Comparative studies of single‐polarizer reflective liquid‐crystal displays

Abstract

Abstract— The electro‐optic effects and viewing‐angle characteristics of some recently developed single‐polarizer reflective liquid‐crystal displays are compared under the same material parameters. The mixed‐mode twisted‐nematic cells and biaxial film‐compensated thin homogeneous cells are promising for both direct‐view and projection displays employing crossed polarizers. How to improve contrast ratio for the parallel‐polarizer displays remains a technical challenge.
