Problems solved by technology

[0002] At present, the base substrates of flexible display devices that can be bent are generally thin glass substrates or plastic substrates. The use of thin glass substrates can achieve a certain degree of bending, but cannot be folded; the use of plastic substrates can be bent and folded, but the stability of plastic Poor performance and mechanical strength, and if figure 1 As shown, due to the poor rigidity of the plastic substrate, the plastic substrate will be bent in the process of manufacturing the flexible display device, resulting in a decrease in the yield of the product. The current solution is to use a glass substrate as the carrier of the plastic substrate in the manufacturing process. After the production is completed, the glass substrate is separated from the plastic substrate, which increases the complexity of the production process and increases the production cost of the product

Embodiment 1

[0040] This embodiment provides a foldable substrate, including:

[0041] Multiple rigid support parts that are independent of each other and do not contact each other;

[0042] A flexible foldable section connecting adjacent rigid support sections.

[0043] The foldable substrate of this embodiment includes a rigid support portion and a flexible foldable portion connecting adjacent rigid support portions. Since the main structure of the foldable substrate is a rigid support portion, there is no problem of deformation during the process. In addition , different rigid support parts are connected by flexible foldable parts, so that bending and folding can be performed at the flexible foldable parts, so that the foldable substrate has both rigidity and foldability.

[0044] The flexible foldable part is made of flexible material, specifically, the flexible foldable part can be made of organic material.

[0045] In order to closely combine the rigid support part and the flexible...

Embodiment 2

[0054] An embodiment of the present invention also provides a flexible display device, including the above-mentioned foldable substrate, and a display device formed on the foldable substrate. The display device may be any product or component with any display function, such as a monitor, a digital photo frame, a mobile phone, and a tablet computer.

Embodiment 3

[0056] This embodiment also provides a method for manufacturing a foldable substrate, including:

[0057] Place multiple hard substrates that are independent of each other and do not touch each other on the carrier substrate;

[0058] Coating a flexible material on the carrier substrate on which the hard substrate is placed, so that the flexible material fills the gap between the hard substrates and can cover all the hard substrates;

[0059] The carrier substrate is separated from the hard substrate and the flexible material to obtain a foldable substrate, wherein the rigid support part of the foldable substrate is composed of the hard substrate and the flexible material covering the hard substrate Composition, the flexible foldable part of the foldable substrate is composed of flexible material between rigid substrates.

[0060] The foldable substrate produced in this embodiment includes a rigid support part and a flexible foldable part connecting adjacent rigid support par...
