Abstract
There is disclosed an electrochromic passive-matrix display, wherein each passively addressed pixel cell comprises an electrolyte ionically connecting an electrochromic and electrochemically active polymer and a layer of electrically conducting carbon. Thus, each pixel has a pronounced threshold voltage sufficient for reducing cross talk in an electrochromic display.
