Abstract

The application discloses a quantum dot ink, a quantum dot color film and a preparation method thereof. The quantum dot ink is calculated by weight fraction, including: quantum dots, 0.01wt% to 50wt%; additives, 0.1wt% to 20wt%; dispersion medium, 30wt% to 99.89wt%; wherein, quantum dots and additives are dispersed in the dispersion medium , the additive is a silylating agent. In this application, by adding an additive silylating agent to the quantum dot ink, it can generate SiO in situ in the quantum dot color film formed by printing. 2 Light-expanding particles, thereby obtaining a quantum dot color film with high brightness.

Description

technical field [0001] The application belongs to the field of nanomaterials, and in particular relates to a quantum dot ink, a preparation method of a quantum dot color film and a quantum dot color film. Background technique [0002] Quantum dot color film display has excellent characteristics such as ultra-high color gamut, low energy consumption, ultra-thin, and flexibility, and is the direction of the new generation of display technology. Inkjet printing can realize the selective deposition and precise patterning control of quantum dot display materials on the pixel substrate, and improve the utilization rate of raw materials. It is the most ideal process for preparing quantum dot color film displays. As the most basic part of full-color printing quantum dot color film devices, quantum dot ink directly affects the final display effect of quantum dot color film. [0003] In the prior art, light-diffusing particles are added to the quantum dot ink to improve the brightnes...
