1. A flexible display panel, comprising:
an elastic substrate;
a plurality of main pixel islands arranged on the elastic substrate, the main pixel islands comprising a plurality of main pixel units; and
a plurality of auxiliary pixel islands arranged on the elastic substrate and disposed between the main pixel islands, the auxiliary pixel islands comprising a plurality of auxiliary pixel units;
wherein when the elastic substrate is in a natural state, the main pixel islands adjacent to the auxiliary pixel islands are close to the auxiliary pixel islands, and the main pixel islands enclose a light emitting side of the auxiliary pixel islands to accommodate the auxiliary pixel islands; and when the elastic substrate is in a stretched state, the main pixel islands adjacent to the auxiliary pixel islands are away from the auxiliary pixel islands to expose the auxiliary pixel islands;
wherein each of the main pixel islands comprises a first main body, at least one of the main pixel units is disposed on one side of each first main body away from the elastic substrate, each of the auxiliary pixel islands comprises a second main body, and at least one of the auxiliary pixel units is disposed on one side of each second main body away from the elastic substrate;
wherein a distance between one end of each first main body away from the elastic substrate and the elastic substrate is greater than a distance between one end of each second main body away from the elastic substrate and the elastic substrate; and when the elastic substrate is in the natural state, an orthographic projection of one end of each first main body away from the elastic substrate projected on the elastic substrate is partially overlapped with an orthographic projection of the adjacent second main body projected on the elastic substrate;
wherein each of the first main bodies comprises a first rigid substrate and a support pillar, the support pillar is disposed on one side of the first rigid substrate away from the elastic substrate, and each of the second main bodies comprises a second rigid substrate; and a distance between one end of each support pillar away from the elastic substrate and the elastic substrate is greater than a distance between one end of each second rigid substrate away from the elastic substrate and the elastic substrate.
