GHOST SUPPRESSION USING HYBRID CAPACITIVE SENSING |
| 摘要 |
A processing system for a capacitive input device includes functionality to perform a trans capacitance measurement of an array of sensor electrodes, determine a presence of at least one input object in the sensing region from the trans capacitance measurement, perform an absolute capacitive measurement along a first axis of the array of sensor electrodes, and suppress the determined presence of at least one input object based on a lack of a correlated input object presence from the absolute capacitive measurement along the first axis. The capacitive input device includes the array of sensor electrodes configured to sense input objects in a sensing region of the input device. |

1. A processing system for a capacitive input device, the capacitive input device comprising an array of sensor electrodes configured to sense input objects in a sensing region of the input device, the processing system comprising functionality to:
perform a trans capacitance measurement of the array of sensor electrodes; determine a presence of at least one input object in the sensing region from the trans capacitance measurement; perform an absolute capacitive measurement along a first axis of the array of sensor electrodes; and suppress the determined presence of at least one input object based on a lack of a correlated input object presence from the absolute capacitive measurement along the first axis. |
