Abstract
A kind of high transmittance haze optical diffusion, including PET base material layer, the one side of the PET base material layer are provided with transparent resin layer, and spherical PU hollow granules are embedded with described transparent resin layer, and part PU hollow granules are exposed to outside described transparent resin layer.PU hollow granules in optical diffusion be distributed in transparent resin layer inside and partial denudation in outside transparent resin layer, light has the optical effects such as scattering, diffraction, refraction and reflection through diffusion membrane process, obtains the optical diffusion of high transmittance haze.
Description
Technical field
It the utility model is related to a kind of optical diffusion.
Background technology
Liquid crystal display device needs to provide light source, backlight mould by backlight module because liquid crystal display panel can not light in itself
Group according to the location of lamp bead is divided into full run-down type and side enters type, and the blooming piece in backlight module includes reflectance coating, diffusion barrier
And brightness enhancement film.Above light guide plate, existing meaning is to correct light angle diffusion barrier sheet therein, increases light radiating surface
Product, makes module turn into good evenness, chroma stability, 2 high secondary light sources of briliancy.
Existing optical diffusion is also unable to reach the requirement of haze high transmittance.
The content of the invention
In order to overcome the above-mentioned deficiency of existing optical diffusion, the utility model provides a kind of high transmittance haze optics
Diffusion barrier.
The technical scheme in the invention for solving the technical problem is：A kind of high transmittance haze optical diffusion, bag
PET base material layer is included, the one side of the PET base material layer is provided with transparent resin layer, spherical PU is embedded with described transparent resin layer
Hollow granule, part PU hollow granules are exposed to outside described transparent resin layer.
Further, the external diameter of the PU hollow granules is 5-10 μm, and the internal diameter of the PU hollow granules is 1-4 μm.
Further, the 60% of the PU hollow granules is located in described transparent resin layer, and the 40% of the PU hollow granules
Expose to outside described transparent resin layer；PU hollow granules in transparent resin layer are evenly distributed in the transparent resin layer, outside
The PU hollow granules being exposed to outside described transparent resin layer are evenly distributed in the transparent resin layer surface.
Further, the another side of described PRT substrate layers is provided with anti scuffing resin bed.
Further, the thickness of the transparent resin layer is 1.5 times of PU hollow granule external diameters.
The beneficial effects of the utility model are：PU hollow granules in optical diffusion are distributed in the interior of transparent resin layer
In outside transparent resin layer, light has scattering, diffraction, refraction and the optics such as reflection to imitate through diffusion membrane process for portion and partial denudation
Fruit, obtain the optical diffusion of high transmittance haze.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Reference picture 1, a kind of high transmittance haze optical diffusion, including PET base material layer 1, the PET base material layer 1
Transparent resin layer 2 is simultaneously provided with, spherical PU hollow granules 3, part PU hollow granules 3 are embedded with described transparent resin layer 2
Expose to outside described transparent resin layer.PU hollow granules 3 in optical diffusion are distributed in the inside and portion of transparent resin layer 2
Divide and be exposed to outside transparent resin layer 2, light has the optical effects such as scattering, diffraction, refraction and reflection, acquisition through diffusion membrane process
The optical diffusion of high transmittance haze.
In this implementation, the external diameter of the PU hollow granules 3 is 5-10 μm, and the internal diameter of the PU hollow granules 3 is 1-4 μm,
The thickness of the transparent resin layer 2 is 1.5 times of PU hollow granule external diameters, the PU hollow granules 3 60% positioned at described saturating
In ming tree lipid layer, the 40% of the PU hollow granules 3 exposes to outside described transparent resin layer 2, and the PU in transparent resin layer is hollow
Uniform particle is distributed in the transparent resin layer, and the PU hollow granules exposed to outside described transparent resin layer are evenly distributed on this
In transparent resin layer surface.Possess the optical diffusion of above-mentioned condition, its transmitance can be lifted further with mist degree, transmitance with
Mist degree can reach more than 85%.
In the present embodiment, the another side of described PRT substrate layers is provided with anti scuffing resin bed 4.
