摘要： A liquid crystal projection system includes a light source module, a light management module, an image signal module and a projection lens. The light source module provides an illumination light beam of first polarization state. The light management module includes a color separator for separating the illumination light beam into a first color light beam and a bichromatic light beam, first and second reflectors for respectively reflecting the first color light beam and the bichromatic light beam, a phase plate for converting the polarization of the bichromatic light beam, a first PBS for receiving the first color light beam, a second PBS for receiving the bichromatic light beam, and a dichroic prism for separating the bichromatic light beam into second and third color light beams. The image signal module includes three image modulation units for transforming the polarizations of the first, second and third color light beams and modulating them into image light beams carrying corresponding image signals. The projection lens projects the first, second and third color light beams carrying corresponding image signals from the second PBS to a screen.

摘要： A liquid crystal projection system (70) includes a light source (50) for emitting a white light beam of three primary colors, a polarizer (51) for polarizing the white light beam, a separating mirror (52), first and second reflecting mirrors (53, 54), first and second polarization separators (56, 57), a half-wave plate (55), a color separator (58), image modulation devices (60R, 60G, 60B) and a projection lens (59). The separating mirror splits the incident polarized white light beam into two sets of polarized light beams, a monochromatic light beam and a bichromatic light beam that are respectively output to the first and second reflecting mirrors (53, 54). The polarized monochromatic light beam is reflected by the first reflecting mirror, transformed to a light beam with reversed polarization by the half-wave plate, and output to the first polarization separator. The polarized bichromatic light beam is reflected by the second reflecting mirror to the second polarization separator for polarization splitting, and then transmitted to the color separator for separating the two primary colors. The image modulation devices are arranged on sides of the first polarization separator and the color separator for respectively transforming and modulating the incident monochromatic and bichromatic light beams. The projection lens is disposed on one side of the second polarization separator.
