Abstract: Embodiments of an anti-glare article and methods for forming the same are disclosed. In one or more embodiments, the anti-glare article includes a substrate having a surface, and a plurality of features disposed on the surface, wherein about 50% or more of the plurality of features comprise a normalized area in the range from about 0.5 to about 1.5, and the normalized area is defined as the relationship (surface area of a feature/average surface area of all features). In some embodiments, about 90% or more of the features have a surface area of about 100 micrometers or less. The anti-glare article exhibits a PPDr of about 5% or less, a transmission haze of less than about 20% and a DOI of less than about 90%. Methods of forming the substrate are also disclosed and include etching a surface of a substrate with an etchant comprising a water soluble metal ion salt.

Abstract: An apparatus for producing anti-glare surfaces includes an etching cream dipping tank and a sub-tank arranged to receive a slurry of etching cream. A pumping unit is fluidly coupled to the etching cream dipping tank and the sub-tank such that the pumping unit is operable to selectively self-circulate the slurry of etching cream in the sub-tank to improve homogeneity of the etching cream and transfer a volume of the homogenized etching cream from the sub-tank to the etching cream dipping tank.

Abstract: Methods of forming a foldable apparatus can involve contacting an existing first major surface of a foldable substrate with an alkaline solution to remove an outer layer to form a new first major surface. In aspects, the alkaline solution comprises about 10 weight % or more of a hydroxide-containing base and/or a pH of about 14 or more. Methods of forming a foldable apparatus can comprise contacting a first major surface of a foldable substrate with a first alkaline detergent solution under sonication. Methods of forming a foldable apparatus can comprise contacting an existing first major surface of a foldable substrate with an acidic solution having a pH from about 3.3 to about 3.5 and a fluorine-containing compound. Methods of forming a foldable apparatus can comprise contacting an existing first major surface of a foldable substrate with a solution comprising fluorosilicic acid.

Abstract: A glass article is provided (and methods of making the same) that includes: a glass substrate comprising a thickness and a first primary surface; and a porosity-graded layer that extends from the first primary surface of the substrate to a first depth within the substrate. The first depth is from about 250 nm to about 3000 nm. The porosity-graded layer comprises a plurality of pores having an average pore size from about 5 nm to 100 nm. The article comprises a single-side average reflectance of less than 9% at an incident angle of 60 degrees across a spectrum from 350 nm to 2000 nm. Further, the porosity-graded layer comprises a surface porosity at the first primary surface and a bulk porosity at the first depth, the surface porosity greater than the bulk porosity.

Abstract: Anti-glare glass-based articles and methods of processing a glass based article to reduce warp are disclosed. A method for processing a glass-based article includes etching a first surface of the glass article to create a first anti-glare surface having a plurality of first anti-glare features and etching a second surface of the glass-based article to create a second anti-glare surface having a plurality of second anti-glare features. At least one of a length, a width, and a diagonal of the glass-based article is greater than or equal to 500 mm. A difference of warp between a first warp value before etching the first surface and the second surface and a second warp value after etching the first surface and the second surface is less than or equal to 0.15 mm across each of one or more 500 mm intervals of length, width, or diagonal of the glass-based article.
