Flexible OLED has been around for a while, but rubbery OLED is a whole new concept. Researchers in Tokyo have developed prototypes that can be shaped and stretched in a variety of ways, from a human face to a complete sphere. The displays are produced by applying a thin layer of fluor-rubber material to carbon nanotubes. The resulting stretchable material is thinner than LCD and plasma, and uses very little power.
For now, the prototypes are monochromatic with a resolution of a whopping 256 pixels. However, it can be folded a thousand times without degrading the quality.
