A kind of blocking blue light organosilica gel and the film made thereof

Abstract

The invention provides a blue-light-blocking organic silica gel and a film made thereof. When the organic silica gel is produced, a certain amount of blue-light-filtering dye is added to the organic silica gel water to filter blue light of a certain wavelength. Silicone water is silicone pressure sensitive adhesive or silicone rubber. The beneficial effects of the present invention are: (1) simple structure and easy manufacture; (2) can effectively block high-energy short-wave blue light. By improving the optical properties of silicone, it not only retains the properties of silicone water itself, but also effectively blocks high-intensity blue light that is harmful to the eyes. The film can be used for the bonding of various modules of liquid crystal displays, and can also be used in the production of various protective films, explosion-proof films, substrate-free optical adhesives (OCA), LED displays, and LED light sources.

Description

technical field

[0001] The invention relates to a material for blocking blue light, in particular to a blue light blocking organosilica gel and a film made thereof. Background technique

[0002] Commonly used computers, TV monitors or light sources emit light when in use, and the high-energy short-wave blue light in it is very harmful to human eyes. High-energy short-wave blue light refers to light with a wavelength between 380 nanometers and 500 nanometers in visible light. High-energy short-wave blue light has extremely high energy and can penetrate the lens directly to the retina.

[0003] High-energy short-wavelength blue light irradiating the retina will generate free radicals, and these free radicals will lead to the death of retinal pigment epithelial cells. The death of epithelial cells will cause light-sensitive cells to lack nutrients and cause vision damage, and these damages are irreversible. If the irradiation time exceeds 10 seconds, this damage mechanism pla...
