1. A source driver comprising:
a switch circuit comprising a plurality of first switches, which are respectively connected between a first charge sharing line and a plurality of data lines; and
a charge sharing controller configured to:
receive a plurality of pieces of first pixel data, which respectively correspond to the plurality of data lines, and a plurality of pieces of second pixel data, which respectively correspond to the plurality of pieces of first pixel data;
output a charge sharing signal having an active level to a first group of switches among the plurality of first switches respectively connected to first data lines from among the plurality of data lines, based on the plurality of pieces of first pixel data and the plurality of pieces of second pixel data corresponding to the first data lines being different from each other in at least two upper bits thereof.
