A hinged glass article includes wings including glass and a hinge positioned between the wings. The wings fold about the hinge. The hinge includes a glass portion integrally joined to the wings and a polymer portion overlaying the glass portion. The glass portion of the hinge includes a first surface facing away from a second surface thereof. The polymer portion overlays the first surface. The glass portion of the hinge is asymmetric (with the wings unfolded) such that halves of the glass portion of the hinge do not mirror one another about a lengthwise middle of the hinge. Also, the first surface of the glass portion of the hinge is free of small inclusions impinging thereupon that have a linear cross-sectional dimension extending fully thereacross and through a center thereof greater than 2 μm and less than 30 μm.

Hinged glass article

Apparatus and method for treating a substrate, for example texturing a substrate. In some embodiments, a masking material is applied to a surface of the substrate in a predetermined pattern, the surface thereafter contacted with an etchant that removes the masking material. Contacting the surface with the etchant produces multiple co-located textures. In other embodiments, the masking step can be eliminated, and the etchant is applied in a predetermined pattern to produce multiple co-located textures. In still other embodiments, the substrate has a chemical composition, and the substrate is exposed to a leachant that leaches at least one constituent of the chemical composition to produce a substrate with a varying chemical composition at the substrate surface.

In aspects, a concentration of lithium oxide at a surface is greater than a concentration of lithium oxide at a midpoint by from about 0.2 mol % to about 2 mol %. In aspects, a concentration of lithium oxide at a surface is from about 0.2 mol % to about 2 mol %. In aspects, a total concentration of potassium oxide, rubidium oxide, cesium oxide, and francium oxide at a surface is from about 5 mol % to about 15 mol %. In aspects, a ratio of the total concentration of potassium oxide, rubidium oxide, cesium oxide, and francium oxide at a surface to a concentration of lithium oxide at the surface is from about 1 to about 20. Methods include immersing a substrate in a molten salt bath at 380° C. or more for from about 1 minute to about 10 minutes or for from about 3 minutes to about 2 hours.

Foldable substrates, foldable apparatus, and methods of making

Foldable substrates have a first portion, a second portion, and a central portion positioned therebetween with a first transition region having a first central surface area of the central portion with a first average angle. In aspects, the first average angle is from about 176.10 to about 179.9° or from about 177.0° to about 179.9°. In aspects, a polymer angle is from 178.3° to about 179.9° or from about 179.10 to about 179.9°. Methods comprise disposing an etch mask over the first major surface of the foldable substrate before etching the foldable substrate. In aspects, the etch mask comprises a first polymer layer positioned between a first barrier layer and the first major surface. In aspects, the etch mask comprises a plurality of ink-jet printed shapes. Methods of measuring a contrast ratio comprise impinging a transparent apparatus with a collimated beam.

Disclosed herein are apparatuses and methods for measuring electrostatic charge on a surface of a substrate. The apparatuses comprise a substrate mounting platform, a substrate contacting component, and at least one voltage sensor, wherein the apparatus is programmed to independently control the rotational and translation velocity of a roller and/or to measure a voltage of the substrate at multiple points to produce a two-dimensional map of voltage for at least a portion of the substrate.

Method and apparatus for measuring electrostatic charge of a substrate

Apparatus and method for testing a sheet of brittle material comprising the steps of measuring one or more edge features of a sheet of brittle material, imparting a bend to the sheet of brittle material and producing relative motion between the sheet and the bend such that the bend traverses the sheet. A stress can be induced in the sheet as a function of the relative motion and imparted bend, wherein the induced stress corresponds to a predetermined strength value, and the measured one or more edge features can be correlated with the strength value.

Edge strength testing methods and apparatuses

Transparent conductive oxide thin films having a plurality of layers with voids located at each interface. Smooth TCO surfaces with no post growth processing and a largely tunable haze value. Methods of making include applying multiple layers of a conductive oxide onto a surface of a substrate, and interrupting the application between the multiple layers to form a plurality of voids at the interfaces.
