1. A display panel, comprising:
a display region and a frame region surrounding the display region, wherein the frame region includes a first region and a second region surrounding the first region;
a frame adhesive, located in the second region;
a padding metal, located in the second region, wherein along a direction perpendicular to a plane where the display panel is located, the padding metal at least partially overlaps the frame adhesive;
a cathode signal line at least surrounding a portion of the display region, wherein the cathode signal line is located in the first region;
a cathode layer located in the display region, wherein the cathode layer is connected to the cathode signal line; and
at least one connecting part connected to the padding metal, wherein the connecting part is located on a side of the padding metal adjacent to the first region, and is connected to the cathode signal line,
wherein a connecting part of the at least one connecting part is connected to the cathode signal line through a plurality of vias.
