preparation example Construction

[0054] The present invention also provides a method for preparing the anti-blue light guide plate described in the above technical solution, comprising: coating the anti-blue light coating liquid on one side surface of the main body of the light guide plate, and curing after UV irradiation to form an anti-blue light functional layer.

[0055] Wherein, the raw material components of the anti-blue light coating solution are consistent with those described in the previous technical solution, and will not be repeated here.

[0056] In the present invention, the coating method is not particularly limited, and it can be a conventional coating method known to those skilled in the art, such as rod coating method, dimple coating method, knife coating method or spray coating method.

[0057] After the above coating, UV light curing is carried out. In the present invention, the conditions of the UV light are: the UV lamp used is a 320-480mm long high-pressure mercury lamp, and the lengt...

Embodiment 1

[0066] 1. Raw materials for anti-blue light layer coating liquid:

[0067]

[0068] Stir and mix the above components in proportion at room temperature to obtain an anti-blue light coating solution.

[0069] 2. Preparation of light guide plate:

Abstract

The invention provides an anti-blue-light light guide plate, a preparation method thereof, a backlight module and a liquid crystal display panel. The anti-blue-light light guide plate provided by the invention comprises: a light guide plate body; and an anti-blue-light functional layer which is compounded on the surface of one side of the light guide plate body, wherein the anti-blue-light functional layer is formed by curing raw materials comprising the following components: 93.8-95.3 wt% of a UV type resin film forming material; 3.7-4.8 wt% of a photoinitiator; 0.5-1.0 wt% of a blue light absorbent; and 0.45-0.55 wt% of an auxiliary agent. A certain UV type resin film forming matter, a photoinitiator, a blue light absorbent and an auxiliary agent are matched according to a certain proportion to form a coating liquid, and the coating liquid is coated on a light guide plate body and cured to form a blue light preventing functional layer. By adopting the specific coating liquid, not only can blue light be effectively absorbed to achieve an eye protection function, but also the brightness and chromaticity of the material can be ensured.

Description

technical field [0001] The invention relates to the field of optical materials, in particular to an anti-blue light guide plate and a preparation method thereof, as well as a backlight module and a liquid crystal display panel. Background technique [0002] As we all know, blue light is the part of visible light closest to ultraviolet rays, with a wavelength range of 380-500nm and strong energy. Due to its short wavelength, it will penetrate the lens of the human eye and reach the retina. Blue light can easily cause human eye fatigue and macular degeneration, which is an irreversible process that can lead to vision loss or even blindness. Blue light is also a regulator of the body's biological clock, which not only affects people's sleep, but also increases the incidence of major diseases. [0003] Under natural conditions, macular lesions occur very slowly. With the superiority of human life style, our eyes have been exposed to digital products such as computer monitors,...
