How often should the tempered film be replaced?

The impact and lifespan of long-term use of tempered film:

1. It is a reasonable time to replace the tempered glass screen protector once every six months, because the oleophobic layer will be worn away and the screen protector will start to turn yellow.

2. The longer the tempered film is applied, the yellower it will become. When the tempered film turns yellow, it will affect the light transmittance, which may make it difficult to see the screen content outdoors. In addition, when it turns yellow, it will affect the color performance of the screen and make the screen display color cast.

3. Currently, most tempered films are coated with an oleophobic layer to improve the feel, but the oleophobic layer is a coating after all, and it will fall off after touching for a long time. After the coating is worn off, the feel will be like the glass of your window, which is dry and easily stained with fingerprints, and cannot be wiped off no matter how hard you wipe it. Especially now is summer, the mobile phone screen is more easily stained with fingerprints, affecting the clarity of the screen.

Mobile phone film, also known as mobile phone beauty film or mobile phone protective film, is a kind of cold-mounted film that can be used to mount the surface of mobile phone body, screen and other tangible objects. There are many types of mobile phone film, which can be divided into: mobile phone screen protective film, mobile phone body protective film according to its use; the function ranges from the original simple anti-scratch protective film to the functional protective film series launched by idskin and chinee, which can be divided into: anti-peep film, mirror film, AR film, frosted film, high-definition film, anti-scratch protective film, 3D film, mobile phone body anti-scratch protective film, diamond film, tempered film, etc.

How to judge the quality of tempered film

Scratch resistance: A good tempered glass film can withstand scratches from hard and sharp objects such as blades, scissors, and keys.

Smoothness of touch: A good tempered glass protective film feels very delicate and smooth to the touch, and feels better than the original touch screen of many mobile phones. A poor glass film is rough and not smooth enough, and it feels sticky when sliding on the phone.

Size fit: Good tempered glass films have relatively high cutting requirements, with perfect coverage of all sizes, especially in some holes, and no bubbles when applied.

Explosion-proof performance: A good tempered glass protective film has good toughness, density, and strength. This is mainly reflected in the fact that when the glass is broken, it maintains an overall mesh pattern, and the glass fragments will not scatter and easily hurt people! As long as you are brave enough, you can completely test it by bending the glass film. The most intuitive way to tell whether the glass film is good or not is to see whether the glass fragments fly.

Light transmittance: Light transmittance is the only way to test all protective films. The simplest and most direct way is to see with your eyes and feel with your vision! Good tempered glass films have high density and high light transmittance, so the image quality you see is relatively high-definition. Poor tempered glass films have low density, so the image quality does not look so clear.

The difference between UV film and tempered film

UV film is also called hydrogel film. It can be adapted to curved screen mobile phones and can cover the entire screen of the phone. The effect is very good and will not hinder the front display of the screen. However, UV film cannot play an anti-collision role.

Tempered film needs to be adapted to the screen of the mobile phone and can withstand the impact of the front of the mobile phone screen, but the impact of the side of the mobile phone is very likely to cause the tempered film to break. One of the biggest advantages of using tempered film is that there will be no bubble problem between the mobile phone screen and the protective film, and it will not affect the use of mobile phone cases and other mobile phone accessories.

Common problems with mobile phone protective films: 1. Affecting fingerprint recognition - We know that tempered films have a certain thickness, and with daily use, tempered films will also be worn, which can affect the success rate of screen fingerprint recognition. The best way to solve this problem is to use the official protective film, which is specially designed for your own mobile phone screen and can greatly reduce the fingerprint recognition problem.

2. Affecting facial recognition - Due to the problem of the tempered film material, the success rate of mobile phone facial recognition may be reduced. At this time, we can choose some tempered films of better quality or remove the mobile phone screen protector. The hardness of the mobile phone screen can fully cope with general impact, so there is no need to apply a protective film.
