Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] Flexible display panels are generally encapsulated with a thin film encapsulation structure to block water and oxygen and protect display elements. The thin-film packaging structure is usually composed of multi-layer films. During the bending process of the flexible display panel, separation between the various film layers is easy to occur, resulting in package failure and reducing the service life of the flexible display panel.

The invention provides a flexible display panel and a manufacturing method thereof, and a display device. The flexible display panel comprises a substrate, a luminescent device layer and a film packaging structure, wherein the luminescent device layer is arranged on the substrate; the film packaging structure is arranged on the luminescent device layer, the film packaging structure includes a first inorganic layer, a first transition layer, and a second inorganic layer which are stacked; and the first transition layer includes at least one first region and at least one second region, the at least one first region and the at least one second region are alternately arranged on a plane where the first transition layer is located, a material corresponding to the at least one first region includes an inorganic material, and the material corresponding to the at least one second region includes an organic material. In the technical scheme of the invention, under a condition that a bending effect of the flexible display panel can be ensured, a binding force between the first inorganic layer and the second inorganic layer is increased to improve stability of the packaging structure.
Description
technical field [0001] The invention relates to the display field, in particular to a flexible display panel, a preparation method thereof, and a display device. Background technique [0002] Flexible display panels are widely used in life and work, such as mobile phones, tablets, and wearable devices, due to their characteristics of being bendable, foldable, thin, light, and small in size. The packaging structure of the flexible display panel has a protective effect on the display elements of the flexible display panel, but the existing packaging structure is prone to film layer separation during the bending process of the flexible display panel, which leads to the failure of the packaging of the flexible display panel. Contents of the invention [0003] In view of this, embodiments of the present invention provide a flexible display panel, a manufacturing method thereof, and a display device, which can increase the bonding force between the first inorganic layer and the ...
