    Abstract: A touch device includes first and second electrodes intersecting each other, and a touch controller. The touch controller is configured to: apply a first driving signal to the first electrodes; selectively apply a second driving signal to the second electrodes; and detect self capacitances of at least one of the first electrodes and a first portion of the second electrodes intersecting the first electrodes. The at least one of the first electrodes is configured to receive the first driving signal, and the first portion of the second electrodes is configured to receive the second driving signal. The touch controller is further configured to detect mutual capacitances between the at least one of the first electrodes and a second portion of the second electrodes intersecting the first electrodes, in which the second portion of the second electrodes is configured not to receive the second driving signal.
