A vehicular variable reflectance mirror reflective element includes a rear glass substrate joined with a front glass sheet via a perimeter seal. An electrochromic medium disposed in an interpane cavity established between the rear glass substrate and the front glass sheet and bounded by the perimeter seal. With the rear glass substrate joined with the front glass sheet, the front glass sheet is cut at a front glass substrate portion to form a front glass substrate. A back plate is attached at the rear of the rear glass substrate. With the front glass sheet cut at the front glass substrate portions to form the front glass substrate having the rear glass substrate joined therewith via the perimeter seal, and with the back plate fixtured at a finishing tool, the cut edges of the front glass substrate are processed to provide a finished perimeter edge of the front glass substrate.

A cover glass sheet configured to cover at least a display device, having an outer sheet face and an inner sheet face where the inner sheet face faces the display device and wherein the outer sheet face includes (a) at least a display zone (1) allowing visualization of at least part of a screen of the display device, the display zone having a perimeter, P.sub.display; and (b) at least an opaque zone (2) corresponding to a layer of opaque paint being added at the exception of the display zone, to all or part of the remaining inner sheet face and directly surrounding at least 10-100% of the display perimeter, the opaque zone has a mean surface roughness defined by an opaque arithmetic amplitude value, Ra.sub.(op). The outer sheet face further includes at least one textured zone covering between 0.5% to 99.5% of the opaque zone.

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.

An article is described herein that includes: a glass-based substrate comprising opposing major surfaces; a crack mitigating composite over one of the major surfaces, the composite comprising an inorganic element and a polymeric element; and a hard film disposed on the crack mitigating composite comprising an elastic modulus greater than or equal to the elastic modulus of the glass-based substrate. The crack mitigating composite is characterized by an elastic modulus of greater than 30 GPa. Further, the hard film comprises at least one of a metal-containing oxide, a metal-containing oxynitride, a metal-containing nitride, a metal-containing carbide, a silicon-containing polymer, a carbon, a semiconductor, and combinations thereof.

A camera module according to one embodiment comprises: a barrel provided with at least one lens; a retainer having an inner space and accommodating the barrel in the inner space; a holder coupled to the lower portion of the retainer; a housing disposed on the lower side of the holder and accommodating a printed circuit board; and a cover part mounted on the retainer and disposed in front of the lens. The cover part comprises: a cover glass; a first reflection suppression layer disposed on the upper side of the cover glass; a heating layer disposed on the lower side of the glass cover; and a second reflection suppression layer disposed on the lower side of the heating layer.

The disclosure relates to an improved glass product having a multifunctional coating or a durable top coat over a functional coating. The glass product may include a functional coating on that is most effective on a surface exposed to various mechanical and chemical elements. The disclosed coating provides a durable protective coating over the functional layer to provide protection over the functional layer on an exposed surface. Alternatively, the functional coating may be applied to the protective coating with a porous, nano-structured surface, which protects the functional coating applied thereto.

An article can include a non-light-emitting, variable transmission device and a coating disposed between the non-light-emitting, variable transmission device and an ambient outside the article. In an embodiment, the article has a ΔE of at most 6.5. In another embodiment, the coating includes a plurality of layers including a first layer having a refractive index of at least 2.2 and a thickness of at least 10 nm. The coating can be used to help reduce color differences seen when the non-light-transmitting, variable transmission device is taken to different transmission states. In a particular embodiment, the coating can provide a good balance between color difference and luminous transmission.
