    Abstract: A method for making a conductive film exhibiting electric anisotropy comprises forming a nanomaterial on a substrate, the nanomaterial having a cluster of interconnected nanounits, each of which being substantially transverse to the substrate and having one end bonded to the substrate. The method further includes stretching the nanounits along a first direction to remove the nanomaterial from the substrate so as to form a conductive film having strings of interconnected nanounits, where the nanounits of the strings substantially extend in the first direction. A conductive plate and a method for making the same is also disclosed, where the method further comprises attaching the conductive film to a second substrate.

  • Patent number: 8400421
    Abstract: A multi-touch detecting method is adapted for detecting locations of touched points on a touch panel including first and second conductive films, and includes following steps. First measuring points of the first conductive film distributed along X-axis of a Cartesian plane are scanned, and x-components are determined accordingly. Second measuring points of the second conductive film distributed along Y-axis of the Cartesian plane are scanned, and y-components are determined accordingly. A first voltage is applied to the first conductive film, and A second voltage is applied to at least one of the second measuring points with the location on the Y-axis adjacent to or overlapping one of the y-components. Voltages at the first measuring points with the locations on the X-axis adjacent to or overlapping the x-components are measured sequentially and one of the y-components and one of the x-components are outputted.
