Optical design of R-OCB Mode Full-color Reflective LCD with Wide viewing angle and High contrast

Abstract

One polarizer type reflective LCDs are promising to use in reflective color LCDs with high resolution and gray scale and moving image capability. However, in order to apply it to high-quality monitor displays, its contrast ratio is not sufficiently high in wide range of wavelength and viewing angle. In this paper, we discuss the design rule of liquid crystal layer and retardation films for the one polarizer type reflective LCDs to get high quality, especially high contrast ratio, for the monitor displays.
