<p>ELECTROCHROMIC DISPLAY ELEMENT AND PROCESS of the Invention An electrochromic display for selectively displaying optical patterns comprising a sandwich type structure which includes transparent front electrodes, electrochromic layers on the front electrodes, an electrolyte and a special electroreactive layer on a rear electrode. The electroreactive layer, which serves as hydrogen source, is composed of electrochromic material which is first oxidized and subsequently heat treated in a hydrogen or forming gas atmosphere to improve the operating and life characteristics of the display. The electrodes are mounted or deposited respectively on parallel substrates which form the outer structures of a hermetically sealed display arrangement. The electroreactive layer can be a single layer structure serving the functions of both the rear electrode and hydrogen source material.</p> |
