Problems solved by technology

[0003] However, when the flexible display device is bent, the bending area will bear too concentrated stress, which will cause problems such as cracking, peeling and dislocation of the film layers of the array substrate in the flexible display device, which will affect the display performance of the flexible display device.

Embodiment Construction

[0023] 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.

[0024] figure 1 is a schematic structural diagram of an array substrate in the prior art, such as figure 1 As shown, the array substrate includes a bending area 11, and also includes a flexible substrate 20, an inorganic insulating layer 30, and a metal wiring 60. When the array substrate is bent, the bending area 11 will bear excessively concentrated stress. The inorganic insulating layer 30 in the folding region 11 has a high hardness, so that the stress in the array substrate cannot be released, resulting in p...

Abstract

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises a bending region, and further comprises a flexible substrate; an inorganic insulation layer located at one side of the flexible substrate, wherein an opening structure is formed at a part corresponding to the bending region in the inorganic insulation layer, and the opening structure penetrates through the inorganic insulation layer on a direction vertical to a plane at which the flexible substrate is located; an organic material layer at least partially filled in the opening structure; a metal wiring located at one side, far away from the flexible substrate, of the organic material layer; and an anti-bending water-oxygen barrier layer at least located in the opening structure, and located between the metal wiring and the flexible substrate on the direction vertical to the plane at which the flexible substrate is located. Through the array substrate provided by the embodimentof the invention, the problem of stress concentration when the array substrate is bent can be reduced, and the corrosion in the metal wiring in the array substrate by the water oxygen can be prevented, and the normal display performance of the display panel is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to an array substrate, a display panel, and a display device. Background technique [0002] With the continuous development of display technology, flexible display devices are favored by more and more users due to their lighter and thinner design, wider viewing angle, faster response speed and lower power consumption. . [0003] However, when the flexible display device is bent, the bending area will bear too concentrated stress, which will cause problems such as cracking, peeling and dislocation of the film layers of the array substrate in the flexible display device, which will affect the display performance of the flexible display device. Contents of the invention [0004] Embodiments of the present invention provide an array substrate, a display panel, and a display device, which can reduce the stress concentration of the array substrate when it ...
