Abstract
A stylus used to have a touch sensitive processing apparatus determine an axial direction and an angle of inclination which the stylus corresponds to a touch screen through electrical signal emitted by the stylus. The stylus includes: a penholder; a tip section on one end of the penholder; a first ring electrode surrounding the penholder; a second ring electrode surrounding the penholder, wherein the second ring electrode is closer to the tip section than the first ring electrode being, the first ring electrode and the second ring electrode are used to emit the electrical signal; and a first insulating material configured to have the first ring electrode electrically decouple the second ring electrode.
Claims15
A stylus used to have a touch sensitive processing apparatus determine an axial direction and an angle of inclination which the stylus corresponds to a touch screen through electrical signal emitted by the stylus, the stylus comprising:
- a penholder;
- a non-conductive tip section on one end of the penholder;
- a first ring electrode surrounding the penholder;
- a second ring electrode surrounding the penholder, wherein the second ring electrode is closer to the tip section than the first ring electrode being, the first ring electrode and the second ring electrode are used to emit the electrical signal, wherein the second ring electrode is in direct contact with the tip section;
- and
- a first insulating material configured to have the first ring electrode electrically decouple the second ring electrode.
