Patent ID: 8564552

Claim:
An assembly, comprising: a first plurality of electrode pairs distributed across an active area of a touchscreen, each electrode pair formed in a pattern, the patterns of the first plurality of electrode pairs decreasing in frequency of snaking from electrode pair to electrode pair in a first direction; and a second plurality of electrode pairs distributed across the active area of the touchscreen, each electrode pair formed in a pattern, the patterns of the second plurality of electrode pairs increasing in frequency of snaking from electrode pair to electrode pair in the first direction; wherein a position of a touch on the touchscreen can be determined in the first direction based on proportionate density of the first plurality of electrode pairs and the second plurality of electrode pairs in an area of the touch; wherein each electrode pair of the first and second plurality of electrode pairs comprises: a drive electrode; and a receive electrode adjacent to and substantially parallel with the drive electrode; wherein drive electrodes in the first plurality of electrode pairs are directly coupled to one another and to a first external electrical connection; wherein drive electrodes in the second plurality of electrode pairs are directly coupled to one another and to a second external electrical connection; and wherein at least one receive electrode in the first plurality of electrode pairs is directly coupled to at least one receive electrode in the second plurality of electrode pairs.
