A glass article including: at least one anti-glare surface having haze, distinctness-of-image, surface roughness, and uniformity properties, as defined herein. A method of making the glass article includes, for example: depositing deformable particles on at least a portion of a glass surface of the article; causing the deposited deformable particles on the surface to deform and adhere to the surface; and contacting the surface having the adhered particles with an etchant to form the anti-glare surface. A display system that incorporates the glass article, as defined herein, is also disclosed. |

1. A method of making a glass article having an anti-glare surface, comprising:
depositing deformable particles on a portion of at least one glass surface of the article comprising contacting the glass surface with a suspension of wax particles, a suspension of polymer particles, or a combination thereof; deforming the deposited deformable particles on the surface by heating to adhere the particles to the glass surface; contacting the glass surface having the adhered particles with an etchant to form the anti-glare surface, wherein contacting comprises exposing the glass surface having the adhered particles to the etchant for about 1 second to about 30 minutes; and removing the adhered particles from the glass surface,wherein the glass surface comprises at least one of a soda lime silicate glass, an alkaline earth aluminosilicate glass, an alkali aluminosilicate glass, an alkali borosilicate glass, a boroaluminosilicate glass, or a combination thereof, the etchant comprises at least one acid selected from HF, H2SO4, or a combination thereof, and the resulting glass article has a haze of less than 30, a distinctness-of-image (DOI 20°) of 25 to 85, a surface roughness (Ra) of 50 to 500 nm, and an average roughness peak-to-valley difference profile of about 0.1 to about 10 micrometers. |
