Abstract: A substrate for a display article includes: a primary surface; a textured region on at least a portion of the primary surface, the textured region comprising surface features that reflect a random distribution, each of the surface features comprising a perimeter that is parallel to a base-plane extending through a thickness of the substrate below the textured region, wherein the perimeter is elliptical. The textured region can further include (i) one or more higher surfaces residing at a higher mean elevation from the base-plane and (ii) one or more lower surfaces residing at a lower mean elevation from the base-plane that is closer to the base-plane than the higher mean elevation. The higher mean elevation can differ from the lower mean elevation by a distance within a range of 0.05 μm to 0.70 μm.

Abstract: A patterned article and a method of making the patterned article. The patterned article comprises a glass substrate and black matrix segments. The black matrix segments are in the form of a pattern and at least one of the segments has a line width of 8 μm or less. The article also comprises an adhesion agent positioned between the glass substrate and the black matrix segments. The adhesion agent provides at least one of: a total surface energy of 65 mN/m or less and at least a 30% reduction in surface polarity compared to a control untreated glass surface as determined by H2O and diiodomethane contact angle and application of the Wu model.

Abstract: Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.
