  • Patent number: 7929072
    Abstract: An object of the present invention is to reduce the exterior of a display device while retaining a display screen at a certain size. A liquid crystal display panel including a TFT substrate formed with a glass substrate and a color filter substrate is stored in a frame made of a metal. In order to avoid the direct contact between the glass substrate and the frame made of a metal, part of an optical sheet included in a backlight disposed behind the liquid crystal display panel is extended to lie between the liquid crystal display panel and the frame, and is regarded as a spacer. Since the thickness of the optical sheet is as small as 0.06 mm, the spacer hardly affects the external dimensions of a display device. Consequently, while a crack of the glass substrate is prevented, the exterior of the display device can be reduced.

  • Patent number: 7554620
    Abstract: An ESD structure in an LCD module mounting structure in a terminal for mounting an LCD module on the inner surface of a case frame to be exposed through an opening of a predetermined size formed on the case frame. In the ESD structure, an EMI shielding is formed to be electrically connected to a main board of the terminal and grounded by coating EMI spray all over the inner surface of the case frame including a part of an overlap between the inner surface of the case frame and the LCD module. At least one through hole penetrates from the inner surface to the outer surface of the case frame at an appropriate portion of the overlap. Conductive means electrically connects the inner surface of the through hole to the EMI shielding. Therefore, externally introduced static electricity is actively grounded inside the terminal along the through hole.
