Claim 5:
6. The display device of claim 5, wherein the sensing driver further comprises:
a sensing line controller which controls a connection between the at least two sensing lines of the corresponding sensing lines and the analog front end, to sense a first pixel group of the plurality of pixels in the previous sensing period and sense a second pixel group of the plurality of pixels in the current sensing period;
an analog-digital converter which outputs digital real sensing values of a plurality of second pixels included in the second pixel group, based on a signal provided from the analog front end in the current sensing period;
an interpolator which calculates preliminary sensing values of a plurality of first pixels which are included in the first pixel group and not sensed in the current sensing period by interpolating the real sensing values of the second pixel group;
a difference calculator which calculates a sensing value difference as the difference between the previous sensing value of the target pixel sensed in the previous sensing period and the preliminary sensing value of the target pixel; and
a sensing value determiner which determines the final sensing value of the target pixel by comparing the sensing value difference with a predetermined reference value.
