained.关键词
