Abstract:
The invention provides an LCD module and a frame thereof. The frame comprises a plurality of segmented pieces constituting the frame; the frame comprises a front frame, and a middle frame; the structure of the segmented piece(s) constituting the front frame is the same as that of the segmented piece(s) constituting the middle frame. Because the front frame and the middle frame of the LCD module of the invention are comprised of a plurality of segmented pieces of the same structure, the segmented pieces constituting the front frame can be superposed outside the segmented pieces constituting the middle frame, and then the front frame and middle frame of different sizes can be respectively formed. Thus, because the segmented pieces constituting the front frame and middle frame are of the same structure, the segmented pieces can be produced by only one mold, and the front frame and the middle frame can be produced just by the same mold, thereby saving the production cost. In addition, the segmented pieces can be cut only on one section without singly producing each segmented piece, thereby further reducing the production cost of LCD modules.

The invention provides an LCD device, a manufacturing method thereof, and an optical film. The LCD device includes optical films, and an LCD panel; an edge(s) of the optical film is provided with a folded edge(s), and the LCD panel is arranged on the folding edges. In the invention, because the folded edges are arranged on the optical film of the LCD device, and the LCD panel is arranged on the folding edges, no interval is reserved between the edges of the LCD panel and the optical films, thereby preventing the LCD device from generating light leakage because the LCD panel is supported by the separated middle frames. In addition, because no interval is reserved between the edges of the LCD panel and the folded edges for support, the whole edges of the LCD panel are continuously supported instead of only supporting the four corners by the separated middle frames, thereby increasing the compression strength of the LCD panel, effectively preventing the black matrix or other structure(s) from moving because of oversize deformation when being stressed, and preventing light leakage and water ripple phenomena.
Abstract:
The invention discloses a front frame and a back light module. The front frame comprises at least one stacked plate which is stacked with the front frame. The invention adds the stacked plate on the front frame which the stacked plate is stacked with, so that the structure thickness of the front frame is increased, thereby increasing the total strength. In case that the strength is increased, the plate thickness of the front frame can be reduced, or some structures of the front frame like side walls can be removed, or structure material with low cost can be employed to achieve the aim of reduction of material cost.
Abstract:
The present invention discloses a backplane of a backlight module, a backlight module and an LCD device. The backplane of the backlight module comprises a heatsink plate with good heat dispersion and a low-cost supporting plate connected with the heatsink plate, wherein the heat conductivity of the heatsink plate is larger than that of the supporting plate. In the present invention, metal with good heat dispersion and common material with low cost are respectively adopted and joined according to different radiating areas of the backlight module; then, the heat dispersion is ensured and meanwhile, the cost is reduced.
Abstract:
A back cover of a liquid crystal display (LCD) for supporting a backlight module is disclosed. The back cover comprises a back cover body and an inset.

Abstract:
The present invention provides a backlight module and a light-emitting source package structure thereof. The light-emitting source package structure comprises: a heat-dissipation base, at least one chip and a heat-dissipation fixing element. The heat-dissipation base has a connection hole. The heat-dissipation fixing element further has a connection post and a heat-dissipation fin with an abutting surface, and the connection post of the heat-dissipation fixing element passes through a through hole of a fixed plate to fix in the connection hole, so that for closely aligning the abutting surface of the heat-dissipation fin and can abut against the fixed plate. Thus, and the heat-dissipation base and the heat-dissipation fixing element are stably fixed on the both sides of the fixed plate to ensure the tightly abutting relationship with the fixed plate and enhance the assembly reliability. Meanwhile, the heat-dissipation fin can additionally increase the heat-dissipation efficiency of the heat-dissipation fixing element. Thus, the temperature of the chip can be surely lowered to prevent from lowing the working efficiency of the chip. Hence, it is advantageous for the chip to stably work, and the lifetime thereof can be increased.
Abstract:
A plastic housing for a liquid crystal display, a manufacturing method thereof and the liquid crystal display are provided, and the plastic housing is an integral plastic housing, including a lower supporting surface and two side frames oppositely disposed on the lower supporting surface. Each of the two side frames is formed with a shoulder on an inner sidewall thereof. The shoulder has a first planar surface parallel to the lower supporting surface. The shoulder further has a second planar surface perpendicular to the lower supporting surface. The height of the second planar surface is equal to or greater than the thickness of a plurality of optical films. The advantage of the present invention is to employ the integral plastic housing to install the optical films and the panel. The integral plastic housing includes two side frames with the shoulders, so that the optical films and the panel can be commonly assembled together with the integral plastic housing. When needing to replace the backlight source, the optical films and the panel can be commonly disassembled together with the integral plastic housing. Therefore, the optical films can be conveniently and speedily disassembled and assembled and it can avoid being polluted during disassembly and assembly. Moreover, the optical films can be more easily fixed because of the embedded engagement effect of the integral plastic housing.
