Problems solved by technology

With the development of display products, the introduction of 100μm-150μm metal sheet structure has greatly improved the bending performance of the display; however, in the process of product development, it was found that the design of metal sheet with foam structure has simultaneously increased the difficulty of the process ; and recent research and investigations have found that after a large number of bending times, the display screen may not be able to return to a straight state, and the bending area of ​​the display screen has wrinkles and uneven surfaces

Abstract

The invention discloses a display panel and a display device. The display panel comprises a display panel main body, a back plate layer which is positioned on one side of the display panel main body, and a supporting layer which is located on the side, away from the display panel body, of the backboard layer, wherein the backboard layer comprises a first backboard located on the side, close to the display panel body, of the supporting layer, a buffer layer located on the side, away from the supporting layer, of the first backboard, and a second backboard located between the buffer layer and the display panel body. The display panel comprises the integrated structure formed by combining the back plate and the buffer layer, and problems of wrinkles and uneven surface caused by multiple times of bending of the display panel are solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Flexible display screens have the advantages of thinness, non-fragility, and bendability, and flexible display screens have received more and more attention. The flexible display screen has a flat state and a curved state, and users can repeatedly bend the flexible display panel. In existing flexible display screens, a buffer layer and a protective layer such as a backplane and a metal sheet are usually arranged under the display screen. With the development of display products, the introduction of 100μm-150μm metal sheet structure has greatly improved the bending performance of the display; however, in the process of product development, it was found that the design of metal sheet with foam structure has simultaneously increased the difficulty of the process ; and recent research and investigations ha...
