Which is better, nano mobile phone film or toughened film?

There are differences in material, function, transparency, thickness and durability between the two kinds of mobile phone screen protective films.

1, material: the nano-mobile phone film is usually made of PET (polyester) with a nano-scale coating on its surface. The toughened film is made of glass, which is toughened at high temperature and has high hardness.

2. Function: The main functions of nano-mobile phone film are fingerprint prevention, oil pollution prevention, scratch prevention and screen protection to a certain extent. The main function of toughened film is to provide high impact resistance and scratch resistance, and to protect the screen of mobile phone from hard objects.

3. Transparency: Nano-mobile phone films are usually highly transparent and will not have much impact on the screen display. The transparency of toughened film is also higher, but it may be slightly lower than that of nano-mobile phone film.

4. Thickness: relatively thin, usually around 0. 1mm ... The thickness of the tempered film is usually between 3mm and 6mm, which is thicker than that of the nano mobile phone, but it is still thin enough to not affect the portability of the mobile phone too much.

5. Durability: Nano-mobile phone membrane is relatively low in durability and easy to wear, and may need to be replaced regularly. Tempered film has high durability and can provide longer screen protection.
