Embodiment Construction

[0038] 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.

[0039] As mentioned in the background art, the existing display panels have the problems of uneven folding area and lack of support. After research, the inventors found that in order to realize the bending performance of the existing foldable display device in the folding area, it is necessary to carry out Punching, after punching with a large opening ratio, will result in insufficient support area of ​​the folding area, weakening the support for the display panel, causing unevenness of the folding area, and affect...

Abstract

The invention discloses a display panel and a display device. The display panel is divided into at least two non-folding areas and folding areas arranged between the adjacent non-folding areas. The display panel comprises a substrate, a supporting layer and a display function layer, wherein the supporting layer and the display function layer are arranged on two sides of the substrate; the supporting layer comprises a first rigid material layer, the first rigid material layer comprises a groove located in the folding area, at least one second rigid material layer is arranged in the groove, and the second rigid material layer is connected with the bottom of the groove; and the thickness of the second rigid material layer is smaller than the depth of the groove. According to the technical scheme, the thickness of the second rigid material layer is smaller than the depth of the groove, the second rigid material layer with the smaller thickness is good in supporting performance and long in folding service life, the number of times of folding resistance of the supporting layer is increased, the supporting area of the folding area is large, the flatness of the folding area is improved, and the problems that an existing display panel is uneven in folding area and lacks supporting are solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology and the improvement of people's living standards, the requirements for display panels are getting higher and higher, and foldable display screens have become a development trend. The existing foldable display devices have the problems of uneven folding area and lack of support. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device to solve the problems of uneven folding areas and lack of support in existing display panels. [0004] In order to achieve the above technical problems, the present invention adopts the following technical solutions: [0005] In a first aspect, an embodiment of the present invention provides a display panel, where the display panel is divided into at ...
