Problems solved by technology

[0004] Since the frame sealant has a large molecular gap after curing, external water and oxygen can easily penetrate the frame sealant into the interior of the organic electroluminescent display panel, depleting the organic electroluminescent structure and reducing the service life of the organic electroluminescent display panel. Therefore, how to improve the sealing performance of organic electroluminescent display devices is a technical problem that those skilled in the art need to solve urgently.

Abstract

The invention discloses an organic electroluminescent display panel and a manufacturing method thereof, and a display apparatus. According to the organic electroluminescence display panel, a first groove for accommodating an organic electroluminescent structure is formed in a display area of a packaging cover plate; and at least one second groove encircling the first groove is formed in a non-display area of the packaging cover plate, wherein the boundary of the second groove is closed. A metal layer enables a protruding part of the packaging cover plate to be bonded with a substrate. Because the protruding part of the packaging cover plate and the metal layer located between the protruding part and the substrate have high molecular densities, a high-efficiency water and oxygen blocking effect can be realized. Moreover, frame sealing glue is accommodated by the second groove and the substrate and the packaging cover plate can be bonded well based on cooperation of the frame sealing glue. Therefore, the packaging cover plate and the substrate can be bonded well based on the metal layer and the frame sealing glue. And under the circumstances the bonding between the packaging cover plate and the substrate is guaranteed, the sealing performance of the organic electroluminescent display panel can be effectively improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic electroluminescence display panel, a manufacturing method thereof and a display device. Background technique [0002] Among the existing display devices, organic electroluminescent display devices (OLED, Organic Light Emitting Diode) rely on all-solid-state, active light emission, fast response speed, high brightness, low power consumption, simple preparation process, low cost, and high luminous efficiency. As well as the advantages of being easy to form a flexible structure, it has become a more important display device at present. [0003] In existing organic electroluminescent display devices, such as figure 1 As shown, it includes: a base substrate 100, an organic electroluminescent structure 101 located on the base substrate 100, and a package cover 102; the package cover 102 and the base substrate 100 are packaged with a sealant 103, and formed after pa...
