Abstract
A pixel driving circuit, a driving method and a display device are provided. The pixel driving circuit includes a driving unit, a capacitor unit, a data write-in unit connected to a corresponding gate line, a corresponding data line and the driving unit, a power source control unit connected to a first light-emitting control end, a 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 not to emit light.
