Liquid crystal display device and driving method thereof with varying line row inversions

A driving method of a liquid crystal display (LCD) device, the liquid crystal display device comprising a liquid crystal display panel comprising multiple data lines, multiple gate lines intersected with the data lines, and a common electrode, wherein the driving method comprises:

• sending gate-scanning signals to the gate lines, each gate-scanning signal comprising a period corresponding to one frame and substantially equal to a time interval to scan one gate line;
• sending a common voltage to the common electrode;
• and
• sending multiple voltage levels of a gray level voltage signal respectively to the data lines during the time the liquid crystal display panel is scanned by the gate-scanning signals;
• wherein the common voltage comprises at least three square waves having three non-identical periods, each square wave corresponds to a frame period and has a substantially constant period, and the at least three square waves comprise a first square wave having a first period which is twice the period of each gate-scanning signal, a second square wave having a second period which is four times to the period of each gate-scanning signal, and a third square wave having a third period which is six times to the period of each gate-scanning signal.
