Abstract
A capacitive stylus capable of providing signals for tilt and orientation detection is provided. The capacitive stylus is used for a tablet or a touch panel. The capacitive stylus can emit two high voltage waves, and the tablet or the touch panel receives the two high voltage waves and determines a tilt angle and an orientation of the capacitive stylus according to the two high voltage waves. This capacitive stylus has configuration allowing the tilt and orientation detection to be precise.
