Abstract
The utility model discloses a kind of back light source structure that side is mounted, include: iron frame side wall, the FPC on the iron frame side wall, be welded on the FPC far from the LED light on described this one side of iron frame side wall, the incidence surface of the top face light guide plate of the LED light is arranged, and the LED light is to push up illuminated LED.The size that the mounted back light source structure design in the utility model the utility model side passes through reduction LED light, LED light is welded on FPC one side, the another side FPC is attached to iron frame side wall by double faced adhesive tape, greatly shortens the size of lower frame, screen accounting is promoted, the visual experience of product is improved.
Description
Technical field
The utility model relates to back light model setting technology field more particularly to a kind of back light source structures that side is mounted.
Background technique
Smart phone starts courageously to imagine in shape and visual enjoyment currently on the market, and height screen accounting abnormally-structured is opened
Beginning is increasingly favored by intelligent mobile phone terminal and consumer.Height screen accounting designs the premise constant in traditional mobile phone shape
Under, screen accounting is increased, reduces mobile phone frame up and down, gives the better visual experience of consumer.
As shown in Fig. 1 light-source structure, LED chip lamp is welded on FPC, LED chip is rectangle, and LED chip has top to shine
Two kinds of light-emitting surfaces of face d and side light-emitting surface c.
Traditional structure screen accounting is larger at present, and especially lower edge is limited and LED shape width and conventional attachment structure
Screen accounting and utilization rate are lower.It is so that its side light-emitting surface c is shone the encapsulation of LED chip 30 in the prior art such as Fig. 2, exists at this time
Double-sided adhesive 50 is pasted in the opposite side that FPC20 welds LED chip 30, and FPC20 is attached on iron frame 10 by double-sided adhesive 50, at this time LED chip
30 are fixed on the incidence surface of light guide plate 40, and against 40 incidence surface of light guide plate, the length of light path a is 30 side light-emitting surface c of LED chip
1.73mm, light path are too long；And the width b of corresponding backlight module lower frame is 3.32mm wider.
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 back light source structure that side is mounted.
The technical solution of the utility model is as follows: the utility model provides a kind of back light source structure that side is mounted, comprising: iron
Frame side wall, the FPC on the iron frame side wall, the FPC is welded on far from the LED on described this one side of iron frame side wall
Lamp, the incidence surface setting of the top face light guide plate of the LED light, the LED light is to push up illuminated LED.
The FPC is attached on the iron frame side wall.
The FPC is invested on the iron frame side wall using double faced adhesive tape.
The model 1404 for the LED chip that the LED light uses.
The double-sided adhesive is no substrate double-sided adhesive.
Foam double-faced adhesive is equipped between the FPC and the iron frame side wall.
Using the above scheme, the mounted back light source structure design in the utility model side, will by the size of reduction LED light
LED light is welded on the one side of FPC, and the another side FPC is attached to iron frame side wall by double faced adhesive tape, is greatly shortened following
The size of frame promotes screen accounting, improves the visual experience of product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of LED chip encapsulation in traditional backlight source；
Fig. 2 is the structural schematic diagram of traditional backlight module；
Fig. 3 is the structural schematic diagram of the mounted back light source structure in the utility model side.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 3, the utility model provides a kind of back light source structure that side is mounted, comprising: iron frame side wall 1 is set to institute
It states the FPC2 on iron frame side wall 1, be welded on the FPC2 far from the LED light 3 on described this one side of iron frame side wall 1, the LED
The incidence surface of light guide plate 4 described in the top face of lamp 3 is arranged, and the LED light 3 is to push up illuminated LED.It is illuminated using pushing up
LED light is welded on the FPC2, this face paste that the FPC2 does not weld LED light is attached on the iron frame side wall 1, this
It designs light path a and 0.71mm is substantially reduced to by conventional 1.73mm, substantially reduce light path；The width b of lower frame is from conventional
3.32mm shortens to 1.55mm, greatly shortens frame, and screen accounting is substantially improved, and gives the better visual experience of consumer.It adopts
The risk of lamp fracture, also, the model 1404 of the LED chip of the use of the LED light 3, institute are also reduced with the mode that side is pasted
The number for stating LED light 3 increases compared with the LED light number in traditional backlight source, is conveniently adjusted effect, while promoting brightness.
Further, double-sided adhesive 5 is equipped between the FPC2 and the iron frame side wall 1, it will be described by the double-sided adhesive 5
FPC2 is bonded on the iron frame side wall 1, and securely, thickness is thin, improves the visual experience of product for bonding.Specifically, this implementation
Double-sided adhesive 5 described in example is no substrate double-sided adhesive, and no substrate double-sided adhesive does not use substrate, energy in the case where not influencing peeling force
Enough further decrease integral thickness.
As alternative another embodiment, foam double-faced adhesive is equipped between the FPC and the iron frame side wall, it is described
Foam double-faced adhesive can either play the role of bonding, and can play buffering.
In conclusion the utility model side it is mounted back light source structure design by reduce LED light size, by LED light
It is welded on FPC one side, the another side FPC is attached to iron frame side wall by double faced adhesive tape, greatly shortens the ruler of lower frame
It is very little, screen accounting is promoted, the visual experience of product is improved.
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.
