Abstract
A device (300) to produce a color image using four or more primary colors. The device may include four or more transmissive spatial light modulators (309, 310, 311, 312) to modulate four or more, respective, light beams in accordance with four or more, respective, primary color image components of the color image to produce four or more, respective, modulated light beams. The device may also include a beam combining arrangement (320) to combine the four or more modulated light beams into a combined light beam carrying the color image.
