Description
Technical field
The utility model relates to comprehensive display screen structure field more particularly to a kind of dust-proof backlights of narrow frame.
Background technique
The rise of screen electronic product comprehensively, it is higher and higher for the width requirement of backing structure frame to directly result in product,
To achieve the effect that narrow frame, existing backing structure has been removed the shading glue of left and right side, limits by spill back board structure
The displacement of internal membrane material is made, the membrane material and backboard two sides at least remain with the gap of 0.1mm, the narrower width of backboard, protection
Film can not be with backboard fixation, and in transport or handling process, product concussion causes to protect UF membrane, foreign matter and dust meeting
From the gap into backlight membrane material, causing display white group, the unequal bad phenomenon of display occur, display effect is seriously affected；Its
Secondary, protective film needs to align in fitting, cumbersome, pad pasting inefficiency.
Utility model content
Protect UF membrane that dust is led to problems such as to enter influence display effect, the utility model to solve above-mentioned backing structure
Devise a kind of dust-proof backlight of narrow frame.
A kind of dust-proof backlight of narrow frame, includes backboard, reflector plate, light guide plate and optical film, and the backboard is integrally in
Spill, is provided with folded up portion, and the reflector plate, light guide plate, optical film are successively stacked in concave shaped space from lower to upper；
Further, protective film is provided on the optical film, the protective film is provided with lengthening part, the lengthening part
Lower section is additionally provided with dustproof part.
Further, the protective film further includes having ontology, and described ontology the right and left is overlapped in folded up portion top.
Further, the lengthening part is set to ontology left and right ends, stretches out in folded up portion outer.
Further, the dustproof part is set to the lower surface of the lengthening part and folded up portion lateral surface is formed by angle
Position.
Further, the thickness of the dustproof part is 1/2 or more of backlight thickness, and is no more than the whole thick of backing structure
Degree increases the bonding area of protective film and backboard, prevents the two from separating, while blocks dust and foreign matter enter.
Further, the dustproof part is fixed on lengthening lower surface by double-sided adhesive, protects convenient for subsequent product assembly
Film removes.
The utility model bring the utility model has the advantages that
Tradition, is only overlapped in the guarantor on backboard folded up portion top by a kind of dust-proof backlight of narrow frame of the utility model design
Cuticula, left and right ends are extended outside the outer of folded up portion, lengthening part are arranged, and paste dustproof part lengthening lower surface, are increased
Protective film is bonded fixed-area with backboard, solves since protective film is separated with backboard and to be asked caused by back plate thickness is narrow
Topic, even if protective film is separated with backboard, the dustproof part also effectively can stop external foreign matter to enter；Secondly, product is being protected
When cuticula is bonded, the dustproof part can be used as aligning structure, increase pad pasting efficiency, when protective film removes, also can be used as hand
Handle is torn, it is more convenient；On the other hand, the dustproof part is bonded fixation using weak viscose glue with the contact surface of folded up portion, more
Add and facilitates removing for protective film in subsequent assembling process.

Specific embodiment
Preferred embodiments of the present invention are described below, those of ordinary skill in the art will be according to described below
It is realized with the relevant technologies of this field, and can be more clearly understood that the innovation and bring benefit of the utility model.
As shown in Figure 1, be conventional narrow frame backlight partial structurtes, include backboard 10, reflector plate 20, light guide plate 30 and
Optical film 40, the backboard 10 are provided with folded up portion 11, whole concave, the reflector plate 20, light guide plate 30, optical film 40 according to
Secondary to be stacked in concave shaped space from lower to upper, the top of the optical film 40 is additionally provided with protective film 50, the protective film
50 the right and lefts are overlapped in 11 top of folded up portion.
The optical film 40 includes diffusion barrier 41, lower brightening piece 42, the upper brightening piece 43 successively stacked from lower to upper, described
Protective film 50 is set on the upper brightening piece 43.
Traditional structure narrow frame backlight usually removes the shading plastic structure of the right and left, passes through to reach narrow frame effect
The concave structure of backboard 10 limits the movement of backlight internal structure, but reflector plate 20, light guide plate 30 and optical film 40 and folding
It rises at least there are the gap of 0.1mm between portion 11, secondly, the narrower width of folded up portion 11, protective film 50 and 10 stationary plane of backboard
Product is smaller, can not fixation, in transport or handling process, product concussion will lead to protective film 50 and optical film 40 or back
10 moment of plate separation, as shown in Figure 1, foreign matter can enter inside backing structure from arrow direction, but not after protective film 50 separates
It is confined to this, display is directly resulted in and white group, the unequal bad phenomenon of display occurs, seriously affect display effect.
As shown in Fig. 2, being the preferred embodiments of the present invention partial structural diagram, in the base of conventional narrow frame backlight
On plinth, the left and right ends of 50 ontology 51 of protective film are extended to outside 11 outer of folded up portion, lengthening part 52 is set, are added described
The angular position that long portion 52 is formed with the folded up portion 11, is arranged dustproof part 60, is entered with blocks dust.
Further, the thickness of the dustproof part 60 is 1/2 or more of backlight thickness, and is no more than the entirety of backing structure
Thickness prevents protective film 50 from separating, stops simultaneously to increase the fixed-area of dustproof part 60 Yu protective film 50 and backboard 10
Dust and foreign matter enter.
Further, the dustproof part 60 is fixed on 51 lower surface of lengthening part by double-sided adhesive.
Further, the dustproof part 60 is bonded with the contact surface of the folded up portion 11 using weak viscose glue, is continued insurance after convenient
Cuticula 50 removes.
Preferably, 60 material of dustproof part can be foam or PET, but not limited to this.
50 ontology of protective film, 51 left and right ends are extended setting lengthening part 52 by the utility model, and are arranged under lengthening part 52
The design of dustproof part 60 increases the fixed-area of protective film 50 Yu backboard 10, solves and leads since 10 thickness of backboard is narrow
The protective film 50 and 10 separation problem of backboard of cause；Backboard 10 and 50 fixing intensity of protective film are being reinforced in the setting of dustproof part 60
Meanwhile efficiently solving the problems, such as that dust enters caused by separating because of protective film 50, even if segregation phenomenon occurs for protective film 50, prevents
Dirt portion 60 also effectively can stop external foreign matter to enter, and simple possible is practical；Secondly, product is carrying out the fitting of protective film 50
When, the dustproof part 60 can be used as aligning structure, increase pad pasting efficiency, when protective film 50 removes, also can be used as tearing hand
Handle, it is more convenient.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that specific embodiment of the present utility model is only limited to these instructions.For the common of the utility model technical field
For technical staff, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, all answers
When being considered as belonging to the protection scope of the utility model.
