  • Patent number: 8619039
    Abstract: The disclosed translucent or semi-transparent touch screen device includes a mesh composed of a low resistive material and method for forming a touch screen and applying components to the touch screen according to a heat based process. The low resistivity of the mesh beneficially allows pattern traces a small width, and therefore allows more touch zones per specified area than previously available. The disclosed semi-transparent touch screen device may incorporated into a mobile communication device such as a clam shell form factor device with a flip is configured so that an adjacent main display screen is visible through the touch screen device. Input received by the touch screen device is responsive to indicia displayed on the display screen. Since the disclosed touch screen may include many touch zones, beneficially the functionality of the device in the closed position is improved over previous semi-transparent touch screens.
