What should I do if there are scratches on the tempered glass? How can I straighten the tempered glass if it is crooked?

Although tempered glass can protect the phone very well, its effect will be reduced by more than half if it is not properly applied. Now there are professional tempered glass applicators, but we don’t need to spend money to apply tempered glass. Applying it yourself can also achieve good results. What if the tempered glass you use has scratches? Let’s take a look at the relevant introduction of Encyclopedia Knowledge Network!

What to do if there are scratches on the tempered film

There is a simple way to remove scratches. Squeeze a proper amount of toothpaste onto a wet cloth and apply it evenly to the scratched area of ​​the screen. You will find that the scratches on the screen will disappear.

Tempered glass is a mobile phone protective film made of glass, which is 0.1 mm thin and 0.4 mm thick. This film can protect the phone from breaking the screen.

How to straighten the crooked tempered glass?

1. If there is a protective film originally, stick it with the Jingchi label and remove the original film; clean the screen surface. If there are many stains, wipe it with an alcohol bag first.

2. Then use the blue electrostatic dust removal film to clean the screen; tear off the protective film on the tempered film, align the glass film with the empty space and edge, and slowly put it down; gently press the center of the film with your fingers to make it automatically adsorbed on the screen; if there are some small bubbles, wipe them hard with a dust-free cloth to remove them.

3. Note: Make sure the screen is clean and dust-free before operating. It is best to observe it under strong light and continue the operation after confirmation.

How to choose tempered film

1. Cutting process. There are three main cutting processes for tempered glass films: straight edge, 2.5D curved edge, and 3D curved edge. The edges of straight edge tempered films are right angles and have not been polished, so they feel a bit uncomfortable. 2.5D curved edge tempered films are chamfered by a glass polishing machine, and feel smoother. 3D curved edge tempered films need to be bent by a heat bending machine, and feel basically the same as the screen, but the price will be higher.

2. Thickness. The thickness of the current tempered film is about 0.15mm-0.3mm. The thinner the tempered film is, the better the feel and light transmittance, and the better the toughness. Some high-quality tempered films can have a maximum curvature of nearly 180 degrees.

3. Anti-fingerprint. Now there are many high-quality tempered films that are anti-fingerprint. The anti-fingerprint effect currently advertised by some merchants basically refers to adding an oleophobic layer on the surface of the tempered film. But this only means that it can reduce the residual fingerprints and make it easier to wipe, but it cannot completely eliminate fingerprints.

4. Anti-blue light. The anti-blue light tempered film only dyes the glass with a layer of yellow-brown. You can achieve the same effect by lowering the brightness of the screen.

5. Anti-ultraviolet rays. The amount of ultraviolet rays emitted from the mobile phone screen is almost negligible. Although the amount of ultraviolet rays is small, other ordinary glass can also reduce it by half, but the tempered film has a better ultraviolet effect.
