Abstract
The utility model discloses an anti-scratch brightness enhancement film. The anti-scratch brightness enhancement film includes a first polyethylene base layer, a second polyethylene base layer and a transparent resin layer; the transparent resin layer is located between the first polyethylene base layer and the second polyethylene base layer; the upper surface and the lower surface of the first polyethylene base layer are an upper optical surface and a lower optical surface; the transparent resin layer is composed of a plurality of parallelly-arranged first prisms and second prisms; the height of the first prisms is greater than the height of the second prisms; the first prisms and the second prisms are arranged alternately; gaps are left between respective bottom surfaces of the first prisms and the second prisms; angles between respective left slopes and right slopes of the first prisms and the second prisms are 90 degrees; and an adhesive layer is filled between the plurality of first prisms and the second polyethylene base layer as well as between the plurality of second prisms and the second polyethylene base layer. With the anti-scratch brightness enhancement film adopted, the protection of an internal micro structure can be benefitted, and light can be scattered, and chromatic dispersion of the light can be decreased, and interference can be reduced so that the Newton's ring phenomenon can be alleviated, and the uniformity of light field distribution can be improved.
Description
Technical field
The utility model relates to blooming technical field, relates in particular to a kind of anti scuffing brightness enhancement film.
Background technology
Brightness enhancement film refers to and is applied in backlight module to improve film or the thin slice of whole back light system luminescence efficiency as aim, be widely used in backlight module to be used for converging the light that light source is sent, especially conventional anti scuffing brightness enhancement film in the display devices such as display, to increase display brightness and to save display power consumption.The principle of anti scuffing brightness enhancement film be by reflection, the light outside directive observer visual angle is adjusted to observer visual angle within, so just improved the utilization factor of luminous energy that light source sends.
Summary of the invention
The utility model provides a kind of anti scuffing brightness enhancement film, and this anti scuffing brightness enhancement film is conducive to protect internal microstructure, by light scattering, in order to reduce the dispersion phenomenon of light, and reduces and interferes to alleviate Newton ring phenomenon, has improved the homogeneity of optical field distribution.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti scuffing brightness enhancement film, comprise the first tygon basic unit, the second tygon basic unit and transparent resin layer, described transparent resin layer is between the first tygon basic unit and the second tygon basic unit, described the first tygon basic unit upper and lower surface is respectively optical surface, lower optical surface, described transparent resin layer is made up of some the first prisms that are arranged in parallel and the second prism, the height of described the first prism is greater than the height of the second prism, the first prism and the second prism alternative arrangement and adjacent the first prism and the second prism leave interval separately between bottom surface, described the first prism and the second prism are left separately, angle between right tilted surface is 90 °, between some described the first prisms and the second prism and the second tygon basic unit, be filled with adhesive layer.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, the height aspect ratio of the height of described the first prism and the second prism is 1:0.6 ~ 0.4.
2. in such scheme, the height of described the first prism is 20 μ m, and the height of described the second prism is 12 ~ 10 μ m.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model anti scuffing brightness enhancement film, it can be by light scattering, in order to reduce the dispersion phenomenon of light, and reduce and interfere to alleviate Newton ring phenomenon, can reach the effect of coverage or hidden defects, improve the utilization factor of luminous energy that light source sends, and the homogeneity of anti scuffing brightness enhancement film optical field distribution; Secondly, be convenient to clean and anti scuffing, reliability and the life-span of having improved product.
