摘要：

Solid-state electrochromic display devices (ECDs) have been prepared using vacuum deposited tungstic oxide as the primary electrochromic material. Such devices form colour during irradiation from a fluorescent-tube as light source. Initial experiments incorporated (evaporated) CdS films and the proton-conducting poly(ethylene oxide)-phosphoric acid electrolyte (1:1) plasticised with acetonitrile. Successful photoelectrochromic devices were prepared in this way provided the electrolyte was anhydrous, since films of CdS are sensitive to water-attack. Another device to evince photoelectrochromism was one containing layers of WO3 and V2O5. This combination of oxides was the most promising responding to a 1/20s flash of intense white light. As yet, the colour formed in this way cannot be electro-bleached. These displays may also be used as normal-electrolytically driven-devices in the absence of irradiation.
