Opaque color stack for electronic device
Abstract:
An opaque cover for a capacitive sensor is provided. The cover includes a transparent substrate and a black color stack disposed adjacent the transparent substrate. The black color stack includes a pigment stack having a first dielectric layer, a second dielectric layer, and a first light absorbing layer positioned between the first and second dielectric layers. The first dielectric layer has a first refractive index. The second dielectric layer has a second refractive index different from the first refractive index. The black color stack also includes a plurality of second light absorption layers interleaved with a plurality of third dielectric layer.
