Description
Technical field
The utility model relates to field of liquid crystal display more particularly to a kind of diffusion barriers with camera aperture, backlight module
And liquid crystal display.
Background technique
As the development of smart phone obtains higher screen accounting, mobile phone screen to obtain bigger visible area range
Continue to increase mobile phone edge placement.Due to the limitation of front camera structure, cell phone back light source before this all shorten length with
Avoid camera position.And the full frame effect for being unfavorable for mobile phone by shortening backlight length, therefore study by backlight mould
An aperture is arranged on corresponding position to place camera in group, then mobile phone display screen can be lengthened to mobile phone edge, be designed to ultra-narrow
Frame or Rimless mobile phone, and then diffusion barrier also needs to do corresponding aperture setting.However, aperture is carried out in diffusion barrier, due to light
The reason of transmission, can generate bright line on hole periphery, therefore be not easy to meet the requirements in optical visual effect, it is also necessary to which device to hole carries out
Treatment of details.
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, a kind of diffusion barrier with camera aperture, back are provided
Optical mode group and liquid crystal display meet the placement of front camera, improve screen accounting, while solving the problems, such as bright line, enhancing view
Feel effect.
The technical solution of the utility model is as follows: providing a kind of diffusion barrier with camera aperture, comprising: diffusion barrier is set
The through-hole of close edge and the black glue item being arranged in around the through-hole inside the diffusion barrier, the through-hole setting
In side of the diffusion barrier far from light source.
Further, the through-hole is circular through hole.
Further, the black glue item is annular in shape is set to the through-hole surrounding, or is set in semi-annular shape described
Through-hole is close to the side of lamp source.
Further, the width of the black glue item is 0.25-0.55mm.
Further, further includes: the diffusion barrier is set close to the first shading glue of source ends and is covered in described
The second shading glue on one shading glue.
The utility model also provides a kind of backlight module, including the diffusion barrier as described above with camera aperture, also wraps
Iron frame, reflectance coating, light guide plate and bright enhancement film are included, the iron frame, reflectance coating, light guide plate and bright enhancement film correspond to the through-hole position of diffusion barrier
It sets and is provided with through-hole, the iron frame bends inwards in through hole.
The utility model also provides a kind of liquid crystal display, including backlight module as described above.
Using the above scheme, the utility model does aperture setting by setting through-hole, backlight module on diffusion barrier, and receiving is taken the photograph
As structures such as camera lenses.There is the phenomenon that brightness unevenness because light transmits in bore periphery, to improve optical property, enhancing vision effect
Fruit, being equipped with black glue item around through-hole keeps light uniform.The utility model manufacture craft is simple, and opposite backlight module has
Higher screen accounting makes mobile phone display screen reach ultra-narrow frame or Rimless, and black glue item is set around through-hole and improves optical property, is made
Visual effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic diagram that black glue item is arranged in semi-annular shape.
Fig. 3 is back light module unit structure schematic diagram.
Fig. 4 is the partial enlargement diagram of section B-B through hole in Fig. 3.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1, Fig. 2 are please referred to, the utility model provides a kind of diffusion barrier with camera aperture, comprising: diffusion barrier 10 is set
It is described in 10 inside of diffusion barrier close to the through-hole 11 of edge and the black glue item 12 being arranged in around the through-hole 11
The separate light source side of the diffusion barrier 10 is arranged in through-hole 11, and the position of through-hole 11 corresponds to corresponding mobile phone front camera
Position, the through-hole 11 be used to accommodate camera, to improve screen accounting.
The through-hole 11 is circular through hole, because light transmits, the bright line easy to form around through-hole 11, therefore at through-hole 11 weeks
It encloses and sets black glue item 12, black glue item 12 is annular in shape to be set to 11 surrounding of through-hole, and black glue item 12 plays absorption effects, to disappear
Except bright line phenomenon.
Bright line sometimes is more readily formed close to light source side in through-hole 11, and it is relatively darker far from light source position, at this time will
Black glue item 12 in semi-annular shape be set to the through-hole 11 lean on close to sources side so that far from light source side brightness with lean on dipped beam
The brightness uniformity of source, the phenomenon that avoiding brightness unevenness.Or black glue item 12 is still set as circular, black glue item 12 is close
The width of light source side is set as being greater than the width far from light source side, and the width of general black glue item 12 is 0.25-0.55mm.
Diffusion barrier with camera aperture further include: first shading glue 21 of the diffusion barrier 10 close to source ends is set
And it is covered in the second shading glue 22 on first shading glue 21.First light shield layer, 21 thickness about 0.15mm, is played in bonding
The effect of the fixed membrane material of square shading glue, at the same shut out the light light leakage the phenomenon that, in order to alleviate stress, prevent diffusion barrier fold, therefore
Carry out severing setting.Second light shield layer about 0.01mm is the problem of increasing light mixing distance, reduce socket position bright line light.
Fig. 3, Fig. 4 are please referred to, the utility model also provides a kind of backlight module, including band camera aperture as described above
Diffusion barrier, further include iron frame 30, reflectance coating 40, light guide plate 50 and bright enhancement film 60, the iron frame 30, reflectance coating 40, light guide plate
50 and 11 position of through-hole of the corresponding diffusion barrier 10 of bright enhancement film 60 be provided with through-hole, the iron frame 30 is inwardly curved at through-hole 11
Folding.
The utility model also provides a kind of liquid crystal display, including backlight module as described above.
In conclusion the utility model does aperture setting by setting through-hole, backlight module on diffusion barrier, camera lens are accommodated
First-class structure.There is the phenomenon that brightness unevenness because light transmits in bore periphery, and to improve optical property, enhances visual effect,
Black glue item is equipped with around through-hole keeps light uniform.The utility model manufacture craft is simple, and opposite backlight module is with higher
Shield accounting, so that mobile phone display screen is reached ultra-narrow frame or Rimless, black glue item is set around through-hole and improves optical property, makes vision
It works well.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
