DISPLAY ARTICLES WITH DIFFRACTIVE, ANTIGLARE SURFACES AND THIN, DURABLE ANTIREFLECTION COATINGS

摘要

A display article is described herein that includes: a substrate comprising a thickness and primary surface; a diffractive surface region defined by the primary surface; and an antireflective coating disposed on the diffractive surface region. The diffractive surface region comprises structural features that comprise different heights in a multimodal distribution. The substrate exhibits a sparkle of < 4%, and a transmittance haze of 1.8. The article exhibits a first-surface average visible specular reflectance of less than 0.2% at an incident angle of 20°, and a maximum hardness of ≥ 8 GPa in a Berkovich Indenter Hardness Test.
