Abstract

The invention provides a flexible cover plate and a flexible display screen, and the flexible cover plate comprises a composite layer which comprises first flexible glass, second flexible glass, and atransparent organic filling layer; a polymer material layer formed on the composite layer; and a hardened layer which is formed on the polymer material layer and is far away from one side of the composite layer; wherein in the bending area, the first flexible glass comprises a first base part and a plurality of first protrusions regularly arranged on the first base part, and the first protrusionsare arranged on the side close to the second flexible glass; the first flexible glass and the second flexible glass are oppositely arranged to form a gap, and the gap between the first flexible glassand the second flexible glass is filled with the transparent organic filling layer. The first flexible glass and the second flexible glass guarantee the hardness requirement of the flexible cover plate, meanwhile, in the bending area, the transparent organic filling layer improves the flexibility and bending resistance of the flexible cover plate, and the risk that the flexible cover plate cracksdue to stress concentration in the bending process of the flexible display screen is avoided.

Description

technical field [0001] The present application relates to the display field, in particular to a flexible cover and a flexible display. Background technique [0002] Flexible displays are gradually being widely used in various electronic products due to their excellent characteristics such as bendability, long life, and high resolution. [0003] The flexible display includes a flexible display panel and a flexible cover for protecting the flexible display panel. For the flexible cover, its surface is in direct contact with the external environment to protect the flexible display panel, so it needs to have sufficient hardness, but sufficient hardness usually leads to low flexibility. When the hardness requirement is met, when the existing flexible display screen is bent, a large amount of stress will be concentrated at the bending position, so that cracks appear on the flexible cover. [0004] Therefore, the existing flexible display screen has the problem of poor bending re...
