MULTI-TOUCH SENSOR PATTERNS AND STACK-UPS
First Claim
1. A touch sensor array comprising:
- one of a plurality of row traces or column traces arranged in pairs of opposing and spaced apart comb pattern configurations having opposing fingers facing one another; and
the other of the plurality of row traces or column traces comprising a plurality of cross elements substantially perpendicularly disposed with respect to the opposing fingers on the comb pattern configurations, with each cross element having perpendicularly disposed traces corresponding to the opposing fingers of the comb pattern configurations.

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.

9. A touch sensor array comprising:
-
a plurality of row traces arranged in opposing comb pattern configurations, each opposing comb pattern configuration having finger elements extending toward the opposed comb pattern configuration, and defining finger regions between the finger elements; and a plurality of column traces comprising plural rows of traces and perpendicular cross elements, the rows of traces arranged parallel to the finger elements and extending between each of the finger elements within the finger regions of the opposing comb pattern configurations, and the cross elements extending between the opposing comb pattern configurations continuously over multiple row traces but not extending between the finger regions. - View Dependent Claims (10, 11, 12, 13)
