Abstract

The present application discloses a method for preparing quantum dots light-emitting diode, including the following step: providing a base plate, placing the base plate into an inert atmosphere containing active gas, and printing quantum dots ink on a surface of the base plate to prepare a quantum dots light-emitting layer. The method for preparing the quantum dots light-emitting diode provided in the present application changes the film-forming atmosphere of inkjet printing, and prepares the quantum dots light-emitting layer in the inert atmosphere containing active gas, which can improve the device efficiency of the quantum dots light-emitting diode while ensuring the printability of quantum dots ink.
