  • Publication number: 20190391679
    Abstract: A metal mesh touch electrode for a touch panel comprises a plurality of breakpoint regions, a plurality of first metal mesh electrodes and a plurality of second metal mesh electrodes. The breakpoint regions are disposed between the first and second metal mesh electrodes. The first metal mesh electrodes comprises a first metal mesh layout formed by a plurality of first metal lines and a plurality of second metal lines that mutually intersect. The second metal mesh electrodes include a second metal mesh layout formed by the plurality of first metal lines and the plurality of second metal lines that mutually intersect. The plurality of first metal lines and the plurality of second metal lines intersect to form a plurality of intersections creating a mesh spacing. Widths of the first and second metal mesh electrodes and the breakpoint region comprise a sensing spacing.

  • Patent number: 10330968
    Abstract: A touch sensing structure includes a substrate, a first electrical conductive electrode, a second electrical conductive electrode, an insulating layer and a bridge electrode. The first electrical conductive electrode includes a plurality of first regions covering the surface of the substrate and the first regions are interconnected by a connection electrode. The second electrical conductive electrode includes a plurality of second regions covering the surface of the substrate. The insulating layer covers the first and second electrical conductive electrodes and the connection electrode. The bridge electrode goes beyond the connection electrode to connect immediately-adjacent two of the second regions, and the bridge electrode pass through two through holes of the insulating layer to connect immediately-adjacent two of the second regions.

  • Patent number: 10042448
    Abstract: A touch module for preventing separation of silver paste between laser etching traces, comprises a substrate, a plurality of touch electrodes, and a silver paste. A side of the touch electrode has a pin area. The pin area contains a plurality of perforations. The silver paste is coated on the substrate and the pin area for connecting electrical circuitry between the pin area and the connection line area. Wherein the silver paste on the pin area flows into the perforations and connects to the substrate. Therefore separation of the silver paste on the pin area and touch electrodes will less likely occur due to minor coating errors. The present invention also provides a manufacturing method of a touch module that prevents separation of the silver paste between laser etching traces.
