Oleophobic coating, what is it in the phone, how to save, replace

Oleophobic coating in the phone - what it is, why you need it, how to save it

Often in the process of choosing a smartphone in stores (both in the “ground” and online) you can see on the price tags or in the description the following feature – oleophobic coating, what is it in the phone – we will understand in today’s publication.

The difference - there is an oleophobic coating and no

Display protection

There are many interpretations of the concept, but the closest to reality is the translation from Latin:

  • Oleum – oil;
  • Phobos – fear, fear.

If you combine the two words, then the picture starts to form in your head – oleophobic coating repels dirt, grease, sweat and other unpleasant components. After all, in the process of using a smartphone, our hands are not always clean, and in the hot season we also get sweaty. And someone likes to eat and then use his fingers to run over the screen (without wiping them beforehand).

As a result, when you own a budget mobile device, spots and stains quickly appear on the display. They not only spoil the visual impression of the appearance of the gadget, but also interfere with viewing. It is enough to use a special wipe for cleaning, but it is not always available.

Greasy fingerprint traces

Almost all modern phones of the middle and premium class are equipped with an additional oleophobic layer, located on top of the glass. This does not mean that you will be 100% protected, just traces will remain much less, they will not be so noticeable. Yes, and remove them realistically with one movement – you can sleeve, T-shirt, etc.


The principle of action

With the effect solved, but the question remains open – how does it work?

Oleophobic coating for smartphones is an ultra-thin layer (its thickness is only a few nanometers), whose composition is formed from silicone, alkylsilane and liquid-solvent. The film is formed not by direct adhesion to the surface, but by spraying. That is, the above ingredients are mixed, vaporized, and evenly sprayed over the screen.

Oleophobic protection demonstration

If you take two phones in your hands – coated and uncoated, you can feel the difference by touching the screen. If there is only one phone, you can hardly make out anything by touch. Unless you actively use it for about ten minutes and then swipe the tissue once from top to bottom. If there is no trace left, it means that this layer is present on the display.

By the way, for such a useful chip we have to thank the company Apple. They bought the patent for the invention from a couple of German scientists. Then they made their own adjustments and started applying it to their iPhone 3GS phones.


How to extend the life of the oleophobic coating?

Many people wonder if it is realistic to buy it. You can buy it only in a set with a protective film or glass. That is, it is not sold separately. If you carefully read the previous section, you understand why.

The more intensively a person uses his mobile gadget, the faster the coating wears out. Especially often with this face inveterate gamers, who are very actively dragging their fingers on the screen.

The second reason for premature erasure is the failure to use the case. In this case, when you put the smartphone in your bag, pockets, there is friction between the surfaces, destroying the oleophobic film.

Wiping the screen with a napkin

Obviously, it is possible to save it, to extend the life by moderate use. Also, do not clean the display with wipes that contain alcohol. The optimal solution is a microfiber. You can also buy special cleaning products in stores.

And the last tip – try not to leave the phone “face up” under direct sunlight. Ultraviolet light is also capable of slowly but surely destroying the coating.
