Abstract: MATRIX ADDRESSED ELECTROCHROMIC DISPLAY A matrix addressed electrochromic display includes first and second spaced apart opposed planar panels, a dielectric spacer peripherally sealing the panels to provide an interior cavity therebetween to define a display region, an electrochromic fluid filling the interior cavity, a plurality of parallel rows and columns of electrodes disposed in the mating surfaces of the first and second panels respectively and a low output impedance electrical refresh circuit coupled to electrically energize the electrodes in a repetitive matrix selection pattern to provide a selected dot matrix display.
