Embodiment 1

[0038] Referring to FIG. 2(a), it is a schematic structural diagram of a flexible display panel provided by the embodiment of the present application. The flexible display panel mainly includes:

[0039] A substrate 21, a display film layer 22 located on one side of the substrate 21, an encapsulation film layer 23 located above the display film layer 22, a surface of the encapsulation film layer 23 away from the display film layer 22 is provided with a plurality of concave-convex structures T, the concavo-convex structure The structure T is used to relieve the stress in the bending direction (the direction indicated by the arrow in the figure) when the flexible display panel is bent.

[0040] It should be noted that, in this application, the bending direction is different at each position of the flexible display panel, and may extend along a tangential direction of the curved surface.

[0041] In fact, considering that during the stretching process, as the external force incre...

Embodiment 2

[0054] An embodiment of the present application further provides a display device, including the flexible display panel described in any one of the above embodiments. The display device can be any product or component with a display function such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and a smart wearable device. The other essential components of the display device should be understood by those of ordinary skill in the art, and will not be repeated here, nor should they be used as limitations on the present application.

Embodiment 3

[0056] At the same time, the present application also provides a method for manufacturing the flexible display panel described in the first embodiment above, refer to Figure 6 As shown, the preparation method mainly includes the following steps:

[0057] Step 31: forming a display film layer on one side (first surface) of the substrate.

[0058] In fact, before forming the display film layer, it also includes the process of forming a TFT array on one side of the substrate, as well as other organic or inorganic film layers, such as buffer layers and insulating layers.

[0059] Step 32: Form an encapsulation film layer above the display film layer, and form a plurality of concave-convex structures on a surface of the encapsulation film layer away from the display film layer. The concave-convex structures are used to relieve the stress in the bending direction when the flexible display panel is bent.

[0060] Specifically, in step 33, dry etching may be used to form multiple co...

Abstract

The invention relates to the technical field of display, in particular to a flexible display panel, a manufacturing method thereof and a display device in order to solve the problem of damage caused by repeated bending to outer encapsulating film layers in the prior art. According to the flexible display panel, a plurality of concave-convex structures are arranged on the surface, away from a display film layer, of the interior of an encapsulation film layer and used for relieving stress in a bending direction when the flexible display panel is bent, so that the bending performance of the encapsulation film layer is enhanced, tear damage of the surface of the encapsulation film layer is reduced, and the bending performance of the flexible display panel is improved. At the same time, the concave-convex structures can also be adopted for achieving adhesion of the adjacent film layers, and misalignment between the film layers due to bending is avoided.

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 display device. Background technique [0002] With the rapid development of display technology, flexible display technology has attracted more and more attention due to its thinness and bending resistance. [0003] Considering that during the bending process of flexible display products, the bending radii of different layers are different, and the lengths that need to be stretched are also different; after forming a flexible display module, as the number of bending increases, it is easy to be damaged after being stretched repeatedly , especially for the outer encapsulating film layer in the flexible display module, it is easy to be torn by repeated stretching, thereby seriously affecting the life of the flexible display panel.
