Pixel driving circuit, pixel driving method, display panel and display device

A pixel driving circuit, comprising a driving signal control sub-circuit, a driving duration control sub-circuit, a first scanning signal terminal, a first data signal terminal, a first voltage signal terminal, an enable signal terminal, a second scanning signal terminal, a second data signal terminal and an element to be driven;

• wherein
• the driving signal control sub-circuit is electrically connected to the first scanning signal terminal, the first data signal terminal, the first voltage signal terminal, the enable signal terminal and the driving duration control sub-circuit, and is configured to provide a driving signal to the driving duration control sub-circuit under control of a first scanning signal transmitted via the first scanning signal terminal and an enable signal transmitted via the enable signal terminal;
• and the driving signal is related to a first data signal received at the first data signal terminal and a first voltage signal received at the first voltage signal terminal;
• and
• the driving duration control sub-circuit is electrically connected to the second scanning signal terminal, the second data signal terminal, the enable signal terminal and the element to be driven, and is configured to transmit the driving signal to the element to be driven under control of a second scanning signal transmitted via the second scanning signal terminal and the enable signal transmitted via the enable signal terminal;
• and a duration for transmitting the driving signal to the element to be driven is related to a second data signal received at the second data signal terminal.
