The demo video only gives us a glimpse of the front of the device and the screen seems to wrap around the phone and roll up from the bottom. As far as prototypes go, this concept seems to be on the “operational” end of the spectrum – at least there are battery and mobile indicator icons on the screen. The rolling display is a flexible OLED panel, measuring 6.5 inches when extended and retracted to “just over” 4 inches.
