Flexible array substrate and preparation method thereof and display device

Abstract

An embodiment of the invention provides a flexible array substrate and a preparation method thereof and a display device and relates to the display technical field. The probability of breakage of signal lines in a bending region due to bending can be reduced. The flexible array substrate comprises a display region and a wiring region. The wiring region comprises a bending region adjacent to the display region. The bending region comprises signal lines arranged on a substrate and a protection layer. The protection layer is arranged at one side, away from the substrate, of the signal lines; andthe orthographic projection of the protection layer on the substrate and the orthographic projection of the signal lines on the substrate have an overlapped region, and Young modulus of the protectionlayer is larger than or equal to Young modulus of the signal lines.

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] Such as 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 ...

Problems solved by technology

[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 In the direction of the middle arrow A), it is easy to cause the signal line 100 in the bending area 10 to break, thus resulting in poor display of the flexible display device.
