How to choose a mobile phone screen protector?  These parameters are the key

Mobile phone screen protector have become a necessity. Sometimes the screen protectors arrive first before the new phone arrives. After all, the current mobile phone screens are really not cheap. It is very distressing to replace the screen once broken, and the mobile phone screen protector can be very good. To avoid the phone screen from being shattered, it is relatively cost-effective to replace the phone screen protector.

 

 

However, many people are often confused when choosing a film, because there are too many mobile phone screen protectors on the market, and they don't know how to judge which mobile tempered glass is suitable. Today, WEADDU will give you a serious popularization of what parameters should be paid attention to when choosing a mobile phone screen protector, and what kind of parameters are good.

 

After understanding, you can choose the best tempered glass screen protector by yourself according to the parameter knowledge, no more worries. Please continue reading below for details.

 

 

 

 

In the era of curved screens, the coverage of mobile phone screen protectors is a concern for many people, because only with full coverage can the screen of mobile phones be better protected. The mobile screen protector parameter related to coverage is the curvature, the so-called curvature, which is the radian of the edge of the screen protector. At present, there are only three different curvatures on the market: 2D, 2.5D, and 3D. 2D is a flat surface, 2.5D is a curved edge, and 3D is a more curved edge that fits the screen.

 

It can be understood in this way that the larger the number before the curvature D, the higher the curvature and the wider the coverage. Therefore, for curved screen mobile phones, the coverage rate of 3D is greater than 2.5D and greater than 2D, and 3D can truly achieve full coverage.

 

 

We often see gimmicks such as 8D, 9D, and 100D screen protectors from brands to show that their mobile phone screen protectors are more rigid and of better quality. In fact, this is an irregular statement, or the reference of this number is actually not significant.

 

 

The strength mentioned here is related to the quality of the screen protector of the mobile phone, that is, whether the material of the screen protector is hard enough, whether it is resistant to falling, and whether it can better protect the screen of the mobile phone, and these are basically composed of screen protectors. determined by the material. At present, the common mobile phone screen protector materials on the market are lithium aluminum, soda lime and high aluminum glass. Among these three materials, high aluminum glass is the best, with high pressure resistance, high temperature resistance, good permeability and strong pressure resistance. , Compared with other materials, high-alumina glass is more resistant to fabrication. Of course, mobile phone screen protectors are already very mature products, and other materials are not bad.

 

 

 

The oleophobic layer should be familiar to everyone, and its meaning will not be described in detail. Let me talk about its function. The oleophobic layer can make the screen less prone to fingerprints, easier to clean, and smoother when operating and sliding. However, this thing will wear and tear continuously with the use of time, and finally disappear slowly. At that time, it will not be able to play the role of anti-fingerprint. At present, the common oleophobic layer spraying processes include machine spraying, plasma spraying, and vacuum plating. And electroplating, the last three spraying processes are all good, feel better, and are more durable.

 

The above is the difference between mobile phone screen protector.
