Abstract: A precharge method for a data driver includes steps of: outputting a display data to a plurality of output terminals of the data driver; outputting a second precharge voltage to an output terminal among the plurality of output terminals prior to outputting the display data to the output terminal, to precharge the output terminal to a voltage level closer to an output voltage; and outputting a first precharge voltage to the output terminal prior to outputting the second precharge voltage. The first precharge voltage provides a faster voltage transition on the output terminal than the second precharge voltage.
