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 (R) from 50 nm to 300 nm. The substrate exhibits a sparkle of less than 5%, as measured by PPD, 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.

Display articles with antiglare surfaces and thin, durable antireflection coatings

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 (PPD) 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.
