Abstract

In this study, we report OLEDs with improved light‐extraction efficiency by applying random nanopillar light‐extraction structures (rNPLES). OLEDs containing low‐temperature mask‐ free process‐based light‐extraction enhancement structures improved by 1.16‐fold depending on plane ratio with non‐ patterned initial polymer thickness. OLEDs with optimal rNPLES also showed a 129% improvement in external quantum efficiency and a 132% improvement in power efficiency.
