A switchable optical device is provided having a first substrate (11), a second substrate (12) and a seal (114). The two substrates (11, 12) and the seal (114) are arranged such that a cell having a cell gap is formed and a switchable medium (10) is located inside the cell gap. The first substrate (11) has a first transparent electrode (21) and the second substrate (12) has a second transparent electrode (22). The electrodes (21, 22) are facing towards the cell gap. The two substrates (11, 12) are arranged such that the first substrate (11) has a first region (71) adjacent to a first edge (41) of the first substrate (11) which does not overlap with the second substrate (12) and the second substrate (12) has a second region (72) which does not overlap with the first substrate (11). A first electrically conducting busbar (31) is arranged in the first region (71) and a second electrically conducting busbar (32) is arranged in the second region (72). A first terminal is electrically connected to the first busbar (31) and a second terminal is electrically connected to the second busbar (32). The first substrate (11) and the second substrate (12) each have an edge deletion (116) in which the respective transparent electrode (21, 22) is removed. The edge deletion (116) is complete on the edges non-adjacent to a busbar (31, 32) and there is no edge deletion or only partial edge deletion on edges adjacent to a busbar (31, 32).

A cold-formed glass laminate (100) may include a first ply (108) of 3D formed glass with a first thickness, a first strength, and a first coefficient of thermal expansion. The laminate (100) may also include a second ply (110) of 3D formed glass with a second thickness less than the first thickness, a second strength greater than the first strength, and a second coefficient of thermal expansion. The second coefficient of thermal expansion may be selected to be sufficiently higher than the first coefficient of thermal expansion to induce residual compressive stresses in the first ply (108) due to cold forming therewith. An adhesive layer (112) may be arranged between the first ply (108) and the second ply (110).

The laminated glazing proposed in this invention has an outer glass layer (201) with holes (20) and a thin inner facing glass layer (202) with shorter length dimension whereas the bottom edge (30) does not have holes on it and which does not overlap with the holes (20) in the outer glass layer (201). One or more retention layers (36), comprising reinforcement and adhesive layers, serve to connect the glazing mounting means (32) to both of the glass layers (201, 202) providing a thin laminated glazing with holes (20) that in the event of failure is retained by the mounting means (32).

A method for producing a vehicular structure in which a transparent substrate and an adherend are bonded together by an adhesive includes pasting a protective film on, so as to cover, an adhesive arrangement area in a peripheral part of a vehicle-inner-side surface of the transparent substrate, and arranging an adhesive in the adhesive arrangement area after removing the protective film, and bonding together the transparent substrate and the adherend with the adhesive.

The trend towards increasing the glazed area in automobiles has reduced the potential locations for mounting cabin lighting. This is especially true for vehicles having large panoramic glazing. Attempts to utilize integrated light sources within the glazing have had mixed results. Embedded LEDs in the laminate tend to be too bright for night driving. Edge feed illumination with light dispersing elements on the glass to date have only been able to provide low intensity levels. Both approaches tend to reduce visibility and aesthetics in the off state. The current invention provides a means and a method to produce a laminate which provides bright cabin lighting without compromising the function of the glazing to serve as a window, by creating a light dispersing layer that is substantially invisible when in the off state and very bright in the on state.

Provided is a thin glass laminate, which is prevented from being broken by bending of a thin glass, and which is excellent in bending durability. The thin glass laminate of the present invention includes a resin film and a thin glass arranged at least on the resin film, wherein the thin glass has a thickness of from 30 μm to 150 μm, and wherein at least part of an end surface of the thin glass is formed of an inclined surface extending downward and outward and/or a curved surface. In one embodiment, at an upper end of the thin glass, at least part of the end surface is formed of the inclined surface extending downward and outward or the curved surface.

The electrical element and the power supply point are disposed on the second surface or inside the interlayer film at or near a peripheral edge portion of the second surface. The wiring is connected to the power supply point, is run out from the power supply point, is run out from the power supply point toward the third surface, and extends through the interlayer film.

Embodiments of the present disclosure may generally relate to systems, apparatus, and/or processes directed to a manufacturing process flow for packages that include one or more glass layers that include patterning features, such as electrically conductive traces, RDLs, and vias within the packages. In embodiments, a package may include a glass layer with a first side and a second side opposite the first side, where the glass layer is a dielectric layer. The package may include another layer coupled with the first side of the glass layer, and a pattern on the second side of the glass layer to receive a deposited material in at least a portion of the pattern.
