Abstract

In certain embodiments, a method includes selecting, for a touch sensor including a first number of electrodes and a second number of electrodes, a first set of the first number of electrodes and a second set of the second number of electrodes. The first number of electrodes has a first orientation and the second number of electrodes has a second orientation. The second orientation being different from the first orientation. An overlap area is formed by an overlap of the first set and second set. The method also includes applying, during a first time period, a signal including a first pre-determined voltage to the first set and the second set such that, during the first time period, the overlap area has a first signal state; and applying, during a second time period, the signal to the first set and a second pre-determined voltage to the second set.
