Generally, the surface hardness of plastic film is less than 3 hours, the hardness of glass is about 6 hours, and the hardness of tempered glass reaches 9 hours. However, this does not mean that the tempered glass film can prevent the broken screen of the mobile phone.

In terms of anti-fall, in fact, whether the mobile phone is bad or not really depends on luck. Tempered glass film claims to be anti-fall, which can only reduce the probability of broken screen of mobile phone.

However, tempered glass film is not useless, but a high-end new product with the strongest screen protection at present. When our mobile phone falls, the toughened film is like the second outer screen of the mobile phone, which can really absorb some injuries and reduce the probability of broken screen.

Why can the toughened film prevent the screen from being broken?

Tempered glass film consists of glass film and electrostatic film. When subjected to pressure or impact, the glass film first bears tension and sacrifices itself. Fragments of the glass film will stick to the electrostatic film and will not hurt people.

So nothing is absolute, but it has a relative protective effect on mobile phones.
