Abstract:
A projector comprising:a light source for emitting a beam of light; a color wheel for splitting two, or more than two color beams from the beam of light; a rod lens for making a distribution of the color beam from the color wheel uniform; a polarization beam converter for converting the color beam from the rod lens into a particular polarization beam; an optical part for focusing the color beam converted into the particular polarization beam; a color selecting plate for receiving the color beam from the optical part and converting a particular polarization color beam in the color beam; a polarization beam sprite prism for forwarding a particular color beam having polarization converted at the color selecting plate, and color beams of other colors through different paths; a first display for reflecting the particular color beam from the polarization beam sprite prism according to a video signal, to produce a picture beam; a second display for reflecting the color beams of other colors than the particular color beam from the polarization beam sprite prism according to a video signal, to produce a picture beam; and, a projection lens for enlarging, and projecting the picture beams.
