1. A display panel, comprising:
a driving backplate having a light-transmitting region and a driving region at least partially surrounding outside of the light-transmitting region, wherein the driving region has a plurality of pixel circuits, the plurality of pixel circuits comprise first pixel circuits and second pixel circuits, the driving backplate has a plurality of first interconnection holes, and any one of the pixel circuits is connected to one of the first interconnection holes;
an interconnection layer arranged on a side of the driving backplate and covering the light-transmitting region and the driving region, wherein:
the interconnection layer comprises a plurality of lead layers which are mutually apart from each other, and each of the lead layers comprises a plurality of leads which are mutually apart from each other;
the interconnection layer has an interconnection region corresponding to the light-transmitting region and a wiring region corresponding to the driving region, and the interconnection region comprises two interconnection portions separated on both sides of a first central axis;
the first central axis is a central axis of the interconnection region extending along a column direction;
each of the interconnection portions has a plurality of second interconnection holes, and any one of the second interconnection holes is connected with one of the first interconnection holes through one of the leads; and
a light-emitting layer arranged on a side of the interconnection layer away from the driving backplate and comprising a plurality of light-emitting devices, wherein the light-emitting devices comprise a plurality of first light-emitting devices in the interconnection portions and a plurality of second light-emitting devices in the wiring region, any one of the first light-emitting devices is connected to one of the second interconnection holes, and any one of the second light-emitting devices is connected to one of the first interconnection holes;
wherein the first interconnection holes and the second interconnection holes are arranged in a plurality of hole rows distributed along the column direction, the second interconnection holes are arranged in a part of the hole rows, a first interconnection hole and a second interconnection hole which are connected to a same lead are in a same hole row to form a hole group; in two adjacent hole groups, a first interconnection hole and a second interconnection hole in one of the two adjacent hole groups are arranged between a first interconnection hole and a second interconnection hole in another one of the two adjacent hole groups;
wherein a length of any one of the leads in a row direction is the same as a distance between a first interconnection hole and a second interconnection hole which are connected to the lead, or the length of any one of the leads in the row direction differs from the distance between the first interconnection hole and the second interconnection hole which are connected to the lead by a specified length.
