Abstract
An opaque cover is provided for a capacitive sensor. The cover includes a transparent substrate, and at least one white coating layer including white pigments disposed over at least one portion of the transparent substrate. The cover also includes a non-conductive mirror structure disposed over the at least one white coating layer. The non-conductive mirror structure includes a number of first dielectric layers having a first refractive index interleaved with second dielectric layers having a second refractive index. The first and second dielectric layers have dielectric constants below a threshold.
