Patent ID: 7188953

Claim:
A projection apparatus comprising: a) an illumination section comprising: i) a first light source for providing a first illumination beam; ii) a second light source for providing a second illumination beam; iii) a third light source for providing a third illumination beam; b) first, second, and third component wavelength modulating sections, each component wavelength modulating section accepting the corresponding first, second, or third wavelength illumination and modulating the corresponding wavelength illumination to provide a first, second, or third modulated component wavelength beam respectively, each component wavelength modulating section comprising: i) a portion of a monochrome transmissive liquid crystal modulator panel that has been segmented into at least a first portion, a second portion, and a third portion, and wherein each portion is spatially separated from each other portion; ii) a component wavelength polarizer in the path of the component wavelength illumination for directing substantially polarized light to the corresponding portion of the monochrome transmissive liquid crystal modulator panel; iii) an illumination path Fresnel lens for focusing incident illumination from the component wavelength polarizer through the corresponding portion of the monochrome transmissive liquid crystal modulator panel; iv) an analyzer for conditioning the polarization of the modulated component wavelength beam; v) a lens for forming an image for projection onto a display surface; and whereby the image formed on the display surface comprises a plurality of superimposed component wavelength beams.
