Abstract
The utility model discloses a high-light-transmittance optical diffusion film. The high-light-transmittance optical diffusion film includes a polyethylene substrate layer. The upper surface of the polyethylene substrate layer is sequentially coated with a first polyacrylic resin layer and a second polyacrylic resin layer. The lower surface of the polyethylene substrate layer is coated with a third polyacrylic resin layer. A plurality of uniformly distributed first light scattering particles are embedded into the first polyacrylic resin layer. A plurality of uniformly distributed second light scattering particles are embedded into the second polyacrylic resin layer. A plurality of uniformly distributed third light scattering particles are embedded into the third polyacrylic resin layer. The surface of the polyethylene substrate layer, in contact with the third polyacrylic resin layer, has a plurality of first protrusive parts. The surface of the polyethylene substrate layer, in contact with the first polyacrylic resin layer, has a plurality of second protrusive parts. The high-light-transmittance optical diffusion film has high brightness and optical uniformity, moderate light transmittance and good light transmittance stability, and thus has good application prospects and large market value.
Description
Technical field
The utility model relates to blooming technical field, relates in particular to a kind of high transmission rate optical diffusion.
Background technology
Optical diffusion is used in flat pannel display, LED lamp, makes light produce repeatedly diffraction and refraction via diffusion layer, thereby plays equal light action, allows light display show more evenly soft.When light is when through diffusion layer, will there is the phenomenon of many refractions, reflection and scattering in light, so just caused the effect of optics diffusion, belongs to optical thin film.The effect of existing optical diffusion diffusing light is desirable not to the utmost, likely causes the display quality of final liquid crystal display not good.With the raising of LCD product resolution specification, the requirement of spreading uniformity coefficient for the light of backlight module also improves thereupon, is therefore necessary to provide a kind of evenly better optical diffusion sheet of diffusion of light that makes.
Summary of the invention
The utility model provides a kind of high transmission rate optical diffusion, and this high transmission rate optical diffusion has higher brightness and optics uniformity coefficient, and light penetration moderate and mist degree and light penetration good stability have better application prospect and very big marketable value.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high transmission rate optical diffusion, comprise tygon base material layer, this tygon base material layer upper surface is coated with the first polyacrylic resin layer successively, the second polyacrylic resin layer, described tygon base material layer lower surface is coated with tripropylene acid resin layer, described the first polyacrylic resin layer is embedded in some equally distributed the first astigmatic particles, described the second polyacrylic resin layer is embedded in some equally distributed the second astigmatic particles, described tripropylene acid resin layer is embedded in some equally distributed the 3rd astigmatic particles, the surface that described tygon base material layer contacts with tripropylene acid resin layer has some the first lug bosses, the surface that described tygon base material layer contacts with the first polyacrylic resin layer has some the second lug bosses.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, the diameter of described the 3rd astigmatic particle is less than the diameter of the second astigmatic particle and is greater than the diameter of the first astigmatic particle.
2. in such scheme, the gross thickness of described the first polyacrylic resin layer, the second polyacrylic resin layer is 200 ~ 500 μ m, and the thickness of described tripropylene acid resin layer is 100 ~ 200 μ m.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model high transmission rate optical diffusion, its tripropylene acid resin layer is embedded in some equally distributed the 3rd astigmatic particles, the diameter of described the second astigmatic particle is greater than the diameter of described the first astigmatic particle, described tygon base material layer has some lug bosses with the surface that tripropylene acid resin layer contacts, it is high that optical diffusion film has mist degree, light penetration moderate and mist degree and light penetration good stability, in preparation process, reduce and use solvent, there is higher brightness and optics uniformity coefficient, manufacturing process is simple simultaneously, environmental protection, low price, there is the very big marketable value of better application prospect.
