Embodiment Construction

[0062] In order to further illustrate the pre-stretched substrate and its manufacturing method provided by the embodiments of the present invention, the electronic device and its manufacturing method, the detailed description will be described below in conjunction with the accompanying drawings.

[0063] The manufacturing method of the pre-stretched base provided by the embodiment of the present invention comprises:

[0064] In an environment higher than a preset temperature, at least two film layers are sequentially formed on the carrier plate, and the thermal expansion coefficients of the at least two film layers are different;

[0065] Specifically, the above-mentioned preset temperature can be selected as normal temperature, for example: 25° C., the temperature in the environment higher than the preset temperature can be set according to the thermal expansion coefficients of at least two film layers to be actually produced, for example: it can be set higher than The temper...

Abstract

The invention discloses a pre-stretching base and a manufacture method thereof and an electron device and a manufacture method thereof, and relates to the technical field of base pre-stretching. In order to solve the problem that an existing pre-stretching base manufacture method can not form the pre-stretching base with a large area and even pre-stretching quantities, the manufacture method of the pre-stretching base includes the following steps that under the environment with temperature high than preset temperature, at least two layers of films are successively formed on a carrier plate, and thermal expansivity coefficients of the at least two layers of films are different; and the at least two layers of films are separated from the carrier plate, and the pre-stretching base is obtained. The manufacture method of the pre-stretching base is used for manufacturing the pre-stretching 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 deformation. Moreover, in order to further improve the ability of flexible d...
