IPC: G06F3/044

Abstract: A touch sensor including a sensor array including a first touch node and a second touch node adjacent to each other in at least one of a first direction or a second direction, the second direction perpendicular to the first direction, the first touch node and the second touch node electrically separated from each other, each of the first touch node and the second touch node including a driving electrode and a sensing electrode, and a controller configured to output a first driving signal having a first phase to the driving electrode of the first touch node and output a second driving signal having a second phase opposite to the first phase of the first driving signal to the driving electrode of the second touch node may be provided. The controller may be further configured to output the first driving signal and the second driving signal simultaneously.
