A kind of adhesive frame structure
Technical field
The present invention relates to a kind of liquid crystal panel, be specifically related to a brood lac frame.
Background technology
Liquid panel technique development is maked rapid progress, and specification constantly promotes, and matched module requires also constantly
Promote.The resolution of main flow liquid crystal panel has reached FHD rank at present, and 4K2K product is also shown up prominently.Carrying of resolution
Rise the decline that result in penetrance, therefore backlight illumination is proposed requirements at the higher level.In industry, the means of backlight illumination are improved
Have a lot, such as improve LED luminance, improve light guide plate mesh point minute surface degree etc., but always do not consider to do in terms of glue frame
Promote.In liquid crystal display structure, backlight is mainly used in providing light source for liquid crystal display, and it is generally required to use in backing structure
Glue frame supports light guide plate.When light is advanced in panel with light guide plate, the light arriving glue frame inwall can be reflected back continuation ginseng
Circulating with light, due to the relation of glue frame structure, light is diffuse-reflectance in the reflection of glue frame inwall, removes and enters panel and light guide plate
Outside light, also partition losses is in air borne, or is absorbed by adhesive tape, therefore the light major part arriving glue frame is depleted, it is impossible to
The participation light that remains valid circulates.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that it is bright that one can be effectively improved backlight
The adhesive frame structure of degree.
Technical scheme: a kind of adhesive frame structure, sets at least one inwall that glue frame is relative with liquid crystal panel and light guide plate
Put sunk structure.
Further, described sunk structure be point-like pit or transversely, the groove of longitudinal extension.
Further, described groove runs through the inwall of glue frame or in discontinuously arranging.
Further, sectional dimension and the degree of depth of described sunk structure is 1~10 μm, it is ensured that realize effectively resistance after injection mo(u)lding
The recessed structure of gear reflection light, after injection mo(u)lding, the demoulding easily operates simultaneously, does not results in edge optical and samples intractable problem.
Further preferably, sectional dimension and the degree of depth of described sunk structure is 3~5 μm.
Further, described sunk structure is by protruding injection mo(u)lding corresponding on mould or injection mo(u)lding hot pressing.
Beneficial effect: the diffuse-reflectance in original glue frame inwall plane can be to all angle reflection light, and wherein wide-angle is anti-
Penetrate light can direct losses fall, and the present invention does sunk structure at glue frame inwall, destroys the diffuse-reflectance of original glue frame inwall plane,
Wide-angle in sunk structure diffuses, and can be blocked by sunk structure two ends and again carry out diffuse-reflectance, thus change wide-angle
Reflection light direction, feeds them into panel and continues to participate in light circulation with light guide plate, increase light utilization efficiency, improve backlight illumination;Additionally,
Reduce wide-angle reflection light, the light of module edge loss can be made to reduce, effectively alleviate luminous zone periphery bright border bad.

Detailed description of the invention
Below technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described enforcement
Example.
Embodiment:
Embodiment 1: a kind of backing structure as shown in Figure 1, including panel 1, adhesive tape 2, diaphragm 3, light guide plate 4, reflector plate 5
And glue frame 6.Light guide plate 4 lies on reflector plate 5, and the glue frame 6 that is formed around of light guide plate 4 is coated with the side of light guide plate 4, glue
It is provided with adhesive tape 2 between bottom surface and the reflector plate 5 of frame 6.Multilayer Film 3, the top of diaphragm 3 it is equipped with on the exiting surface of light guide plate 4
It is provided with liquid crystal panel 1, bonding with adhesive tape 2 between panel 1 with glue frame 6 and diaphragm 3.Glue frame 6 and liquid crystal panel 1 and light guide plate 4 phase
Arranging sunk structure on inwall to contact, sunk structure is that diameter 4 μm, cross section are circle as shown in Figure 2 in the present embodiment
Point-like pit, the degree of depth of pit is 5 μm, and the bowl configurations of this shape can reach the effect of effective blocking reflected light, at pit
Interior wide-angle diffuses, and can be lived again carry out diffuse-reflectance by pit edge terminal block, enable light more to assemble concentration
Again putting into diffuse-reflectance and enter panel 1 and light guide plate 4, in Fig. 1, dotted line is incident illumination, it is achieved for effectively reflecting light, and glue frame 6
Edge will not produce leakage problem.
Embodiment 2: on the inwall that glue frame 6 inwall is relative with liquid crystal panel 1, sunk structure is set, the depression knot of the present embodiment
Structure is as it is shown on figure 3, be the groove extended longitudinally, and groove runs through the inwall of glue frame 6 or in discontinuously arranging.The width of groove can be
3 μm, 4 μm, 5 μm or irregular widths, the degree of depth is 4 μm.On inwall, the groove in discontinuously layout is better, can avoid Lou
Light.The bearing of trend of such groove is consistent with stripping direction, therefore the demoulding is more easy to operation during injection mo(u)lding.
Embodiment 3: on the inwall that glue frame 6 inwall is relative with light guide plate 4, sunk structure is set, the sunk structure of the present embodiment
As shown in Figure 4, for the groove extended transversely, groove runs through the inwall of glue frame 6 or in discontinuously arranging on inwall.The width of groove
Degree can be 1 μm, 2 μm, 3 μm, 6 μm, 8 μm, 10 μm, and the degree of depth is 3 μm.
