  • Patent number: 7467882
    Abstract: The present invention discloses a LED (Light-Emitting Diode) heat-dissipating module, which comprises a heat-dissipating fin, a heat-conduction pipe, a LED illumination module and a casing. The heat-dissipating fin has an insertion/press-fit member inserted by or press-fitted to the heat-conduction pipe. The heat-conduction pipe has a contact region contacting the LED illumination module. In the application of the present invention, the LED illumination module is installed on the contact regions of several heat-conduction pipes inserted into or press-fitted to the heat-dissipating fins; thus, the heat generated by the LED illumination module can be effectively dissipated. Then, the LED illumination module is placed inside the casing having an accommodation space. Thus, heat can be conducted via the heat-conduction pipe to the heat-dissipating fin and then fast dissipated therefrom even though the LED illumination module is placed inside the casing.

  • Patent number: 7360943
    Abstract: A liquid crystal display device includes a display unit, a back light assembly having a light source, a light guiding plate, a light focusing portion, and a mold frame divided into a first frame and a second frame. The mold frame receives the display unit and the back light assembly. The first frame receives the light guiding plate and the light focusing portion and the second frame receives the light source. A reflection sheet is integrally formed at an inner surface of the second frame so as to perform the function of a lamp reflector. Accordingly, a lamp cover is not required so that the number of parts and the manufacturing cost are reduced. A lamp can be exchanged by simply separating the second frame from the mold frame, so failure of the light source caused by friction with other elements is reduced when exchanging the lamp.

  • Patent number: 7360940
    Abstract: An exemplary backlight module (5) includes a light guide plate (54) having a light incident surface (546), and a circuit board (62) disposed adjacent to the light incident surface. A pair of protrusions (544) of the light guide plate engages in a pair of fixing holes (524) of the circuit board, thereby fixing the circuit board and the light guide plate together. The backlight module may further include one or more optical films. In such case, the above-described fixing means may further include a plurality of side-blocks or a plurality of corner-blocks integrally formed on a light emitting surface of the light guide plate.

  • Patent number: 7357559
    Abstract: The present invention is broadly directed towards a receiving container for an LCD apparatus for securing a lamp and lamp wiring connected to a lamp. The receiving container has features for substantially preventing the lamp wiring from being disconnected from the lamp. For example, a first through-hole for receiving the lamp wiring, a first trench, securing members, and securing projections are utilized to substantially prevent lamp wiring from being disconnected from a lamp. Additionally, the LCD apparatus is easily handled, dissipates heat effectively, and has a light weight.

  • Patent number: 7344295
    Abstract: The backlight assembly includes a lamp unit, a light guide plate and a receiving container. The light guide plate includes a light exiting surface, a light reflecting surface facing the light exiting surface, and side surfaces. The receiving container includes a frame plate and sidewall protruding from an outer edge of the frame plate to form a receiving space for receiving the lamp unit and the light guide plate. The first distance between an inner surface of the sidewall and an outer surface of the light guide plate at a first region is greater than a second distance between the inner surface of the sidewall and the outer surface of the light guide plate at a second region. The light guide plate is more spaced apart from the sidewall at the corners where much noise was made, in a general backlight assembly, so that the noise is reduced.

  • Publication number: 20080062722
    Abstract: The backlight module in the flat panel display (FPD) includes a frame that resides between the backlight module and the cover of FPD display, and has an inclined plane with an angle between the optical film. The inclined plane causes the touching area broader than the parallel plane does, thus it will absorb more stress force and avoid displaying defects in the FPD panel. Using this structure, the pressure transformed from the FPD cover stresses the inclined plane and forces it to contact the FPD's back light module on broader area in reducing the pressure per unit's area.
