The World’s Most Efficient Flexible OLED

Researchers at the University of Toronto just announced that they have developed a new way to produce flexible, plastic-based OLEDs that are inexpensive and as efficient as OLEDs made with glass. Watch an interview with the researcher after the jump.

The team at University of Toronto paired a flexible plastic substrate with a 50-100 nanometer thick layer of tantalum oxide — an optical coating material — before layering the device with the film of organic compounds that emit light. The tantalum oxide was able to boost the charge of electricity and therefore provide a brightness generally not available in plastic substrate OLEDs.
