UDC shows off rollable OLED screen

Today, at the Flexible Displays and Microelectronics conference in Phoenix Arizona, Universal Display Corporation demonstrated a folding 4" active-matrix display. The display is 0.1 mm thin, weighs six grams (not including packaging and pixel drive electronics) and can show full color images, along with full-motion video.

The metal foil backed device initially will have military applications. On the consumer side, the display technology may make its way into future portable and wearable electronics. According to the company, the display also could be a part of future communications devices where users "unroll a thin, metal screen from a pen-like device".
