Description

Optical film with blue light suppression function

technical field

The invention relates to an optical film, in particular to an optical film with the function of suppressing blue light.

Background technique

In recent years, traditional lamps and light sources have been rapidly replaced by LED products, but also because of this, the probability of exposure to blue light in people's living environment has also increased relatively. The "blue light" mentioned above refers to a light field Strong light between 380nm and 500nm wavelength has high energy because its wavelength is shorter than that of visible light. According to current medical reports, if the human eye is exposed to blue light for a long time, it is easy to cause retinal damage, eye damage, etc. It can be seen that with the widespread use of LED products, the negative impact of blue light on the human body is bound to become an important issue that consumers must pay attention to and worry about next. question.

As far as the LED products currently on the market are concerned, if LEDs are used in the structure of lamps, the problem of blue light may be easily solved or improved through the refraction or reflection of the lampshade. However, when LEDs are used as various liquid crystals When the backlight of the display is used, because the blue light will leak out from the glass liquid crystal panel and directly enter the user's eyes, so in this case, the damage to the user's eyes caused by the blue light is no less than that of the aforementioned LED lamps. At present, most people look at liquid crystal displays for a long time no matter whether they are living or working. However, the structural design of currently visible liquid crystal display products does not consider and solve the problem of blue light, which is a major shortcoming.

Contents of the invention

The main purpose of the present invention is to provide an optical film with the function of suppressing blue light.

To achieve the above object, the present invention adopts the following technical solutions:

An optical film system with the function of suppressing blue light includes: a light-transmitting substrate, which is in the shape of a film body with a thickness, an area and light transmission, and the light-transmitting substrate includes a first surface and a second surface ; An anti-blue light primer layer, which is added on the first surface or the second surface of the light-transmitting substrate in the form of glue coating and molding, and wherein, the structure of the anti-blue light primer layer is uniformly mixed with anti-blue light particles , the anti-blue light particles have a light diffusion effect, and can produce a certain degree of inhibition effect on blue light with a wavelength between 380nm and 500nm in the light.

The main effect and advantage of the present invention is that the optical film has the function of suppressing blue light through the technical characteristics of anti-blue light microparticles mixed in the structure of the anti-blue light primer layer, which can greatly reduce the adverse effects caused by the blue light emitted by LED products And it is practical and progressive.
