The glass has quite good wear resistance and is very hard, and the Vickers hardness of the glass reaches 622 to 701. The tempered glass is actually prestressed glass, and in order to improve the strength of the glass, a chemical or physical method is usually used to form compressive stress on the surface of the glass, and the glass firstly counteracts surface stress when bearing external force, so that the bearing capacity is improved, and the wind pressure resistance, the cold and hot property, the impact property and the like of the glass are enhanced. And the toughened glass protective film is used for protecting the mobile phone screen at a higher security level.

But traditional cell-phone tempering membrane does not do corresponding processing at the camera opening part, and then will appear opening part edge butt joint dirt, and the later stage can directly influence the sealed effect of opening part, and then will take the opening edge when handling, and then the intramembranous bubble appears.
