  • Patent number: 7549760
    Abstract: A backlight assembly includes a plurality of lamps, a first reflecting plate and an optical member. The lamps are disposed substantially parallel with each other and generate light. The bottom reflecting plate is disposed under the lamps to reflect the light. The first reflecting plate is disposed over the lamps to transmit and reflect the light and has a plurality of penetration holes for transmitting the light. The optical member is disposed over the first reflecting plate. The formation density of the penetration holes increases as a position of the penetration holes approaches an intermediate region between adjacent lamps from a region corresponding to a position of the lamps.

  • Publication number: 20080018828
    Abstract: In a backlight assembly, a liquid crystal display (“LCD”) apparatus including the backlight assembly and a method for manufacturing the backlight assembly, the backlight assembly includes first, second, third and fourth lamps. The first to fourth lamps respectively face first to fourth side surfaces of a light-guide plate. Each include an input and an output terminal. The output terminals of the first and second lamps and of the third and fourth lamps, and the input terminals of the first and fourth lamps and of the second and third lamps, are adjacent to each other. A pair of the output terminals of the first and second lamps or the third and fourth lamps is connected to each other, so that the pair of lamps is arranged in an L-shape. The pair of the output terminals may be fed back to each input terminal, or grounded to a receiving container.

  • Publication number: 20070188102
    Abstract: A backlight unit using a microwave plasma ultraviolet lamp as a light source and a liquid crystal display including the backlight unit. The backlight unit for a liquid crystal display comprises a tube filled with discharge gas, a cavity resonator in which one end of the tube is inserted, a magnetron for generating microwaves and supplying the generated microwaves to the cavity resonator, a magnetron driver for driving the magnetron, and a phosphor layer for converting ultraviolet light generated in the tube into visible light.

  • Patent number: 6532362
    Abstract: The present invention relates to a temporary reference number (TRN) for Over The Air Registration (OTAR) of a mobile telephone, particularly to Over The Air Service Provisioning (OTASP) method by using the TRN in mobile communication system. The TRN packet includes a header code having fixed bits for indicating the OTAR request call through the OTASP, a point code having fixed bits for identifying the exchange which switches the OTAR call through the OTASP, and a mobile telephone identity code having fixed bits for identifying the mobile telephone which requests the OTAR call.
