Coloured electrochromic "paper-quality" displays based on modified mesoporous electrodes

Progress on the development and commercialisation of electrochromic displays that have comparable optical qualities to paper-based display media relies on several factors. The electronic display must meet key requirements of paper-based media in readability, switching speed, power consumption, and stability to seriously be considered as a replacement. In addition, broadening of the colour range of electrochromic pixels is a factor that is compelling to the commercial uptake and usage of electrochromic "paper-quality" displays. We report the progress that has been made in increasing the colour range and in assessing the lifetime of clectrochromic displays based on modified mesoporous electrodes. (C) 2003 Elsevier B.V.
