As a kind of preferred embodiment provided by the utility model, the thickness of the graphite flake is 0.03-0.1mm.
As a kind of preferred embodiment provided by the utility model, the thickness of the copper foil is 0.03-0.1mm.
As a kind of preferred embodiment provided by the utility model, the luminescence component includes FPC and is electrically connected at described LED on FPC.
As a kind of preferred embodiment provided by the utility model, the glue frame be equipped with for FPC by via, it is described FPC is pasted onto by heat-conducting glue in the glue frame.
As a kind of preferred embodiment provided by the utility model, the heat-conducting glue extends on the graphite flake.
As a kind of preferred embodiment provided by the utility model, reflector plate is additionally provided between the light guide plate and bottom plate.
Further, a kind of liquid crystal display die set, including the backlight module described in any of the above item are provided.
The utility model has the following technical effect that:A kind of backlight module provided by the utility model and liquid crystal display die set The bottom plate on the glue frame bottom surface is fitted in by setting, the bottom plate includes PET sheet, fits in the copper foil on the PET sheet With fit in the graphite flake on the copper foil, enable to the frame of backlight module to only have the part of glue frame side wall, can adapt to The requirement of narrow frame can effectively play simultaneously as bottom plate includes PET sheet, copper foil and graphite flake to being led in backlight module The protection of the elements such as tabula rasa, and there is good heat conductivility so that bottom plate has the characteristics that light-weight and perfect heat-dissipating, Effectively the heat generated in backlight module can be shed and the requirement of narrow frame can be met.
Description of the drawings
In order to illustrate more clearly of the technical solution of the utility model embodiment, the attached drawing of embodiment will be made below simple Ground introduction, it should be apparent that, the accompanying drawings in the following description merely relates to some embodiments of the utility model, rather than to this practicality Novel limitation.
Fig. 1 is a kind of structural schematic diagram of backlight module provided by the utility model;
Fig. 2 is a kind of arrangement schematic diagram of heat-conducting glue provided by the utility model;
Fig. 3 is the arrangement schematic diagram of another heat-conducting glue provided by the utility model.
Specific implementation mode
To make the purpose of this utility model, technical solution and advantage are clearer, below in conjunction with the accompanying drawings to the utility model Embodiment is described in further detail.
As shown in Figure 1, which show a kind of backlight module provided by the utility model, including glue frame 1, it is set in glue frame 1 Light guide plate 2 and luminescence component 3 set on 2 incidence surface side of light guide plate, further include the bottom plate fitted on 1 bottom surface of the glue frame 4, the bottom plate 4 includes PET sheet 41, fits in the copper foil 42 on the PET sheet 41 and fit in the graphite on the copper foil 42 Piece 43.In the present embodiment, the luminescence component 3 includes FPC31 and the LED32 being electrically connected on the FPC31.Due to inciting somebody to action Bottom plate 4 is affixed directly on the bottom surface of glue frame 1, and the frame of backlight module is enabled to only have the part of 1 side wall of glue frame, Neng Goushi The requirement of narrow frame is answered, simultaneously as bottom plate 4 includes PET sheet 41, copper foil 42 and graphite flake 43, specifically, in the present embodiment In, the thickness of the PET sheet 41 is preferably 0.03-0.1mm, and the thickness of graphite flake 42 is preferably 0.03-0.1mm, the copper foil Thickness be 0.03-0.1mm, PET material has excellent mechanical performance, rigidity is high, hardness is big, good toughness, impact resistance, antifriction It wipes, creep resistance.Chemical resistance is good, therefore can be effectively played to elements such as light guide plates in backlight module after PET sheet 41 is arranged Protection, moreover, provided with after copper foil 42 and graphite flake 43, copper foil 42 has a good heat conductivility, graphite flake 43 conduct heat it is fast, Thickness is thin, light-weight, and can realize Homogeneouslly-radiating with copper foil good fit, such bottom plate 4 has light-weight and scattered The heat generated in backlight module can effectively be shed and can meet the requirement of narrow frame by the characteristics of good in thermal property.
Further, the bottom plate 4 is pasted on by black glue 5 on the bottom surface of the glue frame 1.Black glue 5 can play Good interception is not provided with the part extended to 1 side of glue frame, therefore since bottom plate 4 is directly adhered in glue frame 1 It is easy to happen light leakage phenomena between bottom frame 4 and glue frame 1, glue can effectively be avoided by pasting glue frame 1 and bottom plate 4 by black glue 5 The generation of light leakage phenomena between frame 1 and bottom frame 4 improves product quality.
Further, as described in Figure 2, the glue frame 1 be equipped with for FPC31 by via, the FPC31 passes through heat conduction Glue 6 is pasted onto in the glue frame 1.In this way, FPC31 can be extended outwardly by the via of glue frame 1 thus with realizing and external electricity The electric connection of road plate.Further, as shown in figure 3, the heat-conducting glue 6 is also extend on the graphite flake 43, to It in the heat transfer to graphite flake of LED32 and FPC31 generations, can will directly contribute to dissipating for luminescence component 3 by heat-conducting glue 6 Heat, while heat-conducting glue 6 can also have the effect of further preventing light leakage, in the present embodiment, the light guide plate 2 and bottom plate 4 Between be additionally provided with reflector plate 7.2 light-emitting surface side of the light guide plate is also sticked and has optical diaphragm group 8, and the optical diaphragm group 8 can To include diffusion barrier and brightness enhancement film.
Further, the present embodiment also provides a kind of liquid crystal display die set, including above-described backlight module.
The embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously Cannot it therefore be interpreted as the limitation to the utility model patent range, as long as using the form institute of equivalent substitution or equivalent transformation The technical solution of acquisition, shall fall within the scope of the present invention.
