Abstract |
OLED outcoupling efficiency is limited by several factors, one major factor is the limitation caused by internal reflection of light with the interface between organic layers including the anode and glass substrate. Here, we approach this problem by adding a fairly exotic material to the OLED setup, which strongly scatters light. We expect the scattering to weaken total internal reflection and increase outcoupling efficiency. Through measurements, we compare the out coupling efficiency of the control OLEDs and the OLEDs with the scattering layer. Finally, we analyze the potential for increased outcoupling efficiency and, later, industrial application. After analysis we find a 1-2% increase in efficiency without accounting for error.
