LIQUID CRYSTAL DISPLAY POWER SAVING METHOD

A liquid crystal display power saving method is disclosed. It includes steps of: (a) dividing output channels coupled to a panel into multiple sets and each set includes M output channels, M is a positive integer; (b) calculating an average of the (N-1)-th display line of the panel after charge sharing, N is a positive integer larger than 1; (c) determining whether each of M output channels consumes power when it transmits a data signal from the (N-1)-th display line to the N-th display line; (d) calculating total power consumption of transmitting the data signal from the (N-1)-th display lineto the N-th display line under possible charge sharing methods among the M output channels; (e) selecting a lowest power consumption charge sharing method from the possible charge sharing methods; and (f) switching coupling relationships among the M output channels according to the lowest power consumption charge sharing method. 种液晶显示器省电方法，包含下列步骤：(a)将耦接显示面板的多个输出通道分为多组输出通道且每组输出通道包含M个输出通道，M为正整数；(b)计算显示面板的第(N-1)条显示线的电荷分享后的平
