Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0020] Where possible, the same or similar parts will be given the same reference numerals in the drawings.

[0021] As mentioned in the background art, in the prior art, a multilayer structure of inorganic layers and organic layers is often used in the film sealing structure to effectively prevent water vapor and oxygen from penetrating into the display. However, the inorganic layer of this structure has a certain rigidity, and its adhesion with other film layers is poor. During the bending and ...

Abstract

The invention provides a display panel and a display device, and relates to the technical field of display. The display panel includes a substrate; an organic light-emitting layer which is positionedat one side of the substrate; a film packaging layer which is located at one side, far away from the substrate, of the organic light-emitting layer, wherein the thin film packaging layer comprises atleast one inorganic layer and at least one organic layer. At least one inorganic layer and at least one organic layer are alternately arranged, wherein one inorganic layer, close to the organic light-emitting layer, of at least one inorganic layer comprises a lamination layer of at least two sub-inorganic layers, and one sub-inorganic layer, close to the organic light-emitting layer, of the at least two sub-inorganic layers is of a composite film layer structure. Therefore, the problem that the service life of the display panel fails due to the fact that the existing inorganic layer is separated from other film layers due to poor adhesive force and packaging is affected is effectively solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Electronic devices, especially organic electronic devices, are particularly sensitive to moisture and oxygen in the air, so organic devices need to be packaged to ensure the performance and service life of the device. Organic light-emitting display devices generally include a sealing structure for blocking oxygen and water vapor. In the prior art, a multilayer structure of inorganic layers and organic layers is often used in the film sealing structure to effectively prevent water vapor and oxygen from penetrating into the display. However, the inorganic layer of this structure has a certain rigidity, and its adhesion with other film layers is poor. During the bending and use of flexible displays, defects or cracks or even cracks are easily generated due to stress, and it is very easy to be damaged due ...
