发明名称 USING A PRINTED CIRCUIT TO OFFSET CHARGE DURING CAPACITIVE SENSING
摘要 In a method of capacitive sensing an absolute capacitive sensing signal is driven through at least one of a plurality of routing traces of a printed circuit. Absolute capacitive sensing is performed with at least one sensor electrode of a plurality of sensor electrodes in a sensor electrode pattern. The at least one sensor electrode is coupled with the at least one of the plurality of routing traces. An offsetting signal is transmitted on a parallel conductor overlapping the at least one of the plurality of routing traces, such that charge is offset from the at least one of the plurality of routing traces during the absolute capacitive sensing.
