ALWAYS scratch the smartphone? Samsung has developed a
revolutionary display that repairs itself. The so-called
"self-healing" screen repairs scratches by itself and makes your
device look as good as new. Scratchy smartphone screens can be very annoying, but
will soon be a thing of the past. The technology is disclosed in a Samsung
patent issued by the World Intellectual Property Organization. In the patent
Samsung describes how customers regularly suffer from tiny screen scratches -
and also fingerprints. The solution is to create a protective layer on a
smartphone screen that can repair itself and even fend off these nasty finger
oils. Smartphone screens are usually covered with tempered glass.
Samsung's own phones are equipped with sturdy gorilla glass built
by a company called Corning. It's designed to be really tough, but it's not a
catch-all solution. "There is a need for a protective material with
improved properties that can be applied to an electronic device," Samsung
explains in its patent application.
Samsung describes its concept solution - a thin film that
lives on the screen of your smartphone and can even be applied to foldable
phones. "The film can be self-healing after scratching and has excellent
flexibility and can therefore be applied to a flexible device and the
like," writes Samsung. The "flexible devices" bit is important
as Samsung expects to launch its own foldable smartphone in early 2019. The
patent states that the film would consist of "polyrotaxane, polyhedral
silsesquioxane and fluorinated (meth) acrylic". Unfortunately, it is not
described exactly how these compounds would heal the screen. However,
self-healing surfaces are not exactly new - and we've even seen them on
smartphones.
Launched in 2013 and 2015, the LG G Flex and G Flex 2
smartphones came with self-healing wheels. LG ignored the exact background of
the technology, but suggested that this was due to the hydrogen atoms built
into the back of the phone. In an interview with TechnoBuffalo in 2015, it said
that hydrogen atoms tend to ally themselves. So, when scratches are made, these
atoms revert to their original point, effectively curing minor scratches.
Unfortunately, the tech did not work for bigger cuts. It is very likely that
Samsung's self-healing screen cannot repair major scratches.
And to refuse fingerprints, Samsung wants to provide its
protective film with an Oleophobic layer. This is a special type of material
that repels oil - just as hydrophobic materials repel water. This means that
finger oils cannot stick to the smartphone glasses, making the screen much
cleaner. When do we see this technique on a telephone? At the moment, it's just
a patent, which means there is no guarantee that it will ever come on an
available Samsung handset. But the fact that Samsung mentioned foldable phones
in its patent could mean it will end up on next year's foldable Galaxy X
smartphone. Alternatively, we could see Tech on the next year's Samsung Galaxy
S10 smartphone, which is also expected in early 2019.
