ANTI-SPARKLE SUBSTRATES AND METHODS OF MAKING THE SAME

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.
