With tempered film, will the mobile phone screen break? Will there be traces?

Hello, the tempered film can play a good role in protecting the mobile phone screen, in some cases the mobile phone falls, because the tempered film can avoid breaking the screen, but not 100%. Due to the different angles and heights of the phone, the screen will still be broken in some cases.

The toughened film has high hardness, and there will be no scratches on contact generally, but after a long time, there will also be scratches.

As a result, there is no situation where the tempered film is fallen, for example, the mobile phone falls vertically where the corner (usually the screen is slightly larger than the tempered film) touches the ground and falls, but it is much thicker Oh The tempered film is not absolutely omnipotent, but it is better than the plastic one, and many times the mobile phone screen is broken, and it is still good.

There will also be some traces of the tempered film.

This is not necessarily, the tempered film is only a tool to protect the mobile phone screen, which can effectively improve the anti-drop and anti-pressure of the mobile phone screen, and it is not possible to completely solve the anti-drop and anti-pressure of the mobile phone screen. For example, if you fall on an object with sharp corners, the tempered film is not damaged, and the mobile phone screen is damaged. To effectively protect the mobile phone, we should also pay attention to the following aspects, add a soft silicone shell to the mobile phone, put the mobile phone in the bag, and try to put the screen inside, so as to effectively protect the mobile phone.

Tell if the phone is a broken protective film or a broken screenMethod:

1. Pick up the mobile phone and scratch the crack on the surface of the screen with your fingernails, if you feel an obvious crack, the protective film of the mobile phone will be broken;

2. The eyes look at the screen from the side, as shown below. If you can see another shadow on the screen below the phone from the crack or there is a sense of drop, the phone protective film is broken. Because there is a certain thickness between the protective film and the mobile phone, if the mobile phone film is broken, you can see the spacing on the mobile phone screen from the crack.

3. Directly tear off the protective film of the mobile phone, if the screen is broken, you also need to tear off the protective film to change the screen, if the protective film is broken, then replace the protective film and tear off the original. Therefore, directly removing the protective film is the most direct and reliable method.

4. If the screen is broken and the details are found, if the crack is found, or the degree of fragmentation is radiated outward from a point, the screen is broken, if the crack is evenly distributed, and there is no screen without defects or debris, it is a broken protective film.

You can roughly judge by touching the screen of your phone. If you can't feel the crack if you don't open the tempered film, it means that the tempered film is broken, and if you can only see the crack but can't feel it, it means that the screen is broken.

Method 1: Heads-up method.

First of all, the eyes and the screen should be basically parallel, and observe whether the crack can be seen in the light, if the crack can be seen, it means that the tempered film of the mobile phone is broken, but if you can't see it, it means that the mobile phone screen is broken.

Method 2: Tilt method.

Pick up the mobile phone, tilt the angle of about 30°, and observe whether the cracks of the mobile phone film and the cracks of the screen coincide from the side. Because if both screens are broken, the cracks on the phone will not coincide.

Method 3: Touch method.

If there is a slight crack or spread on the screen, you can gently touch the crack with your fingers, and if you can feel the crack with your fingers, it means that the tempered film is broken. However, if the fingers do not feel the crack and can only be seen through the eyes, it means that the screen is broken.

Generally, the crushing of the tempered film will not affect the display of the screen, nor will it affect the touch of the screen.

If the screen is broken, it will be divided into a broken inner screen and a broken outer screen. If the inner screen is broken, a black screen will be displayed, and no content will be displayed; The outer screen is broken, but it can't be operated on the screen, the touch fails, and the screen content will be displayed.

<> the phone tempered film will not damage the screen if it is torn off. Tempered glass protective film is the highest level of security protection of mobile phone screen, the surface hardness of the general plastic film does not exceed about 3h, the hardness of glass is about 6h, and the hardness of tempered glass reaches 9h. Mobile phone tempered film is tempered glass, belongs to safety glass, glass has quite good wear-resistant characteristics, and very hard, its Vickers hardness reached 622 to 701, tempered glass is actually a kind of prestressed glass, in order to improve the strength of glass, usually use chemical or physical methods to form compressive stress on the surface of the glass, glass to withstand external force first offset the surface stress, thereby improving the bearing capacity, enhance the glass itself wind pressure resistance, cold and heat, impact and so on.
