Abstract: A pixel driving device includes a capacitance, a reset circuit, a compensation circuit, a driving transistor and a first transistor. Reset circuit and compensation circuit are coupled to a first end and a second end of capacitance. First transistor is coupled between second end of driving transistor and second end of capacitance. Reset circuit resets first end of capacitance at a power supply voltage and reset second end of capacitance at a reference voltage according to a first sweep signal respectively. Compensation circuit writes a data voltage into first end of capacitance via driving transistor and second end of capacitance is maintained at reference voltage according to a second sweep signal. First transistor generates a driving voltage difference between first end and second end of capacitance according to a control signal. Driving transistor outputs a current to a luminous element according to driving voltage difference.
