Touch sensing method, touch sensing circuit, and touch display device

A touch sensing method, a touch sensing circuit, and a touch display device perform multifrequency touch driving by varying the frequencies of touch driving signals when sensing a touch or a touched position by outputting pulse-type touch driving by which one or more touch electrodes among a number...

Beschreibung
Zusammenfassung:	A touch sensing method, a touch sensing circuit, and a touch display device perform multifrequency touch driving by varying the frequencies of touch driving signals when sensing a touch or a touched position by outputting pulse-type touch driving by which one or more touch electrodes among a number of touch electrodes disposed on a display panel are driven sequentially. Undesired parasitic capacitance that would otherwise be caused by touch driving signals is prevented from occurring, and EMI influence is reduced.
