Abstract
A display panel, a display device and a detection method are provided. The display panel includes a display area and a peripheral area surrounding the display area. Pixel units arranged in an array are disposed in the display area. The pixel unit includes a pixel driving circuit. A crack detecting line is disposed in the peripheral area, and the crack detecting line is connected to a reset signal terminal of the pixel driving circuit of at least one pixel unit. The display panel can reduce the influence of the voltage drop over the crack detection line on the brightness during the electrical detection stage, and can also improve the crack detection rate of the peripheral area.
