1. A flexible array substrate, comprising at least one stretchable region; wherein the flexible array substrate is provided with a plurality of through holes within the stretchable region, and the plurality of through holes divide the stretchable region into a pixel island area for displaying and a bridging area for signal transmission; the bridging area comprises a source-drain bridging area, and the flexible array substrate, in the source-drain bridging area, comprises:
a base substrate;
a first source-drain metal layer, provided on one side of the base substrate, and comprising a plurality of first source-drain leads;
a first insulating material layer, provided on one side of the first source-drain metal layer away from the base substrate;
a second source-drain metal layer, provided on one side of the first insulating material layer away from the base substrate; wherein the second source-drain metal layer comprises a plurality of second source-drain leads, and a number of the second source-drain leads is less than a number of the first source-drain leads;
a second insulating material layer, provided on one side of the second source-drain metal layer away from the base substrate; wherein the second insulating material layer is provided with a plurality of isolation grooves, and an orthographic projection of the isolation grooves on the second source-drain metal layer isolates the second source-drain leads and the through holes; and
an encapsulation layer, provided on one side of the second insulating material layer away from the base substrate.
