  • 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: 6799987
    Abstract: A wire-connecting device that is capable of preventing deterioration or breakage of a wire connected to a lamp electrode of a liquid crystal display module. In the device, a clamp presses and secures the electrode to the wire. The lamp electrode and the wire are connected to each other by means of the clamp, providing a secure conductive connection. The wire-connecting device also prevents the penetration of lead by capillary action into the conductive core of the wire, thereby preventing the wire from becoming brittle and subject to breakage as a result of penetrated lead curing in the conductive core of the wire.
