    摘要: Light from a plurality of light sources is combined in a beam combiner. Photo-sensors are used to sense the intensity of each light source. Signals from the photo-sensors may be used to control the intensity of the light sources. The photo-sensors can be located in the beam combiner or located in the fringe of a collimated beam produced by the beam combiner. The illumination system has application in laser-scanning micro-projectors, for example.

    摘要: Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Light created for use by the microprojector is split by a polarization-sensitive element into a number of beams. Each polarized beam is then sent to an imager. Each imager modulates the light beam to produce a portion of the final image. Another polarization-sensitive element directs the individual image portions through a projection lens system so that when they are projected, the individual image portions tile together into a seamless projected image. This technique uses essentially all of the original light, doubling the lighting efficiency of previous devices. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers.

    摘要: Electrophoretic displays (100, 400) comprise suspensions in one or more bodies of liquid (116, 418, 426) of reflective particles (118, 420), and photoluminescent particles (120, 422). The one or more bodies of liquid are located between a front wall (104, 402) and a back wall (102, 404). Electrodes (128, 129, 410, 412) and optionally a transparent ground plane layer (124) are provided for applying electric fields to the suspensions according to image information. The reflective particles and the photoluminescent particles are characterized by the electrophoretic mobilities of the same sign, and therefore move in the same direction in response to applied fields. A source of radiation (140, 428) capable of exciting photoluminescence of the photoluminescent particles is optically coupled to the liquid suspensions. An optical filter layer is optionally located at the front of the displays. The display is capable of operating under a wide range of ambient light conditions.

    摘要: Liquid crystal displays (10) and touch sensitive displays (41) are stacked with one or more solar cells (15) such that light passing through the displays will illuminate the light receiving active surface of the solar cells (15). No reflector or polarizer need be used when the liquid crystal display (10) uses cholesteric or polymer dispersed liquid crystals. When using supertwist nematic or twisted nematic liquid crystals, a reflector (21) can be used that comprises a selective color reflector. The resultant display/solar cell can be utilized in combination with a device such as a wireless communications device (62) with the solar cell (15) providing electricity to the display (61), the wireless communications device (62), or both. A mask (71) can be used to occlude surface features on the solar cell (15) as appropriate to provide a substantially uniformly colored appearance.
