ROUTING TRACE COMPENSATION

摘要

A capacitive input device includes first and second pluralities of sensor electrodes disposed in a first region of a substrate. The first and second pluralities of sensor electrodes are substantially orthogonal to one another. The first region is configured to overlap a display screen. At least one routing trace is disposed in a second region of the substrate and is ohmically coupled to a sensor electrode of one of the first and second pluralities of sensor electrodes and also to a processing system. The second region comprises a non-display screen overlapping portion of the substrate. A compensation trace is disposed in the second region and ohmically coupled to the processing system. The compensation trace has substantially the same length as and is substantially parallel and proximate to the at least one routing trace. The compensation trace is not ohmically coupled to any sensor electrode located in the first region.
