Electronic Devices Having Optical Diffusers for Optical Components

An electronic device comprising:

• a housing;
• input-output devices mounted in an interior region of the housing;
• an optical component aligned with a transparent region in the housing;
• and
• a diffuser between the transparent region and the optical component, wherein the diffuser comprises a layer of polymer with embedded flakes of inorganic dielectric material that are configured to scatter light, wherein each of the embedded flakes has a stack of dielectric layers with alternating refractive index values forming a thin-film interference filter.

An electronic device, comprising:

• a housing having a transparent region;
• a diffuser having a layer of polymer with embedded thin-film interference filter flakes overlapping the transparent region;
• and
• an optical component configured to receive light through the transparent region and the diffuser.
