Based on the sketches that accompanied the patent filing (below), the device will have three separate screens, which can expand and unfold into a tablet-sized screen. The process can be reversed to bring the size down to the level of a smartphone, by folding it in a similar manner as you would a tri-fold wallet.
It looks like Samsung will also be developing software capable of taking advantage of the unique size and layout of the new device. Chances are this software will be deployed as an app, rather than a full operating system or suite of software.
