| Abstract: | This paper deals with the improvements in response time and reliability of the aWO3/LiClO4-PC (propylene carbonate) electrochromic display. Response time was improved by adopting the highly porous a-WO3 film, the porous reflector and the high surface area non-polarizable counter-electrode. Results from the reliability tests indicated that the ECD had a sufficient lifetime for practical applications such as in watches, clocks and calculators. The mechanism of performance drift upon cycling the display is investigated using ESCA, AES and atomic absorption methods. |
