Classification: CPC G | IPC G

Claim 6:
7. The gate drive circuit according to claim 5, further comprising:
a second pull-down node, a second pull-down control sub-circuit, a third noise reduction sub-circuit and a second pull-down sub-circuit, wherein the second pull-down control sub-circuit is coupled to the first voltage signal terminal, a fourth voltage signal terminal, the pull-up node and the second pull-down node;
the second pull-down control sub-circuit is configured to transmit: a fourth voltage signal received at the fourth voltage signal terminal to the second pull-down node in response to the fourth voltage signal received at the fourth voltage signal terminal and the voltage of the first voltage signal transmitted to the pull-up node; and
transmit the first voltage signal received at the first voltage signal terminal to the second pull-down node in response to the fourth voltage signal received at the fourth voltage signal terminal and the voltage of the input signal transmitted to the pull-up node;
the third noise reduction sub-circuit is coupled to the pull-up node, the second pull-down node and the first voltage signal terminal; and
the third noise reduction sub-circuit is configured to transmit the first voltage signal received at the first voltage signal terminal to the pull-up node under control of a voltage of the fourth voltage signal transmitted to the second pull-down node;
the second pull-down sub-circuit is coupled to the signal input terminal, the second pull-down node and the first voltage signal terminal; and
the second pull-down sub-circuit is configured to transmit the first voltage signal received at the first voltage signal terminal to the second pull-down node in response to the input signal received at the signal input terminal, so that the third noise reduction sub-circuit is turned off under control of the voltage of the first voltage signal transmitted to the second pull-down node to stop transmitting the first voltage signal to the pull-up node.
