Quantum dot inorganic packaging color conversion sheet and manufacturing method

The invention discloses a quantum dot inorganic packaging color conversion sheet and a preparation method thereof. The quantum dot inorganic packaging color conversion sheet comprises an inorganic glass substrate and a silicon substrate, the light-out surface of the silicon substrate is in anodic bonding with the inorganic glass substrate, a plurality of pixel grooves are etched in the light-in surface of the silicon substrate, and the pixel grooves are filled with quantum dot color conversion materials. The inorganic glass substrate is adopted to package the quantum dot color conversion material, contact between the quantum dot color conversion material and outside air can be effectively isolated, the problem that quantum dot particles in the quantum dot color conversion material fade or even are inactivated due to water vapor and oxygen in the air is solved, and the quantum dot color conversion material is more stable in color conversion. Therefore, the service life of the quantum dot color conversion mater
