Abstract: A display substrate has a display region, a peripheral region surrounding the display region, and pad regions on a first connection side of the peripheral region and distal to the display region. The display region includes sub-pixel regions. The display substrate further includes: a base, and organic light-emitting diodes and a first power supply line all on the base. The organic light-emitting diodes are provided in the sub-pixel regions, respectively. A cathode of each organic light-emitting diode extends from the display region to the peripheral region and is connected to the first power supply line in the peripheral region. The first connection side includes a first connection region corresponding to a position between two adjacent pad regions, and a second connection region other than the first connection region. A connection region between the first power supply line and the cathode covers at least part of the second connection region.

Abstract: A flexible substrate, a preparation method therefor and a flexible display substrate. The flexible substrate comprises a plurality of spaced island regions and a plurality of bridge regions connected between different island regions, and has a plurality of openings in non-island regions and non-bridge regions. Each island region is provided with a plurality of layered structures. Each layered structure comprises, sequentially arranged from bottom to top: a first flexible base layer, a first buffer layer and a second flexible base layer, wherein the orthographic projection of the surface of the side of the first buffer layer facing the first flexible base layer on the first flexible base layer is greater than that of the surface of the side of the first flexible base layer facing the first buffer layer on the first flexible base layer.

Abstract: A flexible display panel, a manufacturing method thereof and a flexible display device, which relate to the technical field of flexible display and reduce the probability of the occurrence of cracks on an inorganic encapsulation structure when a flexible display panel is bent, so that the service life of light emitting devices in the flexible display substrate is prolonged. The flexible display panel includes a flexible display substrate and an encapsulation structure arranged on a surface of the flexible display substrate. A portion of the encapsulation structure corresponding to a non-display region is an inorganic encapsulation structure. The flexible display panel further includes an organic encapsulation layer covering the inorganic encapsulation structure. The manufacturing method of a flexible display panel manufacture the flexible display panel described in the above technical solutions. The flexible display panel provided by the present disclosure is used in a flexible display device.
