An object of the present invention is to provide a chemically strengthened glass that can effectively suppress strength of a glass from being deteriorated even though performing chemical strengthening and has high transmittance (that is, low reflectivity). The present invention relates to a chemically strengthened glass having a compressive stress layer formed on a surface layer thereof by an ion exchange method, in which the glass contains sodium and boron, and has a delta transmittance being +0.1% or more, and in which a straight line obtained by a linear approximation of a hydrogen concentration Y in a region of a depth X from an outermost surface of the glass satisfies a specific relational equation in X=0.1 to 0.4 (μm).

The present invention provides an UV cleaning device of a glass substrate, comprising a lamp box, an UV lamp positioned above inside the lamp box, a transparent shield positioned under the UV lamp, a humidifier positioned under the transparent shield and a power exhaust device under the transparent shield and opposite to the humidifier; in usage, the glass substrate is conveyed to be inside the lamp box, and UV light generated by the UV lamp irradiates on the glass substrate through the shield to clean the glass substrate and a humidity and an oxygen content inside the lamp box are adjusted with the humidifier to make a surface of the glass substrate adsorb one layer of water molecules. The electrons generated as the UV light cleans can be gradually conducted and led out with water molecules to effectively restrain the accumulation of the electrostatic to reduce the phenomenon of electrostatic damage, and meanwhile, the increase of the oxygen content makes the concentration of the activated oxygen atoms increases along with. Accordingly, the result of cleaning the organic objects with the UV light is promoted.

A method of manufacturing a cover window for a display device includes: providing a glass substrate having a bendable area and a flat area; modifying the bendable area by irradiating the glass substrate with a beam; and etching the bendable area to have a thinner thickness than the flat area. The bendable area may have a faster etch rate than the flat area due to the modifying of the bendable area.

A method for producing reinforced glass, reinforced glass and an electronic device are provided. The method for producing reinforced glass includes: subjecting glass to a first reinforcing treatment; detecting a first stress parameter of the glass subjected to the first reinforcing treatment, and determining whether the glass subjected to the first reinforcing treatment is qualified according to the first stress parameter; subjecting the glass to a second reinforcing treatment when the glass subjected to the first reinforcing treatment is qualified; detecting a second stress parameter of the glass subjected to the second reinforcing treatment, and determining whether the glass subjected to the second reinforcing treatment is qualified according to the second stress parameter; and subjecting the glass to a touch-polishing treatment when the glass subjected to the second reinforcing treatment is qualified, so as to obtain the reinforced glass.

A glass treatment apparatus comprises an upstream applicator comprising a first surface. The first surface is movable between a first upstream position where the first surface is within a travel path of the glass treatment apparatus while extending across a travel direction of the travel path and facing a downstream direction opposite the travel direction, and a second upstream position where the first surface is outside the travel path. Additionally, methods of treating a glass ribbon with the glass treatment apparatus are disclosed.

A coated glass element includes: a glass surface and a coating that coats at least part of the glass surface. The coating has at least one layer.

[Al.sup.+].sub.20 are counts of [Al.sup.+] ions, measured by a time-of-flight secondary ion mass spectrometry (TOF-SIMS), at 20% of a time a sputter gun beam needs to reach the glass surface and [Al.sup.+].sub.80 are counts of [Al.sup.+] ions, measured by a TOF-SIMS, at 80% of a time a sputter gun beam needs to reach the glass surface.

The present disclosure includes a method of making an article including etching a surface of a substrate with an etching suspension comprising an etching cream and glycerin, such that the surface is an anti-glare surface and the article comprises a sparkle of no more than 1%. An article made by the method can include a substrate having a textured surface and comprises a sparkle of no more than 1%.

An inorganic substrate with an improved via shape and methods for facilitating formation of such improved via shape are disclosed. A double-sided opening process may be applied to an inorganic substrate to form openings at the ends of a damage track previously formed in the inorganic substrate. One side of the inorganic substrate may then be sealed, such as by being temporarily bonded to a carrier or blocking substrate, so that a single-sided opening process may be applied to the other unsealed or unblocked surface of the inorganic substrate. The single-sided opening process may enlarge at least one of the openings formed by the double-sided opening process and may enlarge a channel between the openings to form a via having an advantageous shape.
