Abstract: The present invention provides a polarized colored light source for a display system in which light of other polarization states and colors are recycled. The color can be scrolled synchronously with a display. In one embodiment, the invention includes a tunnel having an entrance aperture facing a lamp to receive light having multiple polarization states from the lamp and direct the light from the lamp to an exit aperture opposite the entrance aperture, the tunnel having a reflective face about the entrance aperture to reflect light within the tunnel toward the exit aperture, a reflective polarizer to reflect light of one polarization state toward the entrance aperture and transmit light of another polarization state, and a color reflector to transmit light within one color range and reflect light of another color range toward the entrance aperture.

Abstract: An apparatus, system, and method for a polarizing conversion assembly adapted to provide polarized light having an intensity distribution to complement an angular transmission distribution of a corresponding light modulator are disclosed herein.

Abstract: A rear projection display system is disclosed. The display system includes an image source for projecting an image, a rear reflector, and a screen configured to display the projected image. The screen includes a plurality of reflective elements configured to angularly discriminate light without regard to polarity by reflecting light incident on the screen from a first angle toward the rear reflector, and to allow light incident on the screen from a second angle to be transmitted through the screen for display.

Abstract: A polarized light source for a display system includes an optical system to image light from a light source onto a display along a first optical path, a reflective polarizer to receive the light from the optical system along a first optical path, direct light of a first polarization of the display, and reflect light of a second polarization along a second optical path separate from the first optical path toward the optical system, a mirror in the second optical path to receive light having the second polarization from the reflective polarizer, and reflect it back to the reflective polarizer, and a polarization conversion system in the second optical path between the reflective polarizer and the mirror to convert the polarization of the reflected light of the second polarization to the first polarization.

Abstract: A multimedia projector (100) includes a single-path frame-sequential color optical system in which light rays emitted by a light source (14) propagate through a color wheel (102) and an optical integrator (16, 120, 122), and are directed toward a transflective polarizing beam splitter (40) that separates them into P-polarized components (76) and S-polarized components (78). The P-polarized components are transmitted toward a reflective LCD (26) in which pixels in a dark state reflect the light rays without a polarization change and return them through the transflective polarizing beam splitter, whereas pixels in a bright state reflect the light rays with a 90° polarization change as S-polarized light rays (112), which are reflected by the transflective polarizing beam splitter toward a projection lens (27).
