  • Patent number: 11620022
    Abstract: The disclosure provides a floating touch display device which includes a capacitive touch panel, a display device, an interval layer, and an optical-lens structure. The capacitive touch panel is configured to provide a floating touch surface at a floating height above a first surface. The display device includes a second surface, and the display device is configured to provide a display image from the second surface. The optical-lens structure is disposed between the capacitive touch panel and the display device. The interval layer is disposed between the second surface and the optical-lens structure, and a first optical distance is between the second surface and the optical-lens structure. The optical-lens structure is configured to image the display image on the floating touch surface at a second optical distance, and the first optical distance is equal to the second optical distance.

  • Publication number: 20220357813
    Abstract: A touch sensor having a visible area and a peripheral area at least on one side of the visible area includes a substrate, a touch electrode layer, and peripheral traces. The touch electrode layer is disposed on a surface of the substrate and includes touch electrodes corresponding to the visible area. The peripheral traces are disposed on the surface of the substrate and corresponding to the peripheral area. The peripheral traces are respectively electrically connected to the touch electrodes. Each of the peripheral traces includes a matrix and metal nanowires distributed in the matrix. A line width of each of the peripheral traces is more than or equal to 6 ?m and less than or equal to 12 ?m, and a line spacing of any adjacent peripheral traces of the peripheral traces is more than or equal to 6 ?m and less than or equal to 12 ?m.

  • Publication number: 20220301739
    Abstract: An optically consistent transparent conductor includes a first region and a second region. The first region includes a plurality of nanostructures. The first region has a first electrical resistivity and a first haze. The second region has a second electrical resistivity and a second haze. A difference in ratio between the first electrical resistivity and the second electrical resistivity is in a range from 5% to 9900%, and a difference in ratio between the first haze and the second haze is in a range from 2% to 500%.
