Abstract: The present disclosure discloses a pixel defining layer, a display substrate, and manufacturing methods thereof, and relates to the field of display technology. The pixel defining layer includes: a defining layer body, and a temperature-sensitive polymer layer located on an inner side surface of the defining layer body. The temperature-sensitive polymer layer has a solution temperature threshold, and the hydrophilicity and hydrophobicity of the temperature-sensitive polymer layer are different under temperatures of the temperature-sensitive polymer layer higher and lower than the solution temperature threshold. By changing the temperature of the temperature-sensitive polymer layer to be higher or lower than the solution temperature threshold thereof, the temperature-sensitive polymer layer is converted from hydrophilic to hydrophobic. Thus, the pinning effect of the raw material solution on the inner side surface of the defining layer body is reduced and the thickness uniformity of the pixel layer is improved.

Abstract: 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.
