Abstract:
1. A sensor electrode pattern configured to enable the detection of multiple input objects concurrently disposed in a sensing region of a mutual capacitance sensor, said sensor electrode pattern comprising: a plurality of first sensor electrodes oriented along a first axis; and a plurality of second sensor electrodes oriented along a second axis and configured to be capacitively coupled with said plurality of first sensor electrodes; wherein at least one sensor electrode of said plurality of first sensor electrodes is disposed in a configuration forming multiple crossings with a line that is parallel to said second axis, said multiple crossings occurring proximate to said sensing region of said mutual capacitance sensor, wherein one of at least two of said plurality of first sensor electrodes and at least two of said plurality of second sensor electrodes are interleaved with each other proximate to said sensing region of said mutual capacitance sensor, and wherein one of said plurality of first sensor electrodes and said plurality of second sensor electrodes comprises transmitter sensor electrodes and the other of said one of said plurality of first sensor electrodes and said plurality of second sensor electrodes comprises receiver sensor electrodes.
