Wide Viewing Angle HAN-LCDs using Optical Compensation Films

Abstract

Hybrid-aligned nematic liquid crystal displays (HAN-LCDs) are known to have the device peformance of fast response speed and low driving voltage. In this paper, we have tried to improve the viewing angle characteristics of HAN-LCDs by using optical compensation films. The study is performed by doing computer simulation of the device. The result show that the use of optical compensation films for widering the viewing angle performace is very successful to keep a wide viewing range of the black level and thus, the good viewing angle characteristics is obtained.
