Opaque White Coating with Non-Conductive Mirror |
| 摘要 |
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 minor structure disposed over the at least one white coating layer. The non-conductive minor 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. |

1. An opaque cover for a capacitive sensor, the cover comprising:
a transparent substrate; at least one white coating layer including white pigments disposed over at least one portion of the transparent substrate; and
a non-conductive mirror structure disposed over the at least one white coating layer, wherein the non-conductive mirror structure comprises a first plurality of first dielectric layers having a first refractive index interleaved with second dielectric layers having a second refractive index, wherein the first and second dielectric layers have dielectric constants below a threshold. |
