Electrochromic System Toward Color Electronic Paper

Abstract

The demand for global environmental conservation and decrease of CO₂ evolution as well as for a portable display with light-weight and low-power consumption require the development of “new imaging media”, instead of paper. This display is categorized as reflective display and is called “electronic paper”. Many technologies are proposed to fabricate reflective display, but microcapsulated electrophoretic system is the leading technology at present. Electrochromic system in which the color change is induced by electrochemical reaction is also a potential candidate to realize color reflective this play. In this paper, the material as the color material for electrochromism and its application for display are reviewed. Further, new electronic paper system are also commented upon.
