Abstract
The utility model discloses a kind of backing structures for preventing source ends light leakage, include iron-clad, FPC, light source, and anti-dazzling screen, the iron-clad bottom end are provided with glue position, the FPC realizes fixation by pasting on glue position, the light source is connect with FPC, the anti-dazzling screen is arranged above iron-clad, further includes having photo-shield strip, the photo-shield strip is integral structure, one end is arranged between FPC and anti-dazzling screen, and the other end is arranged along on the outside of iron-clad.By adding a photo-shield strip on the basis of original, it can will solve the problem of bring degumming leakage problem after reducing because of glue position and can also solve that there is preferable practical function because reducing glue position bring structural instability.
Description
Technical field
The utility model relates to design mobile phone backlight field, in particular to a kind of backing structure for preventing source ends light leakage.
Background technique
Currently, with the development of mobile phone technique, it is desirable that mobile phone frame it is more and more narrow, more preferably vision can be obtained
Experience.And frame requires to narrow, the frame of the backlight module in mobile phone is also required to narrower.
And the frame of backlight module narrows at present, one of method solved is by fixed knots some in frame
Structure, which reduce, to narrow, and to reduce required thickness, such as the glue position of iron-clad bottom narrows and becomes smaller.But narrow by glue position
With side it is small after discovery because one of function of glue position itself pastes position as FPC because thickness becomes smaller, institute
Become smaller with the position that FPC is pasted, causes FPC to be easy the accident come unglued when in use and occur, on the one hand influence whole backlight
The stability of structure, it is often more important that, light source can the light transmission from the gap come unglued, there is a phenomenon where light leakages.
Utility model content
Problem to be solved in the utility model is how to solve in the case where backlight module narrow frame, improves entirety
Structural stability, in addition prevent light leakage phenomena occur the problem of.
To solve the above-mentioned problems, the utility model provides a kind of backing structure for preventing source ends light leakage, includes
Iron-clad, FPC, light source and anti-dazzling screen, bottom end is provided with glue position in iron-clad, and FPC is realized on glue position and fixed by pasting, light
Source is connect with FPC, and it further includes having photo-shield strip that anti-dazzling screen, which is arranged above iron-clad, and photo-shield strip is integral structure, one end setting
Between FPC and anti-dazzling screen, the other end is arranged along on the outside of iron-clad.By increasing a photo-shield strip, because photo-shield strip one end is set
It sets between anti-dazzling screen and FPC, the other end is arranged on the outside of iron-clad, and photo-shield strip is overall structure, is equivalent to photo-shield strip for iron
Shell is wrapped up from outer entirety, to occur to occur the phenomenon that all wrapping up the light that inside leaks out, prevent light leakage.
Photo-shield strip is black photo-shield strip.Black photo-shield strip can absorb the light of leakage, reduce the influence of reflection.
Photo-shield strip is arranged between FPC and anti-dazzling screen by way of pasting, and photo-shield strip is by way of pasting along iron
Setting on the outside of shell.By way of pasting, the stability of whole backing structure can be improved, because of the light load-bearing pasted, quite
Not only there was only a fixed point of glue position in FPC, additionally it is possible to by pasting fixation with photo-shield strip, and photo-shield strip itself and screening
Mating plate connection, so enabling to FPC more stable, and the photo-shield strip other end is pasted on the outside of iron-clad, also improves whole
Stability.
Photo-shield strip with a thickness of 0.01 ~ 0.05mm.In the case where the thickness, on the one hand it can guarantee to light leakage absorption
On the other hand effect will not lose the greater for less, lose the effect that narrow side is obtained because reducing glue position,
This has beneficial effect below：
1. structure is simple.By directly increasing photo-shield strip to original structure, can be solved all because reducing the generation of glue position
The problem of.
2. significant effect.The problem of by increasing photo-shield strip, not can solve light leakage suddenly, additionally it is possible to improve integrally-built
Stability can be eliminated because of all problems brought by constriction glue position, be the technology of a highly significant relative to integrated artistic
Progress.
3. low in cost.Increase the low in cost of photo-shield strip, have no need to change technique and overall structure, it is only necessary to increase and hide
Light belt, it is low in cost.
Detailed description of the invention
Fig. 1 is a kind of diagrammatic cross-section for the backing structure for preventing source ends light leakage of the utility model.
Detailed description of the invention：1 is iron-clad, and 2 be glue position, and 3 be FPC, and 4 be anti-dazzling screen, and 5 be photo-shield strip, and 6 be light source, and 7 be two-sided
Glue.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It is easier to be readily appreciated by one skilled in the art with feature, to make apparent define to the protection scope of the utility model.
Embodiment 1
In the present embodiment, the two-sided black glue that photo-shield strip 5 uses, with a thickness of 0.03mm.
The end of iron-clad 1 is provided with the glue position 2 of diminution, is provided with double-sided adhesive 7 above glue position 2, is used for FPC3 and glue position 2
Fixation is pasted, in the lower section of the FPC3 other end, light source 6 is arranged in the front of glue position 2, and light source 6 is connect with FPC3.The top of FPC3
It is provided with anti-dazzling screen 4, one end of photo-shield strip 5 is arranged between FPC3 and anti-dazzling screen 4, because photo-shield strip 5 is two-sided black glue,
FPC3 and anti-dazzling screen 4 can be bonded.
The other end of photo-shield strip 5 stretches out after anti-dazzling screen 4 and coats setting along 1 outer of iron-clad, and pastes and be fixed on iron-clad 1
Outside.
In 6 normal luminous of light source, because FPC3 is connect with glue position 2, and FPC3 is bonded by photo-shield strip 5 and anti-dazzling screen 4
Connection, photo-shield strip 5 are pasted outside iron-clad 1 again, and overall structure is secured, and FPC3 is not easy because shaking or movement cause lower part
Double-sided adhesive 72 generations of coming unglued set, that is, prevent light leakage phenomena.
If double-sided adhesive 72 are set the accident come unglued, the light of light source 6 can be leaked out from the position come unglued, at this point,
Because the cladding setting completely of external photo-shield strip 5 is in 1 outside of iron-clad, light can not leak out again, and by the shading of black
Band 5 is absorbed, to ensure that the whole accident that light leakage will not occur.And it can guarantee when coming unglued light leakage,
The relative position of FPC3 still maintains, and stabilization can still be maintained in whole structure.
The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
Above embodiment can also not depart from the utility model within the knowledge of a person skilled in the art
Various changes can be made under the premise of objective.
