Embodiment Construction

[0020] 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, not all, embodiments of the present invention. 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.

[0021] Wherein, the size and shape of each structure in the drawings do not reflect their true proportions, and the purpose is only to schematically illustrate the content of the present invention.

[0022] A flexible display panel provided by an embodiment of the present invention, such as Figure 2a to Figure 2c As shown, it includes: a substrate 01, an organic electroluminescent structure 02 located on the substrate 01, and an encapsulation film layer 03 co...

Abstract

The invention discloses a flexible display panel and a display device, comprising: a substrate, an organic electroluminescent structure located on the substrate, and a packaging film layer covering the organic electroluminescent structure. The flexible display panel also includes: a first upper protective layer attached to the side of the packaging film layer away from the organic electroluminescent structure, a first lower protective layer attached to the side of the substrate away from the organic electroluminescent structure; and the first The upper protection layer exceeds the area where the substrate is located at least in the direction of the bending axis of the flexible display panel; and / or the first lower protection layer exceeds the area where the substrate is located at least in the direction of the bending axis. The portion of the first upper protective layer or the first lower protective layer that exceeds the substrate avoids the problem of stress concentration at the edge of the packaging film layer when the flexible display panel is bent, thereby alleviating the problem of crack propagation caused by the bending of the flexible display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a display device. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode, organic electroluminescence) devices are considered to be the flat panel display devices with the most development potential, and at the same time considered to be the display technology most likely to be made into flexible display devices. [0003] Existing flexible display panels such as figure 1 As shown, it generally includes: a flexible substrate 01 , an organic electroluminescent structure 02 located on the flexible substrate 01 , and an encapsulation film layer 03 covering the organic electroluminescent structure 02 . In order to reduce impurity particles in the process and ensure the quality of the encapsulation film layer 03 during preparation, the encapsulation film layer 03 is generally formed into a film on the entire surface, and then cut.
