Ole OLED!

Related to the topic of e-paper is that of flexible displays (e-paper is essentially a flexible display). Several technologies are being developed to do different things with e-paper, but OLED (organic light emitting diode) is one technology that has the potential to add rich media capabilities (like video and animation). (One other big e-paper technology--E-Ink--is strictly a mechanical process that doesn't easily lend itself to the fast refresh rate required by video.)

Anyway, Gizmodo today has an item from the Fifth Annual Flexible Displays and Microelectronics Conference (yes, there actually is such a thing---wish I had known about it). There was a

prototype of a full color active matrix OLED display from Universal Display Corporation. The display is 4-inches diagonal, .04-inches thick and .2 ounces, and runs full motion video using metal foil, which the company says helps thermal and mechanical durability.

And it rolls up. Neat.

Check out the image at the link--it does indeed roll up into a pen-like object.
