Abstract: A display panel. The display panel includes a base substrate, drive circuits, pixel circuits, and signal line groups. The drive circuits and the pixel circuits are arranged on the base substrate. The drive circuits provide control signals for the pixel circuits. The pixel circuits provide drive currents for light-emitting elements of the display panel. The drive circuits include a first drive circuit and a second drive circuit. The signal line groups include a first signal line group and a second signal line group. The first signal line group includes M signal lines that provide signals for the first drive circuit. The second signal line group includes N signal lines that provide signals for the second drive circuit, M≥1, and N≥1. The first drive circuit provides a light-emitting control signal for a light-emitting control transistor of the pixel circuit.

Abstract: 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.
