Blue light-filtering optical film and manufacturing method thereof

Abstract

A liquid resin solid component mixed with phenylene ester is coated at least one face of a transparent substrate; after the liquid resin solid component is hardened and set under ultraviolet irradiation, a diffusion film with a blue light filtering effect can be integrally combined on the surface of the transparent substrate; and a shielding role of preventing the transparent substrate from being physically damaged can be played, the phenylene ester in the diffusion film can generate blue light filtering effects on a passing light source, and under effects of the diffusion film, glaring can be effectively lessened to enable the passing light source to be uniform.

Description

technical field [0001] The present invention relates to an optical film, in particular to an optical film for filtering blue light that can effectively reduce glare and has better structural strength, and a manufacturing method for the optical film for filtering blue light related thereto. Background technique [0002] Press, modern people are under the impact of the communication age, and almost everyone cannot do without 3C products such as TV, computer, notebook or tablet computer and touch mobile phone; for the sake of clarity, most of the existing 3C products strongly require Resolution and brightness, behind these products, our common white LED is generally composed of blue light emitted by the semiconductor chip, and a yellow light phosphor arranged in front of the chip absorbs the blue light and emits yellow light. The increase in light intensity means increasing the intensity of blue light from the source. [0003] On the other hand, due to the better luminous effi...

Problems solved by technology

[0006] Similar to the existing blue light filter optical film, the scattering particles in the material produce an anti-glare effect by scattering the light. Not only does the anti-glare effect produced by it be limited, but too many layers of glued materials will also make the overall optical film The light transmittance decreases, but the brightness of the screen must be increased to produce the expected visual effect, which will invisibly cause more damage to the eyes, and the products it uses are relatively power-hungry.
