Patent Number: 6736514 
Title: Imaging Apparatus for Increased Color Gamut Using Dual Spatial Light Modulators 
Abstract: A display apparatus (10) for projection of a color image from digital data onto a surface (140) comprises a first modulation system which provides a first modulated beam. The first modulation system comprises a first spatial light modulator for modulating a first incident light beam in order to form the first modulated beam according to the digital data; a first light source provides a first color beam as the first incident light beam; and a second light source provides a second color beam as the first incident light beam. A second modulation system provides a second modulated beam. The second modulation system comprises a second spatial light modulator for modulating a second incident light beam in order to form the second modulated beam according to the digital data; a third light source provides a third color beam as the second incident light beam; and a fourth light source provides a fourth color beam as the second incident light beam. An optical combiner (30) directs the first modulated beam and the second modulated beam for projection onto the surface by a projection lens.
