SINGLE LAYER SENSOR PATTERN

摘要

A capacitive sensor array comprises large sensor electrodes and small sensor electrodes formed from a single layer of conductive material. Each sensor electrode of a first set of small sensor electrodes is electrically connected to a first pad. A first axis crosses two or more of the first set of small sensor electrodes, and each sensor electrode of the first set of small sensor electrodes is located on an opposite lateral side of one of the large sensor electrodes from another sensor electrode of the first set. Each sensor electrode of a second set of small sensor electrodes is electrically connected to a second pad. A second axis crosses two or more of the second set of small sensor electrodes, and each sensor electrode of the second set is located on an opposite lateral side of one of the large sensor electrodes from another sensor electrode of the second set.
