摘要： A method of fabricating a perovskite light emitting device is provided. In one embodiment, the method comprises the steps of: providing a substrate; providing a first electrode disposed over the substrate; providing a bank structure disposed over the substrate, wherein the bank structure is patterned so as to define at least one sub-pixel on the substrate; providing a first transport layer ink, wherein the first transport layer ink comprises at least one solvent and at least one first charge transport material mixed in the at least one solvent; depositing the first transport layer ink into the at least one sub-pixel over the first electrode using a method of inkjet printing; vacuum drying the first transport layer ink inside a vacuum drying chamber to assemble a first transport layer over the first electrode in the at least one sub-pixel; annealing the first transport layer; providing a perovskite ink, wherein the perovskite ink comprises at least one solvent and at least one perovskite light emitting material mixed in the at least one solvent; depositing the perovskite ink into the at least one sub-pixel over the first transport layer using a method of inkjet printing; vacuum drying the perovskite ink inside a vacuum drying chamber to assemble a perovskite emissive layer over the first transport layer in the at least one sub-pixel; annealing the perovskite emissive layer; and depositing a second electrode over the perovskite emissive layer using a method of vapour deposition. Perovskite light emitting devices and displays fabricated using the provided method are also provided.
