1. A display panel, comprising:

  • a base substrate, including a display region and a non-display region;

    a pixel array, disposed in the display region; and

    at least one fingerprint recognition unit, located in the non-display region and sharing the base substrate with the pixel array, wherein;

    each fingerprint recognition unit includes a fingerprint recognition sensor, wherein the fingerprint recognition sensor includes a first electrode layer, a P-type-semiconductor/insulator/N-type-semiconductor (PIN) layer, and a second electrode layer disposed in a sequential order, and the first electrode layer includes a transparent electrode material,the non-display region includes a step bending region and a fingerprint recognition region, wherein the fingerprint recognition region is located on a side of the step bending region away from the display region, and the at least one fingerprint recognition unit is located in the fingerprint recognition region, andthe display panel is folded at the step bending region, wherein after the display panel is folded, the first electrode layer of each fingerprint recognition unit is located on a side surface of the PIN layer close to a light-emitting surface of the display panel, and a folding direction of the display panel is opposite to a light-emitting direction of the display panel.
