Abstract
An exemplary embodiment of the present invention provides a stylus pen including: a housing; a conductive tip configured to have at least a portion that is exposed to an exterior of the housing; a resonance circuit disposed in the housing to be connected to the conductive tip and to resonate an electrical signal transferred from the conductive tip; and a conductive blocking member disposed to correspond to a portion of the housing in which the conductive tip is exposed to the exterior.
Claims8
A stylus pen comprising:
- a housing;
- a conductive tip configured to have at least a portion that is exposed to an exterior of the housing;
- a ground portion configured to be electrically connected to a user;
- a resonance circuit comprising an inductor portion and a capacitor portion and disposed in the housing to be connected to the conductive tip and to resonate an electrical signal transferred from the conductive tip;
- a first conductive blocking member disposed between a first area 0.1 mm away from an opening of the housing where the conductive tip is exposed to the outside and a second area 20 mm away from the opening, and electrically connected to the ground portion;
- a second conductive blocking member surrounding at least a portion of the inductor portion and including a plurality of blocking units spaced apart from each other along a first direction in which an eddy current is generated and extending along a second direction perpendicular to the first direction,
- wherein the first conductive blocking member is a single conductive plate and is electrically connected to the ground portion via at least one of the blocking units.
