Abstract

The invention discloses a flexible display panel and a preparation method thereof, and a flexible display device. The display panel includes a flexible substrate, a pixel definition layer which is arranged on the flexible substrate and is provided with a plurality of openings internally provided with light emitting structure layers, and a film packaging layer, wherein the film packaging layer comprises a first inorganic packaging layer and a first organic packaging layer which are arranged in a stacked manner, the first inorganic packaging layer is located above the light emitting structure layers in the openings of the pixel definition layer, and the first organic packaging layer covers the pixel definition layer and the first inorganic packaging layer and is in direct contact with an upper surface of the pixel definition layer. The display panel is advantaged in that the stress between an organic electroluminescent device layer and the film packaging layer can be improved, so a problem that the film layers are easy to separate when the flexible display panel is bent is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display panel, a manufacturing method thereof, and a flexible display device. Background technique [0002] At present, flexible display panels based on organic electroluminescent devices (OLEDs) generally use thin-film encapsulation layers of inorganic encapsulation layer-organic encapsulation layer-inorganic encapsulation layer, which is prone to separation between film layers when bending, resulting in encapsulation failure and affecting Lifespan of flexible display panels. Contents of the invention [0003] The present application provides a flexible display panel, a preparation method thereof, and a flexible display device, so as to solve the problem of separation between film layers when the flexible display panel is bent, improve the packaging effect, and further increase the service life of the display panel. [0004] In order to solve the above t...
