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.

Abstract: A touch sensor may be formed from a flexible substrate such as a sheet of polymer. The flexible substrate may have a main rectangular portion and a protruding portion. Capacitive touch sensor electrodes may be formed on the upper and lower surfaces of the flexible substrate. Signal lines may be coupled to the touch sensor electrodes. The ends of the signal lines may extend onto the protruding portion. Signal lines may be formed on upper and lower surfaces of the flexible substrate. The signal lines may be coupled to circuitry on a printed circuit using a connector that receives the end of the protruding portion. Ground structures on the protruding portion may be configured to overlap the signal lines or may be laterally interposed between upper surface signal lines and lower surface signal lines.

Abstract: Touch sensor panels typically include a plurality of layers that can be stacked on top of each other. When the touch sensor panel is used in a bright environment, incident light can hit the interfaces between those layers of the stackup having mismatched refractive indices and can reflect off those interfaces. The light reflected from those interfaces can give rise to the appearance of fringes on the touch sensor panel, which can be visually distracting. In order to reduce the appearance of these fringes, embodiments of the disclosure are directed to the addition of an index matching passivation layer between a conductive layer of traces and an adhesive layer in the touch sensor panel stackup.
