Abstract
The utility model provides a plastic-frame-free backlight structure, which can reduce the assembling procedures, improve the production efficiency and can reduce the cost by reducing the mould of the die sinking. The backlight structure comprises a light guiding plate, a framework which bears a backlight part and a reflecting sheet that is arranged below the light guiding plate, wherein, the light guiding plate and the framework are of an integrity which is molded by the same mould, and a groove structure which bears the backlight part is arranged on the framework which is connected with the light guiding plate into a whole body. The utility model relates to a backlight source of a TFT glass screen, and in particular to a backlight source of small screens such as MP4 and navigation instrument, which can reduce the cost and can improve the efficiency.
Description
Technical field
The utility model relates to the backlight of TFT glass display screen, particularly relates to the color screen backlight of the small screen such as MP4, navigator.
Background technology
The electronic product of using backlight has GPS navigation instrument, MP4, palm PC etc.Backlight need be formed module with TFT glass and use.
Present general backlight, its structural design all support all parts (as LGP, reflector plate, diffusion sheet, light source, TFT glass etc.) in entire backlight source, its structure structure as shown in Figure 1 with the plastic cement frame as framework.In Fig. 1, LGP 1 embeds in the glue frame 2, is useful on the groove and the limit of each parts of carrying on the glue frame 2.
In the said structure, LGP and glue frame need independent die sinking, have increased the die sinking cost and the glue frame material cost of product like this.It is the basis of follow-up assembling that LGP is embedded in the glue frame, if the assembling of LGP and glue frame is undesirable, causes trouble will for the assembling of the accessory of back, so the assembling of LGP need expend a large amount of time usually.And because product size is very little, manually assembling LGP need be very careful, makes efficiency of assembling undesirable like this, and it is higher to cause cost to compare.
The utility model content
Technical problem to be solved in the utility model is: a kind of back light source structure that does not have the design of plastic cement frame is provided, and this structure can reduce assembly process, enhances productivity, and reduces cost by mould and the material that reduces die sinking.
In order to solve the problems of the technologies described above, the utility model provides a kind of back light source structure that does not have the design of plastic cement frame, comprise the framework of LGP, carrying backlight assembly and be located at reflector plate below the LGP, described LGP and described framework are the integral body that same mould reverse mould is made, be provided with the groove structure of carrying backlight assembly on the framework that fuses with LGP, the framework that itself and LGP fuse is used for mount TFT glass.
Preferably: the groove and the edge that on one side of the framework that fuses with described LGP, are provided with the pcb board of carrying LED.The thickness of described edge is 0.5mm~2mm, is preferably 1mm.
Preferably: on the limit of described reflector plate bound edge is arranged, bound edge gets up the completely encircle of framework.
The beneficial effects of the utility model are:
Compared to existing technology, the utility model adopts LGP to replace the support fixation effect of glue frame in the entire backlight source, so not only can open a cover glue frame mould less, reduces die sinking and product developing expense, can also save glue frame shared cost in backlight.Aspect the production line assembling, can also reduce the operation of one glue frame and LGP assembling, enhance productivity.
Description of drawings
Fig. 1 is the decomposition chart of prior art.
Fig. 2 is a decomposition chart of the present utility model.
The specific embodiment
The utility model provides a kind of back light source structure that does not have the design of plastic cement frame, referring to Fig. 2.
Be applied to the small screen TFT glass modular structure decomposition chart as shown in Figure 2.The structure of this small screen from top to bottom is followed successively by: last chase 4, shading patch 5, last brightening piece 6, following brightening piece 7, diffusion sheet 8, LGP 1, reflector plate 3 and following chase 9.A side at LGP 1 is provided with pcb board 10, and LED11 and FPC (flexible circuit plate) 12 arranged on pcb board 10.
LGP 1 is the integral body that same mould reverse mould is made with framework,
On the framework that fuses with LGP, be provided with the groove structure of carrying backlight assembly.The groove structure mainly is shading patch 5, go up brightening piece 6, brightening piece 7 and the edge 101 of diffusion sheet 8 and the embedded groove of pcb board down, shading patch 5, go up brightening piece 6, brightening piece 7 and diffusion sheet 8 are put into the edge 101 on the LGP 1 successively down.The thickness of edge 101 is preferably 1mm.
On one side of the framework that fuses with LGP, be provided with the groove 100 of the pcb board 10 of carrying LED.Bound edge 300 is arranged on the limit of reflector plate 3, and bound edge 300 gets up the completely encircle of framework, and the bound edge 300 of reflector plate plays the effect of reflection ray and damping.
Following chase 9 gets up from the bottom with the assembly inclusion, and last chase 4 gets up from top with the assembly inclusion.
Claims (5)
1, a kind of back light source structure that does not have the design of plastic cement frame, comprise the framework of LGP, carrying backlight assembly and be located at reflector plate below the LGP, it is characterized in that: described LGP and described framework are the integral body that same mould reverse mould is made, and are provided with the groove structure of carrying backlight assembly on the framework that fuses with LGP.
2, the back light source structure of no plastic cement frame design according to claim 1 is characterized in that: the groove and the edge that are provided with the pcb board of carrying LED on one side of the framework that fuses with described LGP.
3, the back light source structure of no plastic cement frame design according to claim 1, it is characterized in that: on the limit of described reflector plate bound edge is arranged, bound edge gets up the completely encircle of framework.
4, the back light source structure of no plastic cement frame design according to claim 2, it is characterized in that: the thickness of described edge is 0.5mm~2mm.
5, the back light source structure of no plastic cement frame design according to claim 4, it is characterized in that: the thickness of described edge is 1mm.
