Abstract: A method of making a strengthened glass article includes providing a flat glass article having a select contour and a glass surface covered by a protective coating layer. The protective coating layer is removed from the glass surface without touching the glass surface with any solid object. Immediately after the protective coating layer is removed from the glass surface, the flat glass article is subjected to an ion-exchange process to strengthen the flat glass article and improve the resistance of the flat glass article to subsequent damage.

Abstract: The present disclosure relates to glass articles for use as a touchscreen substrate for use in a portable electronic device, particularly comprising an alkali-free aluminosilicate glass exhibiting a high damage threshold of at least 1000g, as measured by the lack of the presence of radial cracks when a load is applied to the glass using a Vickers indenter, a scratch resistance of at least 900g, as measured by the lack of the presence of lateral cracks when a load is applied by a moving Vickers indenter and a linear coefficient of thermal expansion (CTE) over the temperature range 0-300 C which satisfies the relationship: 25 x 10-7/C ≤ CTE ≤ 40 x 10-7/C.

Abstract: Methods for separating a sheet of brittle material include the step of providing a sheet of brittle material, such as a glass sheet, with a strain point and a melting point. The method further includes the step of providing a first heating irradiation to a first radiation zone on an outer surface of the sheet, wherein a radiated portion of the outer surface of the sheet is heated to a temperature above the strain point and below the melting point. The method further includes the steps of cooling the radiated portion to create residual stress within the cooled radiated portion, contacting the cooled radiated portion of the sheet such that the residual stress facilitates formation of an initial crack open to the outer surface of the sheet, and propagating the initial crack.

Abstract: A tiled display having pixels arranged in rows and columns, and including first and second tiles. The tiles comprise a substrate carrying a matrix of pixels arranged at a pixel pitch. The substrates comprise an edge extending between opposing faces in a depth direction. The substrate edges have a complementary shape, and face one another to establish a seam. The pixel pitch is maintained across the seam. Pixels of the second tile are not interposed between pixels of the first tile. The complementary shape includes a segment of the seam being oblique to the pixel rows, or the substrate edge of the first tile profiled in the depth direction whereby at least a section of the edge is non-perpendicular to the faces. The tiled display can maintain the pixel pitch at the seams at high resolutions (e.g., pixel pitch less than 0.5 mm).

Abstract: A method of improving strength of a chemically-strengthened glass article comprises exposing a target surface of the glass article to an ion-exchange strengthening process, the ion-exchange strengthening process generating a chemically-induced compressive layer in the glass article. Thereafter, dynamic interfacing of the target surface of the glass article with a sheared magnetorheological fluid is performed to remove at least a portion of the chemically-induced compressive layer from the glass article, wherein the parameters of the dynamic interfacing of the glass article with the sheared magnetorheological fluid are such that a thickness of the removed portion of the chemically-induced compressive layer is less than approximately 20% of the chemically-induced compressive layer.
