Abstract: A shift register circuit includes a denoising control sub-circuit and a denoising sub-circuit. The denoting control sub-circuit is configured to generate an alternating voltage signal according to a voltage of a first voltage terminal and a signal of a second clock signal terminal in response to a signal of a first clock signal terminal, to rectify the alternating voltage signal and then to output a signal to a first denoising control node, so that the voltage of the first denoting control node is maintained to be a voltage that enables the denoising sub-circuit to be turned on. The denoting sub-circuit is configured to denoise a scan signal output terminal in response to a voltage of the first denoising control node being the voltage that enables the denoising sub-circuit to be turned on.

Abstract: A shift register unit, a driving method, a gate driving circuit and a display device are provided. The shift register unit includes a first gate driving output circuit and a second gate driving output circuit. The first gate driving output circuit is used to output a first gate driving signal through the first gate driving signal output terminal; the second gate driving output circuit is used to generate a second gate driving signal outputted simultaneously with the first gate driving signal based on the first gate driving signal, a first clock signal and a second clock signal. In the present disclosure, the second gate driving output circuit is added, the first gate driving signal, the first clock signal, and the second clock signal are used to generate an inverted second gate driving signal, so that positive and negative switching control signals are generated by one stage of shift register unit.
