Light is shined on an addressable spatial light modulator, and the light is also integrated. The data displayed on the spatial light modulator is changed when the integrated light reaches a predetermined value. The light may impinge on the spatial light modulator through a color wheel, which may be rotated faster than the frame repetition rate of video information that is being displayed. Alternatively, the light may be generated by different-colored lamps. The intensity of the light may be controlled in accordance with the bit rank or significance of the bits that are being displayed by the spatial light modulator. Several techniques for achieving different intensity levels are disclosed.
