Abstract

We report the highly efficient organic light-emitting diodes (OLEDs) having the nano-scale random light-extraction structure (NsRLeS). The demonstrated NsRLeS realized the highly improved light out-coupling, resulted improved electroluminescence efficiencies without introducing the spectral distortions at any viewing angles. The OLEDs having the developed light out-coupling enhancement structure showed >90% improved power efficiency and >50% improved external quantum efficiency. The NsRLeS was fabricated by simple and easy process enough to apply on the mass production of the large scale OLEDs applications.
