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