Abstract

Organic light-emitting diodes (OLEDs) have led to the rapid growth of the next-generation display technology due to high luminance efficiency, vivid color, and high contrast ratio, thereby expanding their applications from conventional mobile or TV displays to virtual reality (VR)/ augmented reality (AR) displays. For more effective light extraction, implementing nanostructures onto metal electrode layer of OLEDs as a future display technology has been demonstrated by use of excitation and out-coupling of the surface plasmon-polariton modes (SPPs). In this work, we propose a high resolution OLEDs based on plasmonic patterned nanograting array (PNA) that induces a plasmonic effect on OLEDs through the nano-patterned organic emission layer by applying E-beam lithography on the fabrication process without deterioration of intrinsic physical/photoelectric properties of organic layers.
