為了減少TFT-LCD驅動器的功率消耗，我們利用LCD寄生電容來實現電荷再使用的技術，進而提出不須外掛電容的多相電荷回收技術，根據這個方法，電壓振幅將可以減少為原始電路之電壓振幅的(1/2n + 1/4)，其中 ”n”是代表每一個群組的資料線數目。如果”n”越大，電壓振幅將會愈小，進而達到低功率消耗的目的。比較原始電路(即不採用任何電荷回收技術)與一般傳統的電荷分享技術，我們所提出的方法可以節省更多的功率消耗。以八條資料線為一組的電路來看，我們的方法可以比原始電路節省更多功率，符合低功率消耗驅動電路的目的。

To reduce the power consumption of the TFT-LCD column driver，a novel multi-phase charge-recycling technique that doesn’t require any external capacitor for charge conservation is proposed. Based on this method, the voltage swing is reduced to (1/2n + 1/4)VSWING, where “n” is the number of data lines in one group. If n is larger, voltage swing will become smaller in order to achieve lower power consumption goal. Comparing with original circuit (without any charge-recycling) and charge sharing one, the proposed method can reduce the power consumption about 65.7% ~ 13.3% respectively for n=8.
