The utility model content
In view of this, main purpose of the present utility model is to provide a kind of glue frame, Backlight source and liquid crystal display device, can avoid liquid crystal panel because of and backlight glue frame between produce extruding, preventing that liquid crystal panel from causing in vibrations or when stressed breaks.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model provides a kind of glue frame, comprises main body, and from the upwardly extending side frame of described main body and the support portion of extending to the inside from main body, also is provided with groove between described side frame and described support portion.
Particularly, described glue frame comprises a plurality of sides, and described groove interconnects along the bearing of trend setting of each side of described glue frame and the described groove on each side.
Particularly, the cross sectional shape of described groove is rectangle, arc, trapezoidal or triangle.
Particularly, the degree of depth of described groove is 0.05mm to 1.0mm.
Particularly, the width of described groove is 0.2mm to 3.0mm.
Particularly, the material of described glue frame is Merlon.
The utility model also provides a kind of backlight, comprises the glue frame that is used for the described backlight module of fixing encapsulation that backlight module and above-described embodiment provide.
The utility model also provides a kind of liquid crystal indicator, comprises the backlight that above-described embodiment provides.
Backlight source and liquid crystal display device of the present utility model, by between the side frame of glue frame and support portion, groove being set, make the contact area of liquid crystal panel and glue frame increase, thereby reduce in vibrations or the stress when stressed, and then be reduced in vibrations or liquid crystal panel breaks when stressed risk, increased anti-shake performance and the reliability of backlight, and had advantages of that technique is simple, cost is low.

The specific embodiment
Fig. 2 is the schematic diagram of liquid crystal indicator in the utility model embodiment.As shown in Figure 2, the utility model provides a kind of liquid crystal indicator, described liquid crystal indicator comprises liquid crystal panel 12 and backlight module 21, glue frame 22, wherein said glue frame 22 comprises a main body 220, have from the upwardly extending side frame 221 of described main body with from the support portion 222 that main body is extended to the inside, also be provided with groove 223 between described side frame 221 and described support portion 222.Described side frame 221 is used for the fixer crystal panel, prevents that liquid crystal panel is subjected to displacement in vibrations or when stressed.Described support portion 222 is used for supporting liquid crystal panel, prevents that the compression weight of liquid crystal panel from causing distortion, affects display effect.Described groove 223 can make liquid crystal panel 12 and the contact area of glue frame 22 increase, thereby reduces in vibrations or the stress when stressed, therefore can reduce the risk that liquid crystal panel breaks, and has increased anti-shake performance and the reliability of backlight.And form groove and do not increase original production procedure, only need to change chamfer angle technique, so the present embodiment has advantages of that also technique is simple, cost is low.
Particularly, backlight for side entering type, as shown in Figure 3, described backlight module 21 can comprise: light source (not shown), LGP 211, optical diaphragm group 212 and reflector plate 213, described light source sends light, enter LGP 211, and reflector plate 213 can be reflected back the light from LGP 211 bottom surface outgoing propagation again LGP 211 again, be evenly distributed in whole LGP 211 by all reflective light and form area source, pass through again optical diaphragm group 212, be transmitted on liquid crystal panel 12.
Particularly, the shape of described groove 223 is not limited only to shown in Fig. 2 or Fig. 3, and the cross sectional shape of described groove 223 can also be rectangle, arc, trapezoidal, triangle etc., is not limited to the shape of described groove in the utility model.In practical application, can select concrete groove shapes according to the realization degree that is easy to of chamfer angle technique.
Particularly, described optical diaphragm group 212 can comprise blooming piece commonly used in the backlight modules such as diffusion sheet, scattering film, prism film, optical brightening diaphragm, is not limited to quantity, kind and the arrangement mode of blooming piece in described optical diaphragm group in the utility model.
Particularly, described light source can be light emitting diode (LED), also can be cathode fluorescent tube (CCFL, Cold Cathode Fluorescent Lamp), is not limited to quantity, kind and the arrangement mode of described light source in the utility model.
In practical application, for the backlight of straight-down negative, can not comprise LGP.
Particularly, the structure of glue frame 22 as shown in Figure 4, glue frame 22 comprises a plurality of sides, described groove 223 interconnects along the bearing of trend setting of each side of described glue frame and the described groove 223 on each side.Particularly, as shown in Figure 2, groove 223 has depth H, and depth H gets final product greater than radius or the rear arc radius that forms of wearing and tearing of technique chamfering.Alternatively, the scope of depth H is between 0.05mm ~ 1.0mm, and depth H is too small, due to the restriction of chamfer angle technique, still has fillet, can't solve the problem that extruding occurs when stressed between glue frame and liquid crystal panel; Depth H is excessive, can have the problem of glue frame undercapacity easy fracture.Groove 223 also has width L, and its scope is between 0.2mm ~ 3.0mm, and width L is too small, and it is larger that chamfer angle technique is implemented difficulty, do not reach the Product Process demand; Width L is excessive, and the border width of display unit also can correspondingly increase, and does not meet product requirement attractive in appearance.
In practical application, the material of glue frame 22 can be Merlon (PC, Polycarbonate), Merlon and glassfiber composite etc., and the material of the frame of glue described in the utility model is not limited to described material.
Although the frame of glue described in the utility model is applied to be not limited to this in reality among the backlight of liquid crystal indicator, for example can also be applied in organic electroluminescence display device and method of manufacturing same.
The above is only preferred embodiment of the present utility model, is not be used to limiting protection domain of the present utility model.
