Embodiment 1

[0032] This embodiment provides an elastically deformable display substrate, such as figure 1 As shown, it includes a plurality of display devices 4 and a deformable layer 3 made of elastic material, wherein the first side of the deformable layer 3 is provided with a plurality of first protrusions 1, and the first side of the deformable layer 3 A plurality of second protrusions 2 are arranged on two sides, and the display device 4 is disposed on a side of the first protrusion 1 away from the deformable layer 3 .

[0033] The deformable layer 3 of the display substrate in this embodiment is stretched when subjected to a force, and when different materials are selected according to different needs, the deformable layer 3 can resume deformation after the force disappears. Wherein, the plurality of first protrusions 1 on the first side of the deformable layer 3 and the display device 4 on the first protrusions 1 can also be referred to as an interconnected island structure, and th...

Embodiment 2

[0035] This embodiment provides an elastically deformable display substrate, such as figure 2 As shown, it includes a plurality of display devices 4 and a deformable layer 3, wherein the first side of the deformable layer 3 is provided with a plurality of first protrusions 1, and the second side of the deformable layer 3 is provided with a plurality of a second protrusion 2, the display device 4 is arranged on the side of the first protrusion 1 away from the deformable layer 3, and a plurality of the first protrusions 1 and a plurality of the second protrusions 2 are deformable The two sides of layer 3 are arranged symmetrically.

[0036] In this embodiment, the position where the first protrusion 1 is provided on one side of the deformable layer 3 corresponds to the second protrusion 2 at the same position on the other side, and the structure of the second protrusion 2 and the first protrusion 1 , the same size, and the two are in a symmetrical state with the deformable lay...

Embodiment 3

[0053] This embodiment provides a method for preparing an elastically deformable display substrate, such as Figure 9 shown, including the following steps:

[0054] S01. Prepare a first substrate 31 with a plurality of first protrusions 1, the first substrate 31 is made of a deformable material; a method for preparing a first substrate with a plurality of first protrusions 1 is provided here 31 specific method:

[0055] S01a, providing a carrier 6 with a plurality of recesses, the carrier 6 can be made of glass or metal plate or other materials;

[0056] S01b, coating a deformable material on the side of the carrier 6 having a concave portion; specifically, in this embodiment, the deformable material is composed of polydimethylsiloxane (PDMS);

[0057] S01c. After the deformable material is solidified into a film, it is peeled off from the carrier 6 to obtain a first substrate 31 having a plurality of first protrusions 1 .

[0058] S02 , forming a display device 4 on a side...

Abstract

The invention provides an elastically deformable display substrate, a preparation method thereof and a display device, belongs to the technical field of flexible display and can solve the problem thatthe normal display is influenced by the fact that conventional display devices extend and deform to a certain degree with stretching of the substrates. A plurality of first bulges on the first side of a deformable layer of the display substrate and display devices on the first bulges can also be called an interconnection island structure, and second bulges are further arranged on a second side ofthe deformable layer and used for relieving and dispersing stress of the first bulges on the deformable layer. Therefore, normal display affected by damage of contact surfaces between the display devices and the first bulges due to stress on the first bulges is effectively prevented, that is, the display devices can display normally whether in the stressed stretching state, the unstressed state or the deformation restored state by means of the second bulges. The display substrate is suitable for various display devices.

Description

technical field [0001] The invention belongs to the technical field of flexible display, and in particular relates to an elastically deformable display substrate, a preparation method thereof, and a display device. Background technique [0002] In the prior art, the requirements for display products are getting higher and higher. In order to meet application requirements such as wearable display products, stretchable display devices have been widely discussed and paid attention to. [0003] The inventors have found that there are at least the following problems in the prior art: the current products generally make multiple display devices on a stretchable substrate, however, the display devices will inevitably stretch to a certain extent with the stretching of the substrate, Deformation, the extension and deformation of the display device will affect the normal display of the display device. Contents of the invention [0004] Aiming at the problem that the existing displa...
