Abstract
An improved working electrode for use in display devices is disclosed. The working electrode comprises a transparent metal grid having a coating of metal oxide thereon. Suitable metal grids include Cu, Au, Ag, Al, Pt, Ni and Zn, while suitable metal oxide coatings include In2 O3, SnO2 and indium tin oxide (ITO). The display devices preferably include an electrochromic material comprising an aqueous solution of an electrochemically depositable metal. Display devices in which the present working electrode is used possess favorable characteristics such as rapid response times, wide dynamic range, high transmittance and improved uniformity. The devices are particularly suitable for large surface area applications.
