A process for room temperature substrate bonding employs a first substrate substantially transparent to a laser wavelength is selected. A second substrate for mating at an interface with the first substrate is then selected. A transmissivity change at the interface is created and the first and second substrates are mated at the interface. The first substrate is then irradiated with a laser of the transparency wavelength substantially focused at the interface and a localized high temperature at the interface from energy supplied by the laser is created. The first and second substrates immediately adjacent the interface are softened with diffusion across the interface to fuse the substrates.

A carrier substrate to be used, when manufacturing a member for an electronic device on a surface of a substrate, by being bonded to the substrate, includes at least a first glass substrate. The first glass substrate has a compaction described below of 80 ppm or less. Compaction is a shrinkage in a case of subjecting the first glass substrate to a temperature raising from a room temperature at 100° C./hour and to a heat treatment at 600° C. for 80 minutes, and then to a cooling to the room temperature at 100° C./hour.

A method for busbar hiding of a heated coating laminated glazing formed by a first glass sheet and a second glass sheet, each having an outer and an inner face. The method also includes performing enamel printing on an inner face of the first glass sheet and/or the second glass sheet, where the enamel forms a pattern. The enamel is fired and the pattern is covered at least in part by a coating, where the coating extends to at least an area of the enamel for applying busbars. At least two silver busbars are applied in the area on top of the extended coating. A thermal treatment is applied on the first and second glass sheets, where the first and second glass sheets are laminated and the coating is provided between the first and second glass sheets.

A multilayer glass stack for a vehicle windshield with improved durability is described. The multilayer glass stack includes an external-facing glass layer, an internal-facing glass layer, and an adhesive interlayer positioned between the external-facing and internal-facing glass layers. The external-facing glass layer may include borosilicate and/or does not include soda lime glass. Methods of manufacturing the multilayer glass stack are also described.

The present invention relates to a resin composition, comprising: a modified vinyl acetal resin which comprises 20 to 80 mol % of ethylene units and 4 to 76 mol % of vinyl alcohol units based on all monomer units constituting the resin, and has an acetalization degree of 5 to 80 mol %; and an alkali metal salt and/or an alkaline earth metal salt of a strong acid, wherein a total content of the alkali metal salt and/or the alkaline earth metal salt of the strong acid is 0.0005 to 0.06 part by mass with respect to 100 parts by mass of the modified vinyl acetal resin.

A flexible display module and a manufacturing method thereof are provided. The flexible display module includes a substrate, a second glue layer, and a display panel disposed in a stack. Wherein, the display panel includes a bending area, and a first groove is defined in a third area of the substrate corresponding to the bending area and filled with a first glue layer. More deformation can be provided and bending stresses can be reduced by the first glue layer and the second glue layer, thereby improving bending resistance of the flexible display module.

Provided is a resin composition used for forming a laminated glass interlayer film or a solar cell encapsulant, the resin composition including an ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer, wherein metal ions constituting the ionomer (A) of the ethylene-unsaturated carboxylic acid-based copolymer includes two or more kinds of polyvalent metal ions.

Embodiments of the disclosure relate to a glass article. The glass article includes a glass sheet having a first major surface and a second major surface. The second major surface is opposite to the first major surface. The glass article also includes a frame made of a plastic material. The plastic material has a coefficient of thermal expansion (a) having units of ppm/° C. The glass article further includes an adhesive bonding the second major surface of the glass sheet to the frame. The adhesive has a shear modulus (G) having units of MPa. The plastic material of the frame and the adhesive are selected such that G≤500,000 α.sup.−3.

A display film includes a transparent glass layer having a thickness of 250 micrometers or less, or in a range from 25 to 100 micrometers. A transparent energy dissipation layer is fixed to the transparent glass layer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater, or from 1 to 2.

A glazing includes a window, the window including along at least one part of at least one edge a profiled bead including a groove for clipping a cover piece onto the profiled bead, the cover piece including, seen in cross section, a harpoon penetrating into the groove during clipping, wherein when the harpoon is situated in the groove, the cover piece further includes on the one hand, farther toward the exterior than the harpoon and outside of the groove, a base situated facing and at a distance from at least one part of the edge surface of the window and on the other hand, farther toward the exterior than the base, a flexible exterior covering, made of a material different from that of the harpoon, situated facing at least one part of the edge surface of the window and having a Shore A hardness between 45 and 90 inclusive.
