    摘要: 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.

    摘要: 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.

    摘要: A method of forming a textured glass article comprises: submerging an aluminosilicate glass article in an etchant to an upper submerging depth from a surface of the etchant and at a tilting angle, wherein the aluminosilicate glass article comprises a first major surface and a second major surface opposite the first surface, wherein the tilting angle is a smallest angle between a normal to the first major surface and a vertical; holding the aluminosilicate glass article in the etchant for a holding time; and after the holding time, cycling the aluminosilicate glass article in the etchant between the upper submerging depth and a lower submerging depth deeper than the upper submerging depth for a cycling time.
