ABSTRACT:
An electrochromic imaging apparatus utilizing electrochromic iridium oxide and a thin-film solid ionic conductor. In a transmissive cell, a first electrode, a photoconductive material layer, an electrochromic iridium oxide layer, an ionic conductive material layer and a second electrode are successively disposed on a substrate. The electrochromic iridium oxide exhibits coloration when an electric field of one polarity is applied across the first and second electrodes to record an image which is incident upon the substrate. Reversal of the polarity of the electric field across the first and second electrode causes bleaching of the electrochromic iridium oxide. In a reflective cell, a light blocking layer having a reflective surface is disposed between the photoconductive material layer and the electrochromic iridium oxide to optically separate a viewing light incident upon the second electrode from the image incident on the substrate. In a reflective cell having two separate memories, an electrically insulating, optically transparent material layer is interposed between a transmissive cell and a reflective cell. A light source projects the image formed in the electrochromic iridium oxide layer in the transmissive cell through the electrically insulating layer to the reflective cell in which the image is formed in the second electrochromic material layer. The image on the second electrochromic material layer is viewed independently from the image in the first transmissive cell.
