Claim 6:
7. The sensing circuit of claim 6, wherein the sensing period includes:
the first sub-sensing period in which a first sensing operation for a first pixel coupled to the first sensing line is performed;
the second sub-sensing period in which a second sensing operation for a second pixel coupled to the second sensing line is performed; and
a data output period in which first sensing data corresponding to the first sensing voltage and second sensing data corresponding to the second sensing voltage are output,
wherein the first sub-sensing period includes:
a sensing line initialization period in which the first sensing line and the second sensing line are substantially simultaneously initialized;
a first capacitor initialization period in which the sampling capacitor and the reference capacitor are initialized;
the first sampling period in which the first sensing voltage of the first sensing line is sampled; and
a first analog-to-digital conversion period in which the first sensing voltage is converted into the first sensing data, and

wherein the second sub-sensing period includes:
the second sampling period in which the second sensing voltage of the second sensing line is sampled; and
a second analog-to-digital conversion period in which the second sensing voltage is converted into the second sensing data.
