DISPLAY ARTICLES WITH DIFFRACTIVE, ANTIGLARE SURFACES AND METHODS OF MAKING THE SAME

Abstract:

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.sub.140) at an incident angle of 0.degree. from normal, a distinctness of image (DOI) of less than 80% at an incident angle of 20.degree. from normal, and a transmittance haze of less than 20% from an incident angle of 0.degree. from normal.
