In the pixel driving circuit, a cathode of a light-emitting device is connected to an output terminal of a driving module; during a first detection period, an anode of the light-emitting device is connected to a low electrical potential power signal; during a second detection period and a display period, the anode of the light-emitting device is connected to a high electrical potential power signal; and in a light-emitting phase of the display period, voltage values of the output terminals of the driving module are all within a preset range in the pixel driving circuit corresponding to different sub-pixels.
