Abstract
The present invention is directed to a single-axis capacitive multi-touch panel, system and method. A multi-touch panel includes a substrate and some conductive lines formed on one side of the substrate, wherein the conductive lines are arranged in a single axis. A driving circuit, for producing an alternating-current signal, is operatively coupled to the conductive lines of the multi-touch panel, and measuring circuit, for receiving an output signal according to the alternating-current signal to determine touch location, i s operatively coupled to the conductive lines of the multi -touch panel.
