preparation example Construction

[0046] An embodiment of the present invention provides a method for preparing a composition for a flat protective layer, comprising:

[0047] A photocurable unsaturated resin oligomer with a mass fraction of 30% to 60%, a photopolymerizable monomer with a mass fraction of 30% to 60%, a photosensitizer with a mass fraction of 1% to 10%, and a mass fraction of Additives with a fraction of 0% to 5% are mixed and dispersed to obtain a composition for microcapsule cores;

[0048] adding the composition for the microcapsule core dropwise into the solution of the microcapsule wall to form microcapsules;

[0049] The microcapsules with a mass fraction of 1% to 10% are mixed with the components of the composition for flat protective layer to form the composition for flat protective layer. The components of the composition for a flat protective layer may be other components of the composition for a flat protective layer of the present invention excluding microcapsules, or may be compon...

Abstract

The invention relates to the technical field of display, and especially relates to a composition used in a flat protective layer, a preparation method thereof, and a display device. The composition used in the flat protective layer comprises microcapsules with a mass percentage of 1-10%. The microcapsule wall comprises alkali-insoluble resin. The microcapsule core comprises, by mass, 30-60% of a light-curable unsaturated resin oligomer, 30-60% of photopolymerizable monomer, 1-10% of a photosensitizer, and 0-5% of an additive. With the technical scheme provided by the invention, reparation of a damaged part of a flat protective layer can be realized, and product yield can be greatly improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a composition for a flat protective layer, a preparation method thereof, and a display device. Background technique [0002] Among flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, etc., and occupies a dominant position in the current flat panel display market. leading position. [0003] At present, the main structure of TFT-LCD includes an array substrate and a color filter substrate (CF) that are boxed together. Among them, the color filter substrate mainly includes: a glass substrate, a black matrix (Black Matrix, BM for short), a color photoresist, and an overcoat (OC for short) layer. Generally speaking, the black matrix is ​​arranged in the form of grids, stripes or speckles between the color patterns formed by the co...
