Abstract: Embodiments of a curved display assembly are disclosed. The assembly includes a glass sheet having first and second major surfaces. The second major surface defines a first curvature of the glass sheet, and the first curvature has a bend axis. The assembly also includes a curved display having a second thickness between first and second display surfaces. The display has a display region and two overhanging edges adjacent to the display region and parallel to the bend axis. A first adhesive bonds the second display surface to the second major surface in the display region. A second adhesive is disposed between each of the two overhanging edges and the second major surface. The second adhesive has a higher elastic modulus than the first adhesive. The overhanging edges each extend a distance outside of the display area that is at least three times the second thickness of the curved display.

Abstract: Disclosed is a glass article. The glass article includes a cold-formed glass sheet having a first major surface and a second major surface. The second major surface is opposite to the first major surface. The first major surface has a curvature with a variable radius of curvature including a minimum radius of curvature at a vertex of the curvature. The curvature extends in a first direction from the vertex and in a second direction from the vertex. The first direction is opposite to the second direction. The variable radius of curvature continuously increases with increasing distance from the vertex in the first direction and in the second direction.

Abstract: A method for making a glass laminate sheet including: selecting a core glass composition and a clad glass composition combination for a glass laminate structure; determining and comparing the viscosity and coefficient of thermal expansion (CTE) profiles for each of the selected core and the clad glass compositions with each other over a temperature range of interest including the onset of viscoelasticity to ambient temperature; and processing the selected core and clad glass composition in a laminate fusion draw apparatus to form a laminate glass sheet in accordance with at least one difference condition for the clad effective coefficient thermal expansion (CTEeff core) and the core effective coefficient thermal expansion (CTEeff core). Another method for making a glass laminate sheet includes controlling the cooling rate to control the resulting strength of the laminate.

Abstract: Embodiments of the disclosure relate to a method of controlling the flow of fluid, such as air, between a stack of glass sheets during a co-sagging process. In embodiments, this involves a particular method and certain mechanical means of applying force at or near the edges and/or corners of a stack of glass sheets during a co-sagging process. In other embodiments, this involves creating low pressure regions at or near the edges and/or corners during the co-sagging process. In particular, controlling the flow of fluid between glass sheets is particularly suitable for preventing shape mismatch between two glass sheets having different thicknesses and/or compositions.

Abstract: A method of controlling compaction including obtaining a plurality of sets of process conditions for a plurality of glass ribbons, measuring a compaction value for a glass sheet cut from each glass ribbon of the plurality of glass ribbons, correlating the compaction to the process conditions. The method further includes selecting a predetermined cooling curve including a plurality of cooling rates, modifying the cooling curve by varying cooling rates of the plurality of cooling rates, calculating a predicted compaction value for a glass sheet cut from a glass ribbon drawn using the modified cooling curve, and repeating the modification and predicting until compaction is minimized.
