Abstract

A driving circuit includes at least two shift registers in cascade. In each shift register, a first output control module is configured to transmit a voltage of a first voltage terminal to an output terminal in response to a turn-on level of a first node. A second output control module is configured to transmit a voltage of a second voltage terminal to an output terminal in response to a turn-on level of a second node. A first node control module is configured to transmit a voltage of the input terminal to the first node in response to a turn-on level of a first clock signal terminal and transmit a voltage of the second voltage terminal to the first node in response to turn-on levels of the second clock signal terminal and the third node or in response to the turn-on level of the second node.
