Power reduction of a capacitive touch system |
摘要 |
A capacitive touch system uses at least two integrated circuits to simultaneously scan a touch panel, each of the integrated circuits scanning only a portion of the touch panel. If any one of the integrated circuits has not detected any objects on its scanning zone for a long time, it will enter a suspend mode to lower the scanning frequency thereof for power saving.
