Beschreibung
Zusammenfassung:	The invention provides quantum dot powder, a preparation method of the quantum dot powder, an LED packaging device and a preparation method of the LED packaging device. The preparation method of the quantum dot powder comprises the following steps: dispersing quantum dots in a solvent to obtain a quantum dot dispersion liquid; mixing the quantum dot dispersion liquid with synthetic resin particles to obtain a mixed material; sequentially granulating and crushing the mixed material to obtain the quantum dot powder. The quantum dot powder is obtained by mixing the quantum dot dispersion liquid with the synthetic resin particles and then sequentially performing granulation and crushing, the quantum dot powder comprises the quantum dots and the synthetic resin coating the surfaces of the quantum dots, and the synthetic resin coating the surfaces of the quantum dots can improve the water and oxygen barrier property of the quantum dots, so that the water and oxygen barrier property of the quantum dots is improved.
