By now, the mobile phone screen protector can be mainly divided into two categories. One is a variety of screen protector made of glass, such as privacy screen protector, anti blu-ray screen protector etc., this sort of screen protector has higher strength and hardness, touch like the mobile phone screen itself. Second, screen protectors that are made of plastic, like the NTPU screen protector.

Screen protector

The material of the tempered screen protector is very similar to the glass on the screen of the mobile phone, while the Mohs hardness of the tempered screen protector is between 6 and 7, far higher than that of metal. Therefore, the hand feeling and scratch resistance of the tempered screen protector are very good. But now many mobile phones use curved screen design, and there is bending treatment on the screen edge of mobile phones, which has higher requirements on the edge process of tempered glass screen protector. If the edge is not well treated, there will be a white edge after installation, no beautiful in outlook. The plastic film is very soft, so it can be easily bent to fit the edge of the mobile phone, but after all, the feel of plastic is far less than glass. Second, the Mohs hardness of plastic is between 2 and 3, so it can be easily scratched by almost anything around it. So how to choose a better hand feeling and better fit tempered glass screen protector is important.

Tempered screen protector

There are there layers in a tempered screen protector, the top layer is a sparse oil layer,which play an important role in hand feeling and anti-fingerprint. The middle layer is tempered glass, which affects the appearance of the mobile phone and the touch sensitivity. The last layer is adhesive, which is important for fitting the screen protector to the mobile phone and keeping a high light transmittance.

Let's start from the top oil drainage layer, which is a waterproof material that repels water and oil. It makes the sweat and oil on our fingers not easy to adhere to the screen surface. For fingerprint resistance, oil drainage is the most important part, the mobile phone screen has oil drainage layer too.

Anti-fingerprint effect

The oil drainage coating process can be mainly divided into manual spraying, mechanical spraying, plasma spraying, vacuum evaporation.

Seeing from the name, Manual is to brush or spray the oil layer on the screen by hand. The effect of this method is the worst. It can last few days, is a waste of money if you use this method on the nano coating you bought.

Machine spraying is machine instead of manual spraying. In this way, spraying is relatively uniform, but it is still not durable.

Plasma spraying is to clean the glass with plasma arc before spraying the sparse oil layer, change the surface characteristics of the glass, and then spray the sparse oil layer, so that the sparse oil layer can be better combined with the glass and become more durable. Nowadays plasma spraying is widely used.

Vacuum plating and vacuum evaporation are to put the glass and anti-fingerprint oil in the vacuum environment, and the sprayed anti fingerprint oil will closely integrate with the glass in the high temperature and vacuum environment. This coating is not only more uniform, higher density, but also very solid. The mobile screen usually uses this method to smear the oil layer, it means that it is the fingerprint oil of plating, and it is the most worth buying.
