The invention is not limited to the above Example. - As mentioned above, each drive channel is responsible for 1 drive voltage of the same polarity during different scan periods. For example, the driving channel (3) 2 outputs the positive driving dust Vp2 during the first sweep and the positive driving voltage Vpi during the second scanning. Since the voltage swing between the driving voltages t of the same polarity is small', the power consumption of the source driver 2 2 G can be reduced and the temperature of the display device 200 can be lowered. , Zhuangsi's is 'in the N-cell elements 231 on each scan line, 'the mother two consecutive elementary units are regarded as a single element, which corresponds to ,), green (G), blue (9) 'That is, a multiple of 3. Therefore, during the first-scan period, every three consecutive continuations of the vine movement channel to the Qing: the regional movement should be respectively (four) should be the driving voltage of red, green and blue. Each of the three consecutive drive channels in the "Scanning Period" drive channel CH2J_CHN+1 should respectively output drive voltages corresponding to red, green, and blue. As the size of the slab increases, the single-source drive (four) drive channel The number may be used later. Therefore, the designer must use a secret driver to drive the k display panel. The following implementation side is as described above, providing a related device using multiple sources and driving (4) to drive the high-resolution display panel. The present invention is generally known to those skilled in the art. Fig. 3B is a schematic diagram of a display device according to an embodiment of the invention.
