Abstract: A pixel driving circuit includes a driving unit receiving a first control signal via a first control end, and the driving unit is biased according to the first control signal to provide a driving current to a light emitting element. One end of a capacitor is connected to a second control end of the driving unit, and the other end of the capacitor is connected to a first end or a second end of the driving unit. A compensation unit receives a second control signal via a first control end, and the compensation unit is biased according to the second control signal. A first switch unit receives a third control signal via a control end, and thereby the first switch unit is turned on. A second switch unit receives a fourth control signal via a control end, and thereby the second switch unit is turned on. A third switch unit receives a third control signal or a fourth control signal via a control end, and thereby the third switch uni
