Launching just before Mobile World Congress this year, Samsung got the jump on its major competitors with the reveal of the Galaxy Fold.
But the book fold styled device that was shown to the press is only one of a number of designs that the South Korean company has been working on.
With folding smartphones set to be one of the key hardware battlegrounds over the next few years, what other options were considered?
Samsung has published a number of patents regarding foldable display technology over the years, including mock-ups of potential devices. The team at Lets Go Digital has taken the details from these patents to put together a look at a historical design that could, given circumstances, become an actual Galaxy device in the future:
There are 25 sketches attached that show the mobile phone from all sides. The foldable phone from Samsung has a large flexible screen that can fold twice. Once expanded you have a tablet size screen at your disposal. If you fold the device, the screen remains on the outside. You curl the screen around the housing. The entire device then consists of a display, both the front and rear.

The patent (PDF) was filed two years ago, and a published patent is no indication that a technology will reach the market. But Samsung has a long history of experimenting with technology and patenting designs for commercial exploitation (just as Apple has done with its holding technology).
With more than one folding handset expected to be launched this year, I doubt all of them will have the same design as the Fold.
