Problems solved by technology

However, in the actual production process, especially when using printing equipment for inkjet printing to form the organic material layer in the packaging structure, the phenomenon of printing ink overflow often occurs, and this overflow phenomenon occurs in the special-shaped frame of the display device Especially in the area
It has been found that once this overflow of printing ink occurs, a channel formed by the overflowing printing ink will be generated in, for example, the shaped frame area, and water and / or oxygen in the outside air can easily enter along this ink channel. The interior of the display device, thereby affecting the normal display and / or display quality of the display device

Embodiment Construction

[0020] A display panel provided by an embodiment of the present invention and a display device including such a display panel will be described clearly and in detail below with reference to the accompanying drawings.

[0021] As mentioned above in the background technology section, in general, in the process of manufacturing organic light-emitting displays, it is often necessary to use packaging structures to encapsulate the light-emitting and display parts of the core, so as to prevent water and oxygen in the outside air from affecting the organic light-emitting displays. damage. Typically, such encapsulation structures have relatively low permeability to water and oxygen. As a specific implementation manner, in an organic light emitting display, a three-layer encapsulation structure is often used, which is formed by stacking an inorganic material layer, an organic material layer and an inorganic material layer. In the process of forming such a three-layer encapsulation stru...

Abstract

The present invention provides a display panel and a display device including the display panel. The display panel includes a display area at the center and a frame area surrounding the display area, and the frame area further includes a frame area with a different shape and a frame area without a different shape. The display panel further includes: a base substrate, and a first barrier structure and one or more second barrier structures located on the base substrate. The first barrier structure is arranged at least in the shaped frame region, and at least one of the one or more second barrier structures is arranged only in the shaped frame region.

Description

technical field [0001] The present invention relates to the field of display technology, and provides a display panel and a display device including the display panel. Background technique [0002] In the packaging process of display devices such as Active Matrix Organic Light Emitting DEVICE (AMOLED), a three-layer packaging structure composed of inorganic materials, organic materials and inorganic materials is usually used to package the core display part. for encapsulation. In such a three-layer encapsulation structure, the central organic material layer is usually fabricated by direct inkjet printing using a printing device. However, in the actual production process, especially when printing equipment is used for inkjet printing to form the organic material layer in the packaging structure, the phenomenon of printing ink overflow often occurs, and this overflow phenomenon occurs in the special-shaped frame of the display device especially in the region. It has been fo...
