A touch device includes first electrodes, second electrodes intersecting the first electrodes, and a touch controller configured to apply a first driving signal to first ends of the first electrodes, selectively apply a second driving signal to the second electrodes, detect self capacitances of at least one of the first electrodes and a first portion of the second electrodes intersecting the at least one of the first electrodes, the at least one of the first electrodes configured to receive the first driving signal and the first portion of the second electrodes configured to receive the second driving signal, and detect mutual capacitances between the at least one of the first electrodes and a second portion of the second electrodes intersecting the at least one first electrode, the second portion of the second electrodes configured not to receive the second driving signal.
