Claim Text:
1. A power saving method for a liquid crystal display (LCD), the LCD comprising a plurality of scan lines, the power saving method comprising: segregating the scan lines into a plurality of scan-line groups comprising a first scan-line group and a second scan-line group; and individually performing a waveform-shaping function on each of the scan-line groups at different time points by a plurality of waveform-shaping circuits each coupled to one of the scan-line groups, wherein the waveform-shaping circuits comprise a first waveform-shaping circuit corresponding to the first scan-line group and a second waveform-shaping circuit corresponding to the second scan-line group, the waveform-shaping function performed on the first scan-line group is being disabled by the first waveform-shaping circuit according to a second timing control signal, and the waveform-shaping function performed on the second scan-line group is being enabled by the second waveform-shaping circuit according to a first timing control signal; wherein the second timing control signal according to which the waveform-shaping function of the first scan-line group is disabled is transmitted from the first waveform-shaping circuit to the second waveform-shaping circuit to serve as the first timing control signal according to which the waveform-shaping function of the second scan-line group is enabled.
