US 5,754,329 A · Electrochromic display laminates

Abstract

A laminate electrochromic display is disclosed in which a layer containing electrode leads addresses a laminate layer of side-by-side working and counter electrodes. A laminate layer of an electrochromic material is disposed on the electrode layer and, optionally, an ionically conductive electrolyte material is included in the electrochromic layer or provided in a separate electrolyte layer disposed over the electrochromic layer. In addition, a sandwich-type electrochromic device is disclosed in which the electrodes serve as either working or counter electrodes and a transparent electrode, disposed over the electrochromic layer serves as the other electrode. The electrochromic layer can optionally contain an ionically conductive electrolyte or, alternatively, a separate layer containing the electrolyte can be disposed between the electrochromic layer and counter electrode layer.

Dependent claims

A laminate electrochromic display comprising:

(a) a laminate layer of a nonconductive substrate material;
(b) a laminate layer containing a plurality of electrical leads disposed on said substrate layer wherein each electrical lead includes opposite ends and a central length extending therebetween and wherein an insulative material is disposed over the central lengths of said electrical leads;
(c) a laminate layer comprising side-by-side electrodes disposed on said electrical-lead layer including at least one counter electrode and a plurality of working electrodes wherein each electrode contacts an end of an electrical lead;
and
(d) a laminate layer comprising an electrochromic material disposed on said electrode layer;
wherein a portion of said electrode layer is isolated by said insulative material from the electrical lead layer extending thereunder.
