Abstract: 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.

Abstract: 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.

Abstract: An optical assembly includes a transparent substrate having a first major surface and a second major surface. The transparent substrate includes one or more damage layers disposed between a first non-damage layer and a second non-damage layer. Elongated laser-induced damage tracks are disposed within the damaged layer(s) to form at least one area pattern so that light directed toward the transparent substrate at an angle that exceeds a predetermined viewing angle (θ) is scattered by the plurality of laser-induced damage tracks. Alternatively, if light is directed toward the transparent substrate at an angle that is less than the predetermined viewing angle (θ), it is transmitted by the transparent substrate.

Abstract: A diffraction element can be employed in a surface display unit to provide diffraction peaks in a manner that reduces or eliminates a screen door effect that is prevalent in pixelated displays that does not have sufficient pixel density. The parameters of the diffraction element can be selected such that the diffraction peaks provide appearance of a larger pixel area than a corresponding physical pixel size. For example, first order diffraction peaks can be placed at a distance of about ⅓ of a nearest subpixel-to-sub-pixel distance. The surface display unit can be employed for any image display application to enhance image quality. For example, a virtual reality headset to remove the screen door effect.

Abstract: A material system for a surface display unit that includes a first side (i.e., a proximal side) that faces a viewer of the surface display unit and a second side (i.e., a distal side) facing away from the viewer. The material system provides at least three appearance states, including a generally opaque first appearance state when the surface display unit is “off” (i.e., not used to display images), a second appearance state in which the material system is illuminated from the first (i.e., proximal) side to display a first image (e.g., information and/or decoration) that is perceptible to the viewer, and a third appearance state in which the material system is illuminated from the second (i.e., distal) side to display a second image (e.g., information and/or decoration) that is perceptible to the viewer. Surface display units, systems, and methods comprising the material system are also disclosed.

Abstract: A distortion-reducing anti-glare (DRAG) structure is disclosed, wherein the DRAG structure includes first and second transparent mediums. The first transparent medium has a first refractive index and a first light-scattering anti-glare (AG) surface. The first AG surface by itself reduces glare but introduces an amount of distortion to the transmitted light. A second transparent medium having a second refractive index greater than the first refractive index is selectively added to the first transparent medium to reduce the amount of distortion in the transmitted light.
