Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] figure 1 It is a structural schematic diagram of a retaining wall in the prior art. As mentioned in the background art, the display panel using the structure and material of the retaining wall in the prior art has a poor encapsulation effect. The reason for this problem is that the existing retaining wall is usually as follows figure 1 In the stacked structure of multi-layer organic layers shown, there may be poor stacking between two adjacent organic layers and a small gap in the middle; into the case of...

Abstract

An embodiment of the invention discloses a display panel. The display panel comprises a substrate, at least one retaining wall, a light-emitting device and a packaging layer, wherein the substrate comprises a display area and a non-display area; the retaining wall is arranged on one side of the substrate, is positioned in the non-display area, and is arranged around the display area; the light-emitting device and the retaining wall are arranged on the same side of the substrate and are located in the display area; the packaging layer covers the retaining wall and the light-emitting device, wherein each retaining wall comprises at least two layers of blocking structures, wherein the blocking structure farthest from the packaging layer is coated by at least one of the other blocking structures, and then the invasion path of water oxygen between blocking structure film layers of the retaining wall is further prolonged, so that water vapor and oxygen are difficult to enter the display areaof the display panel between the barrier structure film layers of the retaining wall, the packaging effect of the display panel is improved, water vapor and oxygen are difficult to corrode the light-emitting device, and the service life of the display panel is prolonged.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel. Background technique [0002] With the development of display panel packaging technology, the application of flexible packaging is becoming more and more extensive. [0003] Thin-film packaging is a packaging method of flexible packaging. Usually, the thin-film packaging structure includes inorganic, organic, and inorganic three-layer structures. Because the organic layer has fluidity, a retaining wall structure is required to intercept it. However, the display panel adopting the retaining wall structure and the thin film encapsulation layer in the prior art has a poor encapsulation effect, which affects the life of the display panel. Contents of the invention [0004] The invention provides a display panel to improve the packaging effect of the display panel and prolong the service life of the display panel. [0005] An embodime...
