摘要： Embodiments of articles including a low-contrast anti-reflection coating are disclosed. The coated surface of such articles exhibits a reduced difference in reflectance between a pristine state and when a surface defect is present. In one or more embodiments, the coated surface of such articles exhibits a first average reflectance in the range from about 0.6% to about 6.0% in a pristine condition and a second average reflectance of about 8% or less after removal of a surface thickness of the anti-reflection coating. In other embodiments, the coated substrate exhibits a second average reflectance of about 10% or less, when the coated surface comprises a contaminant. In some embodiments, the coated substrate exhibits a first color coordinate (a*1, b*1) in a pristine condition and a second color coordinate (a*2, b*2) after the presence of a surface defect such that Δa*b* is about 6 or less.

The diffractive surface region comprises a plurality of structural features that comprises a plurality of different heights in a multimodal distribution. Further, the substrate exhibits a sparkle of less than 4%, as measured by pixel power deviation (PPD140) at an incident angle of 0° from normal, a distinctness of image (DOI) of less than 80% at an incident angle of 20° from normal, and a transmittance haze of less than 20% from an incident angle of 0° from normal.

摘要： One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be suppressed by inserting a nanoporous crack mitigating layer between the glass substrate and the film.

摘要： An article, comprising an optical layer disposed on a transparent layer, can have a maximum hardness of about 10 GigaPascals (GPa) to about 50 GPa. The optical layer can comprise a first portion and a second portion that are contiguous with one another at one major surface the optical layer. The portions may exhibit specific differences in average reflectance value, observed color, and/or angular color shift relative to each other. In some embodiments, a photopic average reflectance of the first portion may differ from an average reflectance of the second portion by about 5% or more. In other embodiments, a color of the first portion can have a color difference from a color of the second portion of about 4 or more in CIE color coordinate space.
