Abstract
The utility model discloses a kind of diffusion barrier, belong to LCD backlight technical field, including PET base material, the diffusion layer comprising diffusion particle it is coated with on the one side of described base material, the particle diameter of described diffusion particle is 40 60um, base material is coated with antistatic layer on the another side of described diffusion layer phase pair, and described antistatic layer is formed the micro structure diffusion point of convex dome-type.
Description
Technical field
This utility model belongs to LCD backlight technical field, is specifically related to a kind of diffusion barrier.
Background technology
Backlight key component includes light source, light guide plate and all kinds of blooming, and blooming mainly includes reflectance coating, diffusion barrier
And brightness enhancement film, wherein the light of injection from light guide plate can uniformly be spread by diffusion barrier, and to form uniform area light source, it is former
Reason is the diffusion layer that light passes through using PET as base material, passes so that light reflects, instead from the medium that refractive index is different
Penetrating and scatter, reach the effect of optics diffusion, traditional diffusion barrier manufacture method is to be mixed in bonding agent by scattering particles,
In transparent PET base material, coating is mixed with diffusion particle bonding agent, is formed through high temperature or UV photocuring, this traditional producer
Formula, needs to use substantial amounts of organic solvent, has certain harm to environment, and scattering particles bonds to through subsequent technique simultaneously
On bright base material, at backlight module after vibration-testing, hot and humid test, the scattering particles existence at the diffusion barrier back side comes off
Risk, causes the bad phenomenon of scratch light guide plate to occur, and reduces the yield of backlight module.
Utility model content
The purpose of this utility model is to provide a kind of diffusion barrier, and this diffusion barrier will not be in vibration towards the side of light guide plate
Test, hot and humid test damage light guide plate.
Technical solutions of the utility model one diffusion barrier, including PET base material, the one side of described base material is coated with and comprises
The diffusion layer of diffusion particle, the particle diameter of described diffusion particle is 40-60um, on the another side of base material and described diffusion layer phase pair
It is coated with antistatic layer, described antistatic layer is formed the micro structure diffusion point of convex dome-type.
Preferably, a kind of diffusion barrier described in the utility model, the particle diameter of described micro structure diffusion point is 5-10um.
This utility model technology beneficial effect:
The micro structure that is provided with light guide plate described in technical solutions of the utility model spreads when the side put uses towards leaded light
Plate, micro structure diffusion point attachment is stable, does not comes off in vibration-testing, hot and humid test, it is to avoid damage light guide plate, improves
The efficiency of backlight module.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
For ease of skilled artisan understands that technical solutions of the utility model, new to this practicality in conjunction with Figure of description
Type technical scheme is described further.
As it is shown in figure 1, diffusion barrier described in the utility model, including PET base material 1, the one side of described base material 1 is coated with
Having the diffusion layer 2 comprising diffusion particle, the particle diameter of described diffusion particle is 40-60um, and base material 1 is relative with described diffusion layer 2
It is coated with antistatic layer 3 on another side, described antistatic layer 3 is formed the micro structure diffusion point 4 of convex dome-type.
The particle diameter of described micro structure diffusion point 4 is 5-10um.
This diffusion barrier is had the side of micro structure diffusion point 6 and is used as the back side, the side directly imprinted by mould in use
Formula forms the micro structure diffusion point 6 of homogeneous convex dome-type on antistatic layer 5, and its attachment is stable, can be the most right
Light is diffused, and while reaching uniformly to go out light purpose, does not haves and comes off and the situation of scratch light guide plate.
Utility model is exemplarily described by technical solutions of the utility model above in conjunction with accompanying drawing, it is clear that this practicality
Novel implementing is not subject to the restrictions described above, and carries out with technical scheme as long as have employed method of the present utility model design
Various unsubstantialities improve, or the most improved design by utility model and technical scheme directly apply to other occasion,
All within protection domain of the present utility model.
