Abstract
Electrode matrices for capacitive touch-sensing are provided. An electrode matrix may include a plurality of electrodes separated by gaps. Each electrode may include a plurality of spaced apart conductors electrically connected at opposed ends by respective tie structures. The conductors of each electrode may be electrically bridged at intervals by a plurality of jumpers. The electrode matrix may further include a plurality of pseudo jumpers positioned within the gaps and configured to be non-conductive across their entire lengths.

20. An electrode matrix for a capacitive touch-sensing display device, comprising:
-
a plurality of electrodes separated by gaps, each electrode including a plurality of spaced apart conductors electrically connected at opposed ends by respective tie structures, the conductors of each electrode being electrically bridged at intervals by a plurality of jumpers; and a plurality of pseudo jumpers positioned within the gaps, the pseudo jumpers having a substantially similar size and shape as the conductor jumpers, the pseudo jumpers including one or more electrical discontinuities which render the pseudo jumpers electrically non-conductive across their entire lengths; wherein a spatial density of the jumpers and pseudo jumpers is substantially the same.
