Abstract
A driving method of an LCD panel having a plurality of display groups comprising a plurality of display cells and respectively coupled to a data electrode and a gate electrode. The display cells of the display group are coupled to the data electrode and the gate electrode connected to the display group. The video signals are provided to the data electrodes to make the number of the display groups having the number of the display cells with positive polarity greater than the number of the display cells with negative polarity equal to the number of the display groups having the number of the display cells with negative polarity greater than the number of the display cells with positive polarity. The display groups are coupled to the same gate electrode. Then, the scan signals are provided to the gate electrodes.
