Patent ID: 10115921

Abstract:
A quantum dot light emitting element includes a substrate, a cathode arranged on the substrate for supplying electrons, an electron injection/electron transport layer, a quantum dot light emitting layer, a hole injection/hole transport layer, and an anode for supplying holes. The cathode and the anode are arranged on the same side of the substrate. The electron injection/electron transport layer, the quantum dot light emitting layer, and the hole injection/hole transport layer are inserted between the cathode and the anode. One side of the electron injection/electron transport layer is connected to the cathode. The electron injection/electron transport layer and hole injection/hole transport layer are used for transmitting the electrons and the holes to the quantum dot light emitting layer, respectively. The electrons and the holes recombine in the quantum dot light emitting layer for emitting light. The electron injection/electron transport layer comprises a water-alcohol soluble conjugated polymer (WACPs).
