If you use a touchscreen smartphone for your daily functioning, with almost one hundred percent certainty, its display is equipped with an oleophobic layer. Thanks to this, your fingers slide perfectly on it, it is not so easy to scratch it and dirt or fingerprints do not stick to it as much. After some time, however, this protection wears out and your display begins to show slightly worse properties, which you can notice, for example, just by the deposition of your fingerprints. And this is exactly what Samsung would like to do in the future.
The South Koreans recently registered a new patent, which has only one goal – to significantly improve the oleophobic layer and, above all, its service life. The oleophobic layer on future Samsung smartphones should be chemically enhanced to be able to repair itself. Simply put, it could be said that thanks to this improvement, the display should have perfect characteristics even after two years of continuous use. However, it is not at all clear at the moment how far along Samsung is in the development of something similar.
We can't be too surprised at Samsung's efforts in the area of the oleophobic layer. It is precisely his phones whose displays are considered to be the absolute best worldwide and regularly win prizes for the best smartphone screens in the world. By improving the protective layer, Samsung would raise their level again and ensure their perfection for a much longer period of time than is the case so far. However, since it is still only a patent, its realization is not in sight. But who knows.
