Abstract

The embodiment of the invention relates to the field of display technology, and discloses a flexible display panel and a flexible display device adopting the flexible display panel. In the invention,the flexible display panel comprises a flexible substrate and an anode film layer of multiple pixels arranged on the flexible substrate, wherein the anode film layer forms a stress decomposition structure for reducing the stress of at least part of the local film layer of which the area is larger than a preset value, thereby reducing the stress accumulation of the anode film layer. In the embodiment of the invention, the stress concentration in a larger area of the sub-area of the anode film layer can be reduced by reducing the stress in a small area larger than a certain area on the anode film layer, thereby effectively preventing the breakage of the anode film layer, and improving the pixel brightness and the reliability of the product.

Description

technical field [0001] Embodiments of the present invention relate to the field of flexible display technologies, and in particular to a flexible display panel and a flexible display device using the flexible display panel. Background technique [0002] With the development of display technology, display panels are widely used in portable electronic products such as mobile phones and handheld computers, especially flexible display screens. Favored by users, it will become the development trend of various smart display screens in the future. However, the existing flexible display panels still have a large reliability risk when they are bent. [0003] The inventors have found that at least the following problems exist in the prior art: in current flexible display technologies such as Organic Light-Emitting Diode (OLED), the area of ​​the anode layer is relatively large, and the anode is prone to breakage when it is bent, causing some There is no display in the pixel display ...
