The embodiment of the present invention relates to the field of display technology, and discloses a flexible display panel and a flexible display device. In the present invention, the flexible display panel includes: a driving circuit layer, a planarization layer stacked on the driving circuit layer, and anode patterns of a plurality of pixels arranged on the planarization layer; the flexible display panel also includes : an anode connection bar arranged on the planarization layer and located below the anode pattern of at least some pixels; the bending resistance of the anode connection bar is greater than the bending resistance of the anode pattern; the anode connection bar It is electrically connected with the driving circuit layer, and a plurality of local areas of the anode pattern are electrically connected with the anode connection strips below it. In the embodiment of the present invention, the anode pattern is electrically connected to the drive circuit through the anode connection strip, which increases the electrical connection between the local anode pattern and the drive circuit, so that the performance of each part of the anode can be effectively guaranteed when the anode is cracked, and the reliability of the product can be improved. .
Description
technical field [0001] The embodiments of the present invention relate to the field of display technology, 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 there are at least the following problems in the prior art: in current flexible display technologies such as Organic Light-Emitting Diode (OLED), the anode area of the pixel is relatively large, and the anode is prone to breakage or peeling off when it is bent. cause a decrease in display performance. ...
