ABSTRACT:
Electrochromic matrix and method of controlling the grey state of pixels in an electrochromic matrix display comprising a first set of electrodes being formed of electrically isolated conduction lines, a second set of electrodes being formed of electrically isolated conduction lines, an electrochromic material and an electrolyte being arranged between or on said first and second sets of electrodes and drive means arranged to supply drive voltages selectively to individual electrodes in said first and second sets of electrodes, said first and second sets of electrodes being arranged in a pattern such that each electrode in said first set intersect each electrode in said second set at a single location and such that electrode in said second set intersect each electrode in said first set at a single location, said intersections between the first and second sets of electrodes forming a set of pixels.
