  • Patent number: 10730791
    Abstract: Embodiments of a glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0·t up to 0.3·t and from greater than 0.7·t, comprise a tangent that is less than about ?0.1 MPa/micrometers or greater than about 0.1 MPa/micrometers, are disclosed. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0·t to about 0.3·t). In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a point between the first surface and the second surface and increases from the point to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness.

  • Patent number: 10663791
    Abstract: A material system for a surface display unit that includes a first side (i.e., a proximal side) that faces a viewer of the surface display unit and a second side (i.e., a distal side) facing away from the viewer. The material system provides at least three appearance states, including a generally opaque first appearance state when the surface display unit is “off” (i.e., not used to display images), a second appearance state in which the material system is illuminated from the first (i.e., proximal) side to display a first image (e.g., information and/or decoration) that is perceptible to the viewer, and a third appearance state in which the material system is illuminated from the second (i.e., distal) side to display a second image (e.g., information and/or decoration) that is perceptible to the viewer.

  • Publication number: 20200148591
    Abstract: Ion-exchanged glass ceramic articles described herein have a stress that decreases with increasing distance according to a substantially linear function from a depth of about 0.07 t to a depth of about 0.26 t from the outer surface of the ion-exchanged glass ceramic article from a compressive stress to a tensile stress. The stress transitions from the compressive stress to the tensile stress at a depth of from about 0.18 t to about 0.25 t from the outer surface of the ion-exchanged glass ceramic article. An absolute value of a maximum compressive stress at the outer surface of the ion-exchanged glass article is from 1.8 to 2.2 times an absolute value of a maximum central tension (CT) of the ion-exchanged glass article, and the glass ceramic article has a fracture toughness of 1 MPa?m or more as measured according to the double cantilever beam method.
