Background technology
Recent years, " blue light injury " problem increasingly cause the concern of masses." blue light " herein refers to by LED screen
The excessive blue light sent.Because LED technology is generally using blue diode as active excitation source, so sending excessive
Blue light becomes the insoluble problem of LED technology.Confirmed by medical field, excessive blue light illumination can cause human eye retina
Damage and ARM, can also the symptom such as cause insomnia.But in today's society, a large amount of mobile phones equipped with LED screen, flat board electricity
Brain, notebook computer, desktop computer and LCD TV become the essential part of people's Working Life, so can filter out
The optical thin film of excessive blue light and other harmful lights (such as ultraviolet) becomes a big focus of current thin film industry development.
At present on the market, have it is a large amount of be known as can " anti-blue light " optical thin film, but the shortcomings that generally existing is following：(1)
Filter blue light acts on very little, even wholly without there is some products also to have inhibition to visible ray；(2) most products
It is to use optical thin film made of blu-ray reflection material, the blu-ray reflection that the type product can send LED screen falls, but
More blue lights can be reflected under multiple light sources or strong sunlight and enter human eye；(3) it is to use blue-light absorbers system to have a small amount of product
Into optical thin film, but such product is more common in sunglasses, few eyeshield equipment applied to sticking film for mobile phone or electronic curtain.Have
Medical expert thinks that separating capacity of the human eye to color, therefore the practicality of anti-blue light can be influenceed by wearing such product for a long time
It is not strong.
Utility model content
To solve the problems such as prior art moderate resistance blue light optical film reflector blue light, practicality is not strong, the utility model carries
A kind of LED screen optical thin film with multiple functions is gone out.
The technical solution of the utility model is as follows：
A kind of LED screen optical thin film, the optical thin film include grease proofing pollution layer, the dura mater stacked gradually from top to bottom
Layer, anti-dazzle layer, antireflection layer, electrostatic layer, UV filters and blue absorption layer.
Preferably, grease proofing pollution layer, hard membrane layer, anti-dazzle layer, the thickness of antireflection layer are 0.04-0.06mm；Electrostatic layer
Thickness be 0.07-0.09mm；The thickness of UV filters and blue absorption layer is 0.03-0.05mm.
Preferably, UV filters are made up of the material containing ultra-violet absorber.
Preferably, blue absorption layer is made up of the material containing blue-light absorbers.
Preferably, the optical thin film also includes mucigel, and mucigel is fitted in below blue absorption layer.
Preferably, the thickness of mucigel is 0.04-0.1mm.
The beneficial effects of the utility model are：Grease proofing pollution layer of the present utility model ensure that film will not be by oil stain and fingerprint
Attachment；Hard membrane layer improves the impact resistance of film；Anti-dazzle layer reduces dazzle；Antireflection layer reduces the shadow of reflected light
Ring；Electrostatic layer reduces insulaion resistance, has reached the function of production process moderate resistance Electrostatic Absorption；UV filters served
Filter the function of ultraviolet；Blue absorption layer can absorb the excessive blue light that LED screen is sent, and reduce the injury to human eye；With
Upper each layer is cascading so that the reflectivity of the total visible light spectrum of the optical thin film is less than 0.1%, absorption of UV
More than 99%, the absorptivity of blue color spectrum is 40%~60%, has anti-blue light, filtering ultraviolet light, shock resistance, combating vertigo etc. more
Kind function.

Embodiment
Detailed explanation and illustration is carried out to structure of the present utility model with reference to Figure of description.
As shown in figure 1, LED screen of the present utility model includes the grease proofing pollution layer that stacks gradually from top to bottom with optical thin film
1st, hard membrane layer 2, anti-dazzle layer 3, antireflection layer 4, electrostatic layer 5, UV filters 6 and blue absorption layer 7.
Wherein, grease proofing pollution layer 1 is made up of nanochemistry material, and its effect is reduction of film surface tension force, make dust with
The accessible area of film reduces, and so as to ensure that film will not be adhered to by dust, oil stain and fingerprint, film is easily scraped
The oil stain and fingerprint of attachment removal, leave no trace.Hard membrane layer 2 is made up of composite, and it is increase film hardness that it, which is acted on, improves anti-
Impact capacity.Anti-dazzle layer 3 is using PET as base material, on surface after specially treated, increases roughness, realizes that multi-angle is worn
The diffusing scattering of printing opacity, reduces ambient light interference, reduces dazzle.Antireflection layer 4 is made up of three layers of reflection-reducing material, antireflective
The one or more in silica, silicon nitride, alundum (Al2O3) may be selected in 4 material of layer；Antireflection layer 4 can be by contact surface
Visible reflectance is reduced to less than 0.2%, considerably reduces the reflected light of contact surface.Electrostatic layer 5 passes through using PET as base material
Antistatic specially treated, reduces insulaion resistance, reaches the function of production process moderate resistance Electrostatic Absorption.UV filters 6 are
It is made up of the material for being mixed with the ultra-violet absorber being re-dubbed by salicylic acid esters, benzophenone class etc., serves filtering ultraviolet
Function.Blue absorption layer 7 is made up of the material for being mixed with blue-light absorbers, and material here is by polyacrylic acid lutein ester
Formed with acrylic Acid UV, wherein blue-light absorbers account for the 15-18% of material.Blue-light absorbers are organic molten by melanin powder and chemistry
Agent is formulated, and can be absorbed the excessive blue light that LED screen is sent, be reduced the injury to human eye.
It is that the whole film of protection will not adhesive dust or fingerprint that grease proofing pollution layer 1, which is placed on uppermost purpose,.Hard membrane layer 2,
Anti-dazzle layer 3, antireflection layer 4, electrostatic layer 5, UV filters 6 and blue absorption layer 7 are then according to production technology, material hardness
It is superimposed from top to bottom successively with function.Grease proofing pollution layer 1, hard membrane layer 2, anti-dazzle layer 3, antireflection layer 4, electrostatic layer 5, ultraviolet mistake
Filtering layer 6 and blue absorption layer 7 are cascading so that and the reflectivity of the total visible light spectrum of the optical thin film is less than 0.1%,
Absorption of UV is more than 99%, and the absorptivity of blue color spectrum is 40%~60%, has anti-blue light, filtering ultraviolet light, anti-impact
Hit, the multiple functions such as combating vertigo.
It is grease proofing pollution layer 1, hard membrane layer 2, anti-dazzle in order that the utility model reaches optimal using effect in the present embodiment
Dizzy layer 3, the thickness of antireflection layer 4 are 0.04-0.06mm；The thickness of electrostatic layer 5 is 0.07-0.09mm；UV filters 6
Thickness with blue absorption layer 7 is 0.03-0.05mm.More than each layer be superimposed in order successively, can by coating technique according to
Secondary coating is realized.
In the present embodiment, the optical thin film also includes mucigel 8, and mucigel 8 is fitted in below blue absorption layer.It is excellent
Selection of land, the thickness of mucigel 8 is in 0.04-0.1mm.Mucigel 8 causes the optical thin film to be easy to be pasted onto mobile phone screen, flat board electricity
