What does D in tempered glass mean?

The d of the tempered film refers to the hardness, which is higher if it is strong and lower if it is weak. The so-called 8d, 9d, and 10d of the tempered film are all gimmicks made by merchants who sell mobile phone films. Normal tempered films only have right-angle edges, 2.5D and 3D, which refers to the curvature of the edge of the tempered film.

The biggest function of tempered film is to protect the glass of mobile phone screen. Since current mobile phones all use full bonding technology, replacing damaged glass requires replacing the entire screen, which is much more expensive than a mobile phone film. Plastic film is not as collision-resistant as tempered film.

The thickness of the protective layer of the tempered film is only 0.1 mm, which can completely cover the original screen surface to prevent damage and scratches from external forces, and increase the impact absorption, which is 5 times higher than the standard of PET film. The surface of this film is hard enough and scratch-resistant. Even if you scratch it hard with a knife, it will not be scratched, because the hardness of iron is lower than that of glass.

Are tempered films all smaller in size?

Yes, tempered films are all smaller. The main reason is that mobile phone screens have rounded corners. In order to keep the touch round, tempered films must be made smaller. The rounded corners of the mobile phone screen are left empty. If they are made the same size, there will be a gap around them, which may allow dust to enter. Take the iPhone 6 as an example. The iPhone 6 uses 2.5D glass, and its edges are slightly curved. Tempered films have a certain hardness. If the entire iPhone 6 screen is covered, the edges of the tempered film will warp up. Making the tempered film smaller can avoid the problem of film warping, which makes it very easy for dust to accumulate on the edges of the film.

Can I apply the tempered glass myself?

1. You can apply it yourself. Prepare tempered glass film, wiping cloth, vacuum paper, and wiping cloth.

2. Use alcohol wipes to wipe off grease and bacteria on the surface of the phone.

3. Use vacuum paper to absorb the alcohol and a small amount of dust, and then tear off the release film of the tempered glass film.

4. Hold both sides with both hands, slowly lower them vertically and tap the middle, the tempered glass film will automatically adsorb.

5. Use a wiping cloth to check the surface of the tempered glass film and the mobile phone, and the setting will be successful.
