Abstract: Anti-sparkle substrates include a first major surface with a textured surface having a surface roughness Ra from 0.03 micrometers to 0.09 micrometers. The anti-sparkle substrate is a glass-based substrate or a ceramic-based substrate. The anti-sparkle substrate can exhibit a haze from 3% to 40% and a sparkle from 1% to 3.8%. Methods include chemically strengthening an existing first major surface, abrading the existing first major surface to form an intermediate first major surface, and etching the intermediate first major surface to form the first major surface of the anti-sparkle substrate.

Abstract: Described herein are textured glass-based articles. The textured glass based articles may include a glass-based substrate including a first major surface and a second major surface. At least a portion of one or both of the first major surface and the second major surface is textured, wherein the portion of the one or both of the first major surface and the second major surface that are textured may have a sparkle at 140 ppi of less than or equal to 5% and an uncoupled distinctness-of-image of at least 78%. Methods for making such articles are also described herein.

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.
