Patent ID: 8810544

Claim:
A touch sensing method, adapted for an electronic apparatus comprising a touch panel, the touch sensing method comprising: obtaining a mutual-mode data by sensing a gesture applied on the touch panel in a mutual capacitance mode during a first period of a sensing frame; obtaining a self-mode data by sensing the gesture applied on the touch panel in a self capacitance mode during a second period of the sensing frame; and after receiving the self-mode data and the mutual-mode data during the sensing frame, determining a touch location associated with the gesture on the touch panel by comparing the self-mode data with the mutual-mode data, determining whether the electronic apparatus is connected to an alternating-current (AC) power supply, wherein if the electronic apparatus is connected to the AC power supply, the touch sensing method further comprising: determining whether the self-mode data and the mutual-mode data are equivalent, wherein if the self-mode data and the mutual-mode data are not equivalent, then determining the touch location associated with the gesture on the touch panel is based on the self-mode data.
