Many people don’t know that the tempered film is actually not anti-fall because the strength of the mobile phone screen itself is much stronger than that of the tempered film.
However, I still recommend sticking! Because the tempered film has an oleophobic layer, it can not only prevent sweat but fingerprints
It can also make the screen smoother and feel more secure after the film is applied, right?
So, how to choose tempered film?
1. Full coverage or incomplete coverage
In fact, it is also called full screen or half screen. Since the edges of many mobile phones are slightly curved screens, there is no way to fit them all together, so the first half-screen tempered film appeared on the market. If you feel that it affects the appearance, you can choose a full-screen black edge tempered film.
2, 2D, 2.5D and 3D
The full-coverage tempered film is to wrap your phone screen as much as possible. But now more and more mobile phones have curved screens. To achieve “full coverage”, our tempered film also needs to have a certain curvature. So, 2D, 2.5D, 3D membranes appeared. 2.5D tempered film is polished on the glass, and 2D is a square glass. Because our mobile phone is curved, so in terms of coverage: 3D > 2.5D > 2D.
3. Hardness
Hardness – The nominal hardness of the mobile phone film is H (hardness) pencil hardness, the highest parameter is 9H, which is roughly equivalent to the Mohs hardness between 6 and 7, so the hardness of the tempered film is very reasonable and normal at “9H” of. .
4. Thickness
The thinner the natural thickness, the better the experience. The best tempered film thickness can be between 0.2mm-0.3mm. 0.3mm is the mainstream thickness on the market at present. A dozen or so pieces are basically this thickness or even thicker. As for the transparent feel, there is no need for any requirements. 0.2mm is the mainstream thickness of the current mid-end film, the permeability and feel are excellent, and the price is slightly expensive.
