Claim 0:
1. An integrated circuit comprising:
a driving circuit configured to provide a data voltage to a pixel through a data line connected with the pixel of a panel, to sense a voltage of a light emitting diode of the pixel through the data line, and to compare the voltage of the light emitting diode with a reference voltage; and
a detection circuit configured to receive, from the driving circuit, the comparison result between the voltage of the light emitting diode and at least one reference voltage and to determine a defect of the pixel on the basis of the received comparison result,
wherein the driving circuit includes a first driving circuit and a second driving circuit comprising an amplifier, a first switch connected to an output terminal of the amplifier and a second switch connected with the detection circuit at the output terminal of the amplifier, respectively, and
wherein the second switch of the first driving circuit and the second switch of the second driving circuit are connected to each other and to the detection circuit.
