Provided is a display panel driving circuit. The display panel driving circuit rearranges and stores image data input of a predetermined number of source lines externally so that data of the same channel neighbor each other, and compares the rearranged data. If the rearranged data are identical, only one buffer is driven, and common data is transferred to a plurality of source lines, outputs the rearranged data according to each channel, sequentially outputs data according to each source line using source drivers of each channel. Thus, when output data neighboring source lines are identical, the current required for the buffer is reduced.
