Abstract: An input device described herein includes at least one hybrid electrode that is used to perform both capacitive sensing to detect an input object (e.g., a finger or stylus) and force sensing to determine the force applied by the input object on the input device. During a first time period, the input device drives a modulated signal on one more capacitive sensor electrodes to perform capacitive sensing. However, during a second time period, the input device drives a DC voltage across one or more of the capacitive sensor electrodes to perform force sensing. In one example, during the first time period, the input device drives the modulated signal on transmitter electrodes and measures resulting signals on receiver electrodes. During the second time period, however, the input device may drive the DC voltage across the transmitter or receiver electrodes to measure a force applied by the input object.

Abstract: A capacitive input device processing system includes a transmitter module with transmitter circuitry configured to drive a plurality of transmitter electrodes with transmitter signals. A first receiver module is configured to receive near-field resulting signals from a plurality of near-field receiver electrodes. The near-field resulting signals comprise near-field effects corresponding to the transmitter signals and related to a first portion of a sensing region which is at or near a surface of a capacitive input device. A second receiver module is configured to receive far-field resulting signals from a plurality of far-field receiver electrodes. The far-field resulting signals comprise far-field effects corresponding to the transmitter signals and related to a second portion of the sensing region which extends further from the surface of the capacitive input device than the first portion of the sensing region. The processing system is configured to simultaneously receive the near-field and far-field resulting signals.

Abstract: An input device described herein includes at least one dual purpose electrode that is used to perform both capacitive sensing to detect an input object (e.g., a finger or stylus) and force sensing to determine the force applied by the input object on the input device.

However, during a second time period, the input device excites the first electrode and measures a resistance corresponding to the first electrode. The input device determines a force applied by an input object on the input device based on the measured resistance.
