P‐197: Improved Patterned VA Mode for Fast Response Time by Using Strong Fringe‐Field Effect

Abstract

We propose an improved pattern structure that can reduce the response time by using strong fringe field in the pattern vertical alignment LCD. We applied an additional buried electrode in the PVA LCD so that we could increase the fringe field on the edge of the electrode. The strong fringe field on the edge of the electrode helps the liquid crystal director in the bulk area to have an appropriate orientation quickly when the voltage is applied. As a result, we could improve the response time effectively. We used the software TechWiz LCD in order to calculate the director configuration and the response time. From the simulation results, we have found that the proposed structure exhibited 74.2% improvement in response time compared to the conventional structure in calculation.
