Abstract

The invention relates to a light-absorbing antidazzle hard coating film, and a preparation method and application thereof. The light-absorbing antidazzle hard coating film comprises an ultraviolet light curing hard coating and a transparent base material, wherein the ultraviolet light curing hard coating contains light-absorbing antidazzle particulates and is adhered on the transparent base material; the light-absorbing antidazzle particulates comprise antidazzle particles and black pigment, and is prepared by swelling the antidazzle particles by a swelling agent and wrapping the black pigment; the mass proportion of the swelling agent to the antidazzle particles is 50:1-2:1; the mass ratio of the antidazzle particles to the black pigment is 1000:1-10:1. The light-absorbing antidazzle particulates are prepared by wrapping the black pigment by the swelling agent; the antidazzle coating containing the light-absorbing antidazzle particulates is used on the transparent base material; the transparent base material has excellent antidazzle performance; a certain light-absorbing performance is also realized. The light-absorbing antidazzle hard coating film can be applied to screen surfaces and various displays such as liquid crystal displays and plasma displays; the occurrence of phenomena such as white color and glaring caused by external light and self shining can be prevented; the image quality of a display screen is improved.

Description

technical field [0001] The invention relates to a light-absorbing anti-glare hard coating film used on various displays and screen surfaces such as liquid crystal displays (LCDs) and plasma displays (PDPs) and a preparation method thereof. The light-absorptive anti-glare hard coating film can prevent external The whitening and dazzling phenomenon caused by the reflection of light and the flashing of self-illumination can improve the picture quality of the display screen. Background technique [0002] In recent years, with the rapid development of display technology, various new flat panel display (LCD, OLED, EL, PDP) products are used more and more frequently in daily life. However, in some environments, the display panel will reflect external strong light to interfere with people's eyes, causing glare, and being in this environment for a long time may easily cause visual fatigue and cause a series of inconveniences. This kind of strong light reflected from the outer surfac...
