Abstract
The present disclosure provides a driving circuit, a display device and a driving method, aiming to eliminate influence of potential of output terminal of shift register on potential of control node of the shift register and thus avoid an adverse effect on display. The scan driving circuit includes shift registers. Each shift register includes a first node control unit configured to switch on the input terminal and the first node; a second node control unit configured to switch on the second node and the first clock signal terminal and also to switch on the first power voltage terminal and the second node; a first output unit configured to switch on the second power voltage terminal and the output terminal; and a second output unit configured to switch on the second clock signal terminal and the output terminal. The third node is electrically connected to the first node.
