Problems solved by technology

During daily use, the problems that are often encountered are: (1) the surface of the touch panel is easily scratched; (2) the surface of the touch panel is easily stained by fingerprints, water vapor, dust, etc.; (3) the "glare" caused by external light on the surface Dazzling"
The above-mentioned technology can only be used to suppress the adhesion of materials used in daily life such as food and cosmetics, and can easily remove these materials
The disadvantage of conventional stain-resistant anti-glare films is that fingerprints will adhere to the film after input operations with fingers, and the attached fingerprints are not easily wiped off

Abstract

A dirt resistant anti-dazzle film comprises a transparent supporter and an anti-dazzle hard coating. The component and content of the anti-dazzle hard coating are as follows when counted by weight: 15-85 parts of ultraviolet solidified resin; 1-15 parts of photoinitiator; 0.1-10 parts of organsilicon modified polyacrylate; 0.5-10 parts of anti-dazzle particles, and 15-80 parts of dissolvent. The scratchproof anti-dazzle film can effectively inhibit the adhesion of dirt of dust, oil dust and the like on the surface of the film, and furthermore the adhered dirt can be easily erased. In particular the dirt resistance is permanent, and at the same time the anti-dazzle property, scratch resistance and scratchproof quality can be maintained.

Description

technical field [0001] The present invention relates to an anti-glare film with anti-fouling properties for display devices. Background technique [0002] So far, anti-glare film is mainly used for the protection of the surface and to prevent glare in various image display devices such as LCD (liquid crystal display), touch panel, CRT (cathode ray tube), PDP (plasma display panel), EL (field effect luminescent monitors) and glare and reflections in optical discs. [0003] Touch panels are used as input means for portable information terminal devices that have been widely used in recent years. The touch panel is a device for inputting data by directly touching the surface of the display with a finger or a pen, and about 90% of the entire touch panel is a resistant film type touch panel. During daily use, the problems that are often encountered are: (1) the surface of the touch panel is easily scratched; (2) the surface of the touch panel is easily stained by fingerprints, w...
