Embodiment Construction

[0027] 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.

[0028] As mentioned in the background technology, when the display panel structure in the prior art bends the non-display area of ​​the display panel, the bending radius is uncontrollable, and there is a risk of undesired stretching of the screen body, and the bending area The fixed bending state cannot be maintained, which leads to the problem that the metal traces in the bending area are easily broken and the reliability of the display panel is reduced. The inventors have found through research that the reason f...

Abstract

The invention discloses a display panel and a display device. The display panel comprises a flexible substrate, and the flexible substrate comprises a display area and a bending area positioned on atleast one side of the display area. The part, positioned in the bending area, of the flexible substrate is bent towards one side far away from the light-emitting face of the display panel, a support module is arranged at the bending inner side of the bending area, a first surface of the support module is bonded to the flexible substrate through a first bonding layer, the first surface is an arc-shaped surface, the radius of the first surface is equal to the bending radius of the bent area, thus the bending radius of the bending area can be accurately controlled, then the excessive stretching when the flexible substrate is bent is prevented, meanwhile, the support module can carry out support protection on the bending area, so that the dead bending of the bending area is prevented, the linebreakage of the bending area is avoided, and the reliability of the display panel is improved.

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, narrow borders and high screen-to-body ratio of display panels have become a major trend. [0003] In order to realize the narrow frame and high screen-to-body ratio of the display panel, it is necessary to bend the non-display area of ​​the display panel to the side opposite to the light-emitting surface. However, in the prior art, when bending the non-display area, the bending radius is uncontrollable, there is a risk of undesired stretching of the screen, and the bending area cannot maintain a fixed bending state, resulting in the metal in the bending area The wires are easily broken, reducing the reliability of the display panel. Contents of the invention [0004] The present invention provides a display panel and a display device, wh...
