Foldable phone
smartphone type introduced in 2019
A foldable phone (also known as a foldable smartphone) is a smartphone that can be folded. Some foldable phones use multiple touchscreen panels on a hinge, while others use a flexible display.
Concepts of such devices date back as early as Nokia's "Morph" concept in 2008, and a concept presented by Samsung in 2013 (as part of a larger set of concepts using flexible OLED displays). The first commercially available folding smartphones with OLED displays were sold in November 2018.
