Abstract:
A new broadband wide-view circular polarizer is proposed for high transmittance multi-domain vertical-alignment liquid crystal displays (MVA LCDs). This configuration only requires one biaxial plate in the conventional circular polarizer. The optimal film parameters are obtained analytically through spherical trigonometric method on the Poincaré sphere and through computer-aided parameter search method. According to this design, the high transmittance MVA LCD exhibits a contrast ratio CR 200:1 over approximately 80 degrees viewing cone.
