    Abstract: Methods for forming holes in a substrate by reducing back reflections of a quasi-non-diffracting beam into the substrate are described herein. In some embodiments, a method of processing a substrate having a first surface and a second surface includes applying an exit material to the second surface of the substrate, wherein a difference between a refractive index of the exit material and a refractive index of the substrate is 0.4 or less, and focusing a pulsed laser beam into a quasi-non-diffracting beam directed into the substrate such that the quasi-non-diffracting beam enters the substrate through the first surface. The substrate is transparent to at least one wavelength of the pulsed laser beam. The quasi-non-diffracting beam generates an induced absorption within the substrate that produces a damage track within the substrate.

    Abstract: Processes of chamfering and/or beveling an edge of a glass or other substrate of arbitrary shape using lasers are described herein. Three general methods to produce chamfers on glass substrates are disclosed. The first method involves cutting the edge with the desired chamfer shape utilizing an ultra-short pulse laser. Treatment with the ultra-short laser may be optionally followed by a CO 2 laser for fully automated separation. The second method is based on thermal stress peeling of a sharp edge corner, and it has been demonstrated to work with different combination of an ultrashort pulse and/or CO 2 lasers. A third method relies on stresses induced by ion exchange to effect separation of material along a fault line produced by an ultra-short laser to form a chamfered edge of desired shape.

    Abstract: Display devices and antiglare layers that minimize glare and the appearance of sparkle are described. One type of display device includes a pixel substrate, having a pixel array, and an antiglare layer. The antiglare layer has a surface roughness with a spatial frequency such that a typical focal length of the antiglare layer is either at least four times larger than an optical distance between a surface of the array of pixels and the antiglare layer, or at least three times smaller than the optical distance between the surface of the array of pixels and the antiglare layer. In some embodiments, a pixel pitch of the array of pixels is less than 120 µm. In some embodiments, the antiglare layer may have a power spectral density that is elliptical, with a minor axis of the power spectral density aligned with a color direction of the array of pixels.
