Abstract: Electronic devices may be provided with display structures such as glass and polymer layers in a liquid crystal display. The glass layers may serve as substrates for components such as a color filter layer and thin-film transistor layer. The polymer layers may include films such as a polarizer film and other optical films. During fabrication of a display, the polymer layers and glass layers may be laminated to one another. Portions of the polymer layers may extend past the edges of the glass layers. Laser cutting techniques may be used to trim away excess portions of the polymer layer that do not overlap underlying portions of the glass layers. Laser cutting may involve application of an adjustable infrared laser beam.

Abstract: This invention provides an enhanced condensation heat-transfer tube, which is furnished with spiral fins on the outer surface. Axial spacing between the said fins regularly changes in width. In a preferred embodiment, the said fins regularly change in height along the axle. Such spiral fins with even changes in height and spacing change the surface tension of the condensate membrane between the fins outside of the tube, so as to enhance the “Gregorig” effect (average heat resistance reduces due to uneven thickness of condensate membranes). In this way, it further strengthens condensation heat transfer effects outside of the tube. At the same time, it accelerates flowing of the condensate to the bottom, enhances heat transfer effect, and improves the tube bundle effect.

Abstract: Structures such as display structures and other electronic device structures may be shaped using water jet cutting equipment. The water jet cutting equipment may be used to produce a water jet. The water jet may be used to cut layer of material such as display layers and other structures. Water jet cutting may form edge cuts, cuts for openings in the structures, chamfers, and other features. Multiple layers may be simultaneously cut using water jet cutting. Positioning equipment may be used to control the position of a workpiece relative to a water jet nozzle. The positioning equipment may be controlled using a control unit. During water jet cutting operations, the workpiece may be trimmed, openings may be formed, and features such as chamfers may be created. A workpiece may include a cover glass, a color filter array, a thin-film transistor layer, and other display layers and device structures.

Abstract: Layers of material such as glass layers for displays may be cut using scribing and breaking techniques. Scribing-and-breaking equipment may include a scribe tip that forms a loop-shaped scribe line in the surface of a layer of material. The loop-shaped scribe line may have a rectangular shape with four straight sides and four rounded corners. A breaking structure such as a rectangular ring-shaped metal break frame with rounded corners may be configured to match the shape of the scribe line. During breaking operations, the layer of material may be supported on a support structure. The support structure may have a flexible material such as an elastomer and a lower-friction coating layer such as a polytetrafluoroethylene coating. The break frame may be aligned with the scribe line and may be used to press down on the layer of material, thereby breaking the layer of material along the scribe line.
