Abstract
The present application provides a display panel, a manufacturing method, a detection method, and a display device. The display panel includes a display area and a non-display area surrounding the display area. The non-display area includes: a crack detection line surrounding the display area; a screen control line; a plurality of switch signal lines; and a plurality of detection switches electrically connected at different positions to the crack detection line. Each detection switch is also connected to the screen control line and a respective switch signal line, and allows conduction between the crack detection line and the screen control line based on the switch signal input by the switch signal line, such that the screen control line drives the display panel to display according to the test signal input by the crack detection line.
