Abstract
The embodiments of the present disclosure discloses a gate drive method and a gate drive device of a liquid crystal display, which can avoid the influence by the voltage difference ΔVp between the pixel voltage and the data line voltage, and eliminate the flickering phenomenon and the residual image caused by the residual direct current effectively. The gate drive method of the liquid crystal display comprises: inputting a compensation voltage Vgc to the n-th row of gate line when the n-th row of gate line is turned off completely in the current frame; keep on inputting the compensation voltage Vgc; and stopping inputting the compensation voltage Vgc to the n-th row of gate line when a turn-on voltage Vgh is input to the n-th row of gate line in the next frame; wherein, N≦the total number of the gate lines.
