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.
