A method for manufacturing an optical metasurface is configured to operate in a given working spectral band. The method comprises: obtaining a 2D array of patterns, each comprising one or more nanostructures forming dielectric elements that are resonant in said working spectral band, said nanostructures being formed in at least one photosensitive dielectric medium; exposing said 2D array to a writing electromagnetic wave having at least one wavelength in said photosensitivity spectral band, said writing wave having a spatial energy distribution in a plane of the 2D array that is a function of an intended phase profile, so that each pattern of the 2D array produces on an incident electromagnetic wave having a wavelength in the working spectral band, a phase variation corresponding to a refractive index variation experienced by said pattern during said exposure.

A method for manufacturing a glazing. A low-emissivity protected glass piece has a low-emissivity coating applied to a second face thereof and a protective film covering the low-emissivity coating. The glass piece is placed on a surface of a screen printing table, the protective layer being in contact with said surface. Acid etching is performed with an acid paste which attacks the first face of the low-e protected glass piece to print visual markers thereon using a screen printing canvas on the first face. After waiting, the first face of the low-e protected glass piece is washed to remove the acid paste to obtain a permanent frosted finish pattern forming the bird-friendly visual markers on the first face. The protective film is removed to obtain a low-e marked glass having visual markers on one side and a low-e coating on another side, and then the marked glass is tempered.

A method for producing an automotive glazing with an optical sensor device, with the glazing having superior optical qualities, including the steps of applying an enamel obscuration mask on at least one face of at least one glass sheet, where the obscuration mask extends to an area where the at least one optical sensor device will be fixed and includes at least one opening on the automotive interior side so as to be capable of acquiring information through the opening from the optical sensor device intended to be fixed at the at least one opening; drying or firing the enamel obscuration mask; applying a washable cover layer resisting at a temperature of at least 620° C. on the surface of the at least one opening; submitting the glass sheet to a heat treatment above 450° C. during a bending or tempering process; and removing by washing the washable cover layer.

A glass substrate includes a thin portion having a first surface and a second surface opposed to the first surface, a thick portion having a first surface and a second surface opposed to the first surface and having a sheet thickness t.sub.3 that is larger than a sheet thickness t.sub.2 of the thin portion, a connection portion having a first connection surface and a second connection surface, the first connection surface connecting the first surface of the thin portion to the first surface of the thick portion, the second connection surface connecting the second surface of the thin portion to the second surface of the thick portion. The first connection surface has a curvature radius of more than or equal to 400 μm.

A method for manufacturing an ultra-thin glass substrate includes: providing a glass base material preset with n substrate areas and a skeleton area surrounding the substrate areas; at least forming an etching protection layer on an upper surface and a lower surface of each substrate area of the glass base material, respectively; at least etching the skeleton area of the glass base material to separate the substrate areas from the glass base material, and form a stress dissipation edge along an edge of each substrate area; and removing the etching protection layer to get independent glass substrates. A method for manufacturing a display panel is also disclosed. An aim is to prevent quality of the ultra-thin glass substrate from damage caused by scribing wheel cutting or laser cutting, therefore the quality of the ultra-thin glass substrate is improved.
