Abstract
The utility model discloses a kind of narrow frame backlight module for solving the problems, such as bright border, including：Light guide plate, the diffusion barrier being located on the light guide plate and a secret note, the light guide plate includes light in part and the afterbody with light in part opposition, the secret note are attached to the diffusion barrier and play the effect of extinction close to one end of light guide plate afterbody, the secret note.Secret note material price is cheap, and production cost is low；Secret note easily obtains, and can be produced by row automatic die cutter commonly used in the trade, to the less demanding of machine；To the improvement of backlight module afterbody bright border clearly, while the brightness of backlight module is not interfered with.
Description
Technical field
Backlight module field is the utility model is related to, more particularly to a kind of narrow frame backlight mould for solving the problems, such as bright border
Group.
Background technology
Current mobile phone market is more and more for the use demand of the backlight module of ultra-narrow frame, along with backlight module
Frame it is more and more narrow, the bright border phenomenon of backlight module surrounding is also more and more obvious, and the bright border of backlight module afterbody is especially apparent,
The presence of bright border problem, it more or less can all have influence on the usage experience of user.
The method of the improvement backlight module afterbody bright border used at present is：
1st, the optical film material above the light guide plate in backlight module is assembled by afterbody, so do to change to a certain extent
The problem of kind backlight module afterbody bright border, but there is unstability, bright border problem thoroughly to solve because assembling；
2nd, light guide plate afterbody is processed by shot blasting using polishing machine, but requirement of the method to polishing machine is higher, and
Low production efficiency, production cost is improved indirectly.
Therefore, the prior art is defective, it is necessary to improve.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of narrow frame back of the body for solving the problems, such as bright border
Optical mode group, to improve the bright border problem of backlight module afterbody.
The technical solution of the utility model is as follows：A kind of narrow frame backlight module for solving the problems, such as bright border, including：It is guide-lighting
Plate, the diffusion barrier being located on the light guide plate and a secret note, the light guide plate include light in part and with the light in part pair
Vertical afterbody, the secret note are attached to the diffusion barrier close to one end of light guide plate afterbody.
Further, the material of the secret note is the PET of black.
Further, the thickness of the secret note is no more than 0.02mm, and the thickness of backlight module can be influenceed if more than the thickness
Degree, causes mobile phone integrally thickening.
Further, the width of the secret note is 0.05-0.2mm.
Using such scheme, the utility model is directed to backlight module bottom bright border problem, and black is attached in diffusion barrier one end
PET bars, black PET bars play the effect of extinction, so as to eliminate the bright border of backlight module afterbody.The utility model has as follows
Beneficial effect：
1st, secret note material price is cheap, and production cost is low；
2nd, secret note easily obtains, and can be produced by row automatic die cutter commonly used in the trade, to the less demanding of machine；
3rd, to the improvement of backlight module afterbody bright border clearly, while the brightness of backlight module is not interfered with.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of a in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of narrow frame backlight module for solving the problems, such as bright border, including：
Light guide plate, the secret note 20 of diffusion barrier 10 and one being located on the light guide plate, the light guide plate include light in part and with it is described
The afterbody of light in part opposition, the secret note 20 are attached to the diffusion barrier 10 close to one end of light guide plate afterbody.The secret note 20
Material be black PET, its thickness is no more than 0.02mm, the thickness of backlight module can be influenceed if more than the thickness, is caused
Mobile phone is integrally thickening, and the width of the secret note 20 is 0.05-0.2mm.
Using such scheme, the utility model is directed to backlight module bottom bright border problem, and black is attached in diffusion barrier one end
PET bars, black PET bars play the effect of extinction, so as to eliminate the bright border of backlight module afterbody.The utility model has as follows
Beneficial effect：
1st, secret note material price is cheap, and production cost is low；
2nd, secret note easily obtains, and can be produced by row automatic die cutter commonly used in the trade, to the less demanding of machine；
3rd, to the improvement of backlight module afterbody bright border clearly, while the brightness of backlight module is not interfered with.
Preferred embodiment of the present utility model is these are only, is not limited to the utility model, it is all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
