Abstract
A touch sensitive device that includes a touch sensor having an opaque passivation layer is disclosed. The opaque passivation layer can be made from an organic or inorganic material, such as acrylic. The opaque passivation layer can be positioned in the touch sensitive device between the cover material of the device and conductive traces located on the touch sensor to hide the conductive traces from the user's view and protect the conductive traces from corrosion. Processes for making the touch sensitive devices that include a touch sensor having an opaque passivation layer are also disclosed.
