Abstract:
A projection display apparatus comprising:a light source adapted to provide a light beam; a wide angle reflecting polarizer adapted to pass substantially all light of a first polarization component of the light beam, and to reflect substantially all light of a second polarization component of the light beam; and an image engine adapted to receive one of the first or second polarization components and to return to said wide angle reflecting polarizer a polarized image in which polarization of the one of the first or second polarization components is shifted corresponding to an image to display to include portions of the second or first polarization components, wherein the image engine further includes a prism for splitting rays of polarized light received from the reflecting polarizer into the first and second color band, wherein the first color band is passed through a color wheel/shutter to a single LCD for color sequential operation, and wherein the second color band is passed to a second LCD.
