Abstract:
1. A gate drive method of a liquid crystal display, comprising: inputting a turn-on voltage Vgh to a n-th row of gate line to control the gate line to be turned on; inputting a turn-off voltage Vgl to the n-th row of gate line to control the gate line to be turned off until a timing at which the n-th row of gate line is turned off completely; adding a compensation voltage Vgc to the turn-off voltage Vgl and inputting the added voltage Vgc+Vgl to the n-th row of gate line when the n-th row of gate line is turned off completely in a current frame; keep on inputting the added voltage Vgc+Vgl to cancel out a voltage difference between a pixel voltage of a pixel electrode and a voltage of a data line signal so as to eliminate a flickering phenomenon caused by the voltage difference; and stopping inputting the added voltage Vgc+Vgl to the n-th row of gate line when the turn-on voltage Vgh is input to the n-th row of gate line in a next frame, wherein, n is a positive integer and n≦the total number of the gate lines; the compensation voltage is Vgc=Vgh×Cgs/Cst, Cgs representing a capacitance of a thin film transistor, and Cst representing a capacitance of a storage capacitor.
