  • Patent number: 10437112
    Abstract: A transparent electrode includes a first metal oxide layer, a metal layer and a second metal oxide layer. The first metal oxide layer, the metal layer and the second metal oxide layer are sequentially stacked to form a mesh pattern. A reflectivity at a wavelength of 550 nm of the mesh pattern is in a range from 5% to 20%.

  • Patent number: 10310643
    Abstract: A touch panel includes: an adhesive layer formed on a base film; a protective layer formed on the adhesive layer; a touch sensor portion formed on the protective layer; a bonding pad portion comprising a plurality of unit bonding pads formed on the protective layer as electrically connected to the touch sensor portion; and a first insulating layer formed on the protective layer to extend from a unit bonding pad while filling separation regions between the unit bonding pads. Since the deformations in the elements of the touch panel during the process of bonding the touch panel and the flexible printed circuit board are prevented, there are effects that the degradation in the performance of the touch panel is prevented, and the structural stability of the junction structure of the touch panel and the flexible printed circuit board is secured.
