摘要： A transparent illumination system and related light guide plate is provided. The system is configured to facilitate total internal reflection propagation of light through the light guide plate despite low index of refraction differences between the glass material of the light guide layer and the adjacent layer. The system includes a light source, such as a laser diode, and an optical element to fan out light from the light source in the plane of the light guide plate. The light guide plate includes internal light extraction features.

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 F D = π w 0 , eff 2 λ , where FD is a dimensionless divergence factor comprising a value of 10 or greater.

摘要： A glass article having a low level of grainy appearance that can appear to have a shift in the pattern of the grains with changing viewing angle of a display, or “sparkle.” The glass article—which, in some embodiments, is a transparent glass sheet—has small-angle-scattering properties and/or distinctness-of-reflected-image (DOI), leading to improved viewability in display applications, especially under high ambient lighting conditions. In some embodiments, the antiglare surface of the glass sheet is an etched surface, with no foreign coating present on the antiglare surface.

摘要： Disclosed herein are methods for forming light-transmitting articles comprising depositing a layer comprising a second material on a substrate comprising a first material, and forming a patterned surface on the second material. The first and second materials can have different glass transition temperatures Tg and/or refractive indices n. Additional layers comprising a third material can also be formed over the patterned surface, the third material having a glass transition temperature Tg and refractive index n that may be the same or different from those of the first and second material. Light-transmitting articles formed by such methods, as well as display devices comprising such light-transmitting articles are also disclosed herein.

摘要： A transparent substrate having an antiglare surface with reduced display sparkle. The transparent substrate has a roughened antiglare surface and a diffraction element below the antiglare surface. The diffraction element reduces sparkle by filling gaps between sub-pixels in a pixelated display with orders of diffraction. A display system comprising the transparent substrate and a pixelated display is also provided.
