Ambient light sensor window coatings for electronic devices

An electronic device having an interior and an exterior, the electronic device comprising:

• a transparent layer having a first surface that faces the interior and an opposing second surface;
• a display that is overlapped by the transparent layer;
• and
• a coating on the first surface of the transparent layer, wherein the coating includes a physical vapor deposition thin-film coating and an antireflection coating between the physical vapor deposition thin-film coating and the transparent layer.

An electronic device comprising:

• a transparent structure;
• a display that is overlapped by the transparent structure;
• and
• a coating on a portion of the transparent structure, wherein the coating comprises a physical vapor deposition thin-film coating and a stack of dielectric layers interposed between the physical vapor deposition thin-film coating and the transparent structure.
