Abstract: A source driver apparatus configured to drive a display panel is provided. The source driver apparatus includes a data operation circuit and a pixel driving circuit. The data operation circuit is configured to receive pixel data and perform a polarity determination operation on the pixel data to determine a polarity distribution information of pixels on the display panel. The pixel driving circuit is coupled to the data operation circuit. The pixel driving circuit is configured to drive the display panel according to the pixel data and the polarity distribution information. Furthermore, a driving method of the display panel is also provided.
