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 (a, b) of touch driving signals (TDS) when sensing a touch or a touched position by outputting pulse-type touch driving by which one or more touch electrodes (T...

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