Frequency‐dependent, high‐performance organic electroluminescent devices driven by alternating current (AC) are demonstrated through impedance matching of the device to the driving source by D. L. Carroll and co‐workers on page 8133. The device may allow for specific advantages, including elimination of rectifiers while integrating into 110/220 V and 50/60 Hz AC power sources, reduced Ohmic‐heating‐based failures at color component interfaces, and greater manufacturing tolerances over large areas.
