Embodiment Construction

[0035] 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.

[0036] 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 present invention relates to a display panel and its forming method, and a display device. The display panel comprises: an array substrate; a pixel definition layer formed on the array substrate, and the pixel definition layer defines a plurality of pixel definition openings; a light emitting layer formed on the pixel definition layer. In the opening; the cathode layer, covering the pixel definition layer and the light emitting layer; the display panel also includes a recess formed on the side of the pixel definition layer away from the array substrate, between the cathode layer covering the recess and the cathode layer covering each light emitting layer The electrical connection forms a cathode loop. For the above display panel, when an external force acts on the pixel definition layer, the surface of the pixel definition layer far away from the array substrate without the recessed portion is first subjected to the external force, and since the cathode layer covering the recessed portion can be connected with the cathode layer covering each light-emitting layer Layers form a complete cathode circuit, so when part of the cathode layer is damaged, the cathode circuit is still conducting, and the display panel can still display normally.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a display panel, a forming method thereof, and a display device. Background technique [0002] In recent years, with the development of society and the advancement of science and technology, the technological development of smart terminal equipment and wearable equipment is changing rapidly, and the requirements for flat panel display are gradually increasing, and the demand is becoming more and more diverse. OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device has lower power consumption compared with liquid crystal display, and at the same time has higher brightness and response speed, and can be bent and has good flexibility, so it is more and more used. It is more widely used in smart terminal products such as mobile phones, tablet computers and even TVs, and has become the mainstream display in the display field. [0003] However, due to ma...
