Abstract: Glass-based substrates are described herein that may be processed by methods including applying a cover article onto a glass-based substrate, submerging the glass-based substrate in an etchant, and maintaining the submersion of the glass-based substrate in the etchant. The glass-based substrate may include a covered surface portion and an exposed surface portion. At least a portion of the covered surface portion may be in direct contact with the cover article. The covered surface portion may not be in contact with the etchant and the exposed surface portion may be in direct contact with the etchant. The etchant may contact the exposed surface portion and the cover article fora time sufficient to etch the exposed surface portion. The cover article may provide a barrier between the etchant and the covered surface portion for the entirety of the submerging.

Abstract: A glass article is provided that includes: a glass substrate comprising a thickness and a primary surface; and a textured region defined by the primary surface. The textured region comprises a low spatial frequency region and a high spatial frequency region substantially superimposed within the low spatial frequency region. Further, the low spatial frequency region comprises an average lateral feature size that exceeds an average lateral feature size of the high spatial frequency region. In addition, the textured region comprises a surface roughness (Ra) from about 10 nm to about 1000 nm.

Abstract: High contrast, glass-based, writeable/erasable front projection screens are provided. The screens include a transparent glass sheet which has a front surface and a back surface separated by a distance d. The back surface is in optical contact with a diffusing element. During use of the projection screen, the glass sheet transmits image light from a projector to the diffusing element and the diffusing element reflects a portion of that light back through the glass sheet to a user. The screens have a user-facing surface that is a writable/erasable surface. In embodiments, the distance d is less than or equal to 0.2 millimeters, the whiteness W of the projection screen is less than or equal to 0.5, and/or the contrast C of the projection screen is at least 75%.

Abstract: Described herein are textured glass-based articles. The textured glass based articles may include a glass-based substrate including a first major surface and a second major surface. At least a portion of one or both of the first major surface and the second major surface is textured, wherein the portion of the one or both of the first major surface and the second major surface that are textured may have a sparkle at 140 ppi of less than or equal to 5% and an uncoupled distinctness-of-image of at least 78%. Methods for making such articles are also described herein.

Abstract: A display article is described herein that includes: a substrate comprising a thickness and a primary surface; a textured surface region; and an antireflective coating disposed on the textured surface region. The textured surface region comprises structural features and an average texture height (Rtext) from 50 nm to 300 nm. The substrate exhibits a sparkle of less than 5%, as measured by PPD140, and a transmittance haze of less than 40%, at a 0° incident angle. The antireflective coating comprises alternating high refractive index and low refractive index layers. Each of the low index layers comprises a refractive index of less than or equal to 1.8, and each of the high index layers comprises a refractive index of greater than 1.8. The article also exhibits a first-surface average photopic specular reflectance (% R) of less than 0.3% at any incident angle from about 5° to 20° from normal at visible wavelengths.
