1. A charge sharing driver circuit for a display, comprising:
an output buffer unit configured to buffer a pair of input signals;
a first output node and a second output node each connected to a display panel;
an output MUX unit configured to electrically connect the first output node and the output buffer unit, and the second output node and the output buffer unit; and
an output switching unit connected between the first output node and the second output node,
wherein a first switching element of the output switching unit is connected between the first output node and a common node, a second switching element of the output switching unit is connected between the common node and a ground, and a third switching element of the output switching unit is connected between the second output node and the common node.
