To reduce the residual direct-current (DC) voltage in liquid-crystal display (LCD) using the polymer-stabilized vertical-alignment (PS-VA) mode, the electrical time constant of two or more serially connected dielectric materials, such as liquid cryst

The properties such as cell gap, pretilt angle and rubbing direction in the multi domain PS(polymer stabilized)-VA cell were measured by a optical method. It has been impossible to measure the pretilt angle in sub micrometer area because liquid cryst

We designed a novel mountain-shaped cell architecture in order to obtain less than 15 ms of tr+tf response time without an overdriving circuit in vertical alignment mode. This structure significantly reduces the tr+tf time of PVA mode by eliminating
