A flexible array substrate, its preparation method, and a display device

Abstract

Embodiments of the present invention provide a flexible array substrate, a preparation method, and a display device, which relate to the field of display technology, and can reduce the probability of breakage of signal lines in a bending area due to bending. The flexible array substrate includes a display area and a wiring area, and the wiring area includes a bending area adjacent to the display area; the bending area includes a signal line and a protective layer arranged on the base substrate , the protection layer is located on the side of the signal line away from the base substrate; wherein, the orthographic projection of the protection layer on the base substrate is the same as the orthographic projection of the signal line on the base substrate The projections have overlapping areas, and the Young's modulus of the protective layer is greater than or equal to the Young's modulus of the signal line.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible array substrate, a preparation method, and a display device. Background technique [0002] Flexible display devices have been increasingly used in wearable devices, electronic paper and other fields in recent years due to their thinness, lightness, and bendability. [0003] like figure 1 As shown, the flexible display device includes a wiring area 01 and a display area 02, and a bending area (Bending Area) 10 is provided at a position adjacent to the display area 02 in the wiring area 01. By bending the bending area 10, the Realize the narrow frame design of flexible display devices; such as figure 2 ( figure 1 As shown in the cross-sectional schematic diagram along the arrow B direction), the bending area 10 is provided with a signal line 100, so when bending (see figure 1 During the process in the direction of the middle arrow A), the signal line 100 in the ben...
