Abstract
The utility model discloses a backlight structure of a liquid crystal display module. The backlight structure comprises an upper diffusion sheet (1), an upper brightness enhancement sheet (2), a lower brightness enhancement sheet (3) and a lower diffusion sheet (4), the upper diffusion sheet (1), the upper brightness enhancement sheet (2), the lower brightness enhancement sheet (3) and the lower diffusion sheet (4) are arranged in a stacking mode in sequence, and is characterized by further comprising a light guide plate (5) and a reflector plate (6), wherein the reflector plate (6) is located on the lower surface of the light guide plate (5) and forms an integral structure with the light guide plate (5). The backlight structure effectively avoids the loosing or the displacement of the reflector plate caused by collision or falling, the quality of a display is improved, and user experience is enhanced.
Description
Technical field
The utility model relates to the back light model setting technology field, relates in particular to a kind of backing structure of liquid crystal display module.
Background technology
In the demonstration module of LCD, backing structure has been the parts of main support effect and protective effect.The small-medium size liquid crystal display module backing structure that exists on the market mainly is made of diaphragms such as reflector plate, LGP, diffusion sheet, brightening pieces now.As shown in Figure 1, this structure comprises the last diffusion sheet 1 that is cascading, last brightening piece 2, following brightening piece 3, following diffusion sheet 4, LGP 5, emission sheet 6, each diaphragm all comprises a workspace and a nonclient area, usually paste one deck double faced adhesive tape at its nonclient area, successively each diaphragm is covered on the upper surface of next diaphragm, interfixes thereby make between each diaphragm.But this mode ratio that is adhesively fixed by double faced adhesive tape is easier to become flexible.In the use of product, produce vibrations and very easily cause the loosening of reflector plate or be shifted owing to fall or collide, thereby cause the brightness of supply of back light unit not enough or distribution of light sources is inhomogeneous, cause display display effect variation.
The utility model content
Main purpose of the present utility model is to be influenced the defective of display display effect at the reflector plate in the backing structure that exists in the prior art because shaking the loosening or displacement that causes, and has proposed a kind of reflector plate to be fixed on liquid crystal display module backing structure on the LGP.
A kind of liquid crystal display module backing structure that the utility model provides, comprise the last diffusion sheet that is cascading, go up brightening piece, brightening piece, diffusion sheet down down, also comprise LGP and be positioned at described LGP lower surface and form the reflector plate of integrative-structure with described LGP.
The last diffusion sheet that is cascading in the above-mentioned liquid crystal display module backing structure, last brightening piece, following brightening piece, following diffusion sheet, LGP paste successively.
This reflector plate comprises reflector plate base material and the reflecting material that is plated on this reflector plate base material in the above-mentioned liquid crystal display module backing structure.
The shape and size of this reflector plate base material and the shape and size of this LGP are complementary in the above-mentioned liquid crystal display module backing structure.
This reflector plate base material is plastic material in the above-mentioned liquid crystal display module backing structure.
The beneficial effect of implementing a kind of liquid crystal display module of the utility model backing structure is: the reflector plate at this LGP back side is fixed in the utility model utilization in the one-body molded formation in the back side of LGP, this LGP and reflector plate are merged, form integrative-structure.The product that constitutes when this backing structure falls or when collide, the vibrations of generation can not make reflector plate take place loosening or displacement, more can not influence the display effect of display, have promoted the quality of display, enhancing user experience.
Description of drawings
Below in conjunction with drawings and Examples a kind of liquid crystal display module of the utility model backing structure is described further, in the accompanying drawing:
Fig. 1 is the liquid crystal module group backlight structure decomposing schematic representation of prior art;
The decomposing schematic representation of the liquid crystal module group backlight structure preferred embodiment that Fig. 2 provides for the utility model;
Fig. 3 is the structural representation of LGP 5 and reflector plate 6 among Fig. 2.
The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, be further elaborated to this use is novel.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to figs. 2 to Fig. 3, the liquid crystal module group backlight structure preferred embodiment schematic diagram that Fig. 2 provides for the utility model.This liquid crystal module group backlight structure comprises the last diffusion sheet 1 that is cascading, last brightening piece 2, following brightening piece 3, following diffusion sheet 4, LGP 5, reflector plate 6.Should go up diffusion sheet 1, went up brightening piece 2, down brightening piece 3, down the shape and size of diffusion sheet 4 all the shape and size with LGP 5 are identical so that the applying closely each other of each diaphragm.Should go up diffusion sheet 1, went up brightening piece 2, down brightening piece 3, diffusion sheet 4, LGP 5 all comprise workspace and nonclient area down, this nonclient area is to be centered around workspace fringe region all around, paste one deck double faced adhesive tape in this inoperative zone, each diaphragm utilizes double faced adhesive tape bonding, the upper surface that is fixed in next diaphragm mutually successively.Last diffusion sheet 1 and following diffusion sheet 4 are formed diffusion sheet, and its role is to provides a uniform area source for LCD; Last brightening piece 2, following brightening piece 3 are formed brightening pieces, and its role is to is cohesion light, strengthens the briliancy of light; LGP 5 is used to LCD that uniform area source is provided.
With reference to figure 3, Fig. 3 is LGP 5 and emission sheet 6 structural representations among Fig. 2.Reflector plate 6 is positioned at the lower surface of LGP 5, and has formed integrative-structure with this LGP 5.This reflector plate 6 comprises reflector plate base material 61 and the reflecting material that is plated on this reflector plate base material 61.Adopt integrated mode to form to be fixed in the reflector plate base material 61 of these LGP 5 lower surfaces at the lower surface of this LGP 5, both merge, and form an integral body.In the present embodiment, preferable one-body molded mode is injection mo(u)lding, concrete implementation step is: during this reflector plate base material 61 of injection mo(u)lding, in the mould of this reflector plate base material 61, put into LGP 5, directly the injection of plastic material forms reflector plate base material 61 on the lower surface of LGP 5, makes this reflector plate base material 61 contact in good condition with this LGP 5, merges, after the cooling, both form a fixedly connected integrative-structure.One-body moldedly also can adopt forming methods such as compression molding, moulding by casting.
These reflector plate base material 61 general plastic materials that adopt are generally Merlon or thermoplastic polyester.This reflecting material is generally silver, also can be according to different other materials that adopt of the requirement of reflectivity.Shape and the size of the shape of this reflector plate base material 61 and size and this LGP 5 are identical, cover LGP 5 fully, so that the reflection more light sources prevents that to LGP 5 light source from leaking, improve the utilization rate of light source.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
