  • Publication number: 20110157483
    Abstract: A projector for projecting diffracted light in a selectable pattern and/or animation on a display surface. The apparatus includes a light source providing one or more beams of coherent light from one or more lasers. The apparatus includes a diffraction assembly in the path of the light source to generate diffracted light by diffracting the laser light with one, two, or more diffraction grating patterns and, optionally, with a diffraction glass or other material. An active mask is provided with a raster that receives the diffracted light and that includes a plurality of optical shutter elements that are selectively operable to project a portion of the diffracted light from the active mask toward the display surface. In one example, the active mask includes a liquid crystal display panel to provide a grid of addressable programmable pixels that are turned on and off to project portions of the diffracted light.

  • Publication number: 20090185083
    Abstract: A display device displays a D-seat image and a P-seat image on a display screen in a time-sharing manner, and forms a non-display state by inserting a black image BL or the like when changing the viewing angle of the display screen by controlling a liquid crystal shutter provided on the display screen in synchronization with the switching between the D-seat image and the P-seat image. With this display device, it is possible to prevent the image in one field of view from entering the other field of view, even if there are differences in the switching timing of the liquid crystal shutter.

  • Publication number: 20080246891
    Abstract: In display systems employing spatial light modulators, the OFF-state light from OFF-state pixels of the spatial light modulator can be captured and directed back to the pixels of the spatial light modulator so as to recycle the OFF-state light in the display system. Bitplanes derived from the desired image to be produced are calibrated to include the recycled off-state light to properly produce the desired image using the display system.

  • Patent number: 6827451
    Abstract: An apparatus is disclosed comprising a lamp which produces a first light which may be a white light; a first light valve, a second light valve, a first color separator, and a first aperture device. The first color separator receives the white light from the lamp, and separates the white light into a first color light and a first residual light. The first aperture device receives the first color light and the first aperture device can be controlled to modify a frequency of the first color light to the first light valve. The second light valve receives at least a portion of the first residual light. The first aperture device could also be controlled to substantially block at least a portion of the first color light.

    Abstract: An apparatus is disclosed comprising a lamp which produces a first light which may be a white light; a first light valve, a second light valve, and a first aperture device, which may be a first electronically switchable filter. The first aperture device or the first electronically switchable filter function as selectively variable color separators. The first aperture device or the first electronically switchable filter each can be placed in a first state where the first light is separated into a first color light and a first residual light, and a second state where the first light is separated into a second color light and a second residual light. The first light valve receives the first light in the first state and the second light in the second state. The second light valve receives at least a portion of the first residual light in the first state or at least a portion of the second residual light in the second state.

  • Patent number: 5459591
    Abstract: The present invention relates to beam steering and scanning devices which utilize an imaging cell which incorporates a solid-state cholesteric liquid crystal (CLC) element, an electronically controlled, variable half-wave retarder and a source of circularly polarized light. The CLC element is disposed at an angle (45.degree.) relative to the path along which light from the source is projected and is designed to reflect, at a given wavelength, one circular polarization of light and transmit the other. Using this characteristic, light of one polarization or the other is presented to the variable retarder and depending on whether or not it is actuated, light is either diverted into another orthogonal path or remains in the original path. If another similar imaging cell is disposed in the orthogonal path, light incident on that cell can also be diverted into yet another path or transmitted along the orthogonal path under control of a half-wave retarders associated with said another imaging cells.
