Description
Technical field
The present invention relates to the diaphragm location structure of backlight module, and backlight module and the display device with described diaphragm location structure.
Background technology
Backlight module is mainly comprised of related devices such as light emitting source, reflector plate, blooming piece, LGP, backboards.The blooming piece Main Function of tool prism structure is cohesion light, and the optical brightening diaphragm of part type and polaroid collocation can be by seeing through polarised light reflection, recovery, the recycling of polarizer, to improve the effective rate of utilization of light.This just requires blooming piece location and installation accurate, and installation accuracy is had relatively high expectations.
At present, in the assembling process of backlight module, the location of blooming piece is that the rivet post on backboard completes, the firmness of rivet post in order to guarantee that it is combined with backboard, need to be apart from backboard avris certain distance, the mode of visible dependence rivet post positioning film takes up room more, has affected greatly the development process on the narrow limit of LCD TV.
Therefore, inventor's anticipation improves blooming piece location structure, reduces as far as possible diaphragm and locates shared space, reduces the space thickness that backlight module frame takies, to play the narrow limitization development of the object, the especially LCD TV that are conducive to the narrow limitization development of display device.
Summary of the invention
The embodiment of the present invention is to provide a kind of diaphragm location structure, to solve diaphragm in prior art, relies on rivet post to locate the more technical problem that takes up room.
In order to solve the problems of the technologies described above, the embodiment of the present invention has adopted following technical scheme:
A diaphragm location structure, comprises backboard, keeper and diaphragm, on described keeper and backboard limit portion stile, selects one and is provided with buckle, is provided with the draw-in groove suitable with buckle on another; On described keeper, there is lug boss, on diaphragm, there is the locating hole suitable with described lug boss, the diaphragm location of being matched with lug boss by locating hole.
Preferably, on described keeper and backboard limit portion stile, select one and be provided with positioning bar, on another, be provided with the locating slot suitable with positioning bar.
Preferably, described keeper is also furnished with bracket, is formed with keeper and packs position between backboard limit portion's stile and bracket.
Preferably, described keeper is made by elastomeric material.
Preferably, described keeper in the form of sheets, has bullet tongue on keeper, plays on tongue and is provided with buckle, on described backboard limit portion stile, is provided with the draw-in groove suitable with buckle.
Preferably, described bullet tongue is formed on keeper between two recesses, and keeper is also furnished with bracket, and backboard limit portion's stile and bracket are clamped keeper jointly, and on bracket, the position corresponding with playing tongue has and dodge groove.
Preferably, the part that described diaphragm has a locating hole is projection laterally, on backboard limit portion stile, has the breach suitable with described projection.
Another object of the embodiment of the present invention is to provide a kind of backlight module with above-mentioned diaphragm location structure, by reducing diaphragm, locate shared space, reduce the space thickness that backlight module frame takies, to play the object that is conducive to the narrow limitization development of display device.
To achieve these goals, embodiments of the invention adopt following technical scheme:
Backlight module, has a plurality of diaphragm location structures, and the diaphragm location structure providing in above-described embodiment is provided described diaphragm location structure.
An object again of the embodiment of the present invention is to provide a kind of display device with above-mentioned backlight module, by reducing diaphragm, locates shared space, to play the object that is conducive to the narrow limitization development of display device.
To achieve these goals, embodiments of the invention adopt following technical scheme:
Display device, the backlight module providing in above-described embodiment is provided.
Compared with prior art, above-described embodiment tool provided by the invention has the following advantages:
Than the diaphragm locate mode that adopts rivet post, the firmness of rivet post in order to guarantee that it is combined with backboard, must be apart from backboard avris certain distance, cannot close backboard avris.Diaphragm location structure of the present invention, keeper is pasting the inner face of backboard limit portion stile, and the lug boss on keeper matches with locating hole diaphragm location, and location structure completes at backboard avris, takes up room less.
When diaphragm location structure of the present invention is applied on backlight module and display device, diaphragm is positioned at backboard avris and completes, and takes up room less, has reduced the space thickness that backlight module frame takies, and to LCD TV, positive facilitation is played in narrow limitization development.The structural design of diaphragm below LGP needn't be considered the interference that the keeper of diaphragm brings, and in spatial distribution, LGP is positioned at the inner side of each keeper, need on LGP, not do breach and dodge, and has effectively simplified the design of backlight module.
Than backboard stile is bent to form to tongue, the mode with tongue to diaphragm location in order to form tongue moulding, certainly will need to increase the shared space thickness of backboard stile on stile, is unfavorable for the object of the narrow limitization development of LCD TV.Diaphragm location structure of the present invention, keeper is pasting the inner face of backboard limit portion stile, lug boss on keeper matches diaphragm is located with locating hole, location structure completes at backboard avris, and backboard limit portion stile is only to hold up merely, without any deformation, the shared space thickness of backboard stile is down to minimum, be only the gauge of stile, thereby reduce the space thickness that backlight module frame takies, to play the object that is conducive to the narrow limitization development of LCD TV.
On keeper and backboard limit portion stile, select one and be provided with buckle, on another, be provided with the draw-in groove suitable with buckle.Adopt this convenient structure being connected of buckle and draw-in groove, guaranteed the reliability that keeper is connected with backboard, facilitated again the fractionation of maintenance process.
On keeper and backboard limit portion stile, select one and be provided with positioning bar, on another, be provided with the locating slot suitable with positioning bar.When keeper is installed, can enter accurately position, improve the precision that keeper is installed, facilitate again installer's assembling, and positioning bar matches with locating slot and can effectively prevent the double swerve of keeper.
Keeper configuration bracket, makes backboard limit portion's stile and bracket jointly clamp keeper, and the movement of restriction keeper improves the stability of keeper to diaphragm location.On bracket, the position corresponding with playing tongue has and dodges groove, to the reserved certain deformation space of keeper, in the time of need to dismantling keeper, keeper gently pressed to dodging groove direction, and the buckle of top and draw-in groove depart to realize to be disassembled.
The part that diaphragm has a locating hole is projection laterally, on backboard limit portion stile, has the breach suitable with described projection.The cooperation of this position projection and breach, can further carry out effective location to diaphragm.
Keeper is made by elastomeric material, and this elastomeric material can be plastic material, as conventional raw materials such as PE, PP, PVC, PS, ABS, PMMA, POM, PC or PA; Also can be the synthetic resin of heat hardening, as some phenolic aldehyde plastic cement and amino plastic cement.
