Claim Text:
1. A display system, comprising an emissive body, divided into sections including at least first and second sections, and emitting light from at least one surface, said emissive body receiving a color temperature control from a frequency generator that controls multiple different color temperatures of said light, where each of the sections has their color temperature separately controlled by said color temperature control, and where a first section of the emissive body is controlled to output a first color temperature of light, and a second section of the emissive body, different than the first section of the emissive body, is controlled to output a second color temperature of light, different than said first color temperature of light; and a spatial light modulator, having multiple individual controllable pixels, said multiple pixels being illuminated by said emissive body, and said pixels each modulating the light from said emissive body to produce a display, where said first and second sections of said emissive body illuminate the spatial light modulator with different color temperatures in different areas including at least said first color temperature in said first section and said second color temperature in said second section, wherein the frequency generator driving said emissive body, to emit light at said multiple different color temperatures by changing a frequency emitted by the frequency generator, where the frequency of the frequency generator changes a white balance of its light output.
