PROJECTION APPARATUS USING LCD PANEL |
摘要 |
A projection apparatus (10) has an illumination section (68) that provides at least a first, a second, and a third component wavelength illumination. At least two component wavelength modulating sections accept and modulate the component wavelength illumination to provide a modulated component wavelength beam. Each component wavelength modulating section has a portion of a monochrome transmissive liquid crystal modulator panel (118) that has been segmented into at least a first, a second, and a third spatially separate portion. A component wavelength polarizer directs substantially polarized light to the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An illumination path Fresnel lens focuses incident illumination from the component wavelength polarizer through the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An analyzer conditions the polarization of the modulated component wavelength beam. A lens forms an image of superimposed component wavelength beams for projection onto a display surface (40). |
