1. A display system, comprising:
- an optical transmitter configured to optically project digital image information associated with an image to be displayed; and
an active display including a decoder coupled with a plurality of display elements that are configured to produce visible light, where the decoder is configured to receive the projected 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 elements so as to cause display of the image;
where the active display includes a plurality of sub-arrays, each sub-array having at least one said decoder electrically coupled with a plurality of display elements that are configured to produce visible light, and where each decoder of each sub-array is configured to respond to a portion of the image information so as to cause the sub-array to display a portion of the image, such that the sub-arrays collectively display the image.

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.

12. An active display, comprising:
-
a plurality of spatially distinct display sub-arrays that are each configured to display a portion of an image, each sub-array including; a plurality of emissive components disposed on the sub-array and configured to produce visible light in response to electrical stimulation; and a decoder electrically coupled with the emissive components and configured to receive an optically transmitted serial bitstream of image information corresponding to the portion of the image to be displayed on the sub-array, the decoder being further configured to generate a plurality of control signals based on the serial bitstream, the control signals being adapted to control the emissive components so as to cause the emissive components to collectively display the portion of the image. - View Dependent Claims (13, 14, 15, 16, 17)

18. A display system, including:
-
an active display including a plurality of sub-arrays, each having; visible light-producing means for producing visible light in response to electrical stimulation; transmission means for optically transmitting image information associated with an image to be displayed in the form of spatially separated beams of light, individual of the beams of light corresponding to a one of the plurality of the sub-arrays and configured to be incident on the corresponding one of the plurality of the sub-arrays of the active display; and decoder means for optically receiving the beams of light and generating a plurality of control signals using the beams of light, the decoder means being coupled with the visible light-producing means and configured to apply the control signals to the visible-light producing means so as to cause display of at least a portion of the image. - View Dependent Claims (19)

20. A method of actively displaying an image, comprising:
-
optically projecting digital image information associated with an image to be displayed; optically receiving the projected digital image information at an active display device; processing the digital image information to generate a plurality of electrical control signals that each correspond to one of a plurality of individual emissive display elements provided on the active display device; and applying the electrical control signals to the emissive display elements to control visible light produced by the emissive display elements and thereby display the image; where optically transmitting digital image information includes optically transmitting a plurality of serial bitstreams, each of the bitstreams corresponding to a portion of the image to be displayed, and where each bitstream is optically received and processed at one of a plurality of spatially distinct display sub-arrays of the active display device. - View Dependent Claims (21)
