A method for driving a display device is disclosed. Display images of one frame are divided into detection regions; pixel polarity arrangements of each detection region are determined, and according to the determined result a data driving circuit selects a corresponding scanning method to drive the display device. The data driving circuit adopts an interlaced-to-progress scanning conversion method to drive the display device, so as to ensure that there are no data circuits in a loaded state, thereby reducing the power consumption of the display device.
