A Samsung patent for rollable OLED screen has appeared on the World Intellectual Property Organisation database. It looks like the South Korean company has been working on a scroll-like device, with the display wrapping around a central core.
Securing the display are strong magnets located around the perimeter of the display or at the leading edge. Alternatively, the patent proposes a cylindrical body with a roller in the core to pull-in the screen for storage when not in use.
From the looks of it, the central core will also possess a fingerprint sensor for releasing the display from the housing. The patent drawings don’t quite show any alternative methods for access, like say a keypad for a PIN, but that doesn’t mean that Samsung isn’t thinking about it.
The original patent application was filed all the way back in 2016, with approval being received in June 2017. Which indicates that Samsung has been sitting on this idea for a while. That said, a lot of ideas are patented simply to prevent other people from building the product first.
