The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present application discloses a display screen body, including:
the display screen comprises a glass substrate and a display layer group 12 prepared on the glass substrate, wherein a bendable region 10 is arranged on the display layer group 12, the glass substrate below the bendable region 10 is removed, and the bendability of the bendable region 10 of the display screen body is improved. After the glass substrate under the bendable region 10 is removed, the glass substrate is divided into two parts, a glass substrate 111 and a glass substrate 112.
Referring to fig. 2, the display layer group 12 includes a flexible substrate 121 and a functional layer 122. The flexible substrate 121 is located over a glass substrate. In the embodiment, the flexible substrate 121 may be made of any one of Polyimide (PI), polyethylene naphthalate (PEN), Polycarbonate (PC), polyethylene terephthalate (PET), and polyether sulfone (PES). The thickness of the flexible substrate 121 may be 18-20 μm (may be, but is not limited to, 18 μm, 19 μm, or 20 μm). The flexible substrate 121 covers the glass substrate before the portion below the bendable region is removed (i.e., the flexible substrate covers the glass substrate 111, the glass substrate 112 and the bendable portion 10) to provide a hardware basis for the bendability of the bendable portion 10 of the display panel body. The functional layer 122 is located on the flexible substrate 121, and the functional layer 122 may include a cathode, an anode, a circuit structure and a light emitting device, so as to provide a circuit and a device as a light emitting property of the display panel body.
In the embodiment of the present application, referring specifically to fig. 3, the display panel body further includes a glass cover plate covering an upper surface of a region (a region where the display panel is not bendable) of the display layer group other than the bendable region 10, the glass cover plate 131 covers the upper surface of the display layer group on one side of the bendable region 10, and the glass cover plate 132 is disposed on an upper surface of the other side of the bendable region 10 of the display layer group. That is, a portion of the display layer group corresponding to the bendable portion is exposed. In the present embodiment, the transparent cover plates 131, 132 are transparent glass cover plates or transparent polymer cover plates. In the embodiment of the present application, the thickness of the transparent cover plate is not limited, and may be the same as or different from the thickness of the glass substrate 11, for example.
In the embodiment of the present application, referring to fig. 4, the display screen body further includes a first elastic layer 141 and a second elastic layer 142, where the first elastic layer 141 is located on an upper surface of the bendable region of the display layer group 12; and the second elastic layer 142 is located on the lower surface of the bendable region of the display layer group (i.e., the surface of the display layer group 12 contacting the glass substrate 11). The material of the first elastic layer 141 and the material of the second elastic layer 142 may be the same or different, and is not limited herein. For example, the first elastic layer and the second elastic layer may be made of rubber, one of the first elastic layer and the second elastic layer may be made of rubber, or both of the first elastic layer and the second elastic layer may not be made of rubber. In the present embodiment, the bendable region 10, the first elastic layer 141 and the second elastic layer 142 form the bendable portion 15 of the display panel.
The materials of the first elastic layer 141 and the second elastic layer 142 are explained above, and the magnitude relationship between the thickness of the first elastic layer 141 and the thickness of the second elastic layer 142 is explained here. In the embodiment of the present application, it is preferable that the thickness of the first elastic layer 141 is not greater than that of the transparent cover plate, and accordingly, the thickness of the second elastic layer 142 is not greater than that of the glass substrate. The thickness of the first elastic layer 141 and the thickness of the second elastic layer 142 may be equal or different, and is not limited herein. In a specific embodiment, the thickness of the first elastic layer 141 may be: 1-1000 μm, but may be, but is not limited to, 1 μm, 500 μm, or 1000 μm. In another specific embodiment, the thickness of the second elastic layer 142 may be 1-1000 μm, and may be, but is not limited to, 1 μm, 500 μm, or 1000 μm: the applicant has found that the first elastic layer 141 and the second elastic layer 142 having such thickness ranges can protect the functional layer and can relieve the bending stress of the functional layer 122 during the bending process, thereby increasing the number of times the display panel is bent.
It should be understood that, in the embodiment of the present application, one bendable region 10 is disposed in the display layer group 12, and it is noted that, one bendable region 10 is only disposed for describing the flexibility of the display screen body, and the number of the bendable portions 15 of the display screen body is not limited, and a plurality of bendable regions 10 may be disposed in the display layer group according to actual requirements, so as to form a plurality of bendable portions 15 of the display screen body.
In the embodiment of the present application, the display layer set may include a bendable region 10 (i.e., the display screen body includes a bendable portion 15), and the first elastic layer 141 is made of a transparent material so as to transmit light emitted by the display layer set. The bending angle of the bendable region of the display layer group is 0-360 degrees, and correspondingly, the bending angle of the bendable portion 15 of the display screen body can be 0-360 degrees. When the bending angle is 0 to 180 degrees, the compression resistance of the first elastic layer 141 is greater than that of the second elastic layer 142; the stretch-resistant property of the second elastic layer 142 is preferably greater than that of the first elastic layer 141. In this way, when the display body is bent only within 180 degrees and the functional layers are folded against each other (e.g., forming a "U" shaped flexible display), the number of times the display body is bent can be greatly increased, since the first elastic layer 141 will be compressed and the second elastic layer 142 will be stretched. In a preferred embodiment, the material of the first elastic layer 141 is rigid polyvinyl chloride, and the material of the second elastic layer 142 is natural rubber or butadiene rubber.
When the bending angle is 180-360 degrees, it is preferable that the stretch resistance of the first elastic layer 141 is greater than the stretch resistance of the second elastic layer 142, and the compression resistance of the second elastic layer 142 may be greater than the stretch resistance of the first elastic layer 141. In this way, when the display screen body is bent only within 180-. In a preferred embodiment, the material of the second elastic layer 142 is rigid polyvinyl chloride, and the material of the first elastic layer 141 is natural rubber or butadiene rubber.
In the embodiment of the present application, the display layer set may include a plurality of bendable regions 10, the bending angle of which is 0-360 degrees, and accordingly, the display screen body includes a plurality of bendable portions 15, when the plurality of bendable portions 15 of the display screen body need to be bent according to a certain requirement, if a "wave" shape is formed, a portion of the first elastic layer of the bendable portion 15 is stretched, and another portion of the first elastic layer of the bendable portion 15 is compressed. Accordingly, the second elastic layer corresponding to the stretched first elastic layer is compressed, and the second elastic layer corresponding to the compressed first elastic layer is stretched. Therefore, in the case of manufacturing a display panel body including a plurality of bendable portions, it is preferable to set the stretch resistance of the first elastic layer to be the same as that of the second elastic layer, and also set the compression resistance of the first elastic layer to be the same as that of the second elastic layer. Therefore, the bending times of the display screen body can be greatly improved. To meet this requirement, the first elastic layer and the second elastic layer may be made of the same material, for example, rubber may be used to make the first elastic layer and the second elastic layer, respectively.
In the embodiment of the present application, the width of the bendable region is: 1-10mm, but may be, but is not limited to, 1mm, 5mm, or 10 mm.
The display screen body disclosed by the embodiment of the application comprises a glass substrate and a display layer group prepared on the glass substrate, wherein the glass substrate below a bendable region of the display layer group is removed, and the glass substrate below a non-bendable region of the display layer group is used for improving the hardness of the display screen body. The display screen body that this technical scheme provided, including bendable part and the part of can not buckling, can satisfy user's demand to a great extent.
In addition, according to the display screen body provided by the embodiment of the application, the glass substrate is directly adopted to enhance the hardness of the non-bendable part, instead of manufacturing a thick flexible substrate to ensure the hardness of the non-bendable region, so that the waste of materials of the flexible substrate is avoided.

step S11, providing a glass substrate, and preparing a flexible display layer group on the glass substrate;
first, a glass substrate 11 is provided, and in the embodiment of the present application, the thickness of the glass substrate 11 may be greater than 500 μm. The glass substrate 11 has a high hardness, and therefore, the preparation of the display layer group 12 on the glass substrate 11 has high feasibility of implementation.
In the embodiment of the present application, referring to fig. 6, the step of preparing a flexible display layer group 12 on the glass substrate 11 includes:
s111, preparing a flexible substrate on the glass substrate to provide a hardware basis for the flexibility of the display screen body;
in one embodiment, a specific method for preparing the flexible substrate 121 on the glass substrate 11 may be: a layer of flexible material is spin-coated on the upper surface of the glass substrate 11, and then the spin-coated flexible material is cured through a curing process to form the flexible substrate 121. It is also possible to choose an already cured flexible substrate layer with an adhesive layer by means of which the flexible substrate layer is adhered to the upper surface of the glass substrate. The flexible substrate 121 can be prepared using either of the above-described two methods. In one embodiment, the thickness of the prepared flexible substrate may be 5 μm to 125 μm, and may be, but is not limited to, 5 μm, 65 μm, or 125 μm.

In this application, the surface of the flexible substrate 121 to which the functional layer 122 is bonded is an upper surface of the flexible substrate 121, and the surface of the flexible substrate 121 to which the glass substrate 11 is bonded is a lower surface; meanwhile, the direction of the upper surface of the flexible substrate 121 with respect to the flexible substrate is defined as "upper", and the direction of the lower surface of the flexible substrate 122 with respect to the flexible substrate 11 is defined as "lower". The upper and lower surfaces and the upper and lower surfaces of the flexible substrate 121 are described herein for convenience of description only and are not intended to be limiting.
It is to be understood that during the preparation of the above described functional layer 122, the cathode, anode, circuit structure and light emitting device can be fabricated in the functional layer.

The bendable region 10 is selected on the display layer group 12 according to the requirement, so that the display layer group includes the bendable region 10 and the non-bendable region (the region of the display screen body except the bendable region 10), accordingly, the bendable portion of the display screen body is obtained according to the bendable region 10 of the display layer group, and the non-bendable portion of the display screen body is obtained according to the non-bendable portion of the display layer group. The width of the bendable region 10 is 1mm-10mm, but may be, but is not limited to, 1mm, 5mm, or 10 mm. Due to the non-bendability of the glass substrate, the glass substrate on the lower surface of the bendable region 10 needs to be removed, so that the screen body can be bent by means of the bendable region 10.
As for the method of removing the portion of the glass substrate on the lower surface of the bendable region 10, the embodiment of the present application may adopt one of the following methods:
1) an etching method is adopted. Before etching, a photoresist layer is first formed on an appropriate region of the lower surface of the glass substrate 11, and then the glass substrate 11 is etched under the protection of the photoresist layer. After etching, the photoresist layer is removed.
2) A mechanical cutting method is adopted.
3) The laser cutting method is adopted.
It should be noted that, in the embodiment of the present application, portions of the glass substrate other than the bendable portion 10 (e.g., portions shown by reference numerals 111 and 112) are not removed. These unremoved portions 111, 112 of the glass substrate serve to increase the stiffness of the non-bendable portions of the display body.
In an embodiment of the present application, the method further includes:

the method comprises the following steps: firstly, a transparent cover plate is attached to the upper surface of the display layer group 12 in a covering mode; then, coating a photoresist layer on the upper surface of the transparent cover plate; next, removing the transparent cover plate on the upper surface of the bendable region by using an etching method; and finally, removing the redundant photoresist. Thus, the transparent cover 131 and the transparent cover 132 are formed.
In the second method, the transparent cover plate 131 is attached to the left side of the bendable region of the display layer group 12 in an overlaying manner, and the transparent cover plate 132 is attached to the right side of the bendable region of the functional layer in an overlaying manner.
In step S17, elastic layers are formed on the upper surface and the lower surface of the bendable region 10 of the display layer group 12, respectively.
In the embodiment of the present application, the first elastic layer 141 is formed on the upper surface of the bendable region 10 in a covering manner, and the second elastic layer 142 is formed on the lower surface of the bendable region 10 in a covering manner. In this way, the elastic layer (including the first elastic layer 141 and the second elastic layer 142) and the display layer group of the bendable region corresponding to the elastic layer constitute the bendable portion 15 of the display panel body.
Preparing a first elastic layer 141 to cover the upper surface of the bendable region 10 of the display layer group 12, preparing a second elastic layer 142 to cover the lower surface of the bendable region 10 of the display layer group 12, wherein the first elastic layer 141 and the second elastic layer 142 are used for improving the flexibility of the bendable portion 15 of the display screen body corresponding to the bendable region 10.
The first elastic layer 141 is covered on the upper surface of the bendable region of the functional layer 122. The first elastic layer 141 is closely attached to the transparent cover plates (the transparent cover plate 131 and the transparent cover plate 132) on both sides thereof. In one embodiment, the first elastic layer 141 is made of an elastic material, such as rubber. The lower surface of the portion of the flexible substrate corresponding to the bendable region is covered with a second elastic layer 142. The second elastic layer 142 is closely attached to the glass substrates (the glass substrate 111 and the glass substrate 112) on both sides thereof. The second elastic layer 142 is made of an elastic material, such as rubber. It is noted that the material of the first elastic layer 141 and the material of the second elastic layer 142 may be the same or different, and is not limited herein.
The materials of the first elastic layer and the second elastic layer are described above, and the thicknesses of the first elastic layer and the second elastic layer are explained here. The thicknesses of the first and second elastic layers are not in a fixed relationship, that is, the thickness of the first elastic layer is greater than that of the second elastic layer, the thickness of the second elastic layer is greater than that of the first elastic layer, and even the thicknesses of the first and second elastic layers are the same, which is not limited herein. In the embodiment of the present application, it is preferable that the thickness of the first elastic layer is not greater than that of the transparent cover plate, and it is preferable that the thickness of the second elastic layer is not greater than that of the glass substrate.
In the embodiment of the present application, the first elastic layer is transparent to ensure that the light emitted from the display layer group is completely transmitted. When the display screen body with the bendable region is prepared by the method provided by the embodiment of the application and the bending angle is 0-180 degrees, the compression resistance of the first elastic layer 141 is preferably greater than that of the second elastic layer 142 when the first elastic layer 141 and the second elastic layer 142 are manufactured; the stretch-resistant property of the second elastic layer 142 is preferably greater than that of the first elastic layer 141. In this way, when the display body is bent only within 180 degrees and the functional layers are folded against each other (e.g., forming a "U" shaped flexible display), the number of times the display body is bent can be greatly increased, since the first elastic layer 141 will be compressed and the second elastic layer 142 will be stretched. In a preferred embodiment, the material of the first elastic layer 141 is acrylonitrile butadiene styrene copolymer and the material of the second elastic layer 142 is polyethylene. Acrylonitrile is light ivory and polyethylene is colorless, and both are transparent at relatively thin thicknesses, e.g., on the order of microns.
When the method provided by the embodiment of the application is used for preparing the display screen body with the bendable region, and the bending angle is 180-360 degrees, when the first elastic layer 141 and the second elastic layer 142 are manufactured, the stretch resistance of the first elastic layer 141 is preferably greater than that of the second elastic layer 142; the compression resistance of the second elastic layer 142 is preferably greater than that of the first elastic layer 141. In this way, when the display screen body is bent only within 180-. In a preferred embodiment, the material of the first elastic layer 141 is polyethylene and the material of the second elastic layer 142 is acrylonitrile-butadiene-styrene copolymer. Acrylonitrile is light ivory and polyethylene is colorless, and both are transparent at relatively thin thicknesses, e.g., on the order of microns. And the thickness of the first elastic layer is 1-1000 μm, so that no matter the first elastic layer is made of acrylonitrile or polyethylene, the first elastic layer is transparent under the micron-sized condition, and the light emitted by the display layer group can be effectively ensured to be completely transmitted.
When the display screen body with the plurality of bendable parts is prepared by the method provided by the embodiment of the application, each prepared bendable part is bent once, and the prepared display screen body with the plurality of bendable parts can be bent at a plurality of positions. Each bendable region comprises a first elastic layer and a second elastic layer, and when each bendable part is bent once, one part of the first elastic layer is compressed, and the other part of the first elastic layer can be stretched; similarly, the second elastic layer of the bendable portion corresponding to the compressed first elastic layer is correspondingly stretched, and the second elastic layer of the bendable portion corresponding to the stretched first elastic layer is correspondingly compressed. Therefore, in the case of manufacturing a display panel including a plurality of bendable portions, it is preferable that the stretch resistance of the first elastic layer is set to be the same as the stretch resistance of the second elastic layer, and the compression resistance of the first elastic layer is set to be the same as the compression resistance of the second elastic layer. Therefore, the bending times of the display screen body can be greatly improved. The first elastic layer and the second elastic layer can be prepared by adopting the same material, so that the compression resistance of the first elastic layer is the same as that of the second elastic layer, and the stretch resistance of the first elastic layer is the same as that of the second elastic layer. For example, the first elastic layer and the second elastic layer are both made of rubber.
