Abstract
A touch panel includes a touch sensing circuit including a plurality of driving electrode lines and a plurality of sensing electrode lines, which intersect the driving electrode lines. The touch panel further includes a driving signal generation circuit that generates a plurality of driving signals and transmits the driving signals to the driving electrode lines, and a sensing circuit that receives a plurality of sensing signals from the sensing electrode lines. The driving signals have voltages that are not equal to zero during a first time zone, and the sum of driving signals generated at the same time is maintained to be equal to zero during the first time zone.
