Summary:A foldable touch sensor panel comprises: a substrate layer; and a division detection part, which is formed on the substrate layer, and is divided more times in a folding area than in a non-folding area and is connected. The division detection part comprises: first detection cells, which are arranged and connected in a folding direction and include a conductive metal having a mesh structure; second detection cells, which are spaced apart from the first detection cells in a horizontal direction, are arranged in the direction of a folding axis, and include a conductive metal having a mesh structure; an insulation layer formed on the first detection cells, the second detection cells, and the substrate layer; and detection cell bridges, which connect the second detection cells in the direction of the folding axis through a through-hole extending through the insulation layer, form an integral contact in areas in contact with the second detection cells by filling an empty space of the mesh structure, and are formed of a transparent conductive material. Panneau à capteurs tactiles pliable comprenant : une couche de substrat ; et une partie de détection de division, qui est formée sur la couche de substrat, est divisée plus de fois dans une zone de pliage que dans une zone de non pliage et est connectée. La partie de détection de division comprend : des premières cellules de détection, qui sont agencées et connectées dans une direction de pliage et comprennent un métal conducteur ayant une structure maillée ; des secondes cellules de détection, qui sont espacées des premières cellules de détection dans une direction horizontale, sont agencées dans la direction d'un axe de pliage et comprennent un métal conducteur ayant une structure maillée ; une couche d'isolation formée sur les premières cellules de détection, les secondes cellules de détection et la couche de substrat ; et des ponts de cellules de détection, qui relient les secondes cellules de détection dans la direction de l'axe de pliage par un trou débouchant s'étendant à travers la couche d'isolation, forment un contact intégral dans des zones en contact avec les secondes cellules de détection par remplissage d'un espace vide de la structure maillée et sont formés d'un matériau conducteur transparent. 폴더블 터치센서 패널은 기재층과 상기 기재층에 형성되고 비폴딩 영역보다 폴딩 영역에서 더 많은 수로 분리되어 연결되는 분할 감지부를 포함하고, 상기 분할 감지부는 폴딩 방향으로 배열 연결되고 메쉬 구조의 도전 금속을 포함하는 제1 감지셀들, 상기 제1 감지셀들과 수평 방향으로 이격되어 폴딩 축의 방향으로 배열되고 메쉬 구조의 도전 금속을 포함하는 제2 감지 셀들, 상기 제1 감지셀들, 제2 감지셀들, 및 기재층에 형성되는 절연층, 및 상기 절연층을 관통하는 관통홀을 통해 상기 제2 감지셀들을 폴딩 축의 방향으로 연결하되 상기 제2 감지셀들과 콘택하는 영역에서 메쉬 구조의 빈 공간을 채워 일체형 콘택을 형성하고, 투명 도전물로 구성되는 감지셀 브릿지들을 포함한다.
