Abstract
A sensing circuit includes a first line selection switch which connects a first sensing line to a sensing channel in a first sub-sensing period, a first noise selection switch which connects the first sensing line to a reference channel in a second sub-sensing period, a second line selection switch which connects a second sensing line to the sensing channel in the second sub-sensing period, and a second noise selection switch which connects the second sensing line to the reference channel in the first sub-sensing period. The sensing channel samples a first sensing voltage and noise of the first sensing line and the reference channel samples noise of the second sensing line in a first sampling period, and the sensing channel samples a second sensing voltage and noise of the second sensing line and the reference channel samples noise of the first sensing line in a second sampling period.
