Abstract

Embodiments of the present invention provide a method, apparatus and system of producing a color image using four or more primary colors. The apparatus, according to some demonstrative embodiments of the invention, may include four or more transmissive spatial light modulators to modulate four or more, respective, primary color 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; and a beam combiner to combine the four or more modulated light beams into a combined light beam carrying the color image. The beam combiner may include, for example, an X-cube to jointly direct three of the four or more modulated light beams; and a selective color rotator to rotate the polarization of two of the three modulated light beams, while maintaining the polarization of a third one of the three modulated light beams. Other embodiments are described and claimed.
