Claim 22:
23. A method of operating a sensing circuit of a display device, the method comprising:
substantially simultaneously initializing a first sensing line and a second sensing line in a first sub-sensing period of a sensing period;
coupling the first sensing line to a sensing channel in the first sub-sensing period;
sampling a first sensing voltage of the first sensing line by the sensing channel in a first sampling period of the first sub-sensing period;
coupling the second sensing line to the sensing channel in a second sub-sensing period of the sensing period; and
sampling a second sensing voltage of the second sensing line by the sensing channel in a second sampling period of the second sub-sensing period,
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.
