Patents by Inventor Eung Goo CHO

Eung Goo CHO has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11314359
    Abstract: A touch sensing electrode structure includes sensing electrodes, each of which including a plurality of unit patterns, and traces electrically connected to the sensing electrodes. The traces include at least two trace lines and trace bridges connecting the at least two trace lines to each other. An electrode visibility due to a pattern deviation is reduced and a reliability of the trace is improved by the trace bridge.
    Type: Grant

  • 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: 10338758
    Abstract: A touch sensing electrode structure includes an electrode line and connecting electrodes. The electrode line extends in a first direction as a zigzag line shape, and a plurality of the electrode lines are arranged along a second direction that crosses the first direction. The connecting electrodes extend in the second direction and connect neighboring ones of the electrode lines to form a plurality of concave polygonal patterns.
