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.
