摘要： A touch input device for switching driving signals includes a touch panel and a panel driving circuit for driving the touch panel. The panel driving circuit includes a selecting circuit, a driving signal generating circuit, and a touch sensing circuit. The driving signal generating circuit transmits a driving signal to the touch panel. The selecting circuit includes a multiplexer, which controls sensing lines that do not comprise either an X directional measuring channel or a Y directional measuring channel to be grounded or floating in accordance with the driving signal.

摘要： A control device of an ungrounded touch-sensing panel is disclosed. The touch-sensing panel includes a plurality of first-directional lines and a plurality of second-directional lines arranged intersecting one another. The control device includes a selection circuit, at least one capacitor, a driving signal generation circuit, an analog to digital conversion module and a signal processing unit. The selection circuit is configured to select at least one scan line and at least one sense line from the first-directional lines and the second-directional lines during each scanning operation. After the new scan line and sense line are generated, each capacitor is coupled between each scan line and each sense line selected by the selection circuit to increase a total capacitance between the scan line and the sense line.
