Claim 15:
16. The sensing circuit of claim 1, wherein a display panel of the display device includes N odd-numbered sensing lines including the first sensing line and N even-numbered sensing lines including the second sensing line, where N is an integer greater than 0,
wherein the sensing circuit further comprises:
the sensing line initialization circuit which initializes the N odd-numbered sensing lines and the N even-numbered sensing lines;
N sensing channels including the sensing channel;
N first line selection switches which include the first line selection switch, and couple the N odd-numbered sensing lines to the N sensing channels in the first sub-sensing period;
N second line selection switches which include the second line selection switch, and couple the N even-numbered sensing lines to the N sensing channels in the second sub-sensing period;
an analog-to-digital converter; and
a switch matrix which sequentially couples the N sensing channels to the analog-to-digital converter in a first analog-to-digital conversion period of the first sub-sensing period, and sequentially couples the N sensing channels to the analog-to-digital converter in a second analog-to-digital conversion period of the second sub-sensing period, and

wherein the analog-to-digital converter sequentially converts N first sensing voltages of the N odd-numbered sensing lines into N first sensing data in the first analog-to-digital conversion period, and sequentially converts N second sensing voltages of the N even-numbered sensing lines into N second sensing data in the second analog-to-digital conversion period.
