  • Patent number: 7808446
    Abstract: A display system, including an optical transmitter configured to optically transmit digital image information associated with an image to be displayed. The system also includes an active display including a decoder electrically coupled with a plurality of display elements that are configured to produce visible light in response to electrical stimulation. The decoder is configured to receive the digital image information and in response produce a control signal for each of the display elements, the control signals being usable to individually control visible light produced by the display elements so as to cause display of the image.
    Type: Grant

  • Patent number: 7079154
    Abstract: A sub-pixel assembly of one embodiment of the invention is disclosed that includes a number of active display units. Each active display unit is capable of controlling light, and has a turn-on threshold responsive to a signal. The active display units are organized by their turn-on thresholds to achieve dithering of the light, in response to the signal.

  • Patent number: 7057583
    Abstract: A display system including a projector and a display. The projector is adapted to wirelessly transmit image information associated with an image to be displayed. The display includes a plurality of display cells that are configured to collectively display the image based on the image information transmitted by the projector. Each display cell includes a receiver, display element and storage device. The receiver is configured to wirelessly receive a portion of the image information, and the storage device is adapted to store a control signal corresponding to the received portion of the image information. The display element is configured to display the corresponding portion of the image in response to application of the control signal from the storage device.
