Ceramics for electrochromic display

摘要

An electrochromic display comprising a display electrode and a counter electrode which form a cavity therebetween like a sandwich, the former consisting of a transparent conductive coating and a layer of transition metal oxide which varies reversibly in the light absorption spectrum upon application of current and the latter consisting of a conductive coating and a reversible charge exchange system. An electrolyte is injected into the cavity. A porous ceramics plate is positioned in contact with the display electrode and the counter electrode. This application is a continuation of copending application Ser. No. 760,521, filed on Jan. 19, 1977, now abandoned.
