We've seen what Samsung has done with a foldable display, but a newly discovered patent suggests the company is exploring the idea of stretchable displays. The diagrams seen on the patent filed by Samsung with the US Patent and Trademark Office show the screen can be increased at will thanks to a moveable backside plate. The smartphone seems to sport narrow sides and a wider chin.
The patent describes a sensor capable of recognizing any change in touch input so the phone can calculate how much to increase or decrease the screen size. If Samsung decides to make this into an actual product, it can be useful for media consumption or gaming, among other uses.
