PROJECTIVE CAPACITIVE STYLUS AND CONTROLLING METHOD THEREOF

摘要

Configurations of a stylus and controlling methods thereof are disclosed. The proposed stylus causes a touch panel to generate a signal by an electrical field generated by a magnetic field via one of a conductor and an electric plate, wherein the stylus includes a set of windings and a magnet, which can move towards each other and generate a current on the set of windings through interaction. The current flows through the conductor/electric plate on a tip of the stylus to generate one of an electric flux line and a magnetic flux line such that the touch panel can sense the movement of the stylus.

主权项

1. A projective capacitive stylus, comprising:
a magnet having a first terminal and a second terminal; a winding allowing an entrance and an exit of the first terminal of the magnet, wherein when an external force causes the magnet and the winding to generate a first relative motion, a first current is generated on the winding; a spring connected to the second terminal of the magnet, wherein when the external force is removed, the spring causes the magnet and the winding to generate a second relative motion and causes a second current to be generated on the winding; and one of a conductor and an electric plate, configured on a tip of the stylus and electrically connected to the winding, wherein the projective capacitive stylus is free from a tuning circuit and a built-in power supply, and when the first current and the second current are respectively generated, a first signal and a second signal are correspondingly generated on an external touch panel via the one of the conductor and the electric plate.
