Multi-color electrochromic cells having solid polymer electrolytes and a distinct electrochromic layer
First Claim
1. A solid-state multi-color electrochromic display cell comprising an electrochromic half cell, a counter half cell, and a separator therebetween, said electrochromic half cell comprising a display electrode comprising an electronically conducting film on a substantially transparent plate and a distinct electrochromic layer consisting essentially of an organic electrochromic chemical having one side immediately adjacent said electronically conducting film and further comprising a solid electrolyte layer comprising an ionically conducting polymer and a supporting electrolyte between said electrochromic layer and said separator, said separator comprising an insoluble cation conducting membrane and said counter half cell comprising an ionically conducting polymer layer with supporting electrolyte immediately adjacent said separator, a redox electroactive chemical and a counter electrode.
