摘要： A touch panel includes a plurality of X-directional sensing lines and a plurality of Y-directional sensing lines. The X-directional sensing lines and the Y-directional sensing lines are arranged in a staggered manner, and a plurality of mutual capacitors are formed between every X-directional sensing line and every Y-directional sensing line. According to one embodiment of the present invention, the scanning method first selects the number of sensing lines to be measured to determine a measurement channel. Driving signals are applied to other sensing lines excluding the measurement channel in scanning procedures. After the driving signals are applied, two voltages at nodes of the measurement channel are detected to obtain a touch position on the touch panel.

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.
