A supported or self-supporting electrochromic device is provided having (a) at least one electrochromic element comprising (i) at least one material that is electrically conducting in at least one material that is electrically conducting in at least one oxidation state and (ii) at least one electrochromic material, wherein said materials (i) and (ii) can be the same or different, (b) at least one layer of a solidified electrolyte which is in direct electrical contact with said electrochromic element, and (c) at least two electrodes adapted to be electrically connected to a voltage supply so as to create a difference in potential therebetween, with each of said electrodes being in direct electrical contact with at least one of said electrolyte layer(s) and not in direct electrical contact with said electrochromic element. Displays incorporating such a device, as well as processes for the production of such a device are contemplated. A method for addressing an electrochemically active element also is provided.
A supported or self-supporting electrochromic device comprising:
A process for the manufacture of a supported electrochromic device comprising:
A method for the application of an electric voltage to an electrochemically active element in direct electrical contact with an electrolyte, wherein electrodes of a voltage supply are brought into direct electrical contact with the electrolyte only, so as to generate an electric field in the electrolyte, which electric field in turn gives rise to a voltage induced within the electrochemically active element through its interface with the electrolyte.
