There are many types of touch screen protective films on the market, including high permeability film, frosted film, diamond film, tempered film, etc.,touch screen computer， and the price ranges from a few yuan to a hundred yuan. Deeply study the material of the protective film, there are different types of PVC, PET, AR, PE and so on. With such a big difference, the scratch resistance of the protective film will of course be different.
1PET material protective film
This is the most common type of protective sticker on the market. The PET protective film has higher hardness and higher scratch resistance. The PET protective film relies on electrostatic adsorption, which is easier to foam and fall off, but even if it falls off, it can be reused after washing it in clean water.
2 Tempered glass protective film
Tempered glass film is a new type of screen protection material. According to reports, this type of protective film has high-strength protection capabilities and a thickness of only 0.4 mm. The light transmittance is as high as 98%, and its main functions are explosion-proof, anti-blue light, and anti-myopia. It prevents the screen from being damaged by external forces and increases the impact absorption, which is 5 times higher than the standard of PET film.
Regarding the choice of protective film, in addition to the material, it is often seen from the light transmittance and wear resistance. However, most of the low-quality films on the market generally have a light transmittance below 80%, which seriously affects the display effect of the screen. When it comes to wear resistance H, the higher the intensity of the hardening treatment, the more likely the rainbow pattern to appear on the screen, and the greater the impact on human vision. influential. There is a phenomenon that everyone feels the same. When we tear off the protective film, we often feel that the screen is clearer and brighter.
