Claim:
1. An input device comprising: a first plurality of capacitive sensor electrodes oriented along a first axis, disposed in a first layer, and configured to update a display screen of said input device; a second plurality of capacitive sensor electrodes oriented along a second axis that differs from said first axis; and wherein a display region of said display screen has a first dimension along said first axis and a second dimension said second axis, wherein at least one capacitive sensor electrode of said first plurality of capacitive sensor electrodes extends fully across said first dimension of said display region, and wherein an opposed pair of said second plurality of capacitive sensor electrodes taken together extends substantially across said second dimension of said display region but no single individual capacitive sensor electrode extends fully across said second dimension of said display region, wherein at least one capacitive sensor electrode of said second plurality of capacitive sensor electrodes comprises prongs and forms multiple crossings with a first line overlapping said display region and perpendicular to said second axis, and wherein each of said prongs is substantially rectangular except for a pointed end configured to reduce cross-coupling with others of said second plurality of capacitive sensor electrodes, and wherein said pointed ends of said opposed pair are arranged such that they are aligned with and oppose one another.
