The present invention discloses a extrusion forming method and a forming apparatus for manufacturing a self-clinching rivet, wherein the forming method comprises: upset-extruding a first end of a wire blank to shape it into a material pushing portion and a shank portion billet, upset-extruding the shank portion billet to shape it into a shank portion and a groove portion, and upset-extruding a second end of the wire blank to create a slot portion and a slot shaft portion. The invention for manufacturing the self-clinching rivet by one-time extrusion forming does not generate waste during processing, which greatly improves a utilization rate of raw materials compared with the traditional machining method. Meanwhile, a formed piece manufactured by the present invention has complete metal streamlines, which can greatly improve its strength compared with the one manufactured by machining and avoid a risk of hydrogen embrittlement in a subsequent surface treatment.

Extrusion molding method and molding apparatus for manufacturing self-clinching rivet

Included are flexible display panels, manufacturing methods thereof and flexible display apparatuses, which are used to solve the problem of poor conductive function of wires in a bending area. The flexible display panel includes a display area and a bending area located around the display area, where the bending area includes: a flexible substrate; an adjustment layer covering the entire flexible substrate; a protective layer located on the adjustment layer; a plurality of wires located on the protective layer; and a planarization layer located above the wires and covering a functional film layer on the flexible substrate; where the protective layer corresponds to the wires in the bending area, and an orthographic projection of the wires in the bending area on the flexible substrate falls into an orthographic projection of the protective layer on the flexible substrate.

Flexible display panels, manufacturing methods thereof and flexible display apparatuses

The present disclosure relates to a composite substrate adapted for manufacturing a flexible display screen. The composite substrate includes a base substrate, a sacrificial layer, and a flexible layer. The sacrificial layer is located on the base substrate. The flexible layer is located on the sacrificial layer. The sacrificial layer is an inorganic layer which contains hydrogen element and is semi-transparent. The present disclosure further provides a method for manufacturing a flexible display screen, comprising: depositing a sacrificial layer on a base substrate, the sacrificial layer is an inorganic layer, the inorganic layer contains hydrogen element and is semi-transparent; forming a flexible layer on the sacrificial layer; forming electronic components on the flexible layer; and irradiating the sacrificial layer by a laser beam to cause the hydrogen element in the sacrificial layer to form hydrogen gas bubbles, so as to separate the base substrate and the sacrificial layer.

Manufacturing methods for flexible display screens and composite substrates for flexible display screens

An array substrate, a display panel and a manufacturing method for the array substrate. An array substrate includes: a flexible substrate having a display area and a bending area; a barrier layer continuously laid on the flexible substrate, where a thickness of the barrier layer above the bending area is less than half of a thickness of the barrier layer above the display area; and a wiring layer laid directly above the barrier layer located in the bending area.
