Abstract
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 to retrieve the sensed data from its responsible traces. Therefore, the capacitive touch system can maintain a good frame rate, even the touch panel is a large scale touch panel. A data transmission method transmits only the non-zero sensed values to a second integrated circuit where a calculation with the non-zero sensed values is executed, and thereby reduces the data transmission time.
