Color-tunable organic light emitting diode based on photonic crystal structure

Abstract

Disclosed is a color tunable organic light emitting diode based on a photonic crystal structure. The color tunable organic light emitting diode includes at least one substrate, an anode and a cathode provided on the substrate, a photonic crystal layer provided between the anode and the cathode, and at least one emission layer provided on the photonic crystal layer, wherein a plurality of patterns are formed by a plurality of photonic crystals included in the photonic crystal layer, the photonic crystal layer is configured to be stretchable by a strain applied to the photonic crystal layer in a diagonal direction, and the at least one emission layer is configured to emit light of a specific color according to the plurality of patterns deformed by the strain.
