摘要： 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.

摘要： A touch panel includes a first touch electrode disposed on a base substrate and a second touch electrode disposed on an insulating layer, which is disposed over the first touch electrode. The first touch electrode includes a first linear pattern disposed along a first direction and a first protrusion pattern extending from the first linear pattern. The second touch electrode includes a second linear pattern disposed along a second direction crossing the first direction and a second protrusion pattern extending from the second linear pattern. Wires connect the first touch electrode and the second touch electrode to a driving circuit. The second protrusion pattern partially overlaps the first protrusion pattern.
