Optical Design for Reflective Dual Operation Liquid Crystal Display

摘要

We propose a reflective dual operation liquid crystal display (LCD) that can be operated in memory mode as well as dynamic mode. It consists of a polarizer, an optical compensation film, a LC layer and a reflector. The optical parameters are optimized by Jones matrix method. As a result, our reflective dual mode LCD has contrast ratio of over 300:1 in both memory and dynamic modes due to a completely dark state over the entire visible-wavelength range.
