Abstract

La présente demande concerne un stylet actif. Le stylet actif comprend un mécanisme de pointe de stylet et un élément conducteur qui est disposé autour du mécanisme de pointe de stylet, le mécanisme de pointe de stylet comprenant une recharge conductrice qui est utilisée pour transmettre un signal et un élément d'isolation qui est emmanché à l'extérieur de la recharge conductrice. La recharge conductrice est constituée d'un matériau conducteur souple. L'élément conducteur est utilisé pour recevoir le signal, et l'élément conducteur est emmanché à l'extérieur de l'élément d'isolation, de telle sorte que la recharge conductrice soit isolée de l'élément conducteur. Comme la recharge conductrice n'est pas emmanchée avec un manchon souple et peut ainsi être en contact direct avec un panneau de commande tactile, la performance de transmission de signal de la recharge conductrice est plus forte. De plus, étant donné que la recharge conductrice est constituée d'un matériau conducteur souple, la recharge conductrice ne raye pas le panneau de commande tactile pendant un processus de contact avec le panneau de commande tactile pliable, ce qui permet d'éviter de générer des rayures sur le panneau de commande tactile pliable. La présente demande concerne en outre un système de commande tactile pourvu d'un stylet actif, ainsi qu'un procédé d'interaction d'un système de commande tactile.
