Apparatuses and methods of false touch filtering are described. One device includes a controller and a capacitance sensing array including multiple sense elements (e.g., intersections of TX and RX electrodes). The controller includes a capacitance sensing circuit coupled to the capacitance sensing array, and a filter circuit coupled to the output of the capacitance sensing circuit. The controller is configured to receive, from the capacitance sensing circuit, data representing capacitances of the sense elements, process the data to identify activated sense elements, and filter the data to remove false touch events based on a spatial relationship of activated sense elements. |
