Paper Abstract

Polymer electrolyte - based display devices are of growing importance in view of their specific properties compared to liquid devices. One of them is, of course, the possibility to obtain all solid-state devices without leakage and another one, may be more interesting, is the possibility to obtain a strong dependence of the response time of the display on the temperature. Such a property may be conveniently used for the realization of devices with specific applications such as thermal sensors or heated display devices, for instance. The optical response characteristics of amorphous W03/polymeric electrolyte/stainless steel electrochromic display (ECD) devices have been investigated using cyclic voltammetry and chronoamperometry coupled with optical reflection measurements. The variations of both the colouration time and the colouring efficency with temperature are related to both the ionic conductivity of the polymer and the phase diagram of the polymer.
