This disclosure relates to a method for strengthening an edge of a glass plate, a glass, and a display apparatus, wherein the article comprises a side surface located at the edge, and the method for strengthening an edge of an article comprises the steps of: applying an etching paste at least to the side surface of the article to perform etching so as to strengthen the edge of the article; and removing the etching paste.

A method of fabricating a flexible substrate assembly includes forming a first polyimide layer on a rigid support base, wherein the step of forming the first polyimide layer includes incorporating in a polyamic acid solution, an adhesion promoting agent and a release agent for achieving different adhesion strength at two opposite sides of the first polyimide layer, and forming a flexible second polyimide layer on the first polyimide layer, the second polyimide layer being adhered in contact with the first polyimide layer, and a peeling strength between the first and second polyimide layers being less than a peeling strength between the first polyimide layer and the support base so that the second polyimide layer is peelable from the first polyimide layer while the first polyimide layer remains adhered in contact with the support base.

A method of fabricating a flexible printed circuit includes providing a carrying support comprised of a rigid support base and a release layer adhered in contact with each other, forming a flexible substrate on the carrying support, the formed flexible substrate being adhered in contact with the release layer, applying one or more processing step on the flexible substrate while the flexible substrate is supported by the carrying support, and peeling the flexible substrate with an electric circuit formed thereon from the release layer while the release layer remains adhered in contact with the support base.

A material includes a transparent substrate coated with a stack of thin layers including at least one silver-based functional layer, wherein the stack includes a protective coating deposited on top of at least one portion of the functional layer, the protective coating including: a lower protective layer having a thickness of between 1 and 10 nm, a central protective layer based on carbon graphite located on top of the lower protective layer, and an upper protective layer having a thickness of between 1 and 10 nm located on top of the central protective layer.

Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a first central surface area recessed from a first major surface by a first distance and a second central surface area. A second major surface comprises the second central surface area. A blunted edge extends around an entire periphery of the foldable substrate. The blunted edge comprising a first blunted surface area where the blunted edge meets the first major surface and a second blunted surface area where the blunted edge meets the second major surface. Methods comprise laminating the foldable substrate with support layers before removing a peripheral portion of an initial edge of the foldable substrate to form an intermediate edge. The intermediate edge is contacted with an etchant to form the blunted edge. Methods further comprise removing the support layers from the foldable substrate.

A superstrate for forming a planarization layer on a substrate can include a body having a first surface, a second surface opposite the first surface, and a chamfered edge between the first surface and the second surface. An opaque layer can coat the chamfered edge. In another embodiment, an opaque layer can coat the chamfered edge and a portion of the second surface. The superstrate can be used for more planarization or other processing sequences without causing extrusion defects.

A method for obtaining a curved laminated glazing unit, includes applying an enamel coating to a part of a first face of a first glass sheet so as to create at least one enameled zone and at least one unenameled zone, applying a sacrificial layer to a part, called the sacrificial zone, of a first face of a second glass sheet, simultaneously bending the first and second glass sheets, the sacrificial zone being disposed at least in line with at least one part of an enameled zone, removing the sacrificial layer, either during the bending or after the bending step, and laminating the first and second glass sheets by a thermoplastic interlayer.

This disclosure provides systems, methods, and apparatus for tempering or chemically strengthening glass substrates having electrochromic devices fabricated thereon. In one aspect, an electrochromic device is fabricated on a glass substrate. The glass substrate is then tempered or chemically strengthened. The disclosed methods may reduce or prevent potential issues that the electrochromic device may experience during the tempering or the chemical strengthening processes, including the loss of charge carrying ions from the device, redistribution of charge carrying ions in the device, modification of the morphology of materials included in the device, modification of the oxidation state of materials included in the device, and the formation of an interfacial region between the electrochromic layer and the counter electrode layer of the device that impacts the performance of the device.

This disclosure features use of a paper or polymer film that includes a slip agent that can transfer to its surfaces. Once the paper or film is pressed against a glass sheet, this will leave a thin surface roughness of slip agent that can prevent or reduce glass surface scratches from other surfaces or particles during shipping or finishing (e.g., cutting to size, conveyance of glass), thereby improving the yield of glass shipments between glass forming plants and customers. The thin discontinuous layer of slip agent remaining on the glass surface can be washed off easily in subsequent washing processes. The paper or film can have the slip agent imbibed within the paper or coated on it as a surface member.

A method of depositing coating onto both sides of a substrate is provided, which includes steps of upwardly sputtering one or more lower targets to deposit a sacrificial coating onto a second surface and downwardly sputtering one or more upper targets to deposit a first functional coating onto a first surface, washing the substrate with one or more washers to remove the sacrificial coating from the second surface while leaving intact the first functional coating on the first surface, and upwardly sputtering the one or more upper targets to deposit a second functional coating onto the second surface.
