A kind of flexible display substrate and flexible display device

Abstract

The invention describes a flexible display substrate and a flexible display device. Wherein, the flexible display substrate has a display area and an adjacent peripheral area, the display area includes a plurality of pixel units, the flexible display substrate includes: a base substrate and at least one conductive trace arranged on the base substrate, the conductive trace includes at least Two first conductive parts and at least one second conductive part, two adjacent first conductive parts are electrically connected through the second conductive part; wherein, the Young's modulus of the first conductive part is greater than the Young's modulus of the second conductive part modulus, and the resistivity of the first conductive portion is smaller than the resistivity of the second conductive portion. In the flexible display substrate provided by the present invention, the conductive traces are not easily broken, thereby improving the bending resistance of the flexible display substrate, increasing the deformation amount that the flexible display substrate can withstand, and prolonging the life of the flexible display substrate.

AI Technical Summary

Problems solved by technology

During the use of the flexible display device, bending deformation occurs under the action of force F1. Among them, the deformation of the wire 02 at area A is relatively large, and the stress is relatively concentrated. When the secondary deformation occurs, the wire 02 is prone to breakage at the area A, resulting in an open circuit, thereby affecting the normal operation of the flexible display device
