Description
Technical field
The present invention relates to the technical field of display, more particularly, to a kind of structure of warpage and aobvious of preventing after lamp bar aging
Show device.
Background technology
With the development of science and technology, display technology is also being continuously improved.When traditional lamp bar is applied in backlight module
When, lamp bar is usually by double faced adhesive tape on heat sink strip or backboard, since two-sided glue material heat sinking function is bad, after long-time use
It is easy aging, colloidality disappears, and the waste heat be easy to causeing between the lamp bar and the backboard is hoarded, heat extraction is difficult, and in two-sided glue material
Heat Conduction Material is added, the heat sinking function of the two-sided glue material still can not be effectively promoted, further, since the viscosity of two-sided glue material is with temperature
It increases and weakens so that after long-time heat engine, the structural strength between lamp bar and the backboard is insufficient, in planted agent's force effect of backboard
Under, so that the stripping of lamp bar and backboard, cause warpage, showed on flexible displays or TV more strong, influences lamp bar
Enter electrical distance with backboard plate, causes light leakage, to influence the optics macro-effect of display or TV.
Therefore, the existing technology needs to be improved and developed.

Specific implementation mode
For make present invention solves the technical problem that, the technical solution that uses and the technique effect that reaches it is clearer, below
The technical solution of the embodiment of the present invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
The every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
As shown in Figure 1 to Figure 3, Fig. 1 is a kind of schematic diagram preventing the structure of warpage after lamp bar aging provided by the invention.
Fig. 2 is a kind of structural schematic diagram of display device provided by the invention.Fig. 3 is the enlarged diagram at A in Fig. 2.
The present invention provides a kind of structures preventing warpage after lamp bar aging comprising a backboard 3, lamp bar 2 and set on the back of the body
Heat sink strip 1 between plate 3 and lamp bar 2, lamp bar 2 are attached on heat sink strip 1, and lamp bar 2 has one to extend outwardly end, to extension
The end face 34 for stretching end is concordant with heat sink strip 1, and backboard 3 bends inwards at the end that extends outwardly of lamp bar 2 and is provided with a bending part 32,
The inner surface of bending part 32 is connected to the end face 34 at the end that extends outwardly of lamp bar 2.The beneficial effects of the invention are as follows：By that will carry on the back
3 one end of plate, which extends outwardly, is bent to form a bending part 32, and the inner surface of bending part 32 is made to be resisted against the end point of lamp bar 2,
In this way, when aging occurs for 2 uneven heating of lamp bar, when generating internal stress generation warpage, what bending part 32 generated in advance supports power
2 buckling deformation of lamp bar is prevented, that is, limits the degree of freedom of lamp bar 2 so that the illumination effect of lamp bar 2 is ensured, into one
Step ensure that normal display effect.Furthermore it is also easy to make in actual production, it is at low cost, higher economic interests can be generated,
It is easy to marketing application.
Preferably, backboard 3 includes laterally disposed transverse slat 33, is connected to a vertically arranged riser of cross bar end point
31, it bends inwards to be formed with bending part 32 at the upper end of riser 31.During actual production makes, it can be molded by panel beating,
In this way, the production is simple and convenient.
Preferably, the end face 34 of bending part 32 is higher than or the exterior surface 23 of concordant lamp bar 2.In this way, when lamp bar 2 will be sent out
When raw warpage, which can apply the outside end point that an external force supports lamp bar 2, so that it is guaranteed that 2 warpages of lamp bar become
Shape, it is simple and practical in structure.
Preferably, the angled setting of inner surface of bending part 32 and riser 31, angulation is right angle or acute angle.In this way,
When processing, easily controllable angle can generate an inside clamping force to lamp bar 2 in advance, thus support when being arranged at an acute angle
The outside planted agent's force effect of the lamp bar that disappeared 2, thereby further ensures that lamp bar 2 will not buckling deformation.
It, usually will be by the development length and lamp of bending part 32 preferably to ensure that warpage does not occur for lamp bar 2 in actual production
The proportional setting of thickness of item 2, preferably, by ratio between 1.8 to 2.4.For convenience of making selection, usual Set scale is
2.0. namely shown in 32 outwardly extending length value of bending part be twice of lamp bar 2, thus it is ensured that there are one good for the tool of lamp bar 2
Good pre- clamping force has also saved material, and has made the compacter beauty of structure to greatest extent, is additionally favorable for radiating.
The heat generated when working long hours for mode lamp bar 2 can generate thermal expansion to the backboard 3 and heat sink on periphery
Effect, it is preferable that the thickness of heat sink strip 1 is identical as the thickness of the thickness of lamp bar 2 and backboard 3.It is, heat sink strip, lamp
The thickness all same of item and backboard.In this way so that the thermal expansion of various pieces as close as can so expand one together
With shrinking, also just it is less likely to occur the situation of warpage.
Preferably, the middle of the outer surface of lamp bar 2, which extends outwardly, is provided with a boss 22, as shown in Figure 1, the boss 22
Outer end face be higher than bending part 32 end face.Namely in one boss 22 of the outside projection in the centre position of lamp bar main body 21.
By the way that the boss 22 is arranged, the intensity of whole lamp bar 2 is increased so that the thick middle of lamp bar 2, both ends are compared to relatively thin, so not
It is easy warpage, is conducive to the prolonged effective work of lamp bar 2, increases the stability of the lamp bar 2.
In actual production, for reduce product thickness, usually by the thickness of backboard 3 be selected as 0.6mm or 0.8mm or
1.0mm.Certainly, according to the actual needs, can also select other thickness be processed making and it is feasible.
As shown in Figures 2 and 3, the present invention also provides a kind of display devices comprising one kind of any of the above-described prevents
The structure of warpage after lamp bar aging.Since the structure setting is reasonable and compact, when the such structure of display device buying, will be promoted
The overall performance of display device is conducive to marketing.
Preferably, display device is flat-panel monitor 100.It is provided with multiple cards on the backboard 3 of institute's flat-panel monitor 100
Button 5, warping phenomenon is generated after further preventing lamp bar aging.In this way, flat-panel monitor 100 has a wide range of application, market competition
Power is strong.Improved design scheme increases the small bending buckle 5 of indefinite quantity, in the degree of freedom of 2 warpage of lamp bar on backboard 3
It does to limit, influences to enter electrical distance between lamp bar and high tabula rasa because double faced adhesive tape fails so as to improve lamp bar 2, so as to improve complete machine
Optics macro-effect.
It will of course be understood that, it is also feasible when display device is arranged to flexible displays.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and it cannot be construed to limiting the scope of the invention in any way.Based on the explanation herein, the technology of this field
Personnel would not require any inventive effort the other specific implementation modes that can associate the present invention, these modes are fallen within
Within protection scope of the present invention.
