Abstract
The present disclosure discloses a gate driving circuit including multi-stage shift registers, and an output side switch element which is controlled by the second clock signal to be turned on or off. The output side switch element is located between an input terminal and an output terminal of each stage shift register. An output terminal of the (N+2)-th stage shift register is coupled to a reset terminal of the N-th stage shift register.
Claims20
A gate driving circuit comprising multi-stage shift registers, and each stage shift register of the multi-stage shift registers is coupled with both of a first clock signal line and a second clock signal line;
- wherein, for any integer N which is not less than 2, an input terminal of an N-th stage shift register is coupled with an output terminal of an (N−1)-th stage shift register;
- an output terminal of the N-th stage shift register is coupled with an input terminal of an (N+1)-th stage shift register;
- a reset terminal of the N-th stage shift register is coupled with an output terminal of an (N+2)-th stage shift register;
- the gate driving circuit further comprises an output side switch element disposed between the input terminal and the output terminal of the N-th stage shift register;
- the output terminal of the N-th stage shift register is coupled with a second terminal of the output side switch element;
- a first terminal of the output side switch element is coupled with the input terminal of the N-th stage shift register;
- a control terminal of the output side switch element is coupled with the second clock signal line.
