Method for reducing power consumption of liquid crystal display system

A method for reducing power consumption of a liquid crystal display (LCD) system, wherein the LCD system comprises a liquid crystal panel, a timing controller, a gate driving circuit, a source driving circuit, a plurality of scan lines, and a plurality of data lines, and the liquid crystal panel comprises a plurality of sub pixels, the method comprising the following steps:

• the timing controller receiving an image signal of a frame;
• the timing controller generating a gate control signal and a source control signal corresponding to the gate control signal according to the image signal of the frame;
• the gate driving circuit driving odd scan lines of a plurality of scan lines in turn and then driving even scan lines of the plurality of scan lines in turn according to the gate control signal;
• and
• a source driving circuit charging the plurality of sub pixels through the plurality of data lines according to the source control signal, driving sequence of the plurality of scan lines, and data voltages corresponding to the image signal, wherein voltages of the plurality of data lines are switched one time at most, and a common voltage of the liquid crystal panel is a direct current (DC) voltage.
