Abstract: An article that includes: a glass-based substrate having opposing major surfaces; a crack mitigating stack disposed on one of the major surfaces; and a scratch-resistant film disposed on the crack mitigating stack that has an elastic modulus greater than or equal to the elastic modulus of the substrate. The stack comprises one or more bi-layers defined by: (a) a first layer comprising an organosilicate material, and (b) a second layer comprising an organosilicate material over the first layer, the first layer having a lower elastic modulus than the elastic modulus of the second layer. The film comprises at least one of a metal-containing oxide, a metal-containing oxynitride, a metal-containing nitride, a metal-containing carbide, a silicon-containing polymer, a carbon, a semiconductor, and combinations thereof. In addition, the article is characterized by an average flexural strength that is at least 70% of an average flexural strength of the substrate.

Abstract: An inspection apparatus including a light source, a sample holding stage, an image capture device, positioned to receive light from the light source after the light has interacted with a sample on the sample holding stage, and a damage metric. The damage metric includes two or more damage levels, and is a function of light in a test image. Further, the damage metric may correlate to visual observation so that an inspection apparatus may mimic how users of devices will perceive damage to the devices. The damage metric may be adjusted to account for different damage types, for example, abrasion and scratch damage.

Abstract: 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. In one or more embodiments, the interface exhibits an effective adhesion energy of about less than about 4 J/m2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer containing an inorganic material between the glass substrate and the film.

Abstract: A glass article having a low level of grainy appearance that can appear to have a shift in the pattern of the grains with changing viewing angle of a display, or “sparkle.” The glass article—which, in some embodiments, is a transparent glass sheet—has small-angle-scattering properties and/or distinctness-of-reflected-image (DOI), leading to improved viewability in display applications, especially under high ambient lighting conditions. In some embodiments, the antiglare surface of the glass sheet is an etched surface, with no foreign coating present on the antiglare surface.
