Problems solved by technology

In the process of use, it is found that polyimide as a substrate has insufficient hardness and the overall thickness of the device is too thick.
In addition, in the liquid crystal display module, two polarizers are attached to both sides of the substrate, and the cover plate with polarizing function is made by bonding the upper polarizer with optical glue. This design will not only cause the overall thickness to be thicker , and due to the existence of a layer of flexible optical adhesive layer, it will cause a straight drop in the hardness of the cover

Abstract

The invention discloses a flexible display screen cover plate and relates to the field of optical film technology. The flexible display screen cover plate comprises a transparent aromatic polyamide substrate; a polysilazane layer disposed on one side surface of the transparent aromatic polyamide substrate; a polarizing layer disposed on the aromatic polyamide substrate and on the other side, relative to the polysilazane layer, the aromatic polyamide substrate; and a hardened layer arranged on the polarizing layer and on the other side, relative to the transparent aromatic polyamide substrate,of the polarizing layer. According to the invention, the polarizing layer is directly prepared on the transparent aromatic polyamide substrate, so that the overall thickness of the flexible display screen cover plate is reduced, and meanwhile, the overall hardness of the flexible display screen cover plate is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of optical film display, in particular to a flexible display screen cover. Background technique [0002] The flexible display cover material is mostly composed of a rigid glass substrate or a resin substrate and a functional layer. Among them, the glass display cover cannot be bent, which does not conform to the development trend of foldable display devices. Compared with glass, polyimide material with high surface hardness and high toughness has become the preferred material for flexible display cover, but it needs surface coating. layer to increase hardness. During use, it was found that polyimide as a substrate has insufficient hardness and the overall thickness of the device is too thick. In addition, in the liquid crystal display module, two polarizers are attached to both sides of the substrate, and the cover plate with polarizing function is made by bonding the upper polarizer with optical glue. Thi...
