Abstract:
1. A method of driving a liquid crystal display (LCD) device, the LCD device comprises a pixel matrix, a timing controller and a gate driver, the method comprising: (a) the timing controller outputting a first Gate-On-Enable signal to the gate driver, when the LCD device displays frame according to a first frame rate; and (b) when the first frame rate is switched to a second frame rate, the timing controller outputting a second Gate-On-Enable signal to the gate driver to cause a charge time of the pixel matrix to be unchanged, wherein a pulse width of the second Gate-On-Enable signal is equal to a summation of a pulse width of the first Gate-On-Enable signal and an adjusted pulse width N(clk), wherein the adjusted pulse width N(clk) is determined by a total number of horizontal pixels, the pulse width OE(clk) of the first Gate-On-Enable signal, and a ratio K of the second frame rate and the first frame rate.
