Abstract:
The present invention provides a backlight module, which includes a backplane, a backlight source arranged inside the backplane, a light guide plate arranged inside the backplane, an optic film assembly arranged on the light guide plate, and a split mold frame arranged inside the backplane. The split mold frame includes a plurality of spaced corner pieces respectively set on the optic film assembly. The corner pieces have a support surface that is distant from the optic film assembly for supporting thereon a liquid crystal display panel. The backlight module of the present invention uses an upper surface of a split mold frame to serve as a support surface for a liquid crystal display panel thereby enlarging the supporting area for the liquid crystal display pane, improving supporting stability and also effectively preventing the occurrence of light leakage, ensuring luminance of the backlight module, and enhancing optic grade.

The direct-light backlight module includes at least two light sources; a diffuser place, disposed above the light sources; a reflection plate, disposed beneath the light sources; and an optical film, disposed on top of diffuser plate, further including a plurality of via holes disposed at corresponding areas on the optical film between two neighboring light sources; and further including a liquid crystal panel, disposed on top of the optical film. Through this manner, the present invention can realize the thin design of liquid crystal display device, with the luminance uniformity of backlight module.
Abstract:
The present invention discloses a backplane, a backlight module, and an LCD device. A backplane comprises a heatsink plate and a supporting plate connected with the heatsink plate; the heat conductivity of the heatsink plate is larger than that of the supporting plate; the heatsink plate or the supporting plate is provided with reinforcing ribs in the joint. 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. The reinforcing ribs are added in the joint so that the strength of the joint is enhanced and the backplane is tightened and durable.
Abstract:
The invention relates to the field of LCDs, and more particularly to a backlight module and an LCD device comprising the backlight module. The backlight module includes a middle frame, a light guide panel, and a light source; the backlight module further includes a shielding structure which is used for preventing the light of the light source from being directly emitted from the gap between the middle frame and the light guide panel; the shielding structure includes a groove arranged in the middle frame, and a convex lug arranged on the light guide panel; the convex lug is arranged in the groove. Because of the existence of the shielding structure, the light cannot be directly emitted onto the optical film from the gap between the middle frame and the light guide panel; thus, the problem of light leakage is solved; therefore, the bright line and facula cannot be generated on the LCD panel, thereby improving the quality of the LCD device.
Abstract:
The present invention provides a combined backplane and a backlight module using the combined backplane. The combined backplane includes a body and a first bracket coupled to the body. The body includes a base plate. The first bracket includes a first bottom plate and a first side plate perpendicularly connected to the first bottom plate. The first bottom plate has an end distant from the first side plate and coupled to an end of the base plate. The base plate and the first bracket are made of different materials. The combined backplane of the present invention is formed by combining a body with a bracket. The body is made of a high-strength material to improve overall strength of the backplane and the bracket is made of a material of high thermal conductivity to improve overall thermal conductivity of the whole backplane.

An LCD device includes a panel module and a back light module. The back light module includes a light guide plate having a light incident surface; a bezel for receiving the light guide plate, including a bottom plate and side walls surrounding the bottom plate; a reflective sheet disposed between the light guide plate and the bottom plate of the bezel; at least one lighting unit disposed in a position corresponding to the light incident surface; and a fixing unit including at least two fixing members, each fixing member has a base position and a bent portion vertically extending from at least one end of the base position. The top surface and the inner surface of the base position are closely attached to the light guide plate and the outer surface of the bent portion opposite to the inner surface thereof is closely attached to the side wall.
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 invention relates to the field of LCDs, and more particularly to a frame for an LCD device and an LCD device including the frame. The frame includes four edge frames; at least one pair of mutually parallel edge frames of the four edge frames are separately provided with a ripple structure. The ripple structure of the invention is similar to a telescopic ripple part of a drinking straw. The dimensions of one pair of edge frames provided with the ripple structure in the length direction can be adjusted. When the dimensions of two or more kinds of frames are different but similar, a same frame can be shared to achieve the effect of one object with multiple purposes, thereby reducing the number and development cost of special moulds, shortening the development cycle of the product, and avoiding the problem that a great deal of stagnant materials are inconveniently handled when developing single device. Thus, the aim of reducing cost is achieved.

The present invention provides a middle frame and a liquid crystal display module. The middle frame comprises a plastic portion and a rubber portion. The plastic portion and the rubber portion are enclosed to form the middle frame. According to that, the present invention can reduce the manufacture cost of the middle frame and increase the elasticity of the middle frame.
Abstract:
The invention relates to the field of LCDs, and more particularly to a frame for an LCD device and an LCD device comprising the frame. The frame for an LCD device includes an extrusion made of plastic material, and the extrusion forms the rims of the frame after being bent. The frame for an LCD device of the invention is made of plastic material and comprises an extrusion made of plastic material. The extrusion forms the rims of the frame after being bent. By using the characteristics that the shape of the cross section of the extrusion is fixed, but the length is not limited basically, the extrusions is cut into corresponding length after determining the size of the frame, and then the rims of the frame are partially or totally formed by bending the extrusion. The extrusions with the cross sections of the same shape can be made into frames of any size. Because the sharing performance of extrusion dies is improved, and the number of special purpose dies is reduced, thus the cost of frames is further reduced, and then the development cycle of LCD devices is shortened.
