  • Electrochromic device based on nanocrystalline materials
    Patent number: 7508009
    Abstract: An electrochromic device, comprising a first electrode (3), a second electrode (5) and an electrolyte (4) separating the electrodes (3, 5), where at least one of said first and second electrodes includes an electrically active structure which have an at least dual state visual appearance depending on the potential difference between the first and the second electrode.
    Type: Grant
    Filed: August 2, 2001
    Date of Patent: March 24, 2009
    Assignee: Ntera, Ltd.
    Inventors: Marten Edwards, Anders Hagfeldt, Gerrit Boschloo, Sten-Erik Lindqvist
  • Method of controlling an electrochromic matrix display and electrochromic display
    Patent number: 7453435
    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.
