Abstract:
1. An organic light-emitting diode, comprising: a light-transmitting substrate, an anode arranged on the light-transmitting substrate, a hole transporting layer arranged on the anode, a light emission layer arranged on the hole transporting layer, an electron transporting layer arranged on the light emission layer, and a cathode arranged on the electron transporting layer, the light emission layer comprising a color light emission layer and an ultraviolet light emission layer spaced from the color light emission layer; wherein a hole blocking layer comprises a layer of 1,3,5-(benzenetriyl)tris(1-phenyl-1H-benzimidazole) or 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline; wherein the color light emission layer comprises a plurality of color pixel units regularly distributed thereon, each of the color pixel units comprising three sub-pixel points of red, green, and blue colors, the three sub-pixel points of red, green, and blue colors being driven by a Thin Film Transistor (TFT) circuit; and wherein the ultraviolet light emission layer comprises a plurality of ultraviolet pixel units regularly distributed thereon, each of the ultraviolet pixel units comprising three identical ultraviolet sub-pixel points.
