Multi-touch sensor patterns and stack-ups
First Claim
1. A touch sensor array comprising:
- at least one conducting layer forming touch sensor traces comprising a plurality of row traces and a plurality of column traces disposed in an active region of the touch sensor array;
a webbed ground plane having a webbed pattern disposed in at least the active area, wherein the webbed pattern;
has a plurality of openings aligned with respect to the touch sensor traces,is grounded, andis distinct from the at least one conducting layer;
a routing layer, distinct from the at least one conducting layer forming the touch sensor traces, the routing layer having routing lines aligned with respect to the active region of the touch sensor array, the routing lines disposed with respect to the webbed pattern such that the routing lines follow the webbed pattern, the routing layer distinct from the webbed ground plane; and
wherein the webbed ground plane is disposed between the routing layer and the at least one conducting layer and shields the touch sensor traces from the routing lines.

Abstract
Capacitive multi-touch sensor panels in which both row and column traces may be formed on a single conducting surface are disclosed. These stack-ups may be made thinner and more flexible allowing them to be particularly well-suited for curved or other non-flat touch sensor panels, such as those that might be present on a mouse or other device designed to be grasped by a user'"'"'s hand. Curved sensor panel arrays that may be formed from flat substrates are also disclosed. These sensor panel configurations may include channels around the periphery of the array. These channels allow the flat array to lie flat when applied to a curved surface, such as the inside of the curved surface. The pattern of the touch sensor elements may be adjusted across the array to avoid the channels.

20. A touch sensor array comprising:
-
a first conducting layer comprising a plurality of rows of row elements, a plurality of columns of column elements, and column traces that connect the plurality of columns of column elements; a second conducting layer comprising one or more groups of row traces, each group having a plurality of row traces having a first portion that extends continuously along a column direction across plural rows of row elements and a second portion that extends along a row direction for connection to ones of the row elements within the plurality of rows, each first portion overlying row elements on the first conducting layer such that the row elements of the first conducting layer shield the first conducting layer from the first portions; and one or more channels disposed in the first and second conducting layers and extending from a periphery portion of the array to a predetermined distance toward, but not extending to, the center of the array from the periphery portion. - View Dependent Claims (21, 22, 23, 24)
