  • Publication number: 20130299869
    Abstract: A light-emitting module includes a light-emitting diode package structure and an insulating support structure. The light-emitting diode package structure includes a package base and at least two leads. The package base has a first surface, and each lead has a bonding surface. The insulating support structure has a second surface and a third surface opposite to each other, and the insulating support structure is disposed under the package base, so that the first surface is in contact with the second surface. The bonding surfaces and the third surface are located in different planes.

  • Patent number: 8376604
    Abstract: A frame structure of a backlight module includes a body and a mold frame. A side wall surrounds a bearing surface of the body, and the side wall has at least one stopper and at least one positioning hole. A side edge of the mold frame has at least one positioning post. When the mold frame is disposed on the side wall, the side edge of the mold frame leans against the stopper, and the positioning post of the mold frame is embedded in the positioning hole.

  • Patent number: 8345179
    Abstract: A flat panel display module is introduced herein, which principally includes an upper bezel, a liquid crystal panel, a frame, an optical film set and a printed circuit board assembly (PCBA), wherein various types electrical components mounted on the PCBA are capable of being completely or mostly accommodated within a caved structure constructed within the inside of the flat panel display module so as to reduce a thickness of the whole flat panel display module. Simultaneously, a better structural strength for the whole flat panel display module can be achieved therefore by closely stacking up the above-mentioned elements of the whole flat panel display module.

  • Patent number: 8064007
    Abstract: The present disclosure is a backlight module including a light guide plate, a supporter, and a light source module. The light guide plate has a light incident side. The supporter has a bottom plate, a sidewall, and a top plate corresponding to the bottom plate. The bottom plate extends from a first end of the sidewall toward the light guide plate, and the top plate extends along a second end of the sidewall toward the light guide plate. The length of the sidewall is longer than the length of the top plate, such that the top plate corresponding to the sidewall forms at least one breach to expose the second end of the sidewall. The bottom plate, the top plate, and the sidewall together form an accommodating space, and the light incident side of the light guide plate is disposed between the top plate and the bottom plate. The light source module is disposed in the accommodating space and partially exposed through the at least one breach.

  • Patent number: 8049834
    Abstract: A display device and a backlight module thereof are provided. The display device further includes a display panel having a display area. The backlight module is disposed under the display panel and includes a light source holder, a light source, and a light guide plate. The light source holder has a sidewall, a top plate, and a bottom plate, wherein the bottom plate partially overlaps the display area of the display device. The light guide plate is disposed corresponding to the display area of the display device and has one end located in an opening between the top plate and the bottom plate. A thermal isolating layer is interposed between the light guide plate and a portion of the bottom plate which corresponds to the display area. The perpendicular distance between the light guide plate and the portion of the bottom plate overlapping the thermal isolating layer is greater than a perpendicular distance between the light guide plate and the other portion of the bottom plate.
