Foldable displays come into existence by making them as thin as possible and using flexible materials. As the display can be both folded and unfolded, product size can be minimized, which opens up an array of application opportunities for mobile or IT devices.

A foldable display is a type of flexible display that can be folded and unfolded like paper.

The foldable display has the thinnest design possible to be folded and unfolded and adopted a cover window, the UTG, made up of bendable materials on top of the flexible OLEDs that feature flexible materials at the same time. 

Foldable displays available at the moment come in two types, which are inward (with the display folding into the interior of the device) or outward (with the display wrapping around the device).
