Sony Demoes "Rollable" OLED Technology

Japanese manufacturer Sony has showed a prototype of an OLED (Organic Light Emitting Diode) that is so thin - 80 microns - that it can be rolled around a pencil and could herald a new generation of ultra flexible displays.

The display has a resolution of 432 x 240 pixels (that's 121 pixels per inch), a screen diagonal of 4.1-inch capable of displaying 16 million colours, a contrast ratio of 1000:1 and produces 100 cd/m2 of brightness.

This is still low compared to say a mobile phone display such as the HTC Desire whose 3.7-inch screen can show 800x480 pixels. But then, OLED are positively power sippers, ultra light, produce outstanding pictures and are self-luminous (i.e they don't need backlight).

This is only a prototype but the fact that Sony has already launched two "big" OLED televisions over the last two years and that there are countless numbers of products that come with OLED screens means that the technology is here to stay.
