Title
(EN) ACTIVE CAPACITIVE STYLUS AND ELECTRONIC TERMINAL
(FR) STYLET CAPACITIF ACTIF ET TERMINAL ÉLECTRONIQUE
(ZH) 主动式电容笔及电子终端
Abstract
(EN) Some embodiments of the present application provide an active capacitive stylus (100, 200), comprising: a stylus barrel (10); a first electrode (11) disposed at an end of the stylus barrel (10), wherein a distal end of the first electrode (11) located away from the stylus barrel (10) serves as a stylus tip of the active capacitive stylus (100, 200); a second electrode (12) disposed on the stylus barrel (10), and spaced apart from the first electrode (11) in an axial direction of the stylus barrel (10); a third electrode (13) disposed on the stylus barrel (10), and located between the first electrode (11) and the second electrode (12) in the axial direction of the stylus barrel (10); and a switching circuit (14, 24) connected to the second electrode (12) and the third electrode (13), and used to electrically connect the third electrode (13) to the second electrode (12) or to disconnect an electrical connection between the third electrode (13) and the second electrode (12). Another embodiment of the present application provides an electronic terminal having the active capacitive stylus (100, 200).
(FR) Certains modes de réalisation de la présente invention concernent un stylet capacitif actif (100, 200), comprenant : un corps de stylet (10) ; une première électrode (11) disposée à une extrémité du corps de stylet (10), une extrémité distale de la première électrode (11) située à l'opposé du corps de stylet (10) servant de pointe de stylet du stylet capacitif actif (100, 200) ; une deuxième électrode (12) disposée sur le corps de stylet (10), et espacée de la première électrode (11) dans une direction axiale du corps de stylet (10) ; une troisième électrode (13) disposée sur le corps de stylet (10), et située entre la première électrode (11) et la deuxième électrode (12) dans la direction axiale du corps de stylet (10) ; et un circuit de commutation (14, 24) connecté à la deuxième électrode (12) et à la troisième électrode (13), et utilisé pour connecter électriquement la troisième électrode (13) à la deuxième électrode (12) ou pour déconnecter une connexion électrique entre la troisième électrode (13) et la deuxième électrode (12). Un autre mode de réalisation de la présente invention concerne un terminal électronique ayant le stylet capacitif actif (100, 200).
