Problems solved by technology

[0004] A variety of high-definition anti-glare films have been proposed in the prior art. For example, a curable resin containing a variety of micron and nano particles is coated on a transparent film material and cured to cause the microparticles to coagulate and protrude from the film surface. It is easy to settle during the coating process, and it is difficult for the particles to protrude from the surface, resulting in a transparent film surface and insufficient anti-glare effect. At the same time, because more particles are added, there is also the problem of poor adhesion to the coating, resulting in poor wear resistance. , after the wear test, the particles on the membrane surface are easy to fall off and form a "powder falling" phenomenon
Another way of anti-glare film is to use the compatibility between two to three resins to form a co-continuous phase separation structure on the surface of the cured film. This structure has very good anti-glare properties, but the disadvantage is that the haze is too high , and because the resin compatibility is too poor, the adhesion of the surface resin is poor
Therefore, it is generally difficult to meet the needs of video displays, especially for the outermost protective film of the display.

Abstract

The invention relates to the technical field of thin films, and particularly relates to an anti-dazzle hardened film for liquid crystal display. The anti-dazzle hardened film comprises the following substances in parts by weight: 15-45 parts of urethane acrylate resin, 5-30 parts of an active diluent, 0.01-5 parts of a leveling agent, 3-20 parts of micron-sized organic particles, 3-10 parts of a photoinitiator, 5-35 parts of modified nano silicon dioxide, and 30-60 parts of an organic solvent. The anti-dazzle hardened film has low haze and improves light transmittance and friction resistance without losing display characteristics such as high definition and anti-dazzle performance.

Description

Technical field [0001] The present invention relates to the field of thin film technology, in particular a liquid crystal display anti-glare optical hardening film. Background technique [0002] The liquid crystal display product is developed towards high contrast, wide viewing angle, high definition and other optical demand. However, due to most of the use environments of the general image display, there is an external light source, and the light from the display surface reflects can cause glare effects, affecting the visual experience of the viewer. So the display of the display will require some processing, reducing the adverse effects of glare to watch the human eye. Therefore, the outermost protective film of the liquid crystal display requires lower haze, high light transmittance, anti-glare, and friction resistance. In particular, the trend of the liquid crystal TV today is that the size of the size is increasing and the thickness is getting thinner, the higher the require...
