    • Embodiments of anti-glare substrates and articles including the same are disclosed. In one or more embodiments, the anti-glares substrate includes a textured surface with a plurality of features having an average cross-sectional dimension of about 30 micrometers or less. The substrate or article exhibits a transmission haze of 10% or less, a PPDr of about 7% or less or 6% or less, and a DOI of about 80 or less. Method for forming the anti-glare substrates are also disclosed and include etching a surface of a substrate with an etchant having low water solubility to provide an etched surface, and removing a portion of the etched surface. The method includes generating a plurality of insoluble crystals (e.g., any one or more of K?2#191SiF?6#191 and K?3#191AlF?6#191) on the surface while etching the surface. The etchant may include a potassium salt, an organic solvent and a fluoride containing acid.
    • 公开了防眩光基板及其制品的实施例。 在一个或多个实施例中,防眩光基板包括具有多个特征的纹理表面,其平均横截面尺寸为约30微米或更小。 基材或制品的透射雾度为10%以下,PPDr为约7%以下或6%以下,DOI为80以下。 还公开了形成防眩光基板的方法,包括用具有低水溶性的蚀刻剂蚀刻基板的表面以提供蚀刻表面,以及去除蚀刻表面的一部分。 该方法包括在蚀刻表面时在表面上产生多个不溶性晶体(例如,K 2#191SiF 6#191和K 3 3 191 191 F F 6#191中的任何一个或多个)。 蚀刻剂可以包括钾盐,有机溶剂和含氟化物的酸。
