A source driver having the charge recycling function is suitable for a panel displaying device to drive a display array unit. The source driver includes a source driving circuit to output a plurality of data signals corresponding to a plurality of data lines. A circuit for recycling charges is coupled between the source driving circuit and the display array unit, including a plurality of switches to form a path of recycling charges and to transmit the data signals for driving the display array unit. A switch control circuit generates a set of control signals according to a timing relationship of the data signals of the circuit of source driving, to timely control the on/off states of each switch of the circuit for recycling charges. Consequently, a part of charges on the data lines can be recycled during a period of charging and discharging for the next period.
