1. A display system comprising:

  • a spatial light modulator for displaying an output color image formed from input image color data;

    the spatial light modulator substantially comprising a subpixel repeating group including subpixels in a plurality of primary colors;

    a plurality of individually addressable colored light emitters disposed as a backlight to provide light for forming the output color image on the spatial light modulator;

    each light emitter producing light in one of a plurality of colors; and

    controller circuitry for controlling light from the plurality of individually addressable colored light emitters;

    the controller circuitry using the input image color data to determine a value for each of the individually addressable colored light emitters such that an output image color in one of the subpixels of the spatial light modulator depends on the color of the light from the light emitters.
