Embodiment Construction

[0022] As mentioned in the background art, there is a technical problem in the prior art that when the protective film is removed, the thin-film encapsulation layer is also peeled off, causing water and oxygen to intrude into the light-emitting layer of the display. The reason why such a problem arises is as follows. After the film encapsulation is completed, before the polarizer is attached, a protective film will be pasted on the outside of the film encapsulation layer to protect it, and the protective film will be removed when it is necessary to attach the polarizer. Due to the characteristics of the thin film encapsulation material and the protective film material itself, the adhesive force between the thin film encapsulation layer and the organic light-emitting layer is smaller than the adhesive force between the protective layer and the thin film encapsulation layer. When the protective film is removed, the thin-film encapsulation layer is also easily peeled off, causing...

Abstract

The invention provides a display panel. The display panel comprises a functional device layer, a thin film packaging layer which is positioned on one side of the functional device layer, a protectivefilm which is positioned on one side, far away from the functional device layer, of the thin film packaging layer, and a viscosity reduction layer which is positioned between the thin film packaging layer and the protective film, covers the edge of the thin film packaging layer and is used for reducing the viscosity between the edge of the thin film packaging layer and the protective film. According to the display panel provided by the embodiment of the invention, the viscosity reduction layer is arranged at the edge of the thin film packaging layer, so that the viscosity between the edge of the thin film packaging layer and the protective film is reduced. The viscosity between the edge of the thin film packaging layer and the protective film is reduced, so that the edge of the thin film packaging layer with the weakest adhesive force is not easy to peel off from the functional device layer, and the thin film packaging layer is not easy to peel off when the protective film is removed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] During the preparation of the display panel, the organic light-emitting layer is encapsulated by Thin Flim Encapsulation (TFE) to prevent the intrusion of water and oxygen. After the thin film encapsulation is completed, a protective film will be attached to the outside of the thin film encapsulation layer to protect it, and the protective film will be removed when the next process is performed. When the protective film is removed, the thin-film encapsulation layer is also easily peeled off, causing water and oxygen to intrude into the light-emitting layer of the display, and black spots appear on the corners of the display panel without display failure. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a display panel and a display device to solve the...
