Abstract: A source driver includes an output unit and a pre-charge unit. The output unit includes a first output amplifier to output a first output voltage and a second output amplifier to output a second output voltage. A polarity of the second output voltage is opposite to a polarity of the first output voltage. The pre-charge unit pre-charges an input of the first output amplifier and an input of the second output amplifier during a first period, upon a polarity change of the output unit.
