Abstract
A display panel, a driving method for a display panel, and a display device. The display panel includes a display region, a non-display region, multiple sub-pixels, and at least one reused signal line; each sub-pixel includes a pixel circuit and a light-emitting device; in the pixel circuit, the initialization module is configured to write the initialization voltage to at least one of a control terminal of the drive module and an anode of the light-emitting device; in each sub-pixel, an input terminal of the initialization module in the pixel circuit and a cathode of the light-emitting device are connected to one reused signal line; and each reused signal line is configured to, in an initialization stage, provide the initialization voltage for the initialization module and in a light emission stage, provide the cathode voltage for the cathode of the light-emitting device.
