  • Patent number: 8514168
    Abstract: An electrophoretic display (EPD) with thermal control is disclosed for controlling and maintaining an image in extreme temperature environments. Techniques are also disclosed for maintaining the EPD cell threshold voltage for EPD cells comprising an EPD display media at or above a desired level in an environment in which the EPD may be subjected to an extreme temperature. The techniques comprise sensing a sensed temperature associated with the EPD display media, determining whether the sensed temperature satisfies a criterion established to ensure that the display media temperature remains at a level associated with an acceptable EPD cell threshold voltage, and in the event it is determined that the sensed temperature does not satisfy the criterion, controlling the EPD display media temperature as required to bring the sensed temperature to a level that satisfies the criterion.

    Abstract: Disclosed is an image display system for multi-viewing, including a display device for displaying right-eye images and left-eye images. A system controller is electrically connected to the display device and a light modulating device. A motion sensor, in response to a control signal from the system controller, is utilized for determining the positions of the eyes of a viewer. A processor, in response to one or more image signals from the motion sensor, provides the system controller with the positions. The light modulating device is utilized for spatially or angularly deflecting the right-eye images to the right eye of the viewer and for spatially or angularly deflecting the left-eye images to the left eye of the viewer in accordance with the positions.
