Problems solved by technology

Therefore, when the flexible display panel is bent, due to the poor toughness of the metal material, the thin film transistor and the metal wiring are deformed and broken after being subjected to bending stress.
In particular, the deformation and breakage of the source / drain and the gate of the thin film transistor will affect the electrical characteristics of the thin film transistor, making the display worse when bent

Abstract

The present invention provides a display panel, which includes: a flexible substrate, the flexible substrate includes a plurality of first regions and a plurality of second regions, and the first regions and the second regions are alternately arranged Cloth; a display device layer located on the first side of the flexible substrate, the display device layer comprising a plurality of display elements, the plurality of display elements are located in the first region and the second region, the display elements including a first electrode, a second electrode, and a functional layer located between the first electrode and the second electrode; a plurality of thin film transistors located on the first side of the flexible substrate, and the thin film transistors are located only on the In the second area, the first electrodes of the display elements located in the first area are electrically connected to the thin film transistors in the second area. When a force is applied, the first region bends first, thereby reducing the bending stress suffered by the thin film transistor located in the second region, and improving the display effect during bending.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device including the display panel. Background technique [0002] Flexible displays are a type of deformable and bendable display devices. Among them, the flexible display panel is the most important component in the flexible display. The flexible display panel is a panel in which the display device layer and the thin film transistors and signal lines controlling the display device layer are arranged on one side of the flexible substrate. [0003] In the prior art, thin film transistors and signal lines are usually made of metal materials in order to obtain good conductivity. Therefore, when the flexible display panel is bent, due to the poor toughness of the metal material, the thin film transistor and the metal wiring are deformed and broken after being subjected to bending stress. In particular, the deformation and breakage of the sour...
