Abstract
A device comprising a clear substrate (24) supporting at least one thin, clear, electronically conductive work electrode (23); a substrate (5, 3) supporting at least one electronically conductive counter electrode (2); at least one intermediate layer (25,26) providing electrochromism; and a means for supplying current to the ends of the electrodes (23) and counter electrodes (23) and counter electrodes (2), optionally combined with a means for supplying current into said clear electrodes (23) and/or counter electrodes. An array of counter electrodes configured in fine lines and/or an additional current supplying means may be formed by means of a fabric, lap or grid assembly of conductive (2) and non-conductive (3) wires (3) being arranged with respect to wire (2) in such a way that the latter are kept apart, and/or that the strength of the assembly is promoted.
