Abstract

Novel microlens array architectures for enhanced light outcoupling from light emission are provided. Organic light emitting devices (OLEDs) that include an outcoupling layer including these novel microlens array architectures and method for fabricating such OLEDs are provided. These devices may be used to provide OLEDs with optimized light extraction.
