Abstract
An electronic device includes a user input assembly. The user input assembly includes a capacitive touch sensor unit having a front side, a light guide overlying the front side, an opaque coating on the light guide, and a light source. The opaque coating is configured to represent indicia and/or ornamentation. The light source is operative to generate light that is transmitted through the light guide to illuminate the user input assembly.
