1. A display panel, comprising:
a substrate, and a plurality of gate electrode lines, a plurality of data lines and a plurality of heating wirings which are at least in a display region of the display panel, wherein the plurality of gate electrode lines extends along a first direction and is arranged along a second direction; the plurality of data lines extends along the second direction and is arranged along the first direction; the first direction intersects the second direction; and the display panel further includes a non-display region at least partially surrounding the display region;
a control chip, in the non-display region on a first side of the display panel, wherein the control chip is at least electrically connected to a data line of the plurality of data lines; and along the second direction, the first side is adjacent to the display region and below the display region;
a heating drive element, in the non-display region on the first side such that the control chip and the heating drive element are on the same side of the display panel, wherein the heating drive element is electrically connected to a heating wiring of the plurality of heating wirings through a heating bus; and
a gate drive element, in the non-display region on a second side of the display panel, wherein the second side is adjacent to the first side; and the gate drive element is electrically connected to a gate electrode line of the plurality of gate electrode lines and electrically connected to the control chip through a first lead, wherein:
the display panel further includes:
a first metal layer, a second metal layer and a third metal layer which are disposed on the substrate, wherein along a direction perpendicular to the substrate, two adjacent metal layers are separated by an insulating layer; the heating bus is in at least one of the first metal layer, the second metal layer and the third metal layer; the heating wiring and at least a part of the heating bus are disposed in different layers; and the heating wiring is electrically connected to the heating bus through a connection hole or a connecting bridge.
