Abstract

The invention provides a quantum dot colored film and a preparation method therefor. The preparation method comprises the steps of providing a transparent substrate, and preparing an organic thin film and a first single-color photoluminescence quantum dot thin film on the substrate in sequence, wherein the organic thin film is formed by a transparent organic matter containing a C-H bond in a deposition manner; the photo-induced quantum dots used for forming the photoluminescence quantum dot thin film adopt the quantum dots, the surfaces of which are modified by organic groups; performing HHIC (hyperthemal hydrogen induced cross-linking) processing on the photoluminescence quantum dot thin film by a mask to enable the uncovered photo-induced quantum dots, and the photo-induced quantum dots and the organic thin film to be crosslinked; washing the photoluminescence quantum dot thin film which is processed by HHIC to remove the photo-induced quantum dots which are not crosslinked to obtain a patterned photo-induced quantum dot thin film; and repeatedly performing the steps of depositing the photoluminescence quantum dot thin film, HHIC processing and washing processing, and depositing a second single-color and/or a third single-color photoluminescence quantum dot thin film to obtain the quantum dot colored film.

Description

Technical field [0001] The invention belongs to the technical field of flat panel displays, and particularly relates to a quantum dot color film and a preparation method thereof. Background technique [0002] In the contemporary information society, the importance of displays as the transmission medium of visual information is further strengthened. In order to dominate in the future, displays are moving towards lighter, thinner, lower energy consumption, lower cost and better image quality. Trend development. [0003] The color gamut of LCD TVs currently on the market is between 68-72% NTSC (National Television Standards Committee, (United States) National Television Standards Committee) standards, and the display effect is not high. Therefore, improving the color gamut of LCD TVs has become an industry research the key of. Quantum dot materials refer to inorganic semiconductor nanocrystalline grains with a particle size between 1-100nm. Because electrons and holes are quantum co...
