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 present application provides a display panel and a display device, which relate to the field of display technology. A display panel, comprising: a substrate; an organic light-emitting layer on one side of the substrate; a thin-film encapsulation layer on a side of the organic light-emitting layer away from the substrate, the thin-film encapsulation layer comprising at least one inorganic layer and At least one organic layer, the at least one inorganic layer and the at least one organic layer are arranged alternately, wherein, one of the at least one inorganic layer disposed close to the organic light-emitting layer includes at least two layers A stack of sub-inorganic layers, and one of the at least two sub-inorganic layers disposed close to the organic light-emitting layer has a composite film layer structure. This effectively solves the problem that the poor adhesion between the existing inorganic layer and other film layers leads to the detachment of the film layer, which affects the packaging and causes the failure of the service life of the display panel.

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 ...
