P‐194: Control of the Viewing Angle Dependence by Inserting of Scattering Layer on Microcavity OLEDs

Abstract

In this study, we present viewing angle independent microcavity OLEDs by using scattering layer (SL) and planarization layer. Compared to a device without SL, device with SL had an angular emission profile like lambertian. Also device with SL showed a less color coordinate and spectra shift. Then two devices showed similar EQE, which means there were no light loss.
