Abstract

The invention provides a coordination method of quantum dots, the quantum dots and a display device. The coordination method of the quantum dots includes the steps: providing quantum dots and a polymer, wherein a first ligand is arranged on the surface of the quantum dots, and the polymer is provided with coordination groups; and dissolving the quantum dots and the polymer in a solvent so as to achieve re-coordination of the coordination groups of the polymer with the quantum dots and form a second ligand on the surface of the quantum dots, and achieving separation of the first ligand from thesurface of the quantum dots so as to obtain the re-coordinated quantum dots. According to the technical scheme, the agglomeration rate of the quantum dots is reduced through re-coordination of the quantum dots with the polymer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a coordination method of quantum dots, quantum dots and a display device. Background technique [0002] With the popularity of smart mobile terminals, display panel technology has been widely used, and its development is becoming more and more rapid. [0003] Among them, QLED (Quantum Dot Light-emitting Diode, Quantum Dot Light-emitting Diode) adopts a self-luminous technology that does not require a backlight source. Compared with OLED (Organic Light-emitting Diode, organic light-emitting diode), QLED not only has many advantages such as low energy consumption, wide viewing angle, rich colors and easy flexible display, but also has a narrower luminous peak and higher color saturation. . Therefore, QLED has received great attention from academia and industry. [0004] However, QD (Quantum Dot, Quantum Dot) in QLED has the problem of agglomeration, which leads to red shift of ...
