Embodiment 1

[0092] A novel anti-blue light guide plate provided by the embodiment of the present invention 1 is obtained by the following method:

[0093] S1. Select the mixed material of glass and PET as the base material, and obtain a base plate integrally formed by the base material layer 1, the microprism structure layer 2, and the microstructure layer 3 through a calendering molding process. The thickness of the base plate is 3mm, and the width 1500mm, length 1800mm, the height of the prism strip is 35μm, and the top angle of the prism strip is 75°;

[0094] S2. Put the base plate on the adsorption plate 105d of the front intermittent spraying device 100 with the micro-prism structure layer facing upward, the length direction of the prism strip is consistent with the traveling direction of the base plate, and the front end of the base plate is located at the precision nozzle assembly 104b Then start the adsorption pump to fix the base plate, and then adjust the height of the precisio...

Embodiment 2

[0101] The rotation speed of the micro gear pump 106b in Example 1 was set to 15 rpm, and other parameters and conditions were kept unchanged, to prepare an anti-blue light guide plate with an anti-blue light coating thickness of 3 μm.

Embodiment 3

[0103] The rotating speed of the micro gear pump 106b in Example 1 was set to 20 rpm, and other parameters and conditions were kept unchanged, to prepare an anti-blue light guide plate with an anti-blue light coating thickness of 4 μm.

Abstract

The invention discloses a novel anti-blue-light coating, a light guide plate applying the novel anti-blue-light coating, a processing device and a processing method wherein the novel anti-blue-light coating comprises the following components: 8-25 parts by weight of cholesteric liquid crystal molecules, 1-10 parts by weight of a chiral agent, 1-5 parts by weight of a photoinitiator, 0.1-0.5 part by weight of a polymerization inhibitor, 0.05-0.10 part by weight of a conditioning agent, and 59-90 parts by weight of an organic solvent. Compared with the prior art, the anti-blue-light coating is prepared from the anti-blue-light paint provided by the invention, and the anti-blue-light coating is processed into the light guide plate, so that the defect that the existing large-size light guide plate is not anti-blue-light is overcome, and the anti-blue-light light guide plate has the following effects of small color coordinate deviation, uniform appearance color and high transparency, and the light guide plate has a good anti-blue-light effect in the wave band of 420-440nm. And the reflectivity to blue light is more than 25%. Besides, the intermittent spraying equipment solves the problem of spraying on the surface of the microprism structure layer of the existing light guide plate, and is convenient for uniformly spraying on the surface of the microprism structure layer of the light guide plate to form an anti-blue-light coating with uniform thickness.

Description

technical field [0001] The invention belongs to the technical field of light guide plates, and particularly relates to a novel anti-blue light coating, a light guide plate made of the anti-blue light coating made of the anti-blue light coating, a light guide plate processing equipment and a method for processing a light guide plate using the light guide plate processing equipment. Background technique [0002] At present, with the continuous enhancement of people's awareness of anti-blue light, the research and development and application of anti-blue light in screen protection films have gradually matured. Due to the long and other characteristics, there are relatively few studies on anti-blue light guide plates. [0003] Existing LED displays use three primary colors of red, green and blue (ie RGB) as the backlight source. 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 epit...
