Abstract:
A stylus adapted to a touch panel is provided. The stylus comprises a barrel, a driving circuit disposed inside the barrel and configured to generate a driving signal, a conductive tip disposed at an end of the barrel and electrically connected to the driving circuit to receive the driving signal, and a conductive grip disposed at the barrel and electrically isolated from the conductive tip. The conductive tip is capacitively coupled with the touch panel via the driving signal to form a first induced capacitor on the touch panel. A capacitance effect is generated between the conductive grip and the touch panel to form a second induced capacitor on the touch panel. A touch control method is also provided.
