Capacitive touch system and control method for a capacitive touch system
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...

| Zusammenfassung: | 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. |
