Abstract:
A conductive multi-touch touch-sensitive panel includes two intersecting but electrically isolated arrays of linear conductors which can be brought into electrical contact by touching the panel. A display element may be positioned beneath the two arrays of linear conductors to provide a touchscreen panel. A touch to a cover plate or member causes one or more linear conductors in one array to contact one or more linear conductors in the other array. The location of a touch to the panel can be detected by individually or sequentially applying an electrical signal, such as a voltage or current, to each linear conductor in one array while sensing voltage or current on each of the linear conductors in the other array.
