That's Organic Light Emitting Transistor, tech that researcher Michele Muccini at the Institute of Nanustructured Materials has just proven can be between two and 100 times as efficient as OLED.

Last year Hewlett-Packard, along with a team of scientists from UCLA, proved the ability to make a switch that could be turned off and on, like a transistor, out of a single organic molecule called a catenane.
