TOUCH SCREEN POWER-SAVING SCREEN SCANNING ALGORITHM |
摘要 |
A method for detecting touch locations on a capacitive array includes the steps of scanning for at least one touch location on an entire capacitive array using a first sensing circuitry and detecting the at least one touch location with the first sensing circuitry. A smaller portion of the capacitive array is determined responsive to the detection of the at least one touch location. The at least one touch location is scanned only within smaller portion of the capacitive array using a second sensing circuitry. The at least one touch location is detected with the second sensing circuitry and output for use. |
