Abstract:
The pixel driving circuit includes a current control sub-circuit configured to output a gray scale current signal to an element to be driven, and a gating sub-circuit. The gating sub-circuit is coupled to a scan signal terminal, a reset signal terminal, a gating data signal terminal and a pulse voltage signal terminal; the gating sub-circuit is configured to drive the element to be driven to continuously emit light under the control of a scan signal from the scan signal terminal and a gating data signal from the gating data signal terminal, and to drive the element to be driven to intermittently emit light under the control of a reset signal from the reset signal terminal, the gating data signal from the gating data signal terminal, and a pulse voltage signal from the pulse voltage signal terminal.
