Abstract: A pixel driving circuit includes a driving signal control sub-circuit and a driving duration control sub-circuit. The driving signal control sub-circuit is configured to provide a driving signal to the driving duration control sub-circuit under control of both a first scanning signal terminal and a enable signal terminal. The driving signal is related to a first data signal received at a first data signal terminal and a first voltage signal received at a first voltage signal terminal. The driving duration control sub-circuit is configured to, under control of the second scanning signal terminal and the enable signal terminal, transmit the driving signal to the element to be driven based on a second data signal with a gradually varying working potential received at the second data signal terminal. The first data signal is different from the second data signal.
