Abstract

The invention discloses a pre-stretched substrate and its manufacturing method, an electronic device and its manufacturing method, and relates to the technical field of substrate pre-stretching. Pre-stretched substrate with a uniform amount of stretch. The manufacturing method of the pre-stretched base comprises: in an environment higher than a preset temperature, sequentially forming at least two film layers on a carrier plate, the thermal expansion coefficients of the at least two film layers are different; At least two film layers are separated from the carrier to obtain a pre-stretched substrate. The manufacturing method of the pre-stretched base provided by the invention is used for manufacturing the pre-stretched base.

Description

technical field [0001] The invention relates to the technical field of substrate pre-stretching, in particular to a pre-stretching substrate and a manufacturing method thereof, an electronic device and a manufacturing method thereof. Background technique [0002] A flexible display is a deformable and bendable display device made of flexible materials. Flexible displays are widely used in various fields due to their low power consumption, diverse display modes, small size, and portability. [0003] In order to ensure the good bending performance of the flexible display, when making the flexible display in the prior art, the flexible material with good deformation ability is usually selected to make the flexible substrate, and then other functional layers are formed on the flexible substrate, so that the flexible display can withstand relatively high pressure. Large bending, stretching or torsional deformations. Moreover, in order to further improve the ability of flexible ...
