摘要： A touch sensing apparatus includes a touch screen panel including first electrodes along a first direction and second electrodes along a second direction crossing the first direction to form capacitances with the first electrodes, a driving circuit configured to supply a driving signal to the first electrodes; and a sensing circuit configured to detect output sensing signals from the second electrodes and recognize a touch input based on the output sensing signals. The sensing circuit includes a switching unit configured to modulate the output sensing signals by providing codes as respective input sensing signals to the second electrodes, an amplifying unit configured to amplify the modulated sensing signals, an analog-digital conversion unit configured to convert the amplified sensing signals into digital sensing signals, and a controller configured to demodulate the digital sensing signals and detect a touch input and its position from the demodulated sensing signals.

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.
