Abstract
A biometric sensor assembly comprises a substrate to which is mounted a die containing sensor circuitry, at least one conductive bezel having a visual indicator region formed therein, and electrically connected to said die by way of said substrate, a light source, and a light-directing region directing light from the light source to the visual indicator region. The die, the light-directing region, and the bezel are encased in an encapsulation structure such that a portion of a surface of the die and the visual indication region are exposed or at most thinly covered by the encapsulation structure. The light-directing region directs light emitted by the light source within the encapsulation structure to the visual indicator region. Desired indicia in the visual indicator region may thereby be illuminated, while the die and bezel, and optionally the light source, are protected by the encapsulation structure.
