Samsung's latest patent details a self-healing oleophobic coating for smartphone displays

Samsung's latest patent details a self-healing oleophobic coating for smartphone displays
Samsung Galaxy S9

These days nearly every modern smartphone makes use of an oleophobic coating on top of the display glass. This not only provide a sleeker surface which in turn results in an added protection against scratches – the lack of friction helps objects just slide off the surface – but it also helps prevent fingerprint marks. 

Despite the popularity of these coatings, though, Samsung is seemingly not content with the one that it currently uses and has now been granted a new patent related to a modified formula. This new development will allow the brand’s next coating to self-heal when required. Thus, whenever applied on to a device’s display, an added layer of protection against scratches will be provided. Also, due to the self-generating characteristics, the coating should also prevent fingerprints for longer periods of time. What does remain unclear at this point, though, is to which extent the coating can heal itself.

Currently, Samsung is yet to make an announcement in regards to when its new coating will make its way to devices. In fact, the company may actually never make use of the technology as, for now, it’s simply a patent. However, with smartphone displays continuing to increase in size and Samsung’s foldable Galaxy F also in the pipeline, the new self-healing coating may be exactly what the brand needs to keep its displays looking like brand-new for longer periods of time.

This is good news, fixing on of the shortcomings of their phones. I like Samsung phones, but their oleophobic coating sucks, it used to always start wearing off after the 1st 2 months of owning my phone, especially where my thumb usually rest on or swipe on the screen.

I totally agree, I get a new galaxy every 6 to 12 months on Jump on demand and the coating always starts wearing off anywhere between 2-6 months. My current phone, Galaxy S9+ got bad after 2 months. I'm always cleaning it and still I always see greasy marks on screen when there is a white background on something. So annoying.

What sucks even more, is that if you wipe your phone with a wet wipe, or dare to use the phone in a swimming pool, even for once, say goodbye to the oleophobic coating. Your phone will always look dirty and nasty after that. It quite the opposite experience with other phones, none of those things have ever affected the oleophobic coating.

I would think certain types of oils or cleaners may cause it to break down sooner. I don't use cleaners on my screen. On occasion I use pledge which gives a coating of its own. Just clean only with a microfiber damp cloth. And try not to use it with greasy fingers.

This x1000. I'm pretty sure my S9+ never even came with an oleophobic coating because it's been showing grease smudges since day 1. My 2 year old Axon 7 still has 100% of its coating :/

That's why we need phone reviews after 2-3 months post releasing a phone. These sort of issues won't be noticed after 1 week of using a device.

What's weird though is if i pour some water drops on my screen they do stay together so idk i guess i have some left just not enough to keep fingerprints and grease off?

Is there a way to specifically tell its wearing off? I've not heard of that happening to any phone. I'd like to know how to check for that. I have 3 older Samsung devices, and I have not noticed that and would like to know how I can tell. Also consider how you may clean your glass, as some cleaners also may take off the coating which is very thin to begin with. In most cases you only need a microfiber cloth and no chemicals. Don't use glass cleaners because its not real glass. Just a slightly damp cloth is enough.

I only use a microfiber after what happened to my S7 Edge, and it still wears off. And you cant tell by blowing on your screen, you'll easily tell where the oleophobic coating ia gone.

I have never had a problem but I do always use a screen protector from day one. This is a good step forward though.

I've had my Note 8 since release and I am jealous of you guys! I hate the oleophobic coating and have tried to remove it myself. Screens still so slick I have trouble selecting links or long pressing apps on the homescreen to move them. I've had it with no screen protector for about a year, would love for it to wear off already.

Removing the coating would be the worse thing ever. Prints and scratches would ruin the display. Just use a "matte" screen protector. Better known as the plastic/vinyl films. I suggest an InvisiShield. IQ Shield and ArmourSuit on Amazon are brands I use most and they work great!
