Abstract
The utility model provides a kind of mobile phone backlight module of narrow frame, including light guide plate and it is placed in light guide plate one side side is provided and enter the LED light source of light, the LED light source is fixed by the glue frame of the reflector plate of one end, the circuit board of the other end and side, it is characterized in that, the side of the light guide plate is disposed with lower diffusion sheet and brightening piece from the inside to the outside, one end covering of the lower diffusion sheet on circuit boards, is coated with black light-absorption layer on the lower diffusion sheet.The utility model meets mobile phone backlight in relatively narrow frame, and the improvement of hot spot effect before lamp to dock OLED new technologies, is substantially better than common screen in cost.
Description
Technical field
The utility model is related to back light model setting technology fields, and in particular to a kind of mobile phone backlight module for narrow frame.
Background technology
In backlight module docking OLED higher and higher, panel is required for narrow frame design（VA）To LED light-emitting surfaces away from
Less and less from requiring, general narrow frame design can not reach the improvement of existing optics taste effect, be susceptible to hot spot
（hot spot）The problems such as, when panel to the LED light-emitting surfaces distance value of general narrow frame is less than 2.8mm, optical effect processing is just
There are certain difficulty, effect degree of reaching is almost nil when requiring apart from smaller.
Utility model content
For solve the problems, such as in backlight module panel to LED give out light identity distance from it is too small when lamp before optical effect it is poor, this practicality
A kind of mobile phone backlight module of new narrow frame of offer, specific technical solution are as follows：
A kind of mobile phone backlight module of narrow frame including light guide plate and is placed in light guide plate one side and provides side and enter the LED of light
Light source, the LED light source are fixed by the glue frame of the reflector plate of one end, the circuit board of the other end and side, which is characterized in that institute
The side for stating light guide plate is disposed with lower diffusion sheet and brightening piece from the inside to the outside, and one end of the lower diffusion sheet is covered in circuit board
On, black light-absorption layer is coated on the lower diffusion sheet.
Preferably, described circuit board one end is formed with to set up the step of lower diffusion sheet.
Preferably, the brightening piece uses double-layer structure.
From above technical scheme, the utility model meets mobile phone backlight in relatively narrow frame, hot spot effect before lamp
Improve, to dock OLED new technologies, common screen is substantially better than in cost.
Description of the drawings
Fig. 1 is the partial structural diagram of the utility model mobile phone backlight module；
Fig. 2 is amplified lower diffusion sheet assembling schematic diagram.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, it is new this practicality is described in detail
Before the technical solution of each embodiment of type, involved noun and term are explained, in the present specification, title is identical
Or the identical component of label represents similar or identical structure, and it is only limitted to the purpose of signal.
As shown in Figure 1, the mobile phone backlight module include light guide plate 1 and be placed in light guide plate one side provide side enter light
LED light source 2, the LED light source are fixed by the glue frame 5 of the reflector plate 3 of one end, the circuit board 4 of the other end and side, LED light
The light-emitting surface in source is parallel with the plane of incidence of light guide plate.
The side of the light guide plate 1 is disposed with lower diffusion sheet 6 and brightening piece 7 from the inside to the outside, and wherein brightening piece uses
Double-layer structure.Gap of the light source between circuit board and membrane material is projected in order to prevent, and one end of lower diffusion sheet 6 is extended over
On circuit board 4, a coating 61 is formed, so as to shelter from the light source in gap, panel is given out light identity distance to LED in backlight module
From it is too small when, can effectively alleviate hot spot phenomenon, optical effect is poor before avoiding the problem that lamp.
In order to avoid improved structure causes product thickness to change, described 4 one end of circuit board needs to be formed with to take
It sets the step 41 of diffusion sheet, and originally lower will expand secret note removal, using being coated with black light-absorption layer 8 on lower diffusion sheet,
For extinction so that integral thickness is constant.The black light-absorption layer 8 is designed using a kind of black printing, it is desirable that print thickness exists
Within 0.005mm, black can effective extinction or so, be effectively improved light leak, the problems such as bright line, hot spot, thickness requirement exists
Enter the problems such as excessively high appearance interference of optical thickness is bad within 0.005mm in order to prevent.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
New scope is defined, and on the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
In the range of shield.
