Abstract
A touch sensing system comprises: a touch sensing unit which includes regions having predetermined coordinates; and a baseline updating unit for updating a baseline by reflecting sensing signals outputted from the touch sensing unit. The baseline updating unit includes a comparator for calculating difference values between the sensing signal of an n-th frame and the baseline of an n−1-th frame for each region, and for comparing the difference values with predetermined reference values. The touch sensing system further comprises an arithmetic unit for setting the baseline of the n−1-th frame as the baseline of the n-th frame for a region in which the difference values are larger than the reference values and for the region adjacent to it, and for updating the baseline of the n-th frame by a predetermined arithmetic for a remaining region.
