Claim 0:
1. A display panel, comprising:
a base substrate, having a first through hole;
a conductive structure, located on the base substrate and at least partially covering the first through hole, wherein the conductive structure comprises a plurality of block structures, to facilitate connection to a plurality of contacts on a control integrated circuit (IC);
a display structure, comprising a first display structure, a control line, and a second display structure that are arranged in layers on a side of the base substrate where the conductive structure is located, wherein the first display structure has a second through hole, and the control line is electrically connected to the conductive structure by passing through the second through hole;
a fingerprint recognition assembly, comprising a perforated light-shielding layer and a fingerprint recognition sensor, wherein the conductive structure and the perforated light-shielding layer are structures located in a same layer, and the fingerprint recognition sensor is located on a side, distal from the display structure, of the perforated light-shielding layer; wherein the perforated light-shielding layer is provided with a plurality of apertures, and light emitted by the display structure and then reflected by a touch object passes through the plurality of apertures and is sensed by the fingerprint recognition sensor; and
a base layer located between the conductive structure and the first display structure, wherein the base layer has a third through hole in communication with the second through hole of the first display structure, and the control line is electrically connected to the conductive structure by passing through the second through hole and the third through hole;
wherein the first through hole, the second through hole, and the third through hole are coaxial;
the base substrate comprises a first polyimide structure layer and a first silicon oxide barrier layer that are arranged in layers along a direction close to the display structure, and the first through hole passes through the first polyimide structure layer and the first silicon oxide barrier layer;
the base layer comprises a second polyimide structure layer and a second silicon oxide barrier layer that are arranged in layers along the direction close to the display structure, and the third through hole passes through the second polyimide structure layer and the second silicon oxide barrier layer; and
the conductive structure and the perforated light-shielding layer are disposed between the first silicon oxide barrier layer and the second polyimide structure layer.
