Abstract
A control buffer in a source driver includes a first CMOS inverter configured to output a switch signal to control turning on and off of a switch, and a first tri-state inverter that is connected to the first CMOS inverter and configured to selectively adjust a size of the control buffer, wherein a slew rate of the switch signal is adjusted depending on the size of the control buffer.
