Design of Reflector with Rough Surface for Reflective Type Color LCD

Abstract

A novel way developed to estimate and design a reflector for reflective color LCDs which is based on the discovery that the shape of surface bumps on the reflector is actually a concurrence of multiple micro flat mirrors. Scattering of the reflector was calculated from the slope angle distribution of these micro-flat mirrors. This enabled us to determine the ideal bump shape for reflective color LCDs. Accuracy was confirmed by analyzing actual reflectors, and a nearly ideal reflector was fabricated by optimizing bump shape.
