A capacitive touch system uses at least two first integrated circuits to simultaneously scan a touch panel, each of the first integrated circuits only for scanning a portion of the touch panel. Therefore, the capacitive touch system can maintain a good frame rate, even the touch panel is a large scale touch panel. Each of the first integrated circuits transmits its sensed data to a second integrated circuit where a calculation with the received sensed data is executed. The second integrated circuit has at least a common pin connected to each of the first integrated circuits, and therefore the number of pins of the second integrated circuit is reduced.
