Abstract:
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 a first subpixel configured to transmit a light having a first primary color, a second subpixel configured to transmit a light having a second primary color, a third subpixel configured to transmit a light having a third primary color, and a clear subpixel configured to selectively transmit a light substantially having one of the first to third primary colors, the first to third primary colors being different from each other; 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 configured to produce light substantially having one of the first to third primary colors; and a controller circuitry for controlling light from the plurality of individually addressable colored light emitters, the controller circuitry configured to use 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, wherein the controller circuitry is configured to control the spatial light modulator and the light emitters such that the clear subpixel selectively transmits the light having one of the first to third primary colors as desired.
