  • Patent number: 10955311
    Abstract: Apparatus and methods of for measuring stress incurred by a cover glass of a handheld device when the cover glass contacts a surface during a drop event. A transparent solid piece of material with a drop surface and a back surface is provided and oriented to receive a dropped handheld device so that the cover glass contacts the drop surface. At least two optical detectors are directed at the back surface of the transparent material to obtain image data including a plurality of pixel points.

  • Patent number: 10611674
    Abstract: Disclosed are alkali aluminosilicate glasses having unexpected resistance to indentation cracking. The glasses obtain this high resistance as a result of a high level of surface compression accompanied by a shallow depth of layer. The advantaged glasses show greater resistance to radial crack formation from Vickers indentation than glasses with the same compressive stress, but higher depths of layer.

  • Patent number: 10556825
    Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of layer DOL of about 130 ?m up to about 175 ?m or, alternatively, to a depth of compression (DOC) in a range from about 90 ?m to about 120 ?m within the article. The compressive layer has a stress profile that includes a first substantially linear portion extending from a relatively shallow depth to the DOL or DOC and a second portion extending from the surface to the shallow depth. The second portion is substantially linear at a depth from 0 ?m to 5 ?m and has a steeper slope than that of the first portion of the profile. Methods of achieving such stress profiles are also described.

  • Publication number: 20190047909
    Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of at least about 45 ?m within the article are provided. In one embodiment, the compressive stress profile includes a single linear segment extending from the surface to the depth of compression DOC. Alternatively, the compressive stress profile includes two linear portions: the first portion extending from the surface to a relatively shallow depth and having a steep slope; and a second portion extending from the shallow depth to the depth of compression. The strengthened glass has a 60% survival rate when dropped from a height of 80 cm in an inverted ball drop test and a peak load at failure of at least 10 kgf as determined by abraded ring-on-ring testing. Methods of achieving such stress profiles are also described.
