Abstract

An electronic stylus to be used with a capacitive touch screen includes a tip portion having an electrically conductive tip and an electrically conductive supporting rod attached to the tip. The tip portion further includes a first electrical shielding tube enclosing and shielding the supporting rod and a second electrical shielding tube enclosing the first electrical shielding tube and the supporting rod. The electrical stylus further includes a circuit coupled to the supporting rod to integrate and amplify a current induced at the tip and an electrical conductive housing to house the circuit therein. The first electrical shielding tube and the second electrical shielding tube are to reduce skew effect between the supporting rod and a surface of a touch screen when the electronic stylus is held against the surface of the touch screen.
