Abstract:
The present application provides a touch sensitive processing method for a tethered stylus. The method comprises selectively driving two of three circuit components of the stylus in three shorter time periods, sensing induced signals from electrodes of a touch panel, and calculating coordinates of a tip electrode and a surrounding electrode of the stylus accordingly.
