1. A source driver integrated circuit (IC) comprising:
an internal ground GND;
a first switch circuit including a first input terminal electrically connected to the internal ground GND and a first output terminal electrically connected to a sensing line of a display panel, configured to transfer, when turned on in a sensing mode, a sensing reference voltage supplied from the internal ground GND to the sensing line, and configured to be turned off in a display mode;
a driving reference voltage input pad to which a driving reference voltage supplied from an external voltage source is input;
a second switch circuit including a second input terminal electrically connected to the driving reference voltage input pad and a second output terminal electrically connected to the sensing line, configured to transfer, when turned on in the display mode, the driving reference voltage to the sensing line, and configured to be turned off in the sensing mode; and
a sensing channel circuit electrically connected to the internal ground in the sensing mode and configured to receive an electrical characteristic of a pixel included in the display panel through the sensing line.
