First Claim
Patent Images
1. A panel for a position sensor, comprising:
- a substrate;
drive electrodes extending in a first direction on the substrate, that drive one or more drive signals; and
sense electrodes provided on the substrate, the sense electrodes being capacitively coupled with the drive electrodes and arranged to sense one or more signals, wherein;
each of the sense electrodes comprises a first sense element extending in a second direction substantially perpendicular to the first direction, and at least one second sense element extending in the first direction,each of the second sense elements intersects and connects with one of the first sense elements, andareas of the second sense elements on the substrate are surrounded by the drive electrodes on the substrate.

Abstract
This document discloses systems, methods, and articles of manufactures, related to position sensors and uses therefor. Various patterns of drive electrodes and sense electrodes that can be used to in a panel for a position sensor are shown and described. In various examples, the drive electrodes and sense electrodes can be arranged in a grid-like matrix.
