| 摘要 |
An electrochromic display device having transparent front electrodes on a substrate, said front electrodes being coated with electrochromic material having different oxidation states for displaying optical patterns, a back electrode on a parallel substrate also coated with electrochromic material, a thin porous separator between the substrates, a liquid electrolyte contacting the electrochromic layers, said electrolyte being saturated with electrochromic materials in each of the oxidation states to reduce the degradation of the electrochromic layers as they pass through each of the oxidation states. The saturating materials are tungsten trioxide, hydrogen tungsten oxide, and tungsten dioxide in the electrochromic display described.
