An organic light-emitting diode (OLED) developed in Germany has the potential to produce the same quality of white light as incandescent bulbs but with power efficiencies considerably better than even fluorescent lighting. The prototype OLED could emerge as an ultra-efficient light source for displays and general lighting, says Sebastian Reineke, who led the research at the Institute for Applied Photophysics, in Dresden, Germany. The long-term goal is to fabricate the device using conventional low-cost roll-to-roll printing.

Stretchable Displays
An elastic conductor makes possible cheap, conformable displays.Researchers at the University of Tokyo have moved a step closer to displays and simple computers that you can wear on your sleeve or wrap around your couch. And they have opened up the possibility of printing such devices, which would make them cheap.
