The present invention is a reversible electrodeposition optical modulation
device employing a segmented counter electrode that permits localized
areas of a continuous optical modulation electrode to be switched
independently of each other. Such devices can be configured to enable
practically seamless switching over the entire device for smart window and
adjustable mirror applications, or to minimize cross-talk and pixel
overlap for display applications. Since the electrical contacts and
switching circuitry are located on the counter electrode, more active area
is available for optical modulation.
