Abstract
A control panel and method of manufacturing a control panel that can be used with an electrically sensitive control device (e.g., a touch sensor, etc.) is disclosed. The control panel includes a substrate layer having a first surface and a second surface. A conductive coating is provided that is viewable from the first surface. The conductive coating defines at least one of a background area and a fill area. The background area is electrically isolated from the fill area. According to one embodiment, the background area and the fill area are both defined by the conductive coating.
