Description
Technical field
The present invention relates to the diaphragm location structure of backlight module, and backlight module and display device with described diaphragm location structure.
Background technology
Backlight module mainly is 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 with seeing through polarised light reflection, recovery, the recycling of polarizer, to improve the effective rate of utilization of light.This just requires the 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 the backboard is finished, the firmness of rivet post in order to guarantee that it is combined with backboard, need to be apart from backboard avris certain distance, as seen rely on the mode of rivet post positioning film to take up room more, affected greatly the development process on the narrow limit of LCD TV.
Therefore, inventor's anticipation improves the blooming piece location structure, reduces as far as possible shared space, diaphragm location, reduces the space thickness that the backlight module frame takies, to play the narrow limit development of the purpose that is conducive to display device narrow limit development, especially LCD TV.
Summary of the invention
The embodiment of the invention provides a kind of diaphragm location structure, and diaphragm relies on the rivet post to locate the more technical problem that takes up room in the prior art to solve.
In order to solve the problems of the technologies described above, the embodiment of the invention has adopted following technical scheme:
A kind of diaphragm location structure comprises backboard, keeper, reaches diaphragm, on described keeper and the backboard limit section stile, selects one and is provided with buckle, is provided with the draw-in groove suitable with buckle on another; Have lug boss on the described keeper, have the locating hole suitable with described lug boss on the diaphragm, diaphragm is by the locating hole location of matching with lug boss.
Preferably, on described keeper and the backboard limit section stile, select one and be provided with positioning bar, be provided with the locating slot suitable with positioning bar on another.
Preferably, described keeper also is furnished with carriage, is formed with the keeper position of packing between backboard limit section's stile and carriage.
Preferably, described keeper is made by elastomeric material.
Preferably, described keeper has the bullet tongue in the form of sheets on the keeper, plays on the tongue and is provided with buckle, is provided with the draw-in groove suitable with buckle on the described backboard limit section stile.
Preferably, described bullet tongue is formed on the keeper between two recesses, and keeper also is furnished with carriage, and backboard limit section's stile and carriage are clamped keeper jointly, and the position corresponding with playing tongue has and dodge groove on the carriage.
Preferably, the part that described diaphragm has a locating hole is projection laterally, has the breach suitable with described projection on the backboard limit section stile.
Another purpose of the embodiment of the invention provides a kind of backlight module with above-mentioned diaphragm location structure, by reducing shared space, diaphragm location, reduce the space thickness that the backlight module frame takies, to play the purpose that is conducive to display device narrow limit development.
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 that provides in above-described embodiment is provided described diaphragm location structure.
An again purpose of the embodiment of the invention provides a kind of display device with above-mentioned backlight module, by reducing shared space, diaphragm location, to play the purpose that is conducive to display device narrow limit development.
To achieve these goals, embodiments of the invention adopt following technical scheme:
The backlight module that provides in above-described embodiment is provided display device.
Compared with prior art, above-described embodiment provided by the invention has following advantage:
Than the diaphragm locate mode that adopts the 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, can't close backboard avris.Diaphragm location structure of the present invention, keeper are pasting the inner face of backboard limit section stile, and the lug boss on the keeper matches with locating hole the diaphragm location, and location structure is finished at the backboard avris, takes up room less.
When diaphragm location structure of the present invention was applied on backlight module and the display device, diaphragm was positioned at the backboard avris and finishes, and took up room less, had reduced the space thickness that the backlight module frame takies, and positive facilitation is played in the development of narrow limit to LCD TV.The structural design of diaphragm below LGP needn't be considered the interference that the keeper of diaphragm brings, and LGP is positioned at the inboard of each keeper on spatial distribution, need to not do breach at LGP and dodge, and has effectively simplified the design of backlight module.
Than the backboard stile is bent to form tongue, with the mode of tongue to the diaphragm location, on stile, in order to form the tongue moulding, certainly will need to increase the shared space thickness of backboard stile, be unfavorable for the purpose of LCD TV narrow limit development.Diaphragm location structure of the present invention, keeper is pasting the inner face of backboard limit section stile, lug boss on the keeper matches with locating hole diaphragm is located, location structure is finished at the backboard avris, and backboard limit section stile only is to hold up merely, without any deformation, the shared space thickness of backboard stile is down to minimum, only be the gauge of stile, thereby reduce the space thickness that the backlight module frame takies, to play the purpose that is conducive to LCD TV narrow limit development.
On keeper and the backboard limit section stile, select one and be provided with buckle, be provided with the draw-in groove suitable with buckle on another.Adopt this convenient structure that is connected of buckle and draw-in groove, namely guaranteed the reliability that keeper is connected with backboard, made things convenient for again the fractionation of maintenance process.
On keeper and the backboard limit section stile, select one and be provided with positioning bar, be provided with the locating slot suitable with positioning bar on another.When keeper is installed, can enter accurately the position, improve the precision that keeper is installed, make things convenient for again installer's assembling, and positioning bar matches with locating slot and can effectively prevent the double swerve of keeper.
Keeper configuration carriage makes backboard limit section's stile and carriage jointly clamp keeper, and the movement of restriction keeper improves keeper to the stability of diaphragm location.The position corresponding with playing tongue has and dodges groove on the carriage, reserves certain deformation space to keeper, when needing the dismounting keeper, keeper gently pressed to dodging the groove direction, and the buckle of top and draw-in groove break away to be realized disassembling.
The part that diaphragm has a locating hole is projection laterally, has the breach suitable with described projection on the backboard limit section stile.The cooperation of this position projection and breach can further be carried out effective location to diaphragm.
Keeper is made by elastomeric material, and this elastomeric material can be plastic material, such as raw materials commonly used such as PE, PP, PVC, PS, ABS, PMMA, POM, PC or PA; Also can be the synthetic resin of heat hardening, such as some phenolic aldehyde plastic cement and amino plastic cement.
