Abstract
The invention discloses a kind of anti-blue light optical diffusion, it includes base material and anchors at the anti-blue light diffusion layer that base material single face or two surfaces are formed and constitute, anti-blue light diffusion layer be by resin microbeads, resin containing metal complex class dyestuff coating solution set on substrate surface；The present invention is by controlling thickness and the concentration of added metal complex class dyestuff of anti-blue light diffusion layer, change the anti-blue light optical diffusion rejection rate to blue light, this anti-blue light diffusion barrier is made to have the inhibitory action to blue light, the present invention is inhibited to the light of wavelength 380 500 nanometer, greatly reduces the blue light injury to the eyes of people.
Description
Technical field
The present invention relates to a kind of for flat panel display screen or illuminating anti-blue light optical diffusion.
Background technology
The effect of optical diffusion is that the light of spot light or line source uniformly diffuses into homogeneous, the face light of high brightness
Source.This optical diffusion is widely used in backlight module and the novel illumination light source of flat-panel monitor, as
TV, computer monitor, notebook computer, mobile phone, digital camera, MP4 player, GPS navigator
And various daily and industrial lighting source etc..
And high energy shortwave blue light is non-to the eye injury of people in the light that these displays or light source send in use
Chang great.Shortwave blue light refers to visible ray medium wavelength light between 380 nanometers to 500 nanometers.
Shortwave blue light has very high energies, it is possible to penetrates crystalline lens and goes directly retina.Blue light illumination retina can produce
Raw free radical, and these free radicals can cause retinal pigment epithelium to become feeble and die, the decline of epithelial cell can be led
Cause photaesthesia cell lacks nutrient thus causes vision impairment, and these damages are irreversible.If irradiated
Time more than 10 seconds, its Main Function of this damaging mechanisms, and be pyrolytic damage several times more than.
Blue light results in the main cause of digital visual fatigue (DEF) just.Luminous ray focuses within the eye
Back focus is different, can form focal length poor between bifocal.This is the main cause forming blurred vision.Long
Time visual fatigue can cause other fatigue symptoms.Injecting of blue light can aggravate focal length difference and the dimness of vision
Degree.Being because blue light after over-focusing, focus does not falls within retina, but falls at retina with crystalline
Between body, increase the focal length that light focuses within the eye poor.
Generally, ordinary optical diffusion barrier is only to complete the diffusion to light, and for electronic curtain
Or the blue light produced during light source luminescent, there is no any safeguard measure, human eye is exposed to high-octane shortwave
In blue light, the eye health of people is constituted very big hidden danger.
So needing a kind of product, there is the effect intercepting blue light, the most do not affect the basic function of diffusion barrier.
Summary of the invention
The present invention, for overcoming the defect of existing product, has the effect of suppression blue light, excellent optics diffusivity
Energy.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
Anti-blue light optical diffusion, it includes base material and is bonded to the anti-blue light diffusion of base material one or two sides
Layer, containing optical diffusant, anti-blue light resin in described anti-blue light diffusion layer.
Described base material is that polyester film, polycarbonate film, nylon film, polyethylene film, polyvinyl chloride are thin
One in film, base material thickness is 18-200 micron.
Described anti-blue light diffusion layer is by being 1:0.2-6 resin microbeads, the painting of anti-blue light resin containing mass ratio
Cloth liquid anchors at formation on the surface of described base material, and the thickness of anti-blue light diffusion layer is 10-50 micron.
Described anti-blue light resin is selected from the acrylic resin containing metal complex class dyestuff, containing metal complex class dye
The polyester resin of material, the polyurethane resin containing metal complex class dyestuff, containing the epoxy of metal complex class dyestuff
Acrylate, containing the ultraviolet curing acrylic resinoid of metal complex class dyestuff, including passing through ultraviolet
The urethane acrylate containing metal complex class dyestuff of photocuring, containing the polyester third of metal complex class dyestuff
Olefin(e) acid ester, containing the polyether acrylate of metal complex class dyestuff, containing the pure acrylic acid of metal complex class dyestuff
Ester, containing the organic siliconresin of metal complex class dyestuff.
Described optical diffusant is resin microbeads, can be polyacrylate, polymethyl methacrylate, polyphenyl
One in ethene or polysiloxanes, average grain diameter is 1-40 micron.
Described anti-blue light optical diffusant is inhibited to the light of wavelength 380-500 nanometer；Make to prevent
Blue light optical diffusion barrier has iris action to blue light, ensures that the optics diffusion of diffusion barrier reaches to use simultaneously
Requirement.
The present invention can be by regulating the thickness of anti-blue light diffusion layer and the dense of added metal complex class dyestuff
Degree, changes the anti-blue light optical diffusion rejection rate to blue light, and excursion is 10～70%.
Advantages of the present invention:
The present invention, by controlling concentration and the thickness of coating of the metal complex class dyestuff of interpolation in resin, makes
Obtain this anti-blue light diffusion barrier and there is the inhibitory action to blue light；The present invention light to wavelength 380～500 nanometer
Inhibited, greatly reduce the blue light injury to the eyes of people.
