  • Patent number: 10401995
    Abstract: The present invention provides a touch sensor panel and a fabrication method thereof, in which metal wires for forming a metal mesh are subject to patterning to have symmetrical components being in correlation with each other on the basis of x and y axes, thereby improving visibility. In the touch sensor panel and the fabrication method thereof, the metal wires consist of continuous unit wires in which a unit wire and another unit wire crossing with the unit wire have symmetrical components being in correlation with each other and the size of the symmetrical components is determined based on the line width of the unit wires.
    Type: Grant

  • Patent number: 10379643
    Abstract: The present invention provides an electrode structure for a touch panel and a method for fabricating the same, in which a unit wire and another unit wire continued thereto are continued while the contact area between the unit wires decreases from the entire line width, thereby achieving irregular patterns. In the electrode structure for the touch panel and the method for fabricating the same, a metal wire formed with continuous unit wires has an irregular pattern where the contact area between any one unit wire and another unit wire continued thereto decreases, from the entire line width, by a non-contact size value k obtained by dividing a line width by an arbitrary real number.
