Abstract: A display driving apparatus and a multi-line inversion driving method thereof are provided. The apparatus includes a gate driver, a source driver, a gate enabling unit and a line polarity signal unit. Every time after a plurality of scan lines is turned on, the source driver inverts the polarity of the sub pixel driving signal according to a line polarity signal output by the line polarity signal unit. Thereby, the polarity inversion operating frequency of the sub pixel driving signal is lowered to reduce the power consumption of the source driver.

Abstract: A source driver and an internal data transmission method are provided. The present invention employs specially designed switch units and creates specially designed data paths in a source driver, which matches with the driving method for dot invesion and the specially designed pixel array. When the dot inversion driving method is used on a pixel array of a specific design, each output buffer and digital-to-analog converter inside the source driver continuously output voltages of positive polarity and voltages of negative polarity, instead of switching between positive and negative polarities. Consequently, the swing voltages that the source driver outputs can be lowered, the power consumption can also be reduced accordingly, a smaller area is occupied, and the costs are reduced.
