Usually we buy mobile phones, especially the more expensive ones. In order to show our appreciation, we spend hundreds more without buying a steel film to protect the screen of our mobile phones.
Does the steel film really protect our screen?
1. Can the steel film protect the screen of mobile phone from bursting? It can not but play a protective role. Two days ago, I saw a TV contrast experiment. At the same height of 1.75 meters, the mobile phone without steel film and the mobile phone with steel film pasted, the screen fell to the ground, and the screen was also diluted. But it is undeniable that in many cases, only the steel film is damaged after the screen is impacted by the outside, and the screen is not.
2. Can the screen scratch? It has little effect. Nowadays, more and more mobile phones are using Corning gorilla glass, which belongs to quartz material. Its hardness is 7. Iron knives with hardness lower than this can not scratch the screen. Small stones, sand hardness is about 8, so there will be a certain threat to the screen, but our mobile phone is usually in the pocket, so the probability of contact with stone sand is still small.
3. The accidental smash of the mobile screen will produce a lot of small glass fragments with sharp edges and corners, which has a certain risk of injury to people. When toughened glass is destroyed by external forces, the fragments become small honeycomb-like fragments, but without sharp horns, they will not harm the human body.
4. At present, it is impossible to prevent fingerprint by 100% of mobile screen technology, especially in the case of sweating or oil stain on hand, but the application of toughened glass protective film can greatly improve the effect of fingerprint prevention.
Anti-scratch, anti-fall and anti-pollution are the main purposes for us to use the steel film. In fact, the mobile phone steel film has a certain protective effect on the mobile phone, making the mobile phone screen more secure. However, the quality of the steel film is very important, if you want to better protect the mobile phone, you need to buy the quality of the steel film.
