Problems solved by technology

However, since the surface shape of SUS is fixed, when the flexible screen body is bent along the surface shape of SUS, it will be subjected to different degrees of stress, which will cause the flexible screen body to break easily or the film layer to separate; at the same time, the flexible screen body leads to the flexible circuit. One side of the board (Flexible Printed Circuit, FPC) will interfere with the SUS, which will affect the manufacturing process of the flexible display panel

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] Meanwhile, the drawings and descriptions of the embodiments are illustrative rather than restrictive. Like reference numerals refer to like elements throughout the specification. Also, for understanding and ease of description, the thickness of some layers, films, panels, regions, etc. may be exaggerated in the drawings. Also, it will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or interv...

Abstract

The invention discloses a flexible display panel and a flexible display device. The flexible display panel comprises a supporting substrate and a flexible screen body arranged on the supporting substrate, wherein the supporting substrate comprises a non-bending area and a first bending area, and the first bending area is arranged on the outer edge of the non-bending area; the first bending area comprises a supporting part, a first protection part and a second protection part, the first protection part and the second protection part are located on the two sides of the supporting part respectively, a concave area is defined by the first protection part, the second protection part and the supporting part, and the concave area is used for containing the bending area of the flexible screen body. According to the scheme disclosed by the invention, while curved surface display of the flexible display panel is ensured, the stress of the flexible screen body during bending is reduced, and the product yield is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a flexible display panel and a flexible display device. Background technique [0002] With the development of display technology, the display panel has been changing from large to large, from thin to thin, from narrow frame to frameless, from non-bendable to bendable, from curved to four-sided curved (that is, the display panel curved at the edges). The bending at the edge of the flexible display panel can not only realize the full-screen display at the front viewing angle, but also realize the display at the side, which improves the visual effect. [0003] In the prior art, when preparing a flexible display panel, the flexible screen is usually attached to a curved stainless steel substrate (SUS for short). However, since the surface shape of SUS is fixed, when the flexible screen body is bent along the surface shape of SUS, it will be subjected to d...
