Abstract

The invention relates to a display panel, comprising a pixel definition layer, a cathode and a compensation electrode. The pixel definition layer defines a plurality of pixel definition openings and aspacing area between the pixel definition openings. A cathode is overlaid on the pixel definition layer. The pixel definition layer is configured to cover the compensation electrode and has a contacthole communicating with an upper surface thereof so that the cathode contacts the compensation electrode through the contact hole. As that display panel is subject to drop impact or multiple bending,The thin film encapsulation layer is bent downward along the direction of the applied force, and the impact force is transmitted to the cathode layer. The compensation electrode and the cathode layeroverlap each other through the contact hole to form a three-dimensional three-dimensional network structure, which can support the cathode layer and disperse the impact stress, thereby preventing thecathode from breaking or being separated from the organic light-emitting unit. Thus, the bending strength and the impact strength against drop of the display panel are improved. Also provided are a method for manufacturing a display panel and a display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of technologies such as big data, cloud computing, and mobile Internet, human beings have entered the era of intelligence, including smart mobile communication terminals, wearable devices, and smart home devices, which have become an indispensable part of people's work and life. As an important window for human-computer interaction in the era of intelligence, display panels are also undergoing major changes. Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has the advantages of thin thickness, self-luminous performance, low power consumption, and good flexibility. Flat panel display device. [0003] In order to pursue a better visual experience and tactile experience, the requirements for the effective display area and...
