1. A display panel, comprising:
a plurality of common electrode blocks; and
a plurality of display regions, wherein during a display period which is neither corresponding to a first display region which is the nearest to a display driver nor corresponding to a second display region which is the farthest from the display driver, one or more common electrode blocks corresponding to one or more of the display regions which are to be displayed during the display period are directly connected to a common voltage; and during the display period, one or more of the common electrode blocks corresponding to one or more of the display regions which are not to be displayed during the display period are kept in a floating state,
wherein during a display period which is corresponding to the first display region, not only a first common electrode block corresponding to the first display region but also a second common electrode block corresponding to the second display region are directly connected to the common voltage, and the common electrode blocks other than the first common electrode block and the second common electrode block are kept in the floating state,
wherein during a display period which is corresponding to the second display region, not only the second common electrode block but also the first common electrode block are directly connected to the common voltage, and the common electrode blocks other than the first common electrode block and the second common electrode block are kept in the floating state.
