摘要： A capacitive touch system uses at least two touch integrated circuits to simultaneously scan a touch panel, each of the touch integrated circuits only for scanning a portion of the traces 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. Sensing methods are provided to determine a sensed value for a boundary trace which is the last one of the traces connected to a first touch integrated circuit and prior to the first one of the traces connected to a second touch integrated circuit.

摘要： A capacitive touch system uses two or more integrated circuits to simultaneously scan a touch panel in such a manner that each of the integrated circuits scans only a portion of the touch panel to retrieve a respective detected data by itself. All the detected data are used for computation by one of the integrated circuits or one other than the integrated circuits to determine a touch information. This approach enables axis intersect projected capacitance touch integrated circuits applicable to a large scale touch panel, without degrading the frame rate of a capacitive touch system.

摘要： A capacitive touch system uses at least two integrated circuits to simultaneously scan a touch panel, each scanning only a portion of traces of the touch panel, and a second integrated circuit to receive sensed data from the first integrated circuits. The sensed data contains parameters representing a sum of the sensed values of all traces in a direction that one of the first integrated circuits is in charge of scanning, a sum of products obtained by multiplying the sensed value of each trace in the direction that the one of the first integrated circuits scans by the order number of that trace, a number of fingers in the direction detected by the one of the first integrated circuits, and whether or not the sensed values of the first and last traces in the direction that the one of the first integrated circuits scans are zero.

摘要： A scan method for a touch panel has steps of: receiving a self-sensing frame; calculating sensing slopes between each sensing line and its neighboring sensing lines in the self-sensing frame; determining whether any sensing slope is larger than a slope threshold, and marking the sensing line if the sensing slope is larger than the slope threshold; and executing a mutual scan approach on the marked sensing lines to produce a mutual sensing frame without sensing point caused by noise. Further, the present invention also increases the frame rate since only a part of sensing lines need to be scanned.

摘要： 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.
