Abstract

The application discloses a three-dimensional substrate and its manufacturing method as well as electronic equipment. The technical proposal of the application places the plate to be processed on a set mold core, and performs hot-press molding with hot-pressed gas at a set temperature and pressure to form a preset For a three-dimensional substrate with a graphic structure, during the process of gas hot pressing, a heat shield is placed on the side of the plate to be treated away from the mold core, and the heat shield at least exposes the plate to be treated corresponding to the Partial area of ​​the convex surface of the mold core, so that the middle part of the plate to be processed can be isolated without thermocompression forming by the heat insulating plate, and the middle part is used for contact with the mold core during the thermocompression forming process. The top faces are opposite. The middle part of the plate to be processed that does not need to be deformed by hot pressing is protected by heat insulation through the heat insulating board, so that the problem of wrinkling and warping of the middle part during the hot pressing forming process can be avoided.

Description

technical field [0001] The present application relates to the technical field of hot pressing technology, and more specifically, relates to a three-dimensional substrate, a manufacturing method thereof, and an electronic device. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable essential tool. [0003] Conventional electronic devices are generally flat display devices, and generally need to be provided with a two-dimensional flat transparent cover on the display side. Conventional cover plates are generally glass cover plates. However, with the wide application of curved display devices, if a three-dimensional substrate made of glass is used as a cover plate of the curved display device, the manufacturing cost is high and the strength is...
