Problems solved by technology

Although the use of ultra-fine louver technology to reduce the viewing angle can better protect personal privacy and business secrets, but the use of such a film will cause the brightness of the image to decrease, and the power applied to the backlight must be increased to compensate
In addition, the current anti-fingerprint technology that uses surface coating treatment still has unsatisfactory aspects in terms of anti-fingerprint effect and scratch resistance.

Abstract

The invention discloses a nano-sized anti-glare peep-proof fingerprint-resistant screen protecting film, which comprises an organic silica gel layer, a peep-proof polarization film, a bonding agent layer, a PET (Polyester) film layer and an anti-glare fingerprint-resistant nano coating from inside to outside. The anti-glare fingerprint-resistant nano coating takes silicon-fluorine polymers as a substrate, and is prepared by forming a layer of silicon dioxide or calcium carbonate with nano microbumps on the surface of a PET film in a in-situ polymerization manner; the peep-proof polarization film comprises a plurality of strip-shaped photoresists that are arranged in parallel, the cross section of each strip-shaped photoresist is square, and a non-transparent interlayer is arranged on the strip-shaped photoresist; and the interval of the photoresist is half of the thickness of the photoresist. The surface hardness of the nano-sized anti-glare peep-proof fingerprint-resistant screen protecting film is greater than 4H, and the fingerprint-resistant performance of the nano-sized anti-glare peep-proof fingerprint-resistant screen protecting film obviously surpasses the commercial conventional merchandises; the peep-proof polarization film adopts photoresist solidification and non-transparent matter filling technologies, and has greater innovations in material and processing method; in addition, a PC (polycarbonate) film is replaced by the PET film with the effects of tough texture, good stiffness, high transparency and low price, so that the quality is ensured, and the cost is lowered at the same time.

Description

technical field [0001] The invention relates to the field of screen sticking films, in particular to a nanometer anti-glare, anti-fingerprint, anti-peeping screen protective film. Background technique [0002] With the development of science and technology, liquid crystal display has more and more extensive application in our life, such as mobile phone, computer, automatic teller machine (ATM), TV and so on. As a high-quality product, it also requires a variety of maintenance and maintenance in order to exert its maximum effectiveness and maximize the use time. Therefore, a variety of screen film with different functions came into being. At present, the development of screen film is very rapid. In the past three years, the sales volume has increased by 10 times. The annual sales of mobile phone film alone in the domestic market reach several billion yuan. [0003] The LCD screen will absorb all kinds of dust, and dust is an important carrier of electromagnetic radiation. E...
