  • Patent number: 7433002
    Abstract: The present invention is related to a method of method of manufacture of a reflective polarizing film that can improve brightness of a liquid crystal display device remarkably by making a liquid crystal film that can cover visible light by using cholesteric liquid crystal layers having different selective light-reflection central wavelengths, attaching a quarter wave (¼ ?) retardation film on top of the liquid crystal film, and adding prism patterns to the opposite side of the liquid crystal film. The reflective polarizing film of the present invention is characterized by that two or more cholesteric liquid crystal layers having different selective reflection wavelength regions are laminated in order from a shorter wavelength to a longer wavelength, and brightness of a liquid crystal display device is maximized owing to an integrated film manufactured by attaching a ¼ ? retardation film onto cholesteric liquid crystal layers and forming prism patterns onto the opposite side.

  • Patent number: 7316442
    Abstract: A detachment prevention device of a seat rail for a vehicle, designed to allow an outer side wall of a lower rail to be extended in the event of a crash and to suppress bent portions from being deformed, thereby ensuring passenger safety. The seat rail comprises a lower rail fixed to a bottom surface of a vehicle body by means of fixing means, an upper rail located on the lower rail and coupled thereto, bent portions formed at both sides of the lower rail and the upper rail, respectively, such that the lower rail is hooked to the upper rail by means of the bent portions, a bracket extended from a center of the upper rail to an upper portion thereof in order to fix a vehicle seat to the upper rail, and a buckle fixed to the bracket to fasten a seat belt.

  • Publication number: 20070013618
    Abstract: In a plasma display device and a driving method therefor, address period operation is performed on a first group of first electrodes during at least a part of a period during which a sustain period operation is performed on a second group of first electrodes, and a reset discharge is generated by applying a first voltage to the first group of first electrodes, a second voltage to a plurality of second electrodes, and a third voltage to a plurality of third electrodes so that a first voltage difference between the first voltage and the third voltage is higher than a second voltage difference between the first voltage and the second voltage.

  • Publication number: 20060204681
    Abstract: Disclosed is a broadband reflection type brightness enhancement polarizer, which includes a cholesteric liquid crystal film laminate having a broadband selective reflecting wavelength range in which a plurality of cholesteric liquid crystal films having selective reflecting wavelength ranges different from each other by having different mixture ratios of a curable nematic liquid crystal compound expressed by the chemical formula 1 and a curable chiral compound expressed by the chemical formula 2 are laminated; and a film having ¼? phase difference laminated on one surface of the cholesteric liquid crystal film laminate. This polarizer has wide selective reflecting wavelength ranges of the cholesteric liquid crystal films composing the polarizer, so the entire visible ray range can be covered just by laminating several cholesteric liquid crystal films.
