Electronic Device Structures With Oleophobic Coatings

An electronic device, comprising:

• a housing;
• a camera in the housing;
• and
• a transparent camera window in the housing that overlaps the camera, wherein the transparent camera window comprises:
• a transparent crystalline member;
• an annealed inorganic adhesion layer on the crystalline member;
• and
• an oleophobic coating on the annealed inorganic adhesion layer.

An electronic device, comprising:

• a housing;
• a component in the housing;
• and
• a transparent crystalline member that overlaps the component;
• an annealed inorganic adhesion layer having a graded mixture of first and second inorganic materials;
• and
• an oleophobic coating on the annealed inorganic adhesion layer.
