Researchers from Microsoft and the University of Applied Sciences Upper Austria developed a new smartphone case prototype called FlexCase -that adds a secondary flexible E Ink touch display.
FlexCase enables users to interact with their phone in several ways - including bending it to flip pages, zoom and navigate. The basic concept is similar to OLED-based prototypes demonstrated in the past. . Back in 2011 Nokia demonstrated an OLED concept called the Kinetic, and in 2015 AUO demonstrated a bendable 5" AMOLED display that includes a film-type touch sensor.
