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.
