1. A display panel comprising a display area and a non-display area located at least one side of the display area, wherein the non-display area comprises a transfer area and a binding area, the transfer area is located at a side of the binding area close to the display area, and the transfer area comprises:
a first transfer unit electrically connected with a first ground line in the display area; and
a second transfer unit electrically connected with a first touch signal line in the display area,
wherein the binding area comprises a first binding pad and a second binding pad, and the first binding pad and the second binding pad are configured to connect with a flexible circuit board or a drive chip,
wherein the first transfer unit and the first binding pad are electrically connected through a second ground line located in the non-display area, and the second transfer unit and the second binding pad are electrically connected through a second touch signal line located in the non-display area, and
wherein an impedance of the second ground line is smaller than an impedance of the second touch signal line.
