Abstract
A drive circuit includes: a first shift register, a first signal line, a second signal line, and a drive module. The first shift register includes a first node and a second node, the first signal line provides a first input signal for the first shift register, the second signal line provides a second input signal for the first shift register, and the first shift register controls potentials of the first node and the second node according to the first input signal and the second input signal. The drive module is electrically connected to the first node, the second node, the first signal line and the second signal line separately, detects the potentials of the first node and the second node, and adjusts at least one of the first input signal and the second input signal according to a potential detection result of the first node and the second node.
