Touch sensor with spacers supporting a cover panel

摘要

In one embodiment, a touch sensor includes an insulating substrate comprising a first face. The touch sensor further includes a plurality of electrodes comprising one or more conductive materials formed on the insulating substrate. The touch sensor may also include a plurality of spacers extending outwardly from the first face of the first insulating substrate. Each spacer of the plurality of spacers may extend substantially the same distance from the first face of the insulating substrate. The plurality of spacers are operable to maintain a substantially consistent air gap between the plurality of electrodes and a cover panel when the cover panel is attached to the insulating substrate.

1. A touch sensor comprising:
a first insulating substrate comprising a first face; a first plurality of electrodes comprising one or more conductive materials formed on the first insulating substrate; a plurality of spacers disposed in-between the electrodes and disposed on the first face of the first insulating substrate, each spacer of the plurality of spacers extending substantially the same distance from the first face of the first insulating substrate; a cover panel attached to the first insulating substrate and disposed outwardly from the plurality of spacers such that the plurality of spacers are in-between the first insulating substrate and the cover panel; wherein the first plurality of electrodes are disposed closer to the cover panel than any other electrodes in the touch sensor; and wherein the plurality of spacers are operable to maintain a substantially consistent air gap between the first plurality of electrodes and the cover panel.
