摘要： Methods and apparatus are provided for a backlit display with variable luminance and chrominance. The apparatus comprises i groups of LEDs of different colors and one or more sensors optically coupled to the LEDs. The combined light produced by the LEDs is directed to a transmissive liquid crystal display, preferably through a diffusing layer. The sensors monitor the output Si of each group of LEDs. Si for each group of LEDs is multiplied by a chrominance determining parameter Ki to obtain Ki*Si which is then compared to a commanded luminance signal LC to obtain LC−Ki*Si, which difference is used to adjust the drive current to each group of LEDs to achieve LC with the desired chrominance set by Ki. By changing Ki and LC the chrominance and luminescence of the display may be varied and aging effects compensated.

摘要： A fluorescent lamp system is provided that facilitates high-brightness in a compact size needed for liquid crystal displays. The fluorescent lamp system comprises a lamp having a plurality of interdigitated legs arranged in multiple planes. By arranging the interdigitated legs in multiple planes, the lamp system efficiently fills the available space, thus maximizing the lamp surface area in general, and the lamp surface area oriented toward the display in particular, all while maintaining relatively small overall dimensions. The lamp system is thus able to provide the high-brightness needed for displays in a compact size.

摘要： Methods and apparatus are provided for projecting light carrying a data image. The apparatus comprises a first layer having regions of electrically alterable variable light transmittance adapted to form the data image, and a hollow cavity backlight having a light exiting surface coupled to the first layer and adapted to provide light to the first layer through the light exiting surface from one or more light emitters some of which point in a principal direction other than at right angles to the light exiting surface. In a preferred embodiment, LEDs are used as the light emitters and are preferably mounted on one or more printed circuit boards or other support tilted at non-zero angles with respect to the light exiting surface.

摘要： A flat lamp system is provided that facilitates improved reliability and performance in a display system. The flat lamp system provides improved reliability by forming multiple lamps in a single substrate. These multiple lamps provide redundancy and thus increase the reliability of system. Specifically, when one or more lamps in the system fails, the remaining lamps can be used to provide the luminance needed for the display. The multiple lamps are provided by forming multiple distinct channels in the substrate, and forming a cathode at each end of each channel. Each channel and its corresponding cathodes comprise a lamp that can be used to light the display.

摘要： An aperture lamp system that facilitates improved reliability and performance in a display system is provided. The aperture lamp system provides improved reliability by providing a second lamp coupled to a first lamp though a coupling aperture. When the first lamp fails, the second lamp can be used to provide illumination to the display. Specifically, light from the second lamp passes through the coupling aperture to the first lamp, where it can exit the first lamp and illuminate the display. Thus, by coupling the first and second lamps together through a coupling aperture, a lamp system is provided where either the first lamp or second lamp can be used to provide illumination for the display. Thus, the first and second lamps provide redundancy, with this redundancy used to improve the reliability of the display system.

摘要： A lamp driver system that facilitates improved reliability and performance for a display system is provided. The lamp driver system includes a fault detector and an output steering device. The fault detector determines when a failure occurs in a lamp illuminating the display system. The output steering device selectively drives the lamps to illuminate the display system. Specifically, when a failure in a first lamp is detected by the fault detector, the output steering device is used to selectively drive a second lamp to provide the needed illumination to the display system. The lamp driver system thus can provide redundancy in the display system by automatically switching to a backup lamp when a failure in the first lamp is detected. This redundancy can improve the reliability and performance of the display system.
