Description
Technical field
The utility model relates to backlight module field more particularly to a kind of backlight modules for improving light leakage effect.
Background technique
Backlight module is one of key part and component of panel of LCD, and function is well-off brightness and divides
The uniform light source of cloth, enables liquid crystal display panel normally to show image.Diffusion sheet is one of composition of backlight module, major function
It is that a uniform area source is provided for liquid crystal display template.With the arrival in comprehensive screen epoch, the whole world to mobile phone narrow frame or
The demand of ultra-narrow frame is more more and more intense, causes the bright border problem of backlight module to be more and more obvious, drastically influences the view of mobile phone
Feel effect.In view of the above-mentioned problems, existing backlight module is usually to paste shading glue in diffusion sheet tail portion, although in this way, can solve
Certainly backlight module tail portion light leakage bright border problem, but the problem of there is backlight module head bright borders.
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 for improving light leakage effect,
Solve the problems, such as the bright border of backlight module.
The technical solution of the utility model is as follows：There is provided it is a kind of improve light leakage effect backlight module, including diffusion sheet with
And several LED light of light source are provided for backlight module, the LED light is set to the backlight module tail portion, the diffusion sheet tail portion
Post the first black single side adhesive tape, the diffusion sheet head posts the second black single side adhesive tape, among the backlight module head
Equipped with a rectangular recess, the concave bottom two corners are equipped with the first fillet, and recess portion head two corners are equipped with the second fillet, described
Two corners are equipped with third fillet at the top of backlight module, and backlight module bottom two corners are equipped with chamfering, the second black one side glue
Item is arranged along the diffusion sheet head edge, and the third fillet originated on the left of backlight module is terminated at by the recess portion
Third fillet on the right side of backlight module.
Further, the second black single side adhesive tape with a thickness of 0.01-0.012mm, width 0.1-0.3mm.
Further, the size of first fillet is R1.3-R2.4.
Further, the size of second fillet is R2.5-R3.6.
Further, the quantity of the LED light is 16.
Further, the diffusion sheet tail portion is equipped with a protrusion, and the first black single side adhesive tape is affixed on the protrusion.
Using the above scheme, the utility model is by increasing by the second black single side adhesive tape on traditional backlight module head,
It can effectively improve the bright border problem on backlight module head, to improve the quality of backlight module.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model backlight module.
Fig. 2 is the structural schematic diagram of the utility model diffusion sheet.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of backlight module for improving light leakage effect, including diffusion sheet 10
And several LED light 20 of light source are provided for backlight module, the LED light 20 is set to the backlight module tail portion, is backlight mould
Group provides light source, and in the present embodiment, the quantity of the LED light 20 is 16.Post the first black in 10 tail portion of diffusion sheet
Single side adhesive tape 30, the first black single side adhesive tape 30 efficiently solve the problems, such as the bright border of backlight module tail portion, the diffusion sheet 10
Tail portion is equipped with a protrusion, and the first black single side adhesive tape 30 is affixed on the protrusion.Post second in 10 head of diffusion sheet
Black single side adhesive tape 40, the second black single side adhesive tape 40 of setting efficiently solve the problems, such as the bright border on backlight module head.
The backlight module of the utility model is special-shaped backlight module, is equipped with a rectangular recess among the backlight module head
50, mobile phone frame can be done narrow, raising screen accounting for earpiece and camera to be arranged, by the way that recess portion 50 is arranged by the recess portion,
It is preferably experienced to user.The 50 bottom two corners of recess portion are equipped with the first fillet 51, and the size of first fillet 51 is R1.3-
R2.4, the 50 head two corners of recess portion are equipped with the second fillet 52, and the size of second fillet 52 is R2.5-R3.6.The back
Light die set top two corners are equipped with third fillet 53, and backlight module bottom two corners are equipped with chamfering.In production, the second black list
Face adhesive tape 40 cannot be die cut too wide, too wide that the second black single side adhesive tape 40 can be made to enter vision area, the second black single side adhesive tape 40
It can not be die cut too narrow, it is too narrow also not have the effect for improving bright line, therefore manage the width of the second black single side adhesive tape 40
It is the key that be effectively improved backlight module tail portion bright line problem, in the present embodiment, the width of the second black single side adhesive tape 40 is
0.1-0.3mm.The second black single side adhesive tape 40 with a thickness of 0.01-0.012mm, do not interfere with backlight module substantially
Overall thickness.The second black single side adhesive tape 40 is arranged along the diffusion sheet head edge, originates on the left of backlight module
Third fillet 53 terminates at the third fillet 53 on the right side of backlight module by the recess portion 50.
In conclusion the utility model can have by increasing by the second black single side adhesive tape on traditional backlight module head
Effect improves the bright border problem on backlight module head, to improve the quality of backlight module.
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.
