Embodiment 1

[0038] Figure 3a It is a schematic plan view of the flexible display panel in Embodiment 1 of the present invention. To simplify the drawing, here only reflects the planar structure of three sub-pixels. In fact, the number of sub-pixels of the flexible display panel is not limited to this. Such as Figure 3a As shown, the flexible display panel includes scan lines Sn, data lines Dm and power lines formed on the flexible substrate 100, the scan lines Sn and data lines Dm define a plurality of sub-pixels arranged in a matrix, each sub-pixel Including at least one storage capacitor Cs. In this embodiment, the upper plate Cs-2 of the storage capacitor Cs has a mesh structure, and the lower plate Cs-1 of the storage capacitor Cs has a flat plate structure. By adopting the mesh structure, the fracture phenomenon of the upper plate Cs-2 can be greatly reduced or even eliminated, and the working reliability of the flexible display panel is improved.

Embodiment 2

[0053] Figure 4a is a schematic plan view of the flexible display panel in Embodiment 2 of the present invention, Figure 4b yes Figure 4a A schematic cross-sectional view of one sub-pixel in Fig. Such as Figure 4a and Figure 4b As shown, the main structure of the flexible display panel includes scan lines Sn, data lines Dm and power lines formed on the flexible substrate 100, the scan lines Sn and data lines Dm define a plurality of sub-pixels arranged in a matrix, Each sub-pixel includes at least one storage capacitor Cs. In this embodiment, the upper plate Cs-2 of the storage capacitor Cs has a planar structure, and the lower plate Cs-1 of the storage capacitor Cs has a mesh structure. By adopting the mesh structure, the fracture of the lower plate Cs-1 can be greatly reduced or even eliminated. Wherein, the meshes of the lower plate Cs-1 are preferably diamond-shaped, but it should be understood that the present invention does not limit the shape, size and layout...

Embodiment 3

[0055] Figure 5a is a schematic plan view of the flexible display panel in Embodiment 2 of the present invention, Figure 5b yes Figure 5a A schematic cross-sectional view of one sub-pixel in Fig. Such as Figure 5a and Figure 5b As shown, in this embodiment, both the upper plate Cs-2 and the lower plate Cs-1 of the storage capacitor Cs are of mesh structure, thus, the upper plate Cs-2 and the lower plate Cs-1 can be greatly reduced or even eliminated at the same time. The phenomenon that the lower plate Cs-1 is broken. Further, the mesh positions of the upper pole plate Cs-2 and the lower pole plate Cs-1 are arranged facing each other, so as to maximize the overlapping area of ​​the upper pole plate Cs-2 and the lower pole plate Cs-1. In this embodiment, the size of the mesh of the upper pole plate Cs-2 and the mesh of the lower pole plate Cs-1 are the same, but it should be recognized that the mesh of the upper pole plate Cs-2 is the same as that of the lower pole pl...

Abstract

The invention provides a flexible display panel, a fabrication method thereof and a flexible display device. An upper pole plate and / or a lower pole plate of at least one part of storage capacitor in at least one part of sub-pixel of the flexible display panel is of a mesh structure. With the adoption of the pole plate in the mesh structure, the phenomenon that the pole plate is broken can be substantially reduced or even eliminated. Moreover, the flexible display panel also comprises a repair line, the repair line is connected with two ends of the lower pole plate of the storage capacitor, so that a drain of a switch transistor and a grid of a driving transistor are enabled to be maintained connected all the way when the lower pole plate is broken.

Description

technical field [0001] The present invention relates to the technical field of displays, in particular to a flexible display panel, a manufacturing method of the flexible display panel, and a flexible display device. Background technique [0002] With the development of the information society, people's demand for display devices is increasing day by day. Flexible display panels are increasingly favored by people because of their thinness, bendability or even curling, and good mechanical properties. At present, flexible display panels are more and more widely used in daily life. [0003] Flexible display panels include flexible liquid crystal display (LCD) devices and flexible organic light emitting diode display (OLED) devices. Flexible display panels are usually fabricated on flexible carriers, which pose great challenges to their design and fabrication due to their bending characteristics. [0004] In flexible LCD devices and flexible OLED devices, storage capacitors a...
