Problems solved by technology

[0003] During the research and practice of the prior art, the inventors of the embodiments of the present invention found that in order to enhance the protection performance at the source and drain metal traces in the bending area, please refer to figure 1 , in the prior art, only the bending part is set in the bending area. In order to prevent the bending area from breaking during bending, UV curing (Ultraviolet, UV) glue is generally applied on the bending area, which helps to reduce the Tensile stress, but the accuracy of UV coating position is poor, the coating boundary is not well controlled, and the thickness of different areas is uneven, the viscosity is poor, and the force may fall off. At the same time, UV glue can only be used for partial protection. In the process of testing, testing, mobile phone assembly, etc., the source and drain metal wires on both sides are under the greatest force, and are easily subject to external force collisions, interference and other factors, which may cause the source and drain metal wires on both sides to break, thereby damaging the flexible display screen, resulting in Lower product yield

Abstract

The invention discloses a display panel and an electronic device. The display panel comprises a flexible display panel which comprises a display region and a bending region disposed outside the display region. The display region and the bending region are of an integrated structure, the bending area is provided with a bending part and a bending protection part, and a metal wire is arranged in thebending part. The bending protection cloth is distributed at the two sides of the bending part, and the bending part and the bending protection part are of an integrated structure. According to the embodiment of the invention, the bending protection part is additionally arranged in the bending area, the bending protection part is provided with the plurality of protection part metal wires, and themetal wires in the bending protection cloth are used for improving the local stress borne by the source and drain metal wires of the bending part during bending, so that the stress concentration coefficient of the metal wires in the bending area during bending is reduced, and accordingly the phenomenon that the source and drain metal wires in the bending area are broken is improved, the bending resistance is improved, and the production yield of products is improved.
