    Abstract: A display panel has a mounting hole. The display panel includes a first conductive layer, a second conductive layer, and a first insulating isolation layer located between the first conductive layer and the second conductive layer. The first conductive layer includes a first crack detection line and a first electrode connected to each other. The second conductive layer includes a second crack detection line and a second electrode connected to each other. The first electrode and the second electrode constitute a capacitor. The mutual-sensing capacitor is disposed outside of the mounting hole. The capacitor is configured to detect whether there is a crack in a portion of the display panel located around the mounting hole.
