  • Patent number: 7276972
    Abstract: A distributed amplifier with a simple structure that permits miniaturization of circuit in which the input-side transmission line of the distributed amplifier is constituted by a coplanar line having a signal line and a ground face formed on the upper face of a dielectric substrate and the output-side transmission line of the distributed amplifier is constituted by a microstrip line having a signal line formed on the upper face of the dielectric substrate and a ground face formed on the lower face of the dielectric substrate. In addition, a plurality of amplification transistors is formed on the upper face of the dielectric substrate and each of the electrodes is connected to the signal line or the ground face that is formed on the upper face of the dielectric substrate. Because a large transistor-drive current does not flow to the input-side transmission line, the signal line can be made narrow and there is no increase in the required surface area even in the case of a coplanar line.

The circuit for driving the liquid crystal panel of a liquid crystal projector having a plurality of lamps as light sources has a CPU circuit for managing the overall system and data of the liquid crystal projector, a video signal processing circuit for converting a video signal input from an external source into a digital signal, and a panel correcting circuit for correcting the digital video signal generated by the video signal processing circuit depending on characteristics of a liquid crystal panel of the liquid crystal projector so as to match the liquid crystal panel. The CPU circuit outputs corrective data to the panel correcting circuit depending on how the lamps are energized, and the panel correcting circuit corrects the video signal using the corrective data.

  • Patent number: 7221348
    Abstract: A liquid crystal display device is provided which is capable of reducing flicker over all areas of a liquid crystal panel. A common voltage having a predetermined level is fed to the liquid crystal panel and a reference voltage is fed from a digital-analog converter to a liquid crystal driving circuit and an image corresponding to a pixel data signal is displayed. The pixel data signal is reversed relative to a reference voltage for every one horizontal period. The reference voltage having been adjusted so as to be higher in side portions rather than central portions in the liquid crystal panel is applied to the liquid crystal driving circuit. As a result, even if a common voltage is not made uniform through entire portions of a common electrode, adjustment can be achieved so that flicker is minimized over all areas in the liquid crystal panel.

  • Patent number: RE39702
    Abstract: An output light from an a light source lamp unit 8 in a projection-type display apparatus projector illuminates liquid-crystal light valves 925R, 925G and 925B for three colors via an integrator optical system 923. A superimposing lens 930 that is a component of the integrator optical system 923 as a uniform illumination optical system is arranged such that the mounting position of the superimposing lens 930 is fine-adjustable in a direction orthogonal to an optical axis 1a. By fine-adjusting the mounting position of the superimposing lens 930, the position of an illumination area B is adjusted such that the illumination area includes the image forming area A of the liquid-crystal light valve. It is not necessary to assure a wide margin around the image forming area A to cover the offset of the position of the illumination area B. As a result, the utilization of illumination light is heightened and a bright projected image results.

  • Patent number: RE39859
    Abstract: At least one of four rectangular prisms in a dichroic prism is made longer than the other rectangular prisms. Parts of the rectangular surfaces of the long rectangular prisms partially protrude from the rectangular surfaces of the other rectangular prisms in the longitudinal direction. The protruding parts of the rectangular surfaces of the long rectangular prisms are not provided with a dichroic film. Such a construction makes it possible to prevent return light, which returns from the light emitting surface side of the dichroic prism and the dichroic prism, from emitting again from the light emitting surface.

  • Patent number: RE40251
    Abstract: Two polarization conversion element arrays are disclosed. Each polarization conversion element array is composed of a plurality of polarization conversion elements for converting light incident upon the polarization conversion element array to a linearly polarized light beam with a predetermined polarization direction. The plurality of polarization conversion elements are disposed opposite to each other with a predetermined space provided between at about the center of the light-outgoing surface of a lens array in the direction of arrangement. Of the light beams (s-polarized+p-polarized light beams) gathered by the lens array, light beam that is not incident upon the polarization conversion element and passes through the predetermined space is a light beam including a predetermined polarized light beam (s-polarized light beam) that is primarily made to leave the array 320a and an ineffective polarized light beam (p-polarized light beam).
