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 technical field of optical films. The flexible display screen cover plate in the invention comprises a transparent aromatic polyamide substrate, an anti-fingerprint hardness layer, a polarizing layer, and a hardened layer; the anti-fingerprint hardness layer is arranged on one side surface of the transparent aromaticpolyamide substrate; the polarizing layer is arranged on the other side surface of the aromatic polyamide substrate relative to the anti-fingerprint hardness layer; and the hardened layer is arrangedon the other side surface of the polarizing layer relative to the transparent aromatic polyamide substrate. According to the flexible display screen cover plate in the invention, the polarizing layeris directly prepared on the transparent aromatic polyamide substrate, so that the overall thickness of the flexible display screen cover plate is reduced, and 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...
