Abstract
Disclosed is a pixel driving circuit, comprising a driving control circuit, a first driving circuit and a second driving circuit. The driving control circuit is configured to control one of the first driving circuit and the second driving circuit to be turned on under the condition the first scanning line outputs an effective voltage signal, and control the other of the first driving circuit and the second driving circuit to be turned on under the condition the second scanning line outputs an effective voltage signal. The first driving circuit is configured to drive the light emitting circuit to emit light under control of the driving control circuit. The second driving circuit is configured to drive the light emitting circuit to emit light under control of the driving control circuit.
