Description
Technical field
The utility model relates to the diaphragm location structure of module backlight, and module backlight and display device with described diaphragm location structure.
Background technology
Module backlight mainly is made up of related devices such as light emitting source, reflector plate, blooming piece, LGP, backboards.It is cohesion light that the blooming piece of tool prism structure mainly acts on, and the optical brightening diaphragm of part type and polaroid collocation can will can't see 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 module backlight, 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 be apart from backboard avris certain distance, as seen it is more to rely on the mode of rivet post positioning film to take up room, and has influenced the development process of the narrow limitization of LCD TV greatly.
Therefore, utility model people's anticipation improves the blooming piece location structure, reduces shared space, diaphragm location as far as possible, reduces module frame occupation space thickness backlight, to play the narrow limit development of the purpose that is conducive to display device narrow limit development, especially LCD TV.
The utility model content
The utility model embodiment 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 utility model embodiment has adopted following technical scheme:
A kind of diaphragm location structure comprises backboard, keeper, reaches diaphragm, on described keeper and the backboard limit portion stile, selects one and is provided with buckle, and another is provided with the draw-in groove suitable with buckle; 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 portion stile, select one and be provided with positioning bar, another is provided with the locating slot suitable with positioning bar.
Preferably, described keeper also is furnished with carriage, is formed with the keeper position of packing between backboard limit portion'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 tongue and is provided with buckle, and described backboard limit portion stile is provided with the draw-in groove suitable with buckle.
Preferably, described bullet tongue is formed on the keeper between two recesses, and keeper also is furnished with carriage, and backboard limit portion'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 portion stile.
Another purpose of the utility model embodiment provides a kind of module backlight with above-mentioned diaphragm location structure, by reducing shared space, diaphragm location, reduce module frame occupation space thickness backlight, to play the purpose that is conducive to display device narrow limit development.
To achieve these goals, embodiment of the present utility model adopts following technical scheme:
Module backlight has a plurality of diaphragm location structures, and the diaphragm location structure that provides in above-described embodiment is provided described diaphragm location structure.
The purpose again of the utility model embodiment provides a kind of display device with above-mentioned module backlight, by reducing shared space, diaphragm location, to play the purpose that is conducive to display device narrow limit development.
To achieve these goals, embodiment of the present utility model adopts following technical scheme:
The module backlight that provides in above-described embodiment is provided display device.
Compared with prior art, above-described embodiment of providing of the utility model 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 utility model, keeper are pasting the inner face of backboard limit portion stile, and the lug boss on the keeper matches with locating hole the diaphragm location, and location structure is finished at the backboard avris, and it is less to take up room.
When diaphragm location structure of the present utility model is applied on module backlight and the display device, diaphragm is positioned at the backboard avris and finishes, it is less to take up room, and has reduced module frame occupation space thickness backlight, 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 not do breach at LGP and dodge, and has effectively simplified the design of module backlight.
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 utility model, keeper is pasting the inner face of backboard limit portion stile, lug boss on the keeper matches with locating hole diaphragm is located, location structure is finished at the backboard avris, and backboard limit portion stile only is to hold up merely, does not have any deformation, the shared space thickness of backboard stile is down to minimum, only be the gauge of stile, thereby reduce module frame occupation space thickness backlight, to play the purpose that is conducive to LCD TV narrow limit development.
On keeper and the backboard limit portion stile, select one and be provided with buckle, another is provided with the draw-in groove suitable with buckle.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 the fractionation of maintenance process again.
On keeper and the backboard limit portion stile, select one and be provided with positioning bar, another is provided with the locating slot suitable with positioning bar.When keeper is installed, can go into the position accurately, improve the precision that keeper is installed, make things convenient for installer's assembling again, and positioning bar matches with locating slot and can effectively prevent the double swerve of keeper.
Keeper configuration carriage makes backboard limit portion's stile and carriage clamp keeper jointly, 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 portion stile.The cooperation of this position projection and breach can further effectively be located diaphragm.
Keeper is made by elastomeric material, and this elastomeric material can be plastic material, 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, as some phenolic aldehyde plastic cement and amino plastic cement.
