Abstract: The LCD device comprises a plurality of scan groups and a plurality of data electrodes; each scan group comprises a plurality of scan electrodes. The driving method comprises the following steps. First the scan driving circuit provides a plurality of scan signals to the plurality of scan electrodes of the plurality of scan groups, respectively. Each scan signal includes at least a select signal, at least a non-select signal, at least a select cycle, and at least a non-select cycle. The select signal is located in the select cycle, while the non-select signal, the non-select cycle. When an Nth scan electrode is located in the select cycle, an (N−1)th or (N+1)th scan electrode of the plurality of scan electrodes is located in the non-select cycle. Then, the data driving circuit provides a data signal to each of the data electrodes according to a plurality of display data for driving the LCD device to display an image by using the plurality of scan signals and the plurality of data signals. Thereby, the imbalance wire coupling effect among scan electrodes can be eliminated and thus improving the display efficiency of the LCD device.

Abstract translation: LCD装置包括多个扫描组和多个数据电极; 每个扫描组包括多个扫描电极。 驱动方法包括以下步骤。 首先，扫描驱动电路分别向多个扫描组的多个扫描电极提供多个扫描信号。 每个扫描信号至少包括一个选择信号，至少一个非选择信号，至少一个选择周期和至少一个非选择周期。 选择信号位于选择周期，而非选择信号，非选择周期。 当第N扫描电极位于选择周期中时，多个扫描电极中的第（N-1）或（N + 1）扫描电极位于非选择周期中。 然后，数据驱动电路根据用于驱动LCD装置的多个显示数据向每个数据电极提供数据信号，以通过使用多个扫描信号和多个数据信号来显示图像。 由此，可以消除扫描电极之间的不平衡线耦合效应，从而提高LCD器件的显示效率。
