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 for flat-panel monitor screen or illuminating obstruct blue light diffusion barrier.
Background technology
The effect of optical diffusion is the area source that the light of pointolite or line source is evenly diffused into homogeneous, high brightness.This optical diffusion is widely used in the backlight module and novel illumination light source of flat-panel monitor, as TV, computer monitor, notebook computer, mobile phone, digital camera, MP4 player, GPS navigation instrument and various daily and industrial lighting source etc.
And high energy shortwave blue light is very large to people's eye injury in the light that these displays or light source send in use.Shortwave blue light refer to visible ray medium wavelength in 380 nanometers to the light between 500 nanometers.
Shortwave blue light has very high energies, can penetrate the through retina of crystalline lens.Blue light illumination retina can produce free radical, and these free radicals can cause retinal pigment epithelium decline, thereby epithelial decline can cause photaesthesia cell to lack nutrient causes vision impairment, and these damages are irreversible.If irradiation time exceedes 10 seconds, this its Main Function of infringement mechanism, and be more than the several times of pyrolytic damage.
Blue light causes producing the main cause of digital visual fatigue (DEF) just.Luminous ray focuses on back focus difference within the eye, can form focal length poor between bifocal.This is the main cause that forms blurred vision.Long-time visual fatigue can cause other fatigue symptoms.Injecting of blue light can the poor and dimness of vision degree of aggravation focal length.Be that focus does not drop on retina, but dropped between retina and crystalline lens because blue light is after focusing on, increased the focal length that light focuses within the eye poor.
Conventionally; ordinary optical diffusion barrier is only to complete the diffusion to light, and for the blue light producing in electronic curtain or light source luminescent process, without any safeguard measure; human eye is exposed in high-octane shortwave blue light, people's eye health is formed to very big hidden danger.
So need a kind of product, there is the effect that intercepts blue light, do not affect again the basic function of diffusion barrier.
Summary of the invention
The present invention, for overcoming the defect of existing product, has the effect that suppresses blue light, good optics diffusion.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Intercept blue light diffusion barrier, it comprises base material and is bonded to the anti-blue light diffusion layer of base material one or two sides, contains anti-blue light optics diffusant, resin in anti-blue light diffusion layer.
Described base material is the one in mylar, polycarbonate film, nylon film, polyethylene film, polyvinyl chloride film, and base material thickness is 18-200 micron.
Described anti-blue light diffusion layer is to be that the coating fluid of 1:0.2-6 anti-blue light optics diffusant, resin or light-cured resin anchors on the surface of described base material and forms by containing mass ratio, and the thickness of anti-blue light diffusion layer is 10-50 micron.
Described anti-blue light optics diffusant is the resin microballon that contains metal complex class dyestuff, can be the one in polyacrylate, the polymethylmethacrylate that contains metal complex class dyestuff that contains metal complex class dyestuff, the polystyrene that contains metal complex class dyestuff or the polysiloxane that contains metal complex class dyestuff, mean grain size be 1-40 micron.
Described resin is selected from acryl resin, vibrin, urethane resin, epoxy acrylate, light-cured resin is the acrylic resin of ultraviolet light polymerization, also comprising can be by the urethane acrylate of ultraviolet light polymerization, polyester acrylate, polyether acrylate, pure acrylate or organic siliconresin.
Described anti-blue light optics diffusant is inhibited to the light of wavelength 380-500 nanometer; Make to intercept blue light diffusion barrier blue light is had to iris action, guarantee that the optics diffusion of diffusion barrier reaches request for utilization simultaneously.
The present invention can, by regulating the thickness of anti-blue light diffusion layer and institute to add the concentration of anti-blue light optics diffusant, change the rejection rate of obstruct blue light diffusion barrier to blue light, and variation range is 10～70%.
Advantage of the present invention:
The present invention adds the thickness of particle diameter, density and the coating of anti-blue light optics diffusant in anti-blue light diffusion layer by being controlled at, make this obstruct blue light diffusion barrier have the inhibiting effect to blue light; The present invention is inhibited to the light of wavelength 380～500 nanometers, has greatly reduced the injury of the eyes of blue light to people.
