Abstract:
1. A driving method for a liquid crystal display (LCD) device, the method comprising: determining an inversion type of a driving approach; and performing charge sharing on different groups of data channels according to the different inversion types of driving approaches of the LCD device; wherein at least a group of data channels are coupled to perform charge sharing during at least a partial time of a first inversion type of driving approach of the LCD device, wherein the group of data channels comprise at least a first data channel and a second data channel, and the first and second data channels are not coupled at all during a second inversion type of driving approach of the LCD device, or the first data channel is coupled to one or more third data channels during at least a partial time of the second inversion type of driving approach of the LCD device, wherein at least one of the one or more third data channels is different from the second data channel; wherein the step of performing charge sharing on different groups of data channels according to the different inversion types of driving approaches of the LCD device comprises: turning on the plurality of first charge sharing switches and second charge sharing switches and turns off the plurality of third charge sharing switches, to perform a first charge sharing on the adjacent odd data channels and the adjacent even data channels of the LCD device when the driving approach is a column inversion driving approach.
