A touch sensing apparatus sensing a touch point on a touch panel through an ITO sensor is disclosed. The ITO sensor includes first lines arranged along a first direction and second lines arranged along a second direction. The touch sensing apparatus includes first pins, second pins, a driving/sensing control module, and a data processing module. The first pins are coupled to the first lines, and the second pins are coupled to the lines. At a first time, the driving/sensing control module outputs a driving voltage to the first pins and receives a first sensing signal from the second pins; at a second time, the driving/sensing control module outputs a driving voltage to the second pins and receives a second sensing signal from the first pins. The data processing module computes the first sensing signal and the second sensing signal to generate a touch point sensing result.
