Patents by Inventor Hsing-Ming CHANG

Hsing-Ming CHANG 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).

  • Signal wiring of touch panel
    Patent number: 9007778
    Abstract: A signal wiring of a touch panel mainly extends a bonding portion of a touch sensing unit from a signal wire on a substrate outside the substrate. The bonding portion is further attached to a signal bus so as to shrink the wiring area of the touch sensing unit and the edge frame as well. The bonding portion outside the substrate is allowed to be formed larger for improving improving the stability and yield of the connection between the touch sensing unit and the signal bus.
    Type: Grant

  • Bridging structure for signal transmission of touch panel
    Patent number: 8780067
    Abstract: The invention includes a substrate with a visible area and a shielded area, a touch panel overlapped on the substrate and having touch sensor units overlapping with the visible area and a bridging layer with an insulating film. The touch sensor units are connected with signal wires to electric contacts corresponding to the shielded area. The insulating film cloaks the signal wires and electric contacts. The insulating film is formed with through holes corresponding to the electric contacts and is provided with bridging wires between every two adjacent through holes for connecting all of the electric contacts.
