Abstract
The present disclosure provides a pixel driving circuit, a driving method thereof, and a display panel. A switching transistor and a sensing transistor are controlled with the same scanning line. In a detection stage, a voltage of a scanning signal line is adjusted to enable the sensing transistor to be turned on and the switching transistor to be turned off, so that a gate and a source of the driving transistor are in a floating state. A storage capacitor maintains a gate-source potential difference of the driving transistor to be stable, thereby it can accurately compensate for the mobility of the driving transistor.
