Organic light-emitting diodes (OLEDs) could be the thin-film display and lighting technology of the future, but for lighting applications their diminishing efficiency at high brightness is a problem, the underlying cause of which is unclear. In a comprehensive analysis of phosphorescent OLEDs, the authors find, in contrast to previous conclusions, that in these devices triplet-polaron quenching (TPQ) is the dominant process behind the efficiency roll-off. This style of analysis and the understanding it brings could provide a breakthrough in solid-state lighting performance.
