Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a display panel, comprising a pixel definition layer, a cathode and a filling structure; the cathode is covered on the pixel definition layer; a plurality of grooves are formed on the pixel definition layer, and the filling structure is formed of an inorganic material; the filling structure is located on the groove, and is configured to be in contact with the cathode. The pixel definition layer is provided with grooves and filled with a filling structure formed of inorganic materials. On the one hand, when the display panel is impacted or bent, the grooves and the filling structure can effectively disperse the stress; on the other hand, the filling structure is formed of inorganic materials. The pixel definition layer and the cathode have better binding force, and the adhesion of the cathode is improved compared with the conventional design where the cathode relies on the van der Waals force between it and the pixel definition layer. In this way, the cathode is effectively prevented from being broken or separated from the organic light-emitting layer, and the reliability of the OLED display panel's bending resistance and drop impact strength is effectively improved. Also provided are a manufacturing method of the 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...
