Patent ID: 7357555

Claim:
A display, comprising: an illumination system, wherein the illumination system comprises: a light source that emits light comprising a first optical characteristic; a light guide comprising an output surface, wherein the light guide is configured to direct at least a portion of the light emitted by the light source through the output surface of the light guide; emissive material positioned to receive light from the output surface of the light guide, wherein the emissive material emits light comprising a second optical characteristic when illuminated with light comprising the first optical characteristic; a first interference reflector positioned between the emissive material and the output surface of the light guide, wherein the first interference reflector substantially transmits light comprising the first optical characteristic and substantially reflects light comprising the second optical characteristic; and a spatial light modulator optically coupled to the illumination system, wherein the spatial light modulator comprises a plurality of controllable elements operable to modulate at least a portion of light from the illumination system.
