More Information
Summary:A display panel includes a base substrate, including a display region and a non-display region; a pixel array in the display region; and at least one fingerprint recognition unit, located on the base substrate in the non-display region. Each fingerprint recognition unit includes a fingerprint recognition sensor, including a first electrode layer, a P-type-semiconductor/insulator/N-type-semiconductor (PIN) layer, and a second electrode layer. The first electrode layer includes a transparent electrode material. The non-display region includes a step bending region, and a fingerprint recognition region located on the side of the step bending region away from the display region. The at least one fingerprint recognition unit is located in the fingerprint recognition region. The display panel is folded at the step bending region. The first electrode layer of each fingerprint recognition unit is located on the side surface of the PIN layer close to the light-emitting surface of the display panel.
