Display panel, and preparation method thereof and display device

Abstract

The invention discloses a display panel, and a preparation method thereof and a display device, which are used for improving the packaging yield. The embodiment of the invention provides a display panel. The display panel comprises: a substrate; and a display panel which is provided with a display area and a peripheral area located outside the display area. The peripheral area comprises a retaining wall and a magnetic structure which are arranged on the substrate and surround the display area; the magnetic structure is located between the retaining wall and the display area; the display area comprises an electroluminescent device arranged on the substrate and a packaging layer for sealing the electroluminescent device; the encapsulation layer includes: an organic encapsulation layer covering the magnetic structure and extending to the retaining wall; the organic encapsulation layer comprises a magnetic part; and the magnetic structure is used for generating magnetic force to the magnetic part in the organic packaging layer and preventing the organic packaging layer from crossing the retaining wall.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light emitting diode display devices have self-luminous properties, and because organic light emitting diode display devices have characteristics such as low power consumption, high brightness and fast response speed, organic light emitting diode display devices have received more and more attention. In the display panel of the organic light emitting diode display device, it is necessary to use a protective layer to protect the organic light emitting element and to block the external water and oxygen. In the related art, the protective layer generally includes: a first inorganic film, an organic film layer disposed on the first inorganic film layer, and a second inorganic film layer disposed on the organic film layer. Wherein, the first inorganic film layer and...

Problems solved by technology

However, the liquid organic material is easy to overflow over the retaining wall, and the liquid organic material has the characteristic of absorbing water and oxygen. When the liquid organic material overflows, the second inorganic layer cannot completely cover the organic layer, resulting in the organic layer being partially exposed to the air. In the middle, it provides conditions for the intrusion of water and oxygen in the air, which leads to the failure of the package, affects the protective effect of the protective layer on the organic light-emitting elements, and shortens the service life of the organic light-emitting diode display device.
