New Sony OLED Display Can Roll Into Cylinder

Sony recently debuted its latest in OLED technology: a 4.1-inch screen that's only 80 microns thick. The super-flexible display can roll up into a cylinder just 4mm in diameter while still showing moving images at 432×240 resolution. Instead of brittle integrated circuit chips, the screen has an on-panel gate-driven circuit — a world first, according to Sony. That innovation would allow everything but the power supply to roll and flex in applications.
