1. An optically addressable display comprising:
- a projection device including,a mechanism to create emissions having plural polarizations, wherein the number of polarizations defines a corresponding number of color channels; and
a data encoder to apply data for each of the color channels to the emissions having corresponding ones of the plural polarizations; and
a screen including,a plurality of pixels for producing a color display; and
a plurality of receptors including at least one receptor for each of said plurality of pixels responsive to a corresponding polarization state for each of the color channels, said plurality of receptors activating said pixels using a corresponding color channel depending upon which, if any, of the emissions having a corresponding polarization state for said corresponding color channel is received.

Abstract
An optically addressable display of a preferred embodiment uses emissions having plural polarizations to define a corresponding number of color channels. A data encoder applies data for each of the color channels to corresponding ones of the plural polarizations. The display also includes plurality of pixels for producing a color display. There is a plurality of receptors including at least one receptor for each pixel. The receptors activate pixels depending upon which, if any, of the plural polarizations is received.

25. A method of encoding color data to activate an optically addressable display including a plurality of pixels, the method comprising the steps of:
-
at a projection device; producing emissions having different polarizations; for each pixel, applying data to each of said emissions having different polarizations by selectively passing said emissions having different polarizations to said pixels; at the optically addressable display; at each pixel, responding to each of said emissions having different polarizations with a corresponding receptor; and producing a different display for each of said emissions having different polarizations when responded to by the corresponding receptor. - View Dependent Claims (26, 27, 28, 29, 30, 34)
