IPC: C03C17/34
Abstract: A glass-based assembly includes a glass or glass-ceramic substrate comprising a surface. The surface has flaws, such as a population of small cracks extending into the surface, whereby the substrate is weakened relative to ideal strength thereof. The assembly further includes a coating coupled to the substrate and overlaying at least some of the flaws. Ultimate strength of the substrate with the coating coupled thereto is greater than that of the substrate alone, without the coating.

In some embodiments, an article comprises: a substrate comprising a first major surface; and an optical coating disposed over the first major surface. The optical coating comprises: a second major surface; a thickness; and a first gradient portion. A refractive index of the optical coating varies along a thickness of the optical coating. The difference between the maximum refractive index of the first gradient portion and the minimum refractive index of the first gradient portion is 0.05 or greater. The absolute value of the slope of the refractive index of the first gradient portion is 0.1/nm or less everywhere along the thickness of the first gradient portion.

Abstract: A display article is described herein that includes: a substrate comprising a thickness and a primary surface; a textured surface region; and an antireflective coating disposed on the textured surface region. The textured surface region comprises structural features and an average texture height (Rtext) from 50 nm to 300 nm. The substrate exhibits a sparkle of less than 5%, as measured by PPD140, and a transmittance haze of less than 40%, at a 0° incident angle. The antireflective coating comprises alternating high refractive index and low refractive index layers. Each of the low index layers comprises a refractive index of less than or equal to 1.8, and each of the high index layers comprises a refractive index of greater than 1.8. The article also exhibits a first-surface average photopic specular reflectance (% R) of less than 0.3% at any incident angle from about 5° to 20° from normal at visible wavelengths.
