Abstract:
A display driving device and a method for driving a display panel are provided. The display driving device includes the display panel and a display driver. The display panel includes a plurality of pixel units and a plurality of multiplexers. Each of the multiplexers is disposed with N data lines. The display driver provides a plurality of display data strings and a plurality of selection signals to the multiplexers to control the multiplexers according to the selection signals to receive and sequentially output the display data of the pixel units. Each of the display data strings forms two display data sets of different polarities in a same scan line, and the display data sets include the display data of at least one pixel unit. Thereby, the polarity inversion number of the display data and accordingly the power consumption can be reduced when the display driving device drives the pixel units.
