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.
