Embodiment 1

[0035] Please refer to figure 2 , which is a schematic structural diagram of a flexible display device according to Embodiment 1 of the present invention. like figure 2 As shown, the flexible display device 20 includes: a flexible substrate (not shown in the figure) and a metal wire disposed on the flexible substrate, and a part of the metal wire is an arc-shaped segment.

[0036] Specifically, the metal lines include a plurality of data lines 22 and a plurality of gate lines 24 that are intersected and independent from each other. The plurality of data lines 22 and several gate lines 24 form a plurality of intersection nodes, and each adjacent At least one first arc line segment 28a, at least one second arc line segment 28b, and a straight line segment 28c connected to the first arc line segment 28a and the second arc line segment 28b are arranged between the intersection nodes, and the straight line The cross-section and longitudinal section of the segment 28c are straig...

Embodiment 2

[0061] Please refer to Figure 5 , which is a schematic structural diagram of a flexible display device according to Embodiment 2 of the present invention. like Figure 5 As shown, the flexible display device 20 includes: a flexible substrate (not shown in the figure) and a metal wire disposed on the flexible substrate, and a part of the metal wire is an arc-shaped segment.

[0062] Specifically, the metal lines include a plurality of data lines 22 and a plurality of gate lines 24 that are intersected and independent from each other. The plurality of data lines 22 and several gate lines 24 form a plurality of intersection nodes, and each adjacent At least one helical arc line segment 28d is arranged between the intersection nodes.

[0063] The difference between this embodiment and Embodiment 1 is that the shape of the arc-shaped segment in the metal wire is helical, and the helical arc-shaped segment can bear stress in both the cross-sectional direction and the longitudinal...

Abstract

The present invention provides a flexible display device and a manufacturing method thereof, wherein the flexible display device comprises a flexible substrate and a metal line arranged on the flexible substrate, and a part of the metal line is an arc-shaped line segment. According to the flexible display device and the manufacturing method thereof provided by the present invention, by setting a part of line segment of the metal line as the arc-shaped line segment, the stress bearing capability of the metal line is improved, thereby prolonging the usage times of the metal line, and improving the service life of the flexible display device. Further, the arc-shaped line segment adopts an up-down fluctuation structure and a plane bending structure which are arranged alternatively, so that the break risk of the metal line is reduced further, and the reliability of the flexible display device is improved.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] A flexible display is a deformable or bendable display device fabricated on a flexible carrier (also called a flexible substrate). Due to the characteristics of high lightness, impact resistance, flexibility, wearability, and portability, flexible displays are known as one of the most promising products in the 21st century and have been increasingly favored by people. focus on. [0003] At present, flexible displays usually include a display panel and peripheral circuits for driving the display panel. The display panel includes a flexible substrate, a pixel array and metal lines, and the pixel array and metal lines are all arranged on the flexible substrate. The peripheral circuit is electrically connected to each pixel unit of the pixel array through the metal lines, and the metal line...
