  • 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.
