ORGANIC LIGHT-EMITTING DIODE, ARRAY SUBSTRATE AND PREPARATION METHOD THEREOF, AND DISPLAY DEVICE

摘要

The present invention relates to an organic light-emitting diode, an array substrate and a preparation method thereof, and a display device. The organic light-emitting diode comprises an anode, a cathode, a light-emitting layer disposed between the anode and the cathode, and a hole injection layer disposed between the anode and the light-emitting layer, wherein the hole injection layer is provided therein with metal nanoparticles, and the frequency of a localized surface plasmon resonance of the metal nanoparticles is matched with the emission wavelength of the light-emitting layer. As the organic light-emitting diode is doped with metal nanoparticles in the hole injection layer and the resonance frequency of the localized surface plasmon of the metal nanoparticles is matched with the emission wavelength of the light-emitting layer, the metal nanoparticles are allowed to generate localized plasma resonance with photons, so that the light extraction efficiency of the organic light-emitting diode is enhanced.
