Abstract: Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a first central surface area recessed from a first major surface by a first distance and a second central surface area. A second major surface comprises the second central surface area. A blunted edge extends around an entire periphery of the foldable substrate. The blunted edge comprising a first blunted surface area where the blunted edge meets the first major surface and a second blunted surface area where the blunted edge meets the second major surface. Methods comprise laminating the foldable substrate with support layers before removing a peripheral portion of an initial edge of the foldable substrate to form an intermediate edge. The intermediate edge is contacted with an etchant to form the blunted edge. Methods further comprise removing the support layers from the foldable substrate.

Abstract: A method of separating a portion of an object comprising: presenting an object having a thickness; using a laser emission at a wavelength to perforate at least a portion of the thickness of the object sequentially over a length to form a series of perforations between a first portion of the object on one side of the series of perforations and a second portion of the object on the other side of the series of perforations; and applying a stress to the object at the series of perforations to separate the first portion of the object from the second portion of the object, wherein the thickness of the object, at the series of perforations, is transparent to the wavelength of the laser emission.

Abstract: A method includes depositing a surface modification layer on sidewalls of a plurality of cavities of a shaped article. The surface modification layer is formed from a glass material including a mobile component. The shaped article is formed from a glass material, a glass ceramic material, or a combination thereof. At least a portion of the mobile component is migrated from the surface modification layer into surface regions of the sidewalls of the shaped article, whereby subsequent to the migration, the surface regions have a reduced annealing point compared to a bulk of the shaped article. The surface modification layer and the surface regions of the sidewalls are reflowed. A surface roughness of the surface modification layer disposed on the sidewalls following the reflowing is less than a surface roughness of the sidewalls prior to the depositing.

Abstract: A liquid lens can include a first substrate with an interior recess. A second substrate with a bore can be bonded to the first substrate, whereby the interior recess of the first substrate and the bore of the second substrate cooperatively define at least a portion of a cavity of the liquid lens. A first liquid and a second liquid can be disposed in the cavity. A variable interface can be disposed between the first liquid and the second liquid, thereby forming a variable lens. The interior recess of the first substrate can be positioned outside of a sidewall projection of a sidewall surface of the cavity through the first substrate.

Abstract: Embodiments of a glass laminate structure comprising a non-strengthened glass sheet, a strengthened glass sheet, and at least one polymer interlayer intermediate the external and internal glass sheets are disclosed. The strengthened glass sheet can have a thickness ranging from about 0.3 mm to about 1.5 mm, the non-strengthened glass sheet can have a thickness ranging from about 1.5 mm to about 3.0 mm, and the polymer interlayer can have a first edge with a first thickness and a second edge opposite the first edge with a second thickness greater than the first thickness. The glass laminate structures provide advantageous optical properties. The glass laminate structure can be employed to provide a transparent display screen that minimizes image offset between two images formed by two reflections at two surfaces of the strengthened internal glass sheet.
