Abstract

The present invention provides a display panel packaging structure, a display panel and a display device. The packaging structure includes two substrates disposed opposite to each other and an edge packaging layer. The edge packaging layer includes a first packaging part and a second packaging part that are connected to each other. The first packaging The part is arranged in the non-display area of ​​the first substrate and is in contact with the second substrate; the second encapsulation part bypasses the side of the second substrate and covers the side of the second substrate away from the first substrate. The encapsulation structure prolongs the invasion path of moisture and oxygen, and improves the effect of blocking the invasion of water and oxygen. At the same time, there is no need to increase the area of ​​the non-display area, which can be well adapted to the design of the narrow frame. The display panel adopting this structure has good encapsulation effect, long service life of the light-emitting device, stable display effect and high yield.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel packaging structure, and a display panel and a display device including the packaging structure. Background technique [0002] During the production process of the display panel, the light-emitting device needs to be packaged and protected to prevent water vapor and oxygen from entering the interior of the light-emitting device, resulting in abnormal display and reduced lifespan, which affects the performance of the display. [0003] In the current packaging method, the non-display area at the edge is usually sealed with an encapsulant. In order to improve the encapsulation effect, the method of expanding the coverage of the encapsulant is often used to extend the path of water vapor intrusion, but it increases the area of ​​the non-display area. This goes against the current trend of narrow bezels of display devices. [0004] It should be noted tha...
