Abstract: A control device for a capacitive touch panel has multiple voltage driving/current detecting circuits respectively connected to four corners of a top conductive layer of the touch panel. An auxiliary voltage driving/current detecting circuit is connected to a bottom conductive layer of the touch panel. When the touch panel is pressed, all voltage driving/current detecting circuits detect first current values at four corners of the top conductive layer. The auxiliary voltage driving/current detecting circuit also detects a second current value from the bottom conductive layer. The second current value is used to compensate all first current values so that the coordinate information of the position being pressed can be exactly calculated.

Abstract: A scanning control device for a capacitive touch panel uses voltage driving/current detecting circuits to connect to a top conductive layer of the touch panel. Output terminals of all voltage driving/current detecting units are connected to a signal processing unit through a switching unit. Output data of the signal processing unit are output to a central control unit. If the touch panel is pressed, all voltage driving/current detecting circuits detect current values at four corners of the top conductive layer and sequentially output the current values to the signal processing unit. The processed data output from the signal processing unit are transmitted to the central control unit. Based on the received data, the central control unit calculates coordinate of a pressed point on the touch panel.

Abstract: This invention discloses a touch device for distinguishing true touch. The touch device includes a touch screen, a driving unit, and a sensing unit. The touch screen has a plurality of first conductive lines and second conductive lines where the first and second conductive lines are electrically isolated from each other and stacked to form a plurality of coupling intersections. The driving unit operatively drives the first conductive lines. The sensing unit determines the first conductive lines touched or approached by a plurality of objects and also determines the coupling intersections touched or approached by the objects when the first conductive lines touched or approached by the objects are driven. By doing so, the true touch and the false touch caused by the objects can be determined and distinguished.
