OLED Operated by 1.5-V Battery Produces Bright Emission Equivalent to a Typical Display

Various properties of organic light-emitting diodes (OLEDs) have been optimized, including current to photon conversion efficiency. An external quantum efficiency exceeding 20%, with internal quantum efficiency of 100%, has been achieved owing to the development of thermally activated delayed fluorescent and phosphorescent materials that manage the spin of excited states.
