Abstract

The invention discloses a composition for preparing a polarizing film, a preparation method of the polarizing film, the polarizing film and a display module. The composition comprises a polymerizable dichroic dye, a liquid crystal polymerizable monomer and a cross-linking agent. According to the composition for preparing the polarizing film, the liquid crystal polymerizable monomer and the cross-linking agent are added into the polymerizable dichroic dye, so that the flexibility of the prepared polarizing film is improved, and the bending performance of the polarizing film can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a composition for preparing a polarizing film, a method for preparing a polarizing film, a polarizing film, and a display module. Background technique [0002] Flexible display technology is a development boom in the display field today, and the future display technology will develop in the direction of flexible foldable, flexible rollable, flexible stretchable and other arbitrary forms of display. Among them, flexible materials are the core carrier of flexible display technology. At present, the polarizer is the key structure restricting the flexible display technology. [0003] Dye polarizers are polarizers that rely on the anisotropic absorption properties of dichroic dyes, but the existing dye polarizers have high hardness, resulting in poor bending performance of the polarizers, which is not conducive to the development of flexible display technology.
