Problems solved by technology

[0005] However, when the flexible display device is bent, the structure of the metal film layer and the organic film layer is subjected to uneven stress, and the film layer is prone to peeling off under the action of stress, resulting in damage to the flexible display device.
It can be seen that the structural stability of the non-display area of ​​the existing flexible display device is not high

Abstract

The present invention provides an array substrate and a flexible display device. The non-display area of ​​the array substrate is stacked with a planarization film layer and a metal film layer, and an embedded film is arranged between the planarization film layer and the metal film layer. Bump fit structure. Compared with the originally flat contact surface between the planarization film layer and the metal film layer, the concave-convex matching structure of this embodiment increases the contact area between the planarization film layer and the metal film layer, and increases the adhesion between the two surfaces. Attachment. Moreover, the fit of the concave-convex matching structure increases the relative limit ability of the film layer in the horizontal direction, improves the uneven stress on the planarization film layer and the metal film layer when the array substrate is bent, and reduces the stress of the planarization film layer and the metal film layer. The possibility of peeling off the metal film layer improves the structural stability of the array substrate, and further improves the stability of the flexible display device using the array substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a flexible display device. Background technique [0002] A flexible display device is a deformable and bendable display device, which has the advantages of portability, convenience, bendability, and the like. The array substrate is one of the key components of the flexible display device. In order to increase the display area of ​​the flexible display device, one of the more commonly used methods is to permanently keep the non-display area of ​​the array substrate bent, thus improving the non-display area of ​​the array substrate. Structural stability is very necessary. [0003] The array substrate includes a display area and a non-display area, and an organic light-emitting layer is arranged in the pixel definition layer above the display area. The non-display area usually includes a flexible substrate layer, a channel formation layer, an insula...
