Abstract: A display article is described herein that includes: a substrate comprising a thickness and a primary surface; and the primary surface having defined thereon a diffractive surface region. 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.

Abstract: An article includes a glass, glass-ceramic or ceramic substrate including a primary surface. A functional coating is disposed over the primary surface of the substrate. The coating includes a first portion disposed over the primary surface. One or more interrupting layers are disposed over the first portion. A second portion is disposed over the one or more interrupting layers. The one or more interrupting layers includes a microstructure different than one of the first and second portions and the coating has an average optical transmittance greater than about 10% over the visible wavelength range from about 450 nm to about 650 nm.

Abstract: A coated article with a substrate having a major surface that comprises a first portion and a second portion that is curved or faceted; and an optical coating on the major surface that forms an anti-reflective surface. A first direction is normal to the first portion and is not equal to a plurality of second directions that are normal to the second portion, and the angle between the first direction and each of the second directions is from about 10 degrees to 60 degrees. Further, the coated article exhibits at the first and second portion a hardness of about 8 GPa or greater at an indentation depth of about 100 nm or greater. Further, the coated article exhibits a single side maximum reflectance of about 3% or less as the first and second portion, wherein the reflectance is measured in a range from about 425 nm to about 950 nm.
