Glasses, glass ceramics and ceramic articles having durable and slippery anti-fingerprint coatings on optical and scratch resistant coatings and methods of making the same

摘要

A glass, glass ceramic or ceramic substrate having a major surface; at least one of an optical film and a scratch resistant film disposed on the major surface; and disposed on an outer surface of at least one of the optical film and the scratch resistant film With an easy to clean (ETC) coating made from a fluorinated material. At least one of the optical film and the scratch resistant film has an average hardness of 12 GPa or more. Furthermore, the outer surface of at least one of the optical film and the scratch-resistant film has a surface roughness (Rq) of less than 1.0 nm. Further, at least one of the optical film and the scratch resistant film has a total thickness of about 500 nm or greater.
