Paper Abstract
Efficient light extraction from organic light emitting diode (OLED) is challenging and efforts are being made to come up with efficient & cost effective outcoupling techniques. We demonstrate 50% EQE entitlement from solution processed white OLEDs compared to 33% EQE observed in devices, implying that there is plenty of room to improve the efficiency of white OLEDs. We present challenges in efficient light extraction from solution processed OLEDs that need to be overcome to close the efficiency gap. We also demonstrate a novel characterization technique that is effective in estimating the light extraction efficiency of outcoupling films and can expedite the selection and optimization of various light extraction approaches without the need to build OLEDs.
