摘要 |
In one embodiment, a method includes substantially simultaneously applying a pre-determined voltage to a conductive layer and to one or more electrodes of a touch sensor. The conductive layer is spatially separated from the electrodes by at least a thickness of a substrate. The method also includes determining a difference between a measurement current of one or more of the electrodes and a reference value; and determining whether a proximity or touch input to the touch sensor has occurred based at least in part on the difference. |

1. A method comprising:
substantially simultaneously applying a pre-determined voltage to a conductive layer and to one or more electrodes of a touch sensor, the conductive layer disposed around at least two sides of a printed-circuit board (PCB), the one or more electrodes situated in a first plane, the conductive layer and the PCB situated in a second plane different than the first plane; determining a difference between a measurement current of one or more of the electrodes and a reference value; and determining whether a proximity or touch input to the touch sensor has occurred based at least in part on the difference. |
