Tempered glass screen protector 2.5D and 3D

Tempered glass belongs to safety glass. Glass has excellent resistance and hard.Toughened glass is a kind of prestressing force glass actually, to increase the intensity of glass, use chemical or physical method normally, form compressive stress on glass surface, when glass bears external force, cancel surface stress, raised bearing capacity thereby, strengthen glass pression resistance.

Tempered glass screen protector is the highest level of security protection for the mobile phone screen.The surface hardness of general plastic film does not exceed 3H, the hardness of glass is about 6H, and the tempered glass hardness reached 9H.

The toughened film is protective for mobile phones, but it has to be said that the protection of the toughened film is also limited, beyond the limit,the function of the toughened film is Anti-explosion.

First introduce the structure of the tempered glass screen protector.At the beginning, it is hydrophobic and oleophobic coating, then it's a layer of tempered glass. AGC, Corning and Nanbo glass are usually used. Different companies have different material quality. That's why the tempered glass screen protector price is so different.

And then there's a layer of glue, Toyo AB glue, which Anti explosion when it was broken seriously , so the screen doesn't fly everywhere.

And now the general idea of how many "D", there is just a gimmick. Generally only 2.5D and 3D, as for 6D, 9D just business gimmick.2.5D refers to the film around the polished treatment,the 3D is curved and can fit the arc edge.Let me draw a picture to help you understand.

(As for the 6D and 9D,merely gimmicks, there is no practical significance)

Half screen refers to the film only covers the flat area of the phone screen, the arc edge is not covered!! The reason is that the cost is lower.Curved screen means that the film is curved and basically covers the arc edge.

Transparency more than 90 percent is very high, someone say that more than 99 percent are actually brag, does not exist absolutely.
