Patent ID: 7621641

Claim:
A projection apparatus comprising: a) an LC modulator panel, 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, the LC modulator panel comprising a photoresponsive layer; b) an image-writing section for forming a first image within the first portion, a second image within the second portion and a third image within the third portion of the LC modulator panel by scanning successive lines of image-writing light to energize the photoresponsive layer thereby, the image writing section comprising: (i) at least one narrow band light source for emitting a narrow band light; (ii) at least one grating electromechanical system for modulating the narrow band light to provide modulated light in diffracted and non-diffracted orders; (iii) a selecting element for blocking at least one order of the modulated light to provide a scanning light; (iv) a scanning element for directing the scanning light toward the LC modulator panel to energize the photoresponsive layer; c) an illumination section for directing first, second, and third illumination beams for modulation by the respective portions of the LC modulator panel; d) a polarizing beamsplitter associated with each of the first, second, and third portions for providing first, second, and third polarized illumination beams, for directing the first, second, and third polarized illumination beams toward the LC modulator panel and for directing modulated light from the LC modulator panel toward a lens for projection toward a display surface; and e) a separate polarizing beamsplitter associated with each of the first, second, and third portions.
