Abstract:
1. An electronic device comprising: a radiation passing layer having a top surface and a bottom surface; a proximity sensor having a radiation emitter and a radiation detector, both positioned below the radiation passing layer; a visibly opaque layer covering the bottom surface of the radiation passing layer except for an opening that allows radiation from the emitter to pass, and scattered radiation to pass to the detector; a radiation shield positioned between the emitter and the detector, and extending to the bottom surface of the radiation passing layer; a cold mirror positioned between the shield and the bottom surface of the radiation passing layer, covering said opening in the visibly opaque layer; and a radiation absorber being a separate piece and of a different material than the shield and positioned to provide a radiation seal between a top surface of the shield and a bottom surface of the cold mirror.
