Abstract:
A color display system in which image data is converted into red, green and blue data prior to display, and displayed on a display system having at least one spatial light modulator, comprising:a) a processing element which derives white image data from said red, green and blue data; b) a source of red, green, blue and white light operable to impinge light on the spatial light modulator; c) a system controller for controlling the timing of the red, green, blue, and white data onto the spatial light modulator, such that the appropriate data for each color is present when that color light is striking the spatial light modulator; and d) a nonvolatile memory for storing correction data which corrects for differences between the white image data and the light from the source, allowing the display system to add brightness to the display system and preventing artifacts.
