Photodiffusion film with blue light shielding function

Abstract

The invention relates to a photodiffusion film with a blue light shielding function. The photodiffusion film is composed of a base material layer, a photodiffusion layer and a blue light shielding layer, wherein the two surfaces of the base material layer are provided with the photodiffusion layer and the blue light shielding layer respectively. According to the photodiffusion layer, organic silicon resin spherical micro-powder is evenly dispersed in base materials, the thickness of the organic silicon resin spherical micro-powder is 5% - 20% of the thickness of the whole film, and the weight of the organic silicon resin spherical micro-powder is 0.5% - 2% of the total weight of the photodiffusion layer. According to the blue light shielding layer, blue light shielding particles are evenly dispersed in the base materials, the thickness of the blue light shielding particles is 5% - 20% of the thickness of the whole film, and the weight of the blue light shielding particles is 0.5% - 2% of the total weight of the blue light shielding layer. The photodiffusion film has the advantages of being high in haze, moderate in light transmittance, and good in stability of haze and light transmittance and has a blue light shielding function. Solutions are not used during photodiffusion film manufacturing, and therefore environmental friendliness is realized. Meanwhile, manufacturing technology is simple, price is low, application prospects are good, and market value is high.

Description

technical field [0001] The invention relates to a light diffusion film, in particular to a light diffusion film with blue light shielding function. Background technique [0002] Diffusion film is a film that can convert point and line light sources into line and surface light sources with light diffusion function. When the light passes through the diffusion layer, the light will undergo many refraction, reflection and scattering phenomena, thus causing the effect of optical diffusion, which belongs to the optical film. Diffusion films are widely used in flat panel displays, LED lights and other fields. [0003] The traditional diffusion film is mainly biased towards light diffusion, that is, light diffusion particles are added to the matrix, without consideration of improving its blue light shielding performance. With the development of the LED industry, the application of LEDs in daily life is becoming more and more extensive. The reason why the white light emitted by th...

In addition, there is another point, the longer the LED lamp is lit, the faster the phosphor in the light source decays, and as a result, the blue light band that the human eye is exposed to becomes more and more intense, thus causing damage to the human eye

Therefore, working under LED lights containing blue light for a long time can easily cause dizziness and discomfort, and even cause eye damage, which will increase the chance of eye diseases
