Will screen protector remove oleophobic coating? Nowadays, many mobile phones have oleophobic layers to reduce the stains on the phone. If we usually use the mobile phone screen protector, will it remove the oleophobic coating? So let us to understand what is the oleophobic layer. What is the function of the oleophobic layer?

What is the oleophobic layer?

We also called oleophobic coating, or hydrophobic coating. As the name suggests, it is a composite coating, which is often coated with nano-silica as a raw material or a nano-scale fluorine-containing material. This coating combines the characteristics of light transmission.

In the field of mobile phones, this coating is mainly used on the screen of mobile phones. It is true that the screen of the mobile phone needs to be very transparent, so it should be as thin as possible and does not affect the display screen of the mobile phone. Its function is to make the phone screen easier to clean and not easy to leave fingerprints and perspiration. At the same time, some mobile phone manufacturers will improve the screen sliding experience when choosing a coating, which makes the screen coating smoother and more natural.

Its principle is not complicated. The contact area of the layer with oil or water is relatively small (compared to a simple glass layer). It originates from a special nanostructure, so the water droplets are like the top of the blade, and it is not easy to attach to the phone screen which it is the so-called "cleaning effect" of the plant leaves.

As can be seen from the picture, the new mobile phone with oleophobic cpating and the mobile phone that has been almost wiped out by the oleophobic coating for a long time are really different, and the water droplets will spread out.

The misunderstanding of the oleophobic coating

There has been a lot of debate about the oleophobic layer. The focus of the debate is that a heavyweight mobile phone of a heavyweight brand has been exposed without oleophobic layers. In fact, this feature is not required, and there are no regulations or mandatory requirements. Mobile phone manufacturers use oleophobic layers on high-end products to provide a better used feeling.

This configuration is not absolute, not that it must be good. It is true that the oleophobic layer can make the glass perform better, but this performance is not lasting. Because the coating is very thin, it will gradually wear out in daily use. Generally, there will be nothing left in a few months. So the experience is very good at first, and you will find that mobile phones are getting more and more dirty on the screen after few months. In addition to the normal wear and tear of the mobile phone screen, there are many traces of scratches and friction that are invisible to the naked eye, which will cause the oleophobic layer to fall off.

So how to better protect our mobile phone?

First of all, if the original factory mobile phone has no screen protector and comes with an oleophobic layer, then the user can use it with confidence, and the screen can be cleaned well until the oleophobic layer is worn out. If the phone has a screen protector at the factory, it is best not to remove the screen protector directly, unless you are not used to the feel of the screen protector. Nowadays, the high-quality screen protector often has a certain oleophobic effect, and even the coating is attached, to protect our mobile phone screen from scratched.

If you feel that the experience of the mobile phone has been affected, you can also use the popular tempered glass screen protector or high-quality screen protective film. As long as you pay attention to the screen of the mobile phone, it will not be scratched, and it will not be placed with hard objects such as keys.
