1. An integrated circuit comprising:
a pixel sensing circuit configured to sense characteristics of pixels disposed on a panel through a sensing line, wherein the pixel sensing circuit comprises a plurality of channel circuits to be tested for sensing;
a channel selecting circuit configured to generate a channel selection signal for selecting at least one representative channel circuit among the plurality of channel circuits; and
a signal generating circuit configured to supply a test current to a selected representative channel circuit through the sensing line,
wherein, in a test process of the selected representative channel circuit, a connection of the selected representative channel circuit to the signal generating circuit through the corresponding sensing line is activated, and a connection of the selected representative channel circuit to the corresponding pixel through the corresponding sensing line is deactivated, and
wherein, in a pixel sensing process of the pixel, the connection of the selected representative channel circuit to the corresponding pixel through the corresponding sensing line is activated, and the connection of the selected representative channel circuit to the signal generating circuit through the corresponding sensing line is deactivated,
wherein the sensing line is not connected to remaining channel circuits when the sensing line is connected to the representative channel circuit.
