The first control sub-circuit is configured to: adjust a voltage of a first node to a turn-on voltage due to an influence of a first direct current voltage signal from a first clock signal terminal, an initial voltage signal from an initial signal terminal and a second direct current voltage signal from a second clock signal terminal; and maintain the voltage of the first node at the turn-on voltage due to an influence of a first clock signal from the first clock signal terminal and a second clock signal from the second clock signal terminal. The first output sub-circuit is configured to be turned on under a control of the turn-on voltage of the first node to transmit a first voltage signal from a first voltage terminal to a signal output terminal.
