Problems solved by technology
The organic light-emitting layer of an active matrix organic light-emitting diode (AMOLED) display device is usually made by evaporation process or inkjet printing process; layer is difficult to achieve high resolution; and the organic light-emitting layer formed by the inkjet printing process is also difficult to achieve high resolution
Therefore, the resolution of the active matrix organic light emitting diode (AMOLED) display device is relatively low, and it is difficult to compete with the liquid crystal display device (LCD)

Abstract
The invention discloses a quantum dot light-emitting structure, a manufacturing method thereof and a display device. The manufacturing method of the quantum dot light-emitting structure comprises the following steps: coating a substrate with a first quantum dot solution comprising a first quantum dot of which the surface is modified with a first ligand and a photoinduced ligand remover to form a first quantum dot light-emitting material layer; partially exposing the first quantum dot light-emitting material layer, so as to enable the first quantum dot light-emitting material layer to comprise an exposed part and an unexposed part, and configuring a photoinduced ligand remover to release the ligand remover under illumination so as to remove a first ligand in the exposed part of the first quantum dot light-emitting material layer; and developing and washing the exposed first quantum dot light-emitting material layer by using a first washing solvent to form a first quantum dot light-emitting layer. Therefore, the manufacturing method of the quantum dot light-emitting structure can ensure the light-emitting performance of the first quantum dot light-emitting layer.
Description
technical field [0001] Embodiments of the present disclosure relate to a quantum dot light-emitting structure, a manufacturing method thereof, and a display device. Background technique [0002] Due to the advantages of wide viewing angle, high refresh rate, low power consumption, and flexible display, the active matrix organic light emitting diode (AMOLED) display device is considered to be the next generation display technology to replace the liquid crystal display device (LCD). With the continuous development of the consumer market, consumers have higher and higher requirements for the resolution of display devices. The organic light-emitting layer of an active matrix organic light-emitting diode (AMOLED) display device is usually made by evaporation process or inkjet printing process; Layer is difficult to achieve high resolution; and the organic light-emitting layer formed by the inkjet printing process is also difficult to achieve high resolution. Therefore, the reso...
