摘要： Embodiments of the present disclosure provide a pixel driving circuit and a pixel driving method. The pixel driving circuit comprises a driving transistor, a storage capacitor, a light-emitting device, a first switch transistor, a second switch transistor, a third switch transistor, a fourth switch transistor and a fifth switch transistor. The pixel driving circuit and the pixel driving method are implemented such that a driving current generated by the driving transistor is relevant to a working voltage provided by a first power supply terminal, an activation voltage of the light-emitting device, a working voltage of the light-emitting device upon emitting light and a data voltage, yet irrelevant to a threshold voltage of the driving transistor, thereby refraining the driving current flowing through the light-emitting device from influence exerted by the non-uniformity and drifting of the threshold voltage of the driving transistor, and in turn effectively improving the uniformity of the driving current flowing through the light-emitting device. When the activation voltage of the light-emitting device increases with the aging of the light-emitting device, the pixel driving circuit and the pixel driving method enable the driving current flowing through the light-emitting device to increase, thereby compensating for attenuation of the display luminance caused by the aging of the light-emitting device.
