    摘要: Electrooptic devices (100, 600, 700) include a left handed (102, 708) and right handed (104, 710) cholesteric phase liquid crystal layers. Electrodes (120, 122, 124, 126, 602, 604) or magnetic coils (704, 706) are used to apply electric or magnetic fields perpendicular to helical axes of the cholesteric phase liquid crystal layers. The fields lengthen the helical pitch of the liquid crystal layers thereby shifting the reflectance of the liquid crystal layers to longer wavelengths. Spectral reflectance of both left and right hand polarized light is controlled by the electrooptic devices.

    摘要: Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Each of a set of imagers produces a portion of the final image. Relay lenses then tile the individual image portions together into a combined image. 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. The individual images are tiled together within the microprojector itself rather than on a projection screen. This allows the tiling to be adjusted once at the factory and set forever. In some embodiments, the light created for use by the microprojector is split by a polarizing beamsplitter. Each resultant polarized beam is then sent to an imager. Another polarizing beamsplitter combines the individual images.

    摘要: Disclosed are image expanding lenses, display devices, and electronic devices incorporating the disclosed image expanding lenses. In accordance with a disclosed image expanding lens, the image viewed by the user is larger than the active area of the LCD panel underneath the lens, so that the border around, for example, the LCD display is hidden from viewing. The image expanding lenses may include a non-uniform transparent substrate, having for example, a wedge shape that may be the top surface of the display. The substrate in combination with prismatic films may bend the light output from an array of pixels so that the image hides the border of the display device. In this way, an electronic device can render an edgeless image to a viewer since the image of the electronic device is projected beyond an edge of the display device of the host electronic device.

    摘要: A video projector includes a reduced size spatial light modulator (400) that spatially modulates light from a light source (502) according to only a portion (e.g., ½) of a video frame at a time. A beam steerer (508, 600, 1600) steers spatially modulated light from the spatial light modulator to a correspond region (e.g., upper half, lower half) of a projection screen/surface (512) and one or more lenses (506, 510, 702, 802, 1002, 1008, 1100, 1300, 1502) insure that the spatially light modulator (400) is imaged onto the projection screen/surface (512).

    摘要: A method and apparatus for controlling light intensity from two or more light sources. A timing scheme is used to modulate the light sources. Light from the light sources is combined to form a beam and a photo-sensor senses the beam. In a time interval when only one of the light sources is activated, the signal from the photo-sensor is monitored and used in a feedback control circuit to control the active light source.

    摘要: A color tunable pixel (100) includes a cholesteric liquid crystal (110). The helical pitch of the cholesteric liquid crystal (110) is controlled by applying electrical fields (202, 302) of varying strength and/or frequency perpendicular to an initial helical axis (H) of cholesteric liquid crystal (110) in order to shift the hue of light reflected by the cholesteric liquid crystal (110). The reflectivity of the cholesteric liquid crystal (110) may be controlled by applying an electric field (402) perpendicular to the initial helical axis (H) at a frequency at which the cholesteric liquid crystal (110) exhibits a negative dielectric anisotropy. Alternatively the visible light reflectivity may be controlled by applying an electric field to shift the reflectance of the cholesteric liquid crystal (110) into the infrared portion of the spectrum, or in another embodiment by allowing the cholesteric liquid crystal (110) to revert to an ultraviolet reflected state.
