Abstract: A dual-mode touch sensing method adapted for a stylus and a touch panel comprising N first signal lines and M second signal lines. The method comprises: sequentially controlling the N first signal lines to emit N corresponding pulse signals in N gesture periods in a scanning period, receiving M gesture feedback signals corresponding to the pulse signals via the M second signal lines in each among the N gesture periods, selectively generating a gesture signal based on the gesture feedback signals, determining a stylus period other than the N gesture periods in the scanning period by the stylus, generating a stylus signal in the stylus period by the stylus, and receiving the stylus signal and generating a stylus touching signal accordingly by the touch panel.

Abstract: A circuit for touch sensing includes a driving unit, a self-capacitive sensor circuit, a mutual-capacitive sensor circuit and a control circuit. The driving is configured to generate a driving signal. The self-capacitive sensor circuit is configured to generate a self-capacitance sensing result. The mutual-capacitive sensor circuit is configured to receive the driving signal in order to generate a mutual-capacitance sensing result when the voltage of a node between the self-capacitive sensor circuit and the mutual-capacitive sensor circuit reaches a reference voltage. The control circuit receives and computes the self-capacitance sensing result and the mutual-capacitance sensing result in order to generate a sensing result. By utilizing the circuit for touch sensing of present disclosure, the accuracy and the efficiency of touch sensing can be enhanced.

Abstract: A capacitive touch device and a sensing method thereof are disclosed. The capacitive touch device includes a touch panel and a plurality of touch detection units. The touch panel includes first sensing lines and second sensing lines. The position of a touch between a last one of the first sensing lines and a first one of the second sensing lines is calculated according to sensed values respectively corresponding to a first sensing line prior to the last one of the first sensing lines, the last one of the first sensing lines and the first one of the second sensing lines. The present invention is capable of avoiding the problem that the frame rate is reduced significantly because of the data transmission between the first and second touch detection units.
