We have not known since today that Samsung has a lot of patents for new devices using foldable or rolled displays. Here is one of them, also containing biometric technology known to us.

Samsung has patented a foldable OLED display with magnets and a fingerprint reader. It is true that similar information from documents should always be treated as a curiosity, but one thing is interesting. Many information and even working prototypes have already appeared on the subject of collapsible (or wound on a roll) displays. Despite this, there are no reports that a similar solution would soon hit the market. The important information mentioned by me is the fact that the patent distinguishes a fingerprint reader that would activate the display development. It may mean that Samsung is not planning to get rid of this technology too quickly and will not put everything on one card in the future, like Apple when transferring from Touch ID to Face ID.

Besides, the patent indicates that the display would be rolled up / unwound and held, thanks to magnets. In contrast, one of LG's previous patents assumed a similar solution, but with the use of a small rotary motor. Documents also indicate two types of housing made of metal – cylindrical and square. Of course, for now it's just an idea that probably will not go to any device in the coming months. However, everything can change in the perspective of the next few years. If I had to think more about all this, I would say that this is how our smartphones can present themselves in the future.

Let's point out that we are currently choosing two extremes. On the one hand, we care about the maximum miniaturization of subassemblies, and on the other hand we prefer devices with a larger display. Everything, however, has its limits, and the expandable display enclosed in a small enclosure is a quite interesting idea that can become a reality in a few or a dozen years. Perhaps a similar device will be seen at the upcoming CES 2018. Source: LetsGoDigital
