Problems solved by technology

[0003] In the related art, the flexible display panel includes a multi-layer film stack structure. When the flexible display panel is bent, each layer of film has different bending stresses due to the different distances from the neutral plane, and when the flexible display panel has multiple bending In the bending direction, the bending stress of each film layer is more complicated. Due to different bending stresses, each film layer may be bent to different degrees, resulting in the phenomenon of peeling and cracking between the film layers. It is necessary to provide a New flexible display panels to improve the bending characteristics of the panel to withstand smaller bending radii

Embodiment Construction

[0066] The present application will be further described in detail below through specific embodiments in conjunction with the drawings.

[0067] It should be noted that the “upper”, “lower”, “left”, “right” and other directional words described in the embodiments of this application are described from the angle shown in the drawings, and should not be construed as implementation of this application Limitations of examples. In addition, in the context, it should also be understood that when it is mentioned that an element is formed "on" or "under" another element, it can not only be directly formed "on" or "under" the other element, but also It may be formed "on" or "under" another element indirectly through an intermediate element.

[0068] Please refer to figure 1 , figure 1 A partial cross-sectional view of the display panel is shown.

[0069] The present application provides a flexible display panel 2, which includes a first film layer 202 and a second film layer 204, the first ...

Abstract

The invention relates to a flexible display panel and a display device. The display panel comprises a first film, a second film, a first area and a second area, the elastic modulus of the first film is larger than that of the second film in the first area, and the elastic modulus of the first film is smaller than that of the second film in the second area. When the flexible display panel is bent,the positions of the first film and the second film in the display panel are different, and the first film and the second film are different in deformation during bending. Therefore, bending stress applied to the first film and the second film with corresponding different elastic modulus is balanced, the bending property of the flexible display panel is improved, and the flexible display panel canbear a smaller bending radius.

Description

Technical field [0001] This application relates to the field of display technology, and in particular to a flexible display panel and a display device. Background technique [0002] With the development of science and technology, portable devices have become a new development trend in modern society, and are gradually changing human lives and bringing major changes to science and technology. In particular, flexible display panels are increasingly favored by users due to their advantages such as foldability, portability, and wide application range, and provide users with a brand-new viewing experience. [0003] In the related art, the flexible display panel includes a multi-layer film stack structure. When the flexible display panel is bent, due to the different distances from the neutral surface of each layer of the film, the bending stresses are different, and when the flexible display panel has multiple bends When bending the direction, the bending stress of each film layer is m...
