Abstract

The invention discloses a three-dimensional substrate, a manufacturing method thereof and electronic equipment. A to-be-treated plate is placed on a preset mold core, hot-press molding is carried outthrough a hot-press gas with a preset temperature and a preset pressure to form a three-dimensional substrate with a preset graphic structure, a heat insulation plate is arranged at one side, deviating from the mold core, of the to-be-treated plate in the process of gas hot pressing, at least a part of an area, corresponding to the convex curved surface of the mold core, of the to-be-treated plateis exposed out of the heat insulation plate to make the middle part, needing no hot press molding, of the to-be-treated plate isolated through the heat insulation plate, and the middle part is used for being opposite to the top surface of the mold core in the hot press molding process. Heat insulation protection of the middle part, needing no hot-pressing deformation, of the to-be-treated plate through the heat insulation plate can avoid the problem that the middle part wrinkles and warps in the hot-pressing forming process.

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...
