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 mouse or other device designed to be grasped by a user's hand. Curved sensor pane 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.

Abstract: A touch sensitive device having a dielectric layer between a cover layer and a touch sensor layer is disclosed. The dielectric layer can reduce a negative pixel effect associated with poor grounding of an object touching the device. The dielectric layer can reduce a capacitance per unit area of the device to less than about 0.0305 picofarads per square millimeter, thereby reducing the negative pixel effect. The dielectric layer can have a thickness of about 0.50 millimeters or more and/or a dielectric constant of about 2.3 or less to reduce the negative pixel effect.
