Claim 4:
5. The touch sensing apparatus of claim 4, wherein the touch sensing circuit calculates delta data, which is a difference between base data and the sensing values of the first-direction electrodes and the sensing values of the second-direction electrodes, substitutes with 0 data of each of a plurality of first-direction sub patterns, close to the first diagonal point and the second diagonal point, in the calculated delta data when the sum of the first touch electrode value and the second touch electrode value is greater than the predetermined threshold value, and identifies the touch coordinates based on the delta data including the data of each of the plurality of first-direction sub patterns close to the first diagonal point and the second diagonal point, which is substituted with 0.
