Embodiment Construction

[0024] As mentioned in the background technology, the flexible display panel in the prior art often has the problem of broken wires in the non-display area. The inventors found that the root cause of this problem is that the flexible screen itself has the characteristics of thinness and softness. , the general flexible screen body is only about 20um in thickness, and it is easy to curl, making it extremely difficult to realize the overall bending of the flexible screen body. In the actual bending process, the bending area of ​​the flexible screen body is prone to uneven bending, such as only point bending or partial bending, such as warping at both ends. Moreover, it is easy to form sharp creases in the bending area after bending, which will cause creases on the screen body and break the wiring in the non-display area, which will lead to poor contact of the circuit in the display panel, affecting the bending success rate of the display panel and product quality. rate while aff...

Abstract

The present invention provides a display panel and its device. The display panel includes a display area and a non-display area. The non-display area includes a bending area and a pre-bending area. The bending area is located close to the non-display area. One side of the display area, the pre-bending area is adjacent to the bending area, and is located on the side of the non-display area away from the display area, the surface of the pre-bending area is provided with anti- A bending layer, wherein the stiffness of the anti-bending layer is greater than the stiffness of the pre-bending region. The technical scheme of the present invention improves the stiffness of the pre-bending area by providing an anti-bending layer on the surface of the pre-bending area, and ensures the synchronous bending of the non-display area when it is reversely bent, thereby avoiding the non-display The disconnection of the non-display area caused by the reverse bending of the area improves the bending effect and product yield, the operation is simple, and the difficulty of process realization is low.

Description

technical field [0001] The invention relates to the technical field of screen display, in particular to a display panel and a display device. Background technique [0002] With the advancement of display technology, the screens of electronic display products are increasingly developing towards narrow bezels or even bezel-less. Bending of flexible display panels is an important technical means to reduce the lower bezel of display devices. [0003] However, in the flexible display panel made by the bending method in the prior art, the wiring of the non-display area (that is, non-AA area, AA area, active display area, and active area) often breaks, resulting in the failure of the display area. Control failure. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is to provide a display panel and a display device, so as to solve the problem in the prior art that the wires are easily broken when the non-display area is bent....
