Claim 21:
22. A display device comprising:
a display panel including a plurality of pixels;
a scan driver which provides a scan signal and a sensing signal to a corresponding pixel of the plurality of pixels;
a data driver which provides a data signal to the corresponding pixel of the plurality of pixels;
a sensing circuit coupled to the plurality of pixels through a plurality of sensing lines, the sensing circuit including:
a sensing line initialization circuit which substantially simultaneously initializes the plurality of sensing lines in a first sub-sensing period of a sensing period;
a first line selection switch which couples a first sensing line of the plurality of sensing lines to a sensing channel in the first sub-sensing period;
a second line selection switch which couples a second sensing line of the plurality of sensing lines to the sensing channel in a second sub-sensing period of the sensing period; and
the sensing channel which samples a first sensing voltage of the first sensing line in a first sampling period of the first sub-sensing period, and samples a second sensing voltage of the second sensing line in a second sampling period of the second sub-sensing period; and

a controller which controls the scan driver, the data driver and the sensing circuit,
wherein the second sensing line is not initialized during a period from the first sampling period to the second sampling period, and
the second sampling period is shorter than the first sampling period.
