Glass, glass-ceramic and ceramic articles with durable lubricious anti-fingerprint coatings over optical and scratch-resistant coatings and methods of making the same

Abstract:

An article that includes: a glass, glass-ceramic or ceramic substrate comprising a primary surface; at least one of an optical film and a scratch-resistant film disposed over the primary surface; and an easy-to-clean (ETC) coating comprising a fluorinated material that is disposed over an outer surface of the at least one of an optical film and a scratch-resistant film. The at least one of an optical film and a scratch-resistant film comprises an average hardness of 12 GPa or more. Further, the outer surface of the at least one of an optical film and a scratch-resistant film comprises a surface roughness (R.sub.q) of less than 1.0 nm. Further, the at least one of an optical film and a scratch-resistant film comprises a total thickness of about 500 nm or more.
