Systems and methods for displaying art in a manner which resists tipping from external forces while preserving artistic impression are disclosed. An art piece includes an inner core extending from a bottom of a display portion and an outer stabilizing core formed about the inner core. A base includes a recess located within a housing. The recess is configured to snugly receive the stabilizing core. A number of illumination devices are located within the recess and electrically connected to a power supply for illuminating the art piece. In some embodiments, holes may be formed in the base for fastening the base to a surface.

Proposed is a flexible cover window having a folding part, the cover window being a glass-based cover window for a flexible display and including: a plane part provided by corresponding to a plane area of the display, and a folding part provided by continuing to the plane part, by corresponding to a folding area of the display, and by being slimmed to be thinner than the plane part, wherein a depth of layer (DOL) of the plane part is larger than a depth of layer (DOL) of the folding part.

A method of producing glass-based articles having sections of different thicknesses is provided, where a maximum central tension in a thinner section is less than that of a thicker section. The method includes reducing the thickness of a region of a glass-based article that includes a compressive stress layer extending from a surface to a depth of compression to form a glass-based article with multiple thickness regions, and then ion exchanging the glass-based article to form a stress profile in the thinner region that has a maximum central tension that is less than a maximum central tension of a stress profile of the thicker region. The glass articles produced by the method are also provided.

Deadfront articles that include a tactile element formed on a first surface of a substrate and a visual element disposed on a second surface of the substrate opposite the first surface. The tactile element is positioned on the first surface of the substrate in a complimentary fashion to the visual element disposed on the second surface of the substrate. The tactile element may include a surface roughness portion having a surface roughness different than the surface roughness of an area bordering the surface roughness portion. The deadfront articles may be incorporated into an automobile interior to provide a visual and haptic display interface for a user.

A translucent glass pane-type substrate, adapted to serve as a cover element for a photovoltaic cell, the substrate including at least one textured surface intended to be oriented towards the outside of a building and wherein for any texture orientation, the fraction of local surfaces having said texture orientation is less than or equal to 2×10.sup.−4 of a given sampling surface

A method for manufacturing a quartz glass substrate with a coating formed includes: surface roughening for a base surface of the quartz glass substrate, on which the sprayed coating is formed; and a heating treatment of heating the substrate after the surface roughening. The base surface is 0.9 μm or more and 5.0 μm or less in arithmetic mean roughness (Ra) in the surface roughening. The heating treatment is performed at a temperature that is equal to or higher than a strain point (temperature at which the viscosity reaches 10.sup.13.5 Pa.Math.sec) of the quartz glass.
