Problems solved by technology

[0003] Electrostatic discharge occurs for a very short time, and a large amount of charge transfers in a short period of time will generate extremely high current, break down semiconductor devices, or generate enough heat to melt semiconductor devices. This hazard is usually not noticed. Cause some components to be degraded or scrapped, resulting in large economic losses
Therefore, electrostatic discharge will bring fatal hazards to electronic products, which not only reduces the reliability of production, but also increases maintenance costs

Embodiment Construction

[0078] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The application discloses an organic electroluminescent display panel and a display device, which relate to the field of display technology, wherein the organic electroluminescent display panel has a display area and a non-display area surrounding the display area, including: a base substrate; The packaging metal layer on the top, the packaging metal layer is located in the non-display area and arranged around the display area; the insulating layer and the polysilicon layer are arranged between the base substrate and the packaging metal layer, and the insulating layer is arranged on the side of the polysilicon layer away from the base substrate On the surface, the polysilicon layer includes a plurality of discharge tips. In such a solution, when the organic electroluminescent display panel in the present application is subjected to static electricity, the discharge tip on the polysilicon layer can release the external static electricity, preventing external static electricity from causing damage to the display panel and the display device. In addition, due to the polysilicon layer It takes up less space, so this solution is also conducive to the realization of narrow bezel design.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to an organic electroluminescent display panel and a display device. Background technique [0002] During the production process of the display panel, due to some external factors, such as continuous process operation and handling or environmental changes, etc., electrostatic charges usually accumulate in the panel. Since glass itself is an insulating substance, unless there is a suitable discharge channel, the charge will remain on the surface of the substrate. When the electrostatic charge accumulates to a certain amount, a discharge will occur. [0003] Electrostatic discharge occurs for a very short time, and a large amount of charge transfers in a short period of time will generate extremely high current, break down semiconductor devices, or generate enough heat to melt semiconductor devices. This hazard is usually not noticed. It will cause some components to be ...
