An object of the present invention is to provide a chemically strengthened glass plate that is chemically strengthened and thereby increased in strength in its entirety, a portable information terminal using the chemically strengthened glass plate, and a manufacturing method of the a chemically strengthened glass plate. The chemically strengthened glass plate and the manufacturing method thereof according to the present invention is suitable for use in fields of portable information terminals, substrates, etc. in which glass plates having high resistance to impact are required.

Provided is laminated glass and a preparation method thereof, an electronic device housing, and an electronic device. The laminated glass comprises at least two glass members and at least one adhesive film disposed in a stacked manner, where the glass members and the adhesive film are alternately disposed, wherein decorative layers are provided on surfaces of at least two of the glass members facing toward the adhesive film, and at least two of the decorative layers independently comprise at least one of an etched texture, an optical coating layer, and a pattern layer.

A method and an apparatus for embossing a pattern into a varnish on a sheet-like substrate are provided. The method applies a planar stamp using a roller, while the apparatus includes a roller having a planar stamp.

A filamentation process uses ultrafast laser pulses to form a line of filaments or perforations in a glass material in sheet form. The glass material is then cleaved using mechanical or thermal stress to form a glass substrate with a planar doughnut shape having an inner circular edge and an outer circular edge. The inner and outer edges may exhibit filamentary damage from the filamentation process, including microcracks and pillar shaped funnels along an entire length of the edge. The inner and/or outer edges may then be treated by polishing only, by etching only, or by etching and polishing to remove a portion of the filamentary damage to improve the strength of the edges. The resulting glass substrate may be used in a magnetic medium for a magnetic recording device, wherein it provides an edge strength sufficient to withstand high force shocks to the device.

The disclosure provides textured glass components as well as electronic device cover assemblies and enclosures which include the textured glass components. In some cases, a protruding portion of the glass component includes a textured region provided over a camera assembly of the electronic device. One or more openings may be provided in the textured region. The textured region may be configured to provide a translucent or hazy appearance to the electronic device while providing a desirable “feel” to the electronic device and level of cleanability.
