摘要： 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.

摘要： A tiled display having pixels arranged in rows and columns, and including first and second tiles. The tiles comprise a substrate carrying a matrix of pixels arranged at a pixel pitch. The substrates comprise an edge extending between opposing faces in a depth direction. The substrate edges have a complementary shape, and face one another to establish a seam. The pixel pitch is maintained across the seam. Pixels of the second tile are not interposed between pixels of the first tile. The complementary shape includes a segment of the seam being oblique to the pixel rows, or the substrate edge of the first tile profiled in the depth direction whereby at least a section of the edge is non-perpendicular to the faces. The tiled display can maintain the pixel pitch at the seams at high resolutions (e.g., pixel pitch less than 0.5 mm).

摘要： 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.

摘要： A method for processing a transparent workpiece includes directing a laser beam oriented along a beam pathway through an aspheric optical element and the transparent workpiece. The laser beam impinges the aspheric optical element radially offset from a centerline axis of the aspheric optical element by an offset distance of 30% the 1/e2 diameter of the laser beam or greater. The beam pathway and the transparent workpiece are tilted relative to one another such that the beam pathway has a beam pathway angle of less than 90° relative to an impingement surface at the impingement surface and a portion of the laser beam directed into the transparent workpiece is a laser beam focal line having an internal focal line angle of less than 80° relative to the impingement surface, such that a defect with a defect angle of less than 80° is formed by induced absorption within the transparent workpiece.

In one embodiment, an article includes a silica-containing substrate including greater than or equal to 85 mol % silica, a first surface, a second surface opposite the first surface, and a via extending through the silica-containing substrate from the first surface toward the second surface. The via includes a first diameter at the first surface wherein the first diameter is less than or equal to 100 μm, a second diameter at the second surface wherein the first diameter is less than or equal to 100 μm, and a via waist between the first surface and the second surface. The via waist has a waist diameter that is less than the first diameter and the second diameter such that a ratio between the waist diameter and each of the first diameter and the second diameter is less than or equal to 75%.

摘要： A method for laser processing a transparent workpiece includes forming a contour line that includes defects, by directing a pulsed laser beam output by a beam source through an aspheric optical element positioned offset in a radial direction from the beam pathway and into the transparent workpiece such that the portion of the pulsed laser beam directed into the transparent workpiece generates an induced absorption within the transparent workpiece that produces a defect within the transparent workpiece. The portion of the pulsed laser beam directed into the transparent workpiece includes a wavelength λ, an effective spot size wo,eff, and a non-axisymmetric beam cross section having a minimum Rayleigh range ZRx,min in an x-direction and a minimum Rayleigh range ZRy,min in a y-direction. Further, the smaller of ZRx,min and ZRy,min is greater than FDπw0,eff2/λ, where FD is a dimensionless divergence factor comprising a value of 10 or greater.
