Samsung is Working on a Self-Healing Oleophobic Coating for Smartphones

With the display being one of the more important components in their flagship phones, Samsung is enhancing the protection standards of these devices by introducing a new type of oleophobic coating.

The oleophobic coating consists of a thin layer applied on top of a smartphone display to keep fingerprints off. It is now an inevitable addition in most modern smartphones, which is why it is not mentioned too often.

It has also been a point of discord between Samsung and its users in recent times, with the latter being unsatisfied with the quality of the applied material.

Due to that issue, Samsung has gone out of its way to patent a self-healing oleophobic solution which regenerates itself if a part of it is scratched off by an accident. The coating could eventually be produced by Samsung itself for its curved display phones and might be seen in other smartphones.

It’ll go on top of the regular Gorilla Glass 5 layer, which is also included in Samsung’s phones. Another reason for this sudden addition could be the bendable Galaxy X smartphone, which is set to release later this year.

G-Flex and the Note 8

At one point LG made a phone with a self-healing display (the G-Flex) but since then the company hasn’t included it in any other smartphones so far. It’ll be interesting to see if LG comes up with something similar to rival Samsung.

Last year, we heard reports of oleophobic coating issues in Samsung’s Galaxy Note 8 flagship, which apparently saw its coating peel off from the sides of the smartphone where the display’s curvature began.

In such instances, the fingerprints in those areas became much more visible. There were a few whispers of the Galaxy S9+ facing the same issues as well, but nothing major or concrete so far.
