Sony has unveiled an ultra thin flexible organic light emitting diode (OLED) display. The OLED display is a mere 80 µm (micrometers) thick, which is less than a strand of hair. It measures 4.1 inches and can be rolled around a cylinder. A prototype measuring 2.5 inches had been unveiled as early as May 2007. However it had only a fraction of the flexibility of the newly launched gadget.

The OLED has a resolution of 121 pixels per inch (ppi) and is capable of displaying 16,777,216 colors. The display is OTFT driven and has a contrast ratio of less than 1000:1. The OLED is capable of being rolled up around a cylinder of radius 4mm. The display is fully functional when rolled and stretched, which is the first of its kind.
