  • Patent number: 7327414
    Abstract: An LCD device for stably fixing a light-guiding plate is disclosed. The LCD includes a support main; a lamp provided along one side of the support main; a light-guiding plate provided in the support main opposite to the lamp; and at least one fixing device provided on an inner surface of the support main, to prevent the light-guiding plate from being moved. The fixing device contains multiple plates arranged in a C shape. Slits are formed in the center plate. An elastic plate is disposed between the slits and a projection is disposed on the elastic plate. The projection contacts the light-guiding plate. The support main contains a recess into which the projection moves when the light-guiding plate expands and the elastic plate deforms.

  • Patent number: 7213960
    Abstract: A backlight unit assembly using a light emitting diode array in a liquid crystal display device is disclosed in the present invention. The backlight unit assembly includes a light emitting diode array having a plurality of red, green, and blue light emitting diodes emitting respective light, a first housing concentrating the light emitted from the light emitting diode array to a first direction, a sub-light guiding plate positioned at one side of the light emitting diode array mixing the light to form white light, a main-light guiding plate guiding the light incident on the sub-light guiding plate to a second direction, and a pair of holders at the left and right side portions of the light emitting diode array preventing the light from leaking to the outside of the backlight unit assembly.
