Zusammenfassung:A capacitive touch panel and a ghost point determination method are provided. The capacitive touch panel includes a touch sensing pad and a touch detection module. The touch sensing pad includes a plurality of sensing units. The sensing units are disposed along a first direction and a second direction to from an array. Each capacitance value of the sensing units is decreased gradually along the first direction. The touch detection module is coupled to the touch sensing pad so as to detect at least two real touch points.
