用以降低液晶显示系统功耗的方法;METHOD FOR REDUCING POWER CONSUMPTION OF A LIQUID CRYSTAL DISPLAY SYSTEM

摘要

用以降低液晶显示系统功耗的方法包含下列步骤：一时序控制器接收一画面的影像讯号；该时序控制器根据该画面的影像讯号，产生一闸极控制讯号与一源极控制讯号；一闸极驱动电路根据该闸极控制讯号，依序驱动复数条扫描线的奇数条扫描线，和再依序驱动该复数条扫描线的偶数条扫描线；一源极驱动电路根据该源极控制讯号、该复数条扫描线的驱动顺序和对应该影像讯号的资料电压，透过复数条资料线对一液晶面板所包含的复数个子像素充电。该复数条资料线上的电压最多被切换一次，且该液晶面板的共同电压为一直流电压。; the timing controller generating a gate control signal and a source control signal according to the image signal; a 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 a plurality of sub-pixels included in a liquid crystal panel through a 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. 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 voltage.
