Display panel, method for driving display panel, driving circuit and display device

A display panel includes a display area, a non-display area surrounding the display area and including a bending area, and a power line that includes an extension part located at least partially in the bending area and a body part located in the non-display area and electrically connected to the extension part. The body part is located between the bending area and the display area. The display area includes first and second boundaries opposite to each other in a first direction, and a centerline extending in a second direction pointing from the display area to the bending area and intersecting the first direction. In the first direction, a minimum distance between the extension part and the first boundary is smaller than a minimum distance between the extension part and the second boundary and is smaller than or equal to a minimum distance between the extension part and the centerline.
