Abstract

The invention discloses thermocuring quantum dot ink and a preparation method and a use method thereof. The thermocuring quantum dot ink comprises the following components in parts by weight: 1-30 parts of quantum dots, 20-50 parts of epoxy resin, 30-75 parts of a solvent, 1-3 parts of a dispersing agent, 0.1-2 parts of an antifoaming agent, 0.5-2 parts of a leveling agent and 1-5 parts of a glassadhesion promoter. The thermocuring quantum dot photochromic conversion film ink provided by the invention can be printed on a glass substrate, is mixed with a flexible curing agent, does not blister, has a good leveling effect and uniform quantum dot dispersion, and is suitable for an intaglio pad printing process and a silk-screen printing process.

Description

technical field [0001] The invention belongs to the technical field of quantum dot inks, and in particular relates to a thermosetting quantum dot ink, a preparation method and a use method thereof. Background technique [0002] After 20 years of development, my country's major display panel manufacturers, such as BOE, Tianma, China Star, etc., have dominated the traditional LCD panel market and become leaders in the international market. In order to improve competitiveness, major international manufacturers such as Samsung Electronics have turned to the development of higher-quality quantum dot (Quantum Dot, QD) display panels, using blue OLED or μ-LED through the quantum dot light color conversion film (QD Color Change Film) ,QD-CCF), can realize wide color gamut display, and has energy-saving effect. [0003] At present, quantum dot photochromic conversion film (QD-CCF) is produced by using the same method of yellow light lithography as the production of color filters, bu...
