At a recent press event, tech giant and smartphone manufacturer Samsung demonstrated a combination smartphone/tablet screen that folds to create two different screen sizes. The screen is named the Infinity Flex Display. Samsung has said that the screen will be used with a new smartphone model scheduled for release sometime in 2019.  

Samsung is far from the only company that has been developing a foldable device screen, but they were the first to show a prototype of such a screen. And while it does offer two different options for screen size, the prototype device was also very thick as a result, making it run counter to attempts in recent years to make smartphones as thin as possible.

Certain analysts have predicted that folding phones will ultimately be unpopular with the public, similar to 3D televisions or VR headsets.
