Abstract

The invention discloses an anti-blue-light coating, a coating, a light guide plate using the anti-blue-light coating, a preparation device and a preparation method, and the anti-blue-light coating comprises the following components in percentage by mass: 0.1%-20% of nanocrystalline, 0.1%-8% of a photoinitiator, 10%-90% of UV curing resin, 1%-25% of a reactive diluent, 0.1%-5% of other additives and 1%-60% of a solvent. Compared with the prior art, the anti-blue-light coating is formed by adopting the anti-blue-light coating provided by the invention, and the light guide plate is prepared by matching the anti-blue-light coating with other material layers, so that the anti-blue-light light guide plate has the following effects of small color coordinate deviation, uniform appearance color, high transparency and good adhesive force, and the anti-blue-light light guide plate has good anti-blue-light effect in the wave band of 420-440nm. And more than 25% of blue light can be absorbed. Besides, by the adoption of the slit intermittent coating device, the problem of coating of an existing light guide plate microprism face is solved, and the surface of a microprism structure layer of the light guide plate can be evenly coated conveniently to form an anti-blue-light coating with the even thickness.

Description

technical field [0001] The invention belongs to the technical field of light guide plates, and in particular relates to an anti-blue light coating, an anti-blue light coating, a light guide plate applying the anti-blue light coating, a light guide plate preparation device and a method for preparing a light guide plate by using the light guide plate preparation device. Background technique [0002] At present, the three primary colors of red, green and blue (ie RGB) are used as the backlight source in the LED display. Studies have shown that the blue light (420-460nm) in the backlight source can penetrate the lens and reach the retina, causing the retinal pigment epithelial cells to die, and then damage. Vision; especially in the 420-440nm band, the damage to the eyes is more serious. Therefore, it is very important to effectively block the blue light in the 420-440nm band to protect the eyes. [0003] At present, in order to prevent blue light from harming the eyes, the comm...
