Abstract: A system such as a vehicle, an appliance, or a mobile phone can include an assembly featuring a decorative layer and a transparent display module. The decorative layer can include ink applied to a substrate. The transparent display module can be mounted to the decorative layer and include an array of pixels disposed behind an outer cover glass. The assembly can be configured such that when the display module is in a first mode, the decorative layer is visible from the cover glass and through the pixel array.

Abstract: Embodiments of this disclosure pertain to articles that exhibit scratch-resistance and improved optical properties. In some examples, the article exhibits a color shift of about 2 or less, when viewed at an incident illumination angle in the range from about 0 degrees to about 60 degrees from normal under an illuminant. In one or more embodiments, the articles include a substrate, and an optical film disposed on the substrate. The optical film includes a scratch-resistant layer and an optical interference layer. The optical interference layer may include one or more sub-layers that exhibit different refractive indices. In one example, the optical interference layer includes a first low refractive index sub-layer and a second a second high refractive index sub-layer. In some instances, the optical interference layer may include a third sub-layer.

Abstract: Embodiments of articles with optical coatings are described herein. According to one embodiment, an article may comprise a substrate having a major surface, and an optical coating disposed on the major surface and forming an anti-reflective surface, the optical coating comprising an anti-reflective coating. The article may exhibit a maximum hardness of about 12 GPa or greater as measured on the anti-reflective surface by a Berkovich Indenter Hardness Test along an indentation depth of about 100 nm or greater. The article may exhibit a single side average light reflectance measured at the anti-reflective surface of about 8% or less over an optical wavelength regime in the range from about 400 nm to about 800 nm. The article may exhibit an average light transmission of about 90% or greater over an optical wavelength regime in the range from about 400 nm to about 800 nm.

Abstract: Durable and scratch resistant articles including low-reflectance optical coating with gradient portion. In some embodiments, an article comprises: a substrate comprising a first major surface; and an optical coating disposed over the first major surface. The optical coating comprises: a second major surface; a thickness; and a first gradient portion. A refractive index of the optical coating varies along a thickness of the optical coating. The difference between the maximum refractive index of the first gradient portion and the minimum refractive index of the first gradient portion is 0.05 or greater. The absolute value of the slope of the refractive index of the first gradient portion is 0.1/nm or less everywhere along the thickness of the first gradient portion. The article exhibits a single side photopic average light reflectance of 3% or less, and a maximum hardness from 10 GPa to 30 GPa.

Abstract: One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be suppressed by inserting a nanoporous crack mitigating layer between the glass substrate and the film.
