摘要： A touch sensing apparatus applied to a capacitance touch panel includes a sensing module, a signal generating module, a comparing module, and a processing module. When a first and a second touch point formed on the capacitance touch panel correspond to two first and second touch pad sets, the sensing module generates a request signal. The signal generating module respectively outputs two test signals with reverse phases to the two first touch pad sets according to the request signal. After the comparing module generates a compared result according to two voltage values corresponding to the two second touch pad sets, the processing module will determine the positions of the first and the second touch point according to the compared result. When touch points are more than two, the touch sensing apparatus repeats the above-mentioned steps until all positions of the touch points are defined and the ghost points are removed.

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.
