We have been hearing rumors of these for a while now but Samsung has finally come clean with their YOUM flexible OLED displays at CES this year.
Although no actual product using these displays have been announced so far, Samsung did showcase three applications of it. One of them had the design of a regular smartphone, with just the right edge being bent downwards. This bent strip displayed content in landscape mode, so that even if you have the phone in a case, you can see notifications and such from the side at a glance.
The other two designs included a device that couple be folded up in the middle and another one where the display could be rolled up and retracted.
Thanks to the flexibility of the display, we might finally start seeing some disruption in the design of smartphones, which have turned into boring slabs over the past years. The flexibility also means that these displays are a lot more shock resistant. It remains to be seen what product Samsung would choose to put it in first.
