Abstract

Organic light-emitting diodes (OLEDs) have already been proven in display applications and show promise as the next-generation solid-state lighting technology for general illumination. A major barrier to the adoption of OLEDs for solid-state lighting is the efficiency roll-off at high brightness, which occurs at much lower current densities for OLEDs than their inorganic counterparts, in large part due to the quenching of excitons. We discuss strategies to mitigate this efficiency roll-off through management of excitons in both white and monochrome devices, including the use of phosphorescent as well as thermally activated delayed fluorescent emitters. Successful high-efficiency devices are used as case studies for how to effectively manage excitons.
