The organic light emitting diodes—known widely as OLEDs—that create vibrant smartphone displays could illuminate rooms, but current designs burn out too quickly at the high brightness needed for room lighting. A new approach overcomes this tradeoff by building OLEDs on a corrugated surface, packing more emitting material into a given lighting panel area to produce the same amount of light while operating the OLED itself at lower brightness.
