A method of laser bonding glass to metal foil includes contacting a first glass substrate with a first metal foil to create a first contact location; directing a laser beam on the first contact location to bond the first glass substrate to the first metal foil; contacting a second glass substrate with a second metal foil to create a second contact location; and directing the laser beam on the second contact location to bond the second glass substrate to the second metal foil, wherein the first metal foil and the second metal foil each have a thickness from 5 μm to 100 μm, and wherein the laser beam comprises a pulsed laser comprising: a pulse energy from 2.8 μJ to 1000 μJ; and a wavelength such that the first and second glass substrates are substantially transparent to the wavelength.

In a first aspect, a testing assembly for conducting reliability tests on liquid lenses includes a liquid lens, and a test frame arranged to receive the liquid lens. The liquid lens includes a lens body defining a cavity, a first liquid disposed within the cavity, and a second liquid disposed within the cavity that is substantially immiscible with the first liquid such that an interface between the first liquid and the second liquid forms a lens. The test frame includes a front wall, and a back wall oriented substantially parallel to the front wall. The liquid lens mounts to at least one of the front wall or the back wall and the test frame simulates a smart device incorporating a liquid lens.

Disclosed are device display screen protectors comprising a first strengthened substrate sized to cover a display screen of an electronic device, the first strengthened substrate having a central tension value in the range greater than 0 MPa and less than 20 MPa, a surface having a Knoop lateral cracking scratch threshold of at least 3 N.

Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of compression DOC of at least about 125 &#x3bc;m within the glass article. The compressive stress profile includes a single linear segment or portion extending from the surface to the depth of compression DOC. Alternatively, the compressive stress profile may include an additional portion extending from the surface to a relatively shallow depth and the linear portion extending from the shallow depth to the depth of compression.

Strengthened glass with ultra deep depth of compression

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 &#x3bc;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.

Embodiments are directed to strengthened glass articles comprising a thickness t&#x2264;1 mm (1000 &#x3bc;m), an inner region under a central tension CT (in MPa), and at least one compressive stress layer adjacent the inner region and extending within the strengthened glass article from a surface of the strengthened glass article to a depth of layer DOL (in &#x3bc;m), wherein the strengthened glass article is under a compressive stress at the surface CS(in MPa), wherein the strengthened glass article is an alkali aluminosilicate glass article comprising 0-5 mol % LiO, and at least 3 mol % AlO, and wherein the DOL&#x2265;70 &#x3bc;m, and a CS/DOL ratio&#x2265;2.5 MPa/&#x3bc;m.

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.

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.

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 &#x3bc;m up to about 175 &#x3bc;m or, alternatively, to a depth of compression (DOC) in a range from about 90 &#x3bc;m to about 120 &#x3bc;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 &#x3bc;m to 5 &#x3bc;m and has a steeper slope than that of the first portion of the profile. Methods of achieving such stress profiles are also described.

The strengthened glass has a 60% survival rate when dropped from a height of 80 cm in an inverted ball test and a peak load at failure of at least 10 kgf as determined by abraded ring-on-ring testing.
