Description
Technical field
The utility model relates to backlight source domain more particularly to a kind of backlights for improving shading glue sticking effect.
Background technique
Backlight is one of the key part and component of panel of LCD, and function is well-off brightness and distribution
Uniform light source can normally show that image, the illumination effect of backlight imitate the vision for directly influencing liquid crystal display
Fruit.
The main trend of existing market is that high screen accounting is shielded comprehensively, promotes screen accounting using the backlight of ultra-narrow frame.Please
Refering to fig. 1, as subtracting for frame is narrow, shading glue 100 and the bonding area of glue frame 200 are also reduced therewith, and the width of stickup is about
0.3mm can be easily separated during product reliability test and lead to shield interior light leakage, and the lower product of reliability can be by after sale
Move back machine.Determine moreover, the notch that shading glue frontside edge and 200 edge of glue frame are equipped with interval about 0.1mm-0.15mm is used to carry out CCD
Position identification, further reduces the bonding area of shading glue 100 Yu glue frame 200, it is unreliable to cause to be bonded.In order to improve it is such not
Good, current mode is the risk isolated with glue frame 200 of shading glue 100 to be reduced using the shading glue 100 of high viscosity, however hide
The increase of 100 viscosity of optical cement causes product to reprocess difficulty, and 100 higher cost of high viscosity shading glue, and product cost is low, does not have
The market competitiveness.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of backlight for improving shading glue sticking effect
Source.
The technical solution of the utility model is as follows: providing a kind of backlight for improving shading glue sticking effect, comprising: guide-lighting
Plate, the membrane material being bonded with the light guide plate, the glue frame that light guide plate and membrane material are surrounded and shading glue, the glue frame medial surface
With one fixed gap of membrane material interval, shading glue one end is bonded with glue frame, and the other end is bonded with membrane material, shading glue be bonded with glue frame one
Glue frame is sticked at end, and four side of shading glue is equipped with several grooves.
Further, the groove is rectangle, and length is greater than 5mm, and width is no more than 0.1mm.
Further, the shading glue each edge is set there are two groove.
Further, the backlight top center is equipped with a rectangular recess, and the concave bottom two corners are equipped with the first circle
Angle, recess portion head two corners are equipped with the second fillet.
Further, the width that the shading glue is bonded with glue frame is 0.4mm, the width that the shading glue is bonded with membrane material
For 0.3mm.
Further, the membrane material includes diffusion sheet and the brightening piece that is bonded with the diffusion sheet.
Using the above scheme, the utility model has the following beneficial effects:
1, the edge of shading glue and the edge of glue frame be there are gap, so that the shading glue width Nian Jie with glue frame increases,
It is bonded stronger, to prevent shading glue when reliability test from separating with glue frame, reduces the risk of light leakage in shielding；
2, for the utility model without the shading glue of high viscosity, material loss is reprocessed in reduction, while reducing cost, is improved
Cost performance；
3, multiple grooves are designed on four side of shading glue, solves the problems, such as that CCD para-position identifies.
Detailed description of the invention
Fig. 1 is the structural schematic diagram in traditional backlight source.
Fig. 2 is the front view of the utility model.
Fig. 3 is the side view of the utility model.
Fig. 4 is the enlarged diagram of the part c in Fig. 2.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 3, the utility model provides a kind of backlight for improving shading glue sticking effect, comprising: light guide plate 1,
The membrane material 2 that is bonded with the light guide plate 1, the glue frame 3 that light guide plate 1 and membrane material 2 are surrounded and shading glue 4.In the glue frame 3
Side and membrane material 2 are spaced a fixed gap, and 4 one end of shading glue is bonded with glue frame 3, and the other end is bonded with membrane material 2, and the membrane material 2 is wrapped
The brightening piece for including diffusion sheet and being bonded with the diffusion sheet.Stick glue frame 3, i.e. shading in one end that shading glue 4 is bonded with glue frame 3
The coincident at the edge of glue 4 and glue frame 3, the width a that the shading glue 4 be bonded with glue frame 3 are 0.4mm, the shading glue 4 and
The width b that membrane material 2 is bonded is 0.3mm.Compared to traditional design, the area pasted between shading glue 4 and glue frame 3 increases, and glues
Patch width about increases 0.1mm, it is therefore not necessary to using highly viscous shading glue 4, using the shading glue 4 of common viscosity.
Please refer to Fig. 2 to Fig. 4, due to 4 edge of shading glue and 3 coincident of glue frame, although increase shading glue 4 with
The bonding area of glue frame 3, but 3 edge of glue frame is covered by shading glue 4, during carrying out other production and processings, CCD can not
