The at least one elevated region comprises a further glass composition. An exterior diameter of the hollow body has a maximum throughout the contact range. The at least one surface region is at least partially positioned in the at least one contact region.

A flexible display device includes a flexible display panel bendable along a bending axis. A support backplate is disposed on a side of the flexible display panel and located on an outer side of the flexible display panel when bending. The support backplate includes a support area and a plurality of extension areas defined on opposite sides of the bending axis and adjoining two sides of the support area. When the flexible display device is in an expanded state, a difference value between a length of the support backplate and a length of the flexible display panel in a direction perpendicular to the bending axis is greater than or equal to a first threshold. The flexible display device can reduce the risk of peeling of components in a bent state and can ensure a product lifespan.

A bonding structure includes a substrate, a first sensing electrode layer, a second sensing electrode layer, an optical film layer, and a protective layer. The substrate has opposite first and second surfaces. A sensing area and a bonding area are defined on the substrate. The first sensing electrode layer is disposed on the first surface.

Aspects herein are directed to systems, methods, and articles for producing a patterned film and using the patterned film to form a pattern of discrete overlay film structures on a substrate material. A uniform thickness of a film material is deposited on to a first surface of a run of carrier sheets, where each carrier sheet includes one or more holes extending there through. A first carrier sheet is extracted from the run of carrier sheets, and a second surface of the carrier sheet is positioned on a substrate material. Heat and/or pressure is applied to the film material to cause the film material to transfer to the substrate material through the one or more holes in the carrier sheet forming a pattern of discrete overlay film structures on the substrate material. The carrier sheet along with remaining portions of the film material is removed from the substrate material.

A method of making a multi-layer product or seal is described. An adhesive layer is applied to a surface of a first layer. A patch material is applied to a surface of the adhesive layer, using a coating or spraying process, to define one or more patches. At least the first layer is cut to define pre-formed lines of separation defining one or more first portions. Each first portion is associated with a respective one of the one or more patches.

Embodiments of an article comprising a cold-formed glass substrate in a curved shape, a plurality of separate mechanical retainers, and a frame are disclosed. The cold-formed glass substrate has a first major surface, and a second major surface opposing the first major surface.

A conductive yarn pressure sensor is proposed. The pressure sensor may include a porous fiber layer having predetermined cavities formed therein. The pressure sensor may also include a first sensing electrode made of a first conductive yarn formed on one surface of the porous fiber layer, and a second sensing electrode made of a second conductive yarn formed on the other surface of the porous fiber layer. The first sensing electrode or the second sensing electrode may be provided so as to be in contact with each other in the cavities of the porous fiber layer due to external pressure. According to an embodiment, by having conductive yarn in flexible clothing or textile material, pressure can be sensed by effectively responding to deformation due to external pressure.
