1. A display panel, comprising:
a touch electrode layer at least partially in a display area of the display panel;
a gate-on-array in a peripheral area of the display panel; and
a crack detection circuit;
wherein at least a portion of signal lines in the crack detection circuit comprises a metal line in a same layer as mesh lines of the touch electrode layer;
the crack detection circuit comprises an integrated circuit and a first conductive loop electrically connected to the integrated circuit; and
the first conductive loop comprises a first touch crack sub-loop and a first panel crack sub-loop connected to each other, at least a portion of the first touch crack sub-loop being in a same layer as the mesh lines of the touch electrode layer; at least a portion of the first panel crack sub-loop being in a same layer as a gate line of the display panel.
