  • the structure can be applied to any electrode formed by filling the intaglio conductive material.

Abstract

La présente invention concerne une électrode de câblage permettant de réduire une résistance générée dans une ligne de signal et de réduire la survenue d'un fil coupé, un panneau à écran tactile et son procédé de fabrication. L'électrode de câblage pour panneau à écran tactile, selon la présente invention, comprend: une partie contact électriquement connectée à une extrémité d'un motif d'électrode pour générer un signal de contact; une partie connexion entrant en contact avec un circuit d'attaque externe pour transmettre le signal de contact détecté en provenance du motif d'électrode; et une partie lignes de signal qui comprend une pluralité de premières lignes de signal connectées à la partie contact et une pluralité de secondes lignes de signal connectées entre la pluralité de premières lignes de signal et la partie connexion, et qui connecte la partie contact et la partie connexion.
