    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 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 transmit the driving signal to the element to be driven under control of a second scanning signal terminal and a enable signal terminal. A duration for which the driving signal is transmitted to the element to be driven is related to a second data signal received at a second data signal terminal.

    Abstract: Disclosed is an array substrate including multiple first selection circuits with each including at least two first selection transistors and at least two first anticreeping transistors. Each first selection transistor is connected with one first anticreeping transistor in series. When the first selection transistor is turned on by a first turn-on signal from a first control signal terminal, the first anticreeping transistor is turned on by a second turn-on signal from a second control signal terminal. When the first selection transistor is turned off by a first turn-off signal from the first control signal terminal, the first anticreeping transistor is turned off to make the first selection transistors and the data signal terminal disconnected, by a second turn-off signal from the second control signal terminal. A voltage of the first turn-off signal is greater than a voltage of the second turn-off signal.
