An organic light emitting diode display device and a display apparatus, and a mask for fabricating a sub-pixel of the organic light emitting diode display device are provided. Each pixel unit group includes a first sub-pixel unit group and a second sub-pixel unit group which are disposed adjacently along a first direction and include three sub-pixels of different colors, respectively; and the three sub-pixels in the first sub-pixel unit group and the three sub-pixels in the second sub-pixel unit group are staggered along a second direction, and a color of any sub-pixel on a base substrate is different from a color of any other sub-pixel adjacent to the sub-pixel.

Electronic equipment may include structured fabric. Structured fabric may be used as a protective case or cosmetic cover for an electronic device, may be used to form a band that holds an electronic device against a user's body, or may be used to cover one or more openings in an electronic device. Structured fabrics may be soft and pliable while maintaining the ability to hold a given shape without added support. Structured fabric may be formed by laminating fabric such as warp-knit fabric with a stiffener such as polymer film. Structured fabrics may include openings through which signals such as optical or audio signals pass. To maintain the geometry and shape of the openings in the structured fabric without covering the openings, the stiffener and adhesive that are attached to the fabric may be cut to form a pattern of openings that align with the openings in the fabric.

A backing sheet for use in a wound dressing, comprising a semipermeable continuous film laminated to an adhesive-coated apertured layer, wherein the apertured layer comprises a solid substrate coated with a medically acceptable adhesive. Also provided is a method of making a backing sheet for use in a wound dressing, said method comprising the steps of: forming an adhesive-coated apertured layer by coating a medically acceptable adhesive onto an apertured solid substrate, followed by laminating the adhesive-coated apertured layer to a semipermeable continuous film.

A hierarchical sandwich core in the form of a honeycomb, i.e. having repetitive and periodic lattice materials. The sandwich core can be made up of a macroscopic honeycomb structure with sandwich cell walls having a mesoscopic cellular core. The longitudinal axis of cells of the mesoscopic honeycomb cell can be perpendicular to the longitudinal axis of the cells of the macroscopic honeycomb structure. Alternatively, if a foam core is used having mesoscopic cells the shape of the mesoscopic cells can be made during the foaming process so that they are elongate in a direction perpendicular to the longitudinal axis of the cells of the macroscopic honeycomb structure.

A cushioning wrap material includes an elongate layer of expanded sheet material comprising an array of openings, and an elongate layer of interleaf material secured to the layer of expanded sheet material in face-to-face relationship. The expanded sheet material is expanded in length and thickness, and the layer of interleaf material may have a width equal to or less than a width of the layer of expanded sheet material. Typically, the layer of interleaf material is secured to the layer of expanded sheet material such that respective longitudinal centerlines of each layer are substantially aligned. The layer of expanded sheet material and layer of interleaf material secured thereto are then wound into a roll. Typically, each layer is at least thirty feet in length.

An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.

A method for enhancing sorption performance of a sorbent material includes the step of increasing a surface area of the sorbent material for adsorption of a fluid at an interface between the fluid and the sorbent material by arranging one or more apertures to be disposed on the sorbent material, wherein each of the one or more apertures is further arranged to define an interior space for absorption of the fluid.

A laminate of an at least partially reticulated thermoplastic film joined to an extensible carrier. The reticulated thermoplastic film includes a backing with openings and discrete elements protruding from the first major surface. There are two discrete elements aligned in a first direction abutting opposite ends of any given opening. In a second direction perpendicular to the first direction, there is one discrete element between the given opening and an adjacent opening aligned in the second direction. Each portion of the thermoplastic backing around the given opening is plastically deformed in its lengthwise direction. A method of making a laminate is also disclosed. The method includes stretching a thermoplastic backing having a plurality of discrete elements in the first direction and laminating the backing to an extensible carrier. Subsequently stretching the laminate in a second direction forms a tear in the thermoplastic backing between two adjacent of the discrete elements.

An article of apparel includes a base layer and an auxetic layer. The base layer includes a four way stretch material. The auxetic layer is coupled to the base layer and includes an auxetic structure defining a repeating pattern of voids. The base layer is exposed by at least one void of the auxetic layer.
