Abstract
The invention discloses a blue light-blocking diffusion film. The blue light-blocking diffusion film comprises a substrate and a blue light-proof diffusion layer fixed on a single surface or two surfaces of the substrate; and the blue light-proof diffusion layer is formed by coating and fixing a coating liquid with metal complex dye-containing resin beads and resin on the surface of the substrate. Through controlling the particle size of the metal complex dye-containing resin bead added in the diffusion film, the density and the thickness of the coating layer, a certain blue light inhibition effect by the blue light-blocking diffusion film is provided, the blue light-blocking diffusion film can play an inhibition role on light with wavelength of 380 to 500nm, and harm to eyes of a person by the blue light can be greatly reduced.
Description
Technical field
The present invention relates to a kind of be used for flat panel display screen or illuminating obstruct blue light diffusion barrier.
Background technology
The effect of optical diffusion is that the light of point source or line source is uniformly diffused into into homogeneous, high brightness area source.
This optical diffusion is widely used in the backlight module of flat faced display and novel illumination light source, and such as TV, computer show
Show device, notebook computer, mobile phone, digital camera, MP4 players, GPS navigator and various daily and industrial lighting source
Deng.
And high energy shortwave blue light is very big to the eye injury of people in the light that these display or light source send when in use.
Shortwave blue light refers to light of the visible ray medium wavelength between 380 nanometers to 500 nanometers.
Shortwave blue light has very high energies, can penetrate the through retina of crystalline lenses.Blue light illumination retina can be produced from
By base, and these free radicals can cause retinal pigment epithelium to become feeble and die, and the decline of epithelial cell can cause photaesthesia cell
Lack nutrient so as to cause vision impairment, and these damages are irreversible.If irradiation time was more than 10 seconds, this infringement
As many as mechanism its Main Function, and be the several times of pyrolytic damage.
Blue light exactly causes to produce digital visual fatigue（DEF）Main cause.Luminous ray focus within the eye after focus
Difference, can form focal length poor between bifocal.This is the main cause to form blurred vision.Long-time visual fatigue can draw
Send out other fatigue symptoms.Injecting for blue light can aggravate focal length difference and dimness of vision degree.Blue light is because after focusing, it is burnt
Point is not fallen within retina, but fall between retina and crystalline lenses, increase focus that light focuses within the eye away from
Deviation.
Generally, ordinary optical diffusion barrier is can only to complete the diffusion to light, and for electronic curtain or light
The blue light produced in the luminescence process of source, without any protective measure, human eye is exposed in the shortwave blue light of high-energy, to people's
Eye health constitutes very big hidden danger.
So a kind of product is needed, the effect with obstruct blue light, and do not affect the basic function of diffusion barrier.
The content of the invention
The present invention is used to overcome the defect of existing product, with the effect for suppressing blue light, excellent optics diffusion.
To solve above-mentioned technical problem, the technical solution used in the present invention is：
Blue light diffusion barrier is intercepted, it includes base material and is bonded to the anti-blue light diffusion layer of base material one or two sides, anti-
Contain anti-blue light optical diffusant, resin in blue light diffusion layer.
The base material is in mylar, polycarbonate film, nylon film, polyethylene film, polyvinyl chloride film
One kind, base material thickness is 18-200 microns.
The anti-blue light diffusion layer be by containing mass ratio be 1：0.2-6 anti-blue light optical diffusants, resin or photocuring
The coating fluid of resin anchors at what is formed on the surface of the base material, and the thickness of anti-blue light diffusion layer is 10-50 microns.
The anti-blue light optical diffusant is the resin microbeads containing metal complex class dyestuff, can be containing metal complex
The polyacrylate of class dyestuff, the polymethyl methacrylate containing metal complex class dyestuff, containing metal complex class dyestuff
One kind in polystyrene or the polysiloxanes containing metal complex class dyestuff, mean diameter is 1-40 microns.
The resin is selected from acrylic resin, polyester resin, polyurethane resin, epoxy acrylate, and light-cured resin is
The acrylic resin of ultraviolet light polymerization, also including can be by the urethane acrylate of ultraviolet light polymerization, polyester acrylic
Ester, polyether acrylate, pure acrylate or organic siliconresin.
Described anti-blue light optical diffusant is inhibited to the light of wavelength 380-500 nanometers；So that intercepting blue
Optical diffusion film has iris action to blue light, while the optics diffusion for ensureing diffusion barrier reaches use requirement.
The present invention can pass through to adjust the thickness of anti-blue light diffusion layer and the concentration of added anti-blue light optical diffusant,
Change the rejection rate for intercepting blue light diffusion barrier to blue light, excursion is 10～70%.
Advantages of the present invention：
The present invention adds particle diameter, density and the coating of anti-blue light optical diffusant by control in anti-blue light diffusion layer
Thickness so that this obstruct blue light diffusion barrier has inhibitory action to blue light；The present invention is to 380～500 nanometers of wavelength
Light is inhibited, greatly reduces injury of the blue light to the eyes of people.
