Description
Technical field
The utility model relates to liquid crystal display mode technical group field more particularly to a kind of backlight modules.
Background technique
In existing backlight module, lower bright enhancement film is identical with the shape of diffusion barrier, leads to the bad fixation of diffusion barrier；It leads
Tabula rasa is identical as the size of optical film material side, since the refraction of light be easy to cause side bright line；The left and right sides of lower bright enhancement film
The membrane material ear of protrusion can be set, and glue frame will form recess portion in the position of corresponding membrane material ear and come so that lower bright enhancement film and glue frame
Keep relatively fixed, but the membrane material ear cannot be arranged too big due to narrow frame, this will lead to falls in complete machine
When glue frame can not make membrane material keep it is relatively fixed and generate displacement；And some structures design shading glue and diffusion barrier and under add lustre to
The bond area of film is smaller, there are problems that gluing loosely；The double-sided adhesive of fixed FPC uses Back Word type glue, double due to having before LED light
Face glue stops, and influences the brightness of backlight.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of backlight module.
The technical solution of the utility model is as follows: the utility model provides a kind of backlight module, comprising: glue frame, is led at iron frame
Tabula rasa, diffusion barrier, lower bright enhancement film, upper bright enhancement film, shading glue and FPC component, the diffusion barrier, lower bright enhancement film, upper bright enhancement film and
Shading glue is stacked gradually from bottom to up in the light guide plate light-emitting surface, the diffusion barrier and lower bright enhancement film far from the FPC group
The side of part is concordant with the upper bright enhancement film, is all larger than the upper bright enhancement film in the side length close to the FPC component, described
Lower bright enhancement film and diffusion barrier are close to the FPC component, on one side in being arranged in a staggered manner, the lower bright enhancement film is close to the FPC group
Part is equipped with several recess portions on one side, and the diffusion barrier corresponds to the recess portion equipped with lug boss；The diffusion barrier, lower bright enhancement film and on
Bright enhancement film is concordant in the position on its excess-three side not close to the FPC component and size is greater than the guide-lighting board size.
Further, the quantity of the recess portion is 2, and the recess portion is respectively arranged at the lower bright enhancement film two sides.
Further, the FPC component includes FPC, several LED being welded on the FPC and bonds the FPC
Double-sided adhesive in the glue frame.
Further, the double-sided adhesive corresponds to the LED exit positions and is equipped with opening.
Using the above scheme, the utility model can promote reliability and avoid side bright to the good fixing effect of membrane material
Line occurs, while can promote backlight illumination.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model.
Fig. 2 is the enlarged drawing in Fig. 1 at A.
Fig. 3 is FPC component structure diagram.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
It please refers to Fig.1 to Fig.3, the utility model provides a kind of backlight module, comprising: glue frame 7, is led at iron frame (not indicating)
Tabula rasa (not indicating), diffusion barrier 3, lower bright enhancement film 2, upper bright enhancement film 1, shading glue (not indicating) and FPC component, the diffusion barrier 3,
Lower bright enhancement film 2, upper bright enhancement film 1 and shading glue are stacked gradually from bottom to up in the light guide plate light-emitting surface, the lower bright enhancement film 2
It is flat in the side of the separate FPC component and the upper bright enhancement film 1 to be not provided with membrane material ear, the diffusion barrier 3 and lower bright enhancement film 2
Together, it is all larger than the upper bright enhancement film 2 in the side length close to the FPC component, the lower bright enhancement film 2 and diffusion barrier 3 are leaning on
The nearly FPC component is in be arranged in a staggered manner on one side, and the lower bright enhancement film 2 is several recessed close to being equipped on one side for the FPC component
Portion, the quantity of the recess portion are 2, and the recess portion is respectively arranged at the lower bright enhancement film two sides, and the diffusion barrier corresponds to described recessed
Portion is equipped with lug boss, and when the shading glue is attached on the upper bright enhancement film 1, the shading glue can be by the upper bright enhancement film
1, lower bright enhancement film 2 and diffusion barrier 3 are fixed as relative position, and complete machine is avoided to cause membrane material to shift when falling.The diffusion barrier
3, lower bright enhancement film 2 and upper bright enhancement film 1 in the position on its excess-three side not close to the FPC component concordant and size be greater than it is described
Guide-lighting board size can play the light of the light-guide edge and block, avoid the problem that bright border.
The FPC component includes FPC6, several LED5 being welded on the FPC6 and is bonded in the FPC6 described
Double-sided adhesive 4 in glue frame, the corresponding LED5 exit positions of the double-sided adhesive 4 are equipped with opening 41, can both guarantee adhered area
And effect, and the LED5 light issued can be caused to block to avoid the double-sided adhesive 4.
In conclusion good fixing effect of the utility model to membrane material, can promote reliability and side bright line is avoided to go out
It is existing, while backlight illumination can be promoted.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
