What is the transparent film under the outer screen of mobile phone?

The invisible film of mobile phone is a liquid coating of titanium dioxide nanotechnology. As long as it is evenly applied to the screen and back of the mobile phone, after waiting for 10 minutes, your mobile phone will wear a strong protective vest with a hardness of 9H, which can effectively prevent fingerprints and hydrophobicity, even if it is smashed with a knife or even a hammer.

The working principle of this mobile phone liquid film is actually very simple. Generally, the microstructure of ordinary glass surface is actually grooved, while the mobile phone liquid film adopts the patented nano-liquid film technology, which can fill the grooves on the glass surface after being coated on the mobile phone screen to form a powerful invisible film. Not only wear-resistant, waterproof, anti-fouling, but also sterilization, vision protection, and instant improvement of touch.
