摘要： A back-lighted color LCD display is formed by placing a single matrix of liquid crystal devices (LCDs) over a bank of red, green and blue fluorescent lamps. The LCD matrix is operated to sequentially form separate red, green and blue images synchronous with the illumination of the respective red, green and blue lamps. The flashing of the sequential red, green and blue images is perceived as a color image. The images are scanned, one line at a time, onto the LCD matrix. The bank of fluorescent lamps includes several lamps of each color which are arranged in parallel with the lines of the LCD matrix. The different lamps of each color are activated in synchronism with the scanning of the LCD matrix. Each LCD in the matrix includes a rapidly varying liquid crystal material, sandwiched between conductive plates. The electric field between the conductive plates may be controlled by a polysilicon thin-film transistor.

A plurality of combiner circuits are provided, one for each stage of each of the shift registers. Each combiner circuit is configured to provide an electrical conduction path for the select signal between successive stages in each of the shift registers. When a fault is detected in a stage of one of the shift registers, the combiner circuit coupled to the output of the defective stage reconfigured to route the select signal from the corresponding stage of the other shift register to the next stage of the one shift register. Full select shift register redundancy is provided, even if both shift registers have faulty stages.

摘要： Apparatus provides an incident light beam which illuminates the surface of a grooved disc, having signal elements recorded therein in the form of a succession of spaced apart depressions, with a light spot that spans a plurality of convolutions of the groove. The structure of the groove convolutions and signal elements forms a two-dimensional diffraction grating which reflects light into a plurality of diffraction order beams. Photodetectors, respectively positioned to intercept several of the reflected beams provide outputs corresponding to the light power in the respective reflected beams. Estimations of signal element depth in the region illuminated by the light spot may be made from the measured light powers.

摘要： A defect detection apparatus is disclosed for optically inspecting a spiral groove of a video disc record by directing a coherent light beam at the grooved surface of the disc. The incident beam illuminates the grooved surface with a light spot that spans a plurality of groove convolutions. The structure of the illuminated region on the grooved surface serves as a diffraction grating for diffracting the incident beam into discrete diffraction orders. Relative motion is established between the disc surface and the incident beam in a manner causing the illuminating spot to rapidly scan the grooved surface in a coarse spiral pattern. A lens system is positioned to collect the light from a single beam of a particular group of non-zero diffraction order beams and to focus this non-zero order beam onto a photodetector. When a defect in the groove pattern exists in the illuminated region the measured power of the non-zero order beam will fall below its normal level. The fractional decrease in the measured power is an indication of the relative size of the defect.

摘要： A light-emitting fiber comprises an optical fiber having a number of light-emitting elements disposed along the length of one surface thereof. The light-emitting elements include a segmented hole injecting electrode on which an electro-luminescent material, such as an OLED material, is disposed and an electron injecting electrode overlying the OLED layer. The segmented hole injecting electrodes are connected together by an electrical conductor disposed on a side surface of the optical fiber. Electrical contacts connect to the electron injecting electrode and are disposed, at least in part, so as to not overlie the OLED layer. The electrodes, OLED material and contacts are deposited on the optical fibers by mask deposition, preferably utilizing masks adapted to contemporaneously process a plurality of fibers.
