Paper Abstract

High efficiency OLEDs based on phosphorescent, thermally activated delayed fluorescent (TADF) and fluorescent emitters will be presented. We will show that EQEs over 60% is achievable if OLEDs are fabricated using organic semiconductors with the refractive indices of 1.5 and fully horizontal emitting dipoles without any extra light extracting structure. We will also show that reverse intersystem crossing RISC rate plays an important role to reduce the efficiency roll-off in efficient TADF and fluorescent OLEDs and a couple to methods will be presented to increase the RISC rate in the devices.
