Description
Technical field
The utility model is related to a kind of bright enhancement film more particularly to a kind of bright enhancement films for improving brightness and anti-blue light.
Background technology
At present, Liquid Crystal Module is widely used in various electronic products, such as mobile phone, computer, TV, Liquid Crystal Module include
BLU (backlight module), LCD (liquid crystal display), LENS (glass cover-plate) etc., the lightening and anti-blue light function of Liquid Crystal Module into
A kind of trend of existing market.Backlight module is one of critical component of Liquid Crystal Module, and bright enhancement film is widely used in shining
Module is to be used for converging sent out light.The principle of bright enhancement film is by reflecting the light tune except directive observer visual angle
It is whole within observer visual angle, so as to improve the utilization rate that light source sends out luminous energy.In order to make bright enhancement film lightening, usually by two
Layer bright enhancement film fits together, traditional by upper and lower two layers as shown in Figure 1, the prism 200 on bright enhancement film 100 is contour structure
The method that bright enhancement film 100 is fixed together is that glue 300 is filled up between the prism of lower floor's bright enhancement film, thus is had a thick layer of
Glue 300 leads to the area for reducing 200 optically focused of prism, and glue 300 can reduce the penetrance of light, makes bright enhancement film 100
Brightness declines 13%-15%, so as to substantially reduce the brightness of Liquid Crystal Module.
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, provide and a kind of improve adding lustre to for brightness and anti-blue light
Film.
The technical solution of the utility model is as follows：A kind of bright enhancement film for improving brightness and anti-blue light, including：First adds lustre to
Film, the second bright enhancement film and the photoresist pigment with eye-protecting function.First bright enhancement film includes the first pet layer and is located at first
The first prism above pet layer, second bright enhancement film include the second pet layer and the height being located above second pet layer
Prism and low prism are equipped with several low prisms between two neighboring high prism.The first bright enhancement film bottom is equipped with one layer thin
Thin optical cement, the optical cement have the advantages that water white transparency, cementing strength are good, and especially its light transmission rate is up to 90%
More than, the high prism tip and optics glue, the low prism tip not with optics glue.
Further, the photoresist pigment silk-screen is in the first pet layer top.
Further, the photoresist pigment silk-screen is in the second pet layer bottom end.
Further, low prism there are one being set between two neighboring high prism.
Further, low prism there are two being set between two neighboring high prism.
Further, first prism, high prism and low prism are triangular structure.
Further, first prism is contour.
Using the above scheme, the utility model provides a kind of bright enhancement film for improving brightness and anti-blue light, is divided into up and down
Two membranes, the prism on the bright enhancement film of upper strata are contour structure, and the prism design on lower floor's bright enhancement film is high prism and low prism knot
Structure, high prism are staggeredly placed with low prism, and upper strata bright enhancement film bottom end is coated with a thin layer of optical cement, high prism and optics gluing
Patch, upper and lower two membranes are fixed together, and glue is not filled by between adjacent two prisms, thus glue thickness is thinned significantly, reduces
Influence to light transmission rate, improves the brightness of Liquid Crystal Module.And the light of the utility model silk-screen anti-blue light on pet layer
Pigment is hindered, can effectively stop the blue light harm from Liquid Crystal Module.
Description of the drawings
Fig. 1 is the structure diagram of traditional product.
Fig. 2 is the structure diagram of one embodiment of the utility model.
Fig. 3 is the structure diagram of another embodiment of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 2, the utility model provides a kind of bright enhancement film for improving brightness and anti-blue light, including：First adds lustre to
Film 10, the second bright enhancement film 20 and the photoresist pigment 30 with eye-protecting function.First bright enhancement film 10 includes the first pet layer 11
And be located at the first prism 12 of the top of the first pet layer 11, first prism 12 is contour, 30 silk-screen of photoresist pigment in
First pet layer, 11 top.Second bright enhancement film 20 includes the second pet layer 21 and is located at 21 top of the second pet layer
High prism 22 and low prism 23, set that there are one low prism 23, first prism 12, high prisms between two neighboring high prism 22
22 and low prism 23 are triangular structure.First bright enhancement film, 10 bottom is equipped with a thin layer of optical cement 40, the light
Learning glue 40 has the advantages that water white transparency, cementing strength are good, and especially its light transmission rate is up to more than 90%, the high prism
22 tops are pasted with optical cement 40, and low 23 top of prism is not pasted with optical cement 40.Light is from 20 bottom of the second bright enhancement film
