1. A display panel, comprising:
a driving backplane having a pixel driving region and a peripheral region surrounding the pixel driving region, the peripheral region being provided with bonding pads, an edge of the driving backplane being surrounded by a first section and a second section, and the bonding pads being located between the first section and the pixel driving region;
a plurality of detection pads disposed in the second section and distributed along the second section;
a light emitting function layer disposed on the driving backplane and located in the pixel driving region;
a flexible circuit board extending between the first section and the pixel driving region, and being bonded to the bonding pads;
a first packaging layer disposed on a side of the light emitting function layer away from the driving backplane; and
an orthographic projection of the first packaging layer on the driving backplane covers the pixel driving region and the detection pads.
