US Patent 11747932 Touch detecting circuit

The present invention relates to a touch detecting circuit, which comprises a touch driving circuit and a touch sensing circuit. The touch driving circuit generates a touch driving signal and provides it to at least one common electrode of a panel. The touch sensing circuit receives a plurality of sensing signals via a plurality of source lines or/and a plurality of gate lines of the panel for detecting the touch location. The sensing signals are generated corresponding to the touch driving signal. In addition, the touch driving circuit may provide the touch driving signal to the source lines. The touch sensing circuit receives the sensing signals via the gate lines for detecting the touch location.
