Original Abstract Submitted
a sensing circuit of a display device includes a sensing line initialization circuit which substantially simultaneously initializes a first sensing line and a second sensing line in a first sub-sensing period of a sensing period, a first line selection switch which couples the first sensing line to a sensing channel in the first sub-sensing period, a second line selection switch which couples the second sensing line 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. the second sensing line is not initialized during a period from the first sampling period to the second sampling period.
