Abstract: An example input device for force and proximity sensing includes a plurality of touch electrodes comprising touch transmitter electrodes and touch receiver electrodes, a force electrode layer comprising a plurality of force electrodes, and a processing system. When operating in a proximity sensing mode, the processing system drives the touch transmitter electrodes with touch transmitter signals and determines a position of an input object, within a sensing region defined by the plurality of touch electrodes, based at least in part on a transcapacitive proximity measurement acquired from the touch receiver electrodes. When operating in a force sensing mode, the processing system drives the plurality of force electrodes with force transmitter signals and determines a force of the input object based at least in part on a transcapacitive force measurement based on a change in capacitance between the plurality of force electrodes and the plurality of touch electrodes.

Abstract: Embodiments of the invention generate a voltage gradient across a sensor electrode by driving a negative and positive voltage on respective ends of the electrode to identify a location of an input object. Because both negative and positive voltages are used, one location on the sensor electrode will be at a reference voltage (e.g., system ground). This location is used to divide the sensor electrode into two different regions. Based on measuring a change in charge relative to a baseline, the input device identifies in which of the two regions the input object is located. The input device can then generate a new voltage gradient to shift the location of the reference voltage into the identified region thereby dividing the region into two sub-regions. By iteratively repeating this process using progressively small sub-regions, the input device can identify the location of the input object.
