Abstract

The invention relates to a quantum dot optical thin film without a barrier film and a preparation method thereof. The quantum dot optical thin film comprises a body which prepared by curing a quantumdot colloid solution to form a film. The quantum dot colloid solution comprises, by weight, 0.5 part of a quantum dot solution and a resin solution, wherein the quantum dot solution has a concentration of 15 mg/L; the resin solution comprises, by weight, 10 parts of organic resin, 100 to 400 parts of a diluent and 0.1 part of an auxiliary agent; and the above components are mixed in proportion toprepare the quantum dot colloid solution which is then naturally dried in the air for film formation. According to the quantum dot optical thin film of the invention, quantum dots are wrapped by organic resin in virtue of the film forming property of the organic resin, and supporting with a substrate and protection via a barrier film are not needed; after the quantum dot optical thin film is formed after curing, the quantum dot optical thin film can be directly used and has excellent water and oxidation resistance and improved light transmittance; and the preparation method is simplified and material cost is reduced.

Description

technical field [0001] The invention relates to the technical field of quantum dot optical films, in particular to a quantum dot optical film without a barrier film and a preparation method thereof. Background technique [0002] Display technology has developed to today, from monochrome to color, from fuzzy to clear, from small to large, after countless changes, the production technology of the display is constantly improving and perfecting, so that its products can adapt to the ever-changing consumption of consumers Psychology and consumer behavior. [0003] At present, quantum dot optical films are applied in display technology. Quantum dots are semiconductor nanocrystals, which can accurately transport light when used in display technology, have an efficient display color gamut value, make the color more pure and vivid, and make the color performance more tense. [0004] Quantum dot optical film is prepared by making quantum dot colloidal solution. The preparation of q...
