Anti-glare surface treatment method and articles thereof

摘要

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 sacrificial particles on a surface of the article; and contacting the resulting particulated surface with an etchant. A display system that incorporates the glass article, as defined herein, is also disclosed.

1. A method of making an article having an anti-glare surface, comprising:
depositing glass particles to adhere the particles on at least one glass surface of the article, wherein depositing glass particles on at least one glass surface of the article comprises: forming a concentrated liquid suspension of the glass particles, diluting the concentrated suspension with a liquid diluent, and contacting the at least one glass surface and the diluted suspension; and contacting the at least one glass surface of the article having the deposited and adhered glass particles and an etchant to form the anti-glare surface, and the etchant comprises at least one acid, wherein the anti-glare surface has a haze of from about 0.1 to about 30, a distinctness-of-image (DOI 20°) of from about 25 to about 85, and a surface roughness (Ra) of from about 50 to about 500 nm.
