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
[0037] 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 herein 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, the drawings only show some but not all structures related to the present invention.
[0038] At the same time, the drawings and descriptions of the embodiments are illustrative rather than restrictive. The same reference numbers refer to the same elements throughout the specification. Additionally, the thickness of some layers, films, panels, regions, etc., may be exaggerated in the drawings for understanding and ease of description. It will also 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 int...

The invention discloses a flexible display panel and a flexible display device. The flexible display panel includes: a support substrate, and a flexible screen body disposed on the support substrate; wherein the support substrate includes a non-bending area and at least one bending area, and the bending area includes a first sub-area and a second sub-area, The first sub-region is located between the second sub-region and the non-bending region, and is adjacent to the second sub-region and the non-bending region respectively; the elastic modulus of the first sub-region is greater than the elastic modulus of the second sub-region, The stiffness of the first subregion is greater than the stiffness of the second subregion. The solution disclosed in the present invention can reduce the uneven stress when the flexible screen body is bent while ensuring the curved display of the flexible display panel.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a flexible display panel and a flexible display device. Background technique [0002] With the development of display technology, display panels have been constantly changing from large to large, from thin to thin, from narrow bezels to no bezels, from non-bendable to bendable, from curved to four-sided curved (that is, the display panel's curved at the edges). The bending at the edge of the flexible display panel can not only achieve full-screen display with a frontal viewing angle, but also display on the side, which improves the visual effect. [0003] In the prior art, when preparing a flexible display panel, the flexible screen body is usually attached to a stainless steel substrate (SUS for short) in the form of a curved surface. However, since the curved shape of SUS is fixed, when the flexible screen body is bent along the curved shape of S...
