摘要： A liquid crystal display includes a liquid crystal panel, a drive circuit, and a power circuit. The drive circuit includes a gate driver, a timing control circuit, and a wave signal generation circuit. The timing control circuit sends a timing control signal to the gate driver and the wave signal generation circuit. The wave signal generation circuit generates a control signal according to the timing control signal, and generates a wave signal according to the control signal. The gate driver generates scan signals according to the timing control signal and the wave signal. Before the voltage of the scan signal changes from a maximum voltage to a minimum voltage, the voltage of the scan signal decreases to an invariable middle voltage that is between the minimum voltage and the maximum voltage during a fall time of the scan signal.
