Title:
FLEXIBLE DISPLAY PANEL AND PREPARATION METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/148909
Kind Code:
A1
Abstract:
The present disclosure provides a flexible display panel, a preparation method therefor, and a display device, which relate to the technical field of flexible displays, and can reduce the stress in a direction perpendicular to a bending surface subjected to a part of a signal lead wire located in a bending region when the flexible display panel is bent. In this way, the breakage of the signal lead wire upon bending is avoided, and the yield after bending is improved. The flexible display panel comprises: a flexible base substrate, the flexible base substrate comprising a first surface, the first surface comprising a bending area provided with a plurality of protrusions; and a signal lead wire located on a side of the first surface away from the flexible base substrate. The signal lead wire extends across the bending area and has a shape that substantially matches the plurality of protrusions. Figure 1
