Claim 0:
1. A QLED manufacturing method, comprising the following steps of:
providing a substrate provided with an electron transport layer, wherein the substrate provided with the electron transport layer comprises: an anode substrate, a quantum dot light emitting layer provided on the anode substrate, and the electron transport layer provided on a side of the quantum dot light emitting layer facing way from the anode substrate; wherein the substrate provided with the electron transport layer further comprises a cathode substrate, and the electron transport layer is provided on the cathode substrate;
depositing a solution on a surface of the electron transport layer, standing until the electron transport layer is infiltrated by the solution, and then performing a drying operation, wherein the solution comprises a main solvent and a solute dissolved in the main solvent, a polarity of the solute is greater than a polarity of the main solvent, and the solution is not able to dissolve an electron transport material in the electron transport layer.
