  • Touch sensor and fluorescent display having the same
    Patent number: 8842093
    Abstract: An electrostatic capacitance type touch sensor is provided. The touch sensor includes a substrate and a grid pattern formed on a surface of the substrate by a plurality of first linear wires and a plurality of second linear wires, the first linear wires being arranged parallel to each other at a predetermined interval, and the second linear wires being arranged parallel to each other at a predetermined interval and intersecting with the first linear wires. A separation portion is provided to the first linear wires and the second linear wires to form a sensor portion and a dummy sensor portion which are located next to each other and electrically separated from each other.
