  • Publication number: 20180061340
    Abstract: Embodiments of the disclosure disclose a gate driving circuit, a driving method, and a display device. In the gate driving circuit, the input module transmits the input signal of the input signal terminal to the first node. The reset module resets the first node and the output terminal of the gate driving circuit. The pull-down module pulls down the signal of the first node and the signal of the output terminal of the gate driving circuit to low level signals. The pull-down control module generates a voltage signal of the second node based on the signal of the noise-canceling signal terminal, and controls the pull-down module to pull down a high level noise signal at the first node to a low level signal using the voltage signal. The pull-up module pulls up the signal of the output terminal of the gate driving circuit to a high level signal.
