Pixel driving circuit, driving method thereof and display device

A pixel driving circuit for driving a light-emitting unit, comprising:

• a driving unit connected to the light-emitting unit;
• a capacitor unit, one end of the capacitor unit is connected to the driving unit, and a second end of the capacitor unit is connected to a power source signal input end;
• a data write-in unit connected to a corresponding gate line in a row direction, a corresponding data line in a column direction and the driving unit;
• a power source control unit connected to a first light-emitting control end, the power source signal input end and the driving unit;
• and
• a first light-emitting control unit connected to a second light-emitting control end, the power source signal input end and the driving unit, and configured to, within a predetermined time period of a light-emitting stage, control the power source signal input end to be electrically connected to the driving unit under the control of the second light-emitting control end, stop the operation of the driving unit, and enable the light-emitting unit stop emitting light.
