Technical Field

[0001] This application belongs to the field of display, and in particular relates to a display module and display device. Background Technology

[0002] With the continuous development of technology, the application scenarios of display devices are becoming more and more widespread, and display devices with good bending ability have also emerged. Display devices can switch between a bent state and a flat state through their own bending deformation. Display devices in a bent state are easy to carry and store, while display devices in a flat state have a better display effect. Summary of the Invention

[0003] This application provides a display module and display device, which aim to reduce creases in the display module.

[0004] In a first aspect, embodiments of this application provide a display module, the display module including: a display panel having a light-emitting surface and a non-light-emitting surface facing away from each other in a first direction; and a support member including a support plate disposed on the side of the non-light-emitting surface facing away from the light-emitting surface, the material of the support plate including glass.

[0005] Secondly, embodiments of this application provide a display device, which includes the display module as described in the first aspect embodiment above.

[0006] This application provides a display module including a display panel and a support member. The display panel has a light-emitting surface and a non-light-emitting surface facing away from each other in a first direction. The light-emitting surface of the display panel can be used to emit light outward to realize the display function of the display panel. The support member includes a support plate disposed on the side of the non-light-emitting surface facing away from the light-emitting surface. The support plate can provide good support for the display panel, and the support plate is unlikely to block or affect the light emission of the display panel. By using glass as the material of the support plate, the support plate, made of glass, is not prone to plastic deformation and creep when it undergoes corresponding bending deformation along with the display panel. This allows the support plate to maintain good support for the display panel as a whole, thereby effectively reducing creases in the display module. Attached Figure Description

It should be understood that the specific embodiments described herein are intended only to explain this application and not to limit it.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0013] With the continuous development of technology, the application scenarios of display devices are becoming more and more widespread, and display devices with good bending ability have also emerged. Display devices can switch between a bent state and a flat state through their own bending deformation. Display devices in a bent state are easy to carry and store, while display devices in a flat state have a better display effect.

[0014] In related technologies, display modules often include a display panel and a support component. The display panel has good bending ability, and the support component is used to support the display panel. The support component needs to bend and deform along with the display panel.

[0015] However, the support components in the display module are often made of metal. After repeated bending and deformation, the support components made of metal are prone to plastic deformation and creep, which can easily cause the adhesive material in the display module to deform, making the display module prone to creases.

[0016] To address the aforementioned technical problems, this application is provided. To better understand this application, the display module and display device according to embodiments of this application will be described in detail below with reference to the accompanying drawings.

Figure 4 This is a schematic diagram of the structure of a display module 10 in a bent state according to an embodiment of this application. Figure 5 This is a schematic diagram of the structure of a display module 10 in a bent state provided in another embodiment of this application.

[0018] In the accompanying drawings of this application, the X direction can represent a first direction, the Y direction can represent a second direction, and the Z direction can represent a third direction. The first direction X, the second direction Y, and the third direction Z can intersect each other; for example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other.

[0019] like Figures 1 to 5 As shown, this application embodiment provides a display module 10, which includes: a display panel 200, the display panel 200 having a light-emitting surface 200a and a non-light-emitting surface 200b facing away from each other in a first direction X; and a support member 100, including a support plate 110 disposed on the side of the non-light-emitting surface 200b facing away from the light-emitting surface 200a, the material of the support plate 110 including glass.

[0020] An embodiment of this application provides a display module 10 including a display panel 200 and a support member 100.

[0021] Optionally, the display panel 200 provided in this application embodiment can be configured in various ways. For example, the display panel 200 provided in this application embodiment can be a display panel 200 that works based on the organic light-emitting diode (OLED) display principle or a display panel 200 that works based on the light-emitting diode (LED) display principle.

[0022] For ease of description, the following embodiments will be described using the display panel 200 provided in the embodiments of this application as an example of its operation based on the organic light-emitting diode display principle.

[0023] The display panel 200 has a light-emitting surface 200a and a non-light-emitting surface 200b facing away from each other in the first direction X. The light-emitting surface 200a of the display panel 200 can be used to emit light outward to realize the display operation of the display panel 200.

[0024] For example, during the light emission display process of the display panel 200, light can be emitted outward from the light-emitting surface 200a. The light-emitting surface 200a of the display panel 200 can be used for light emission display, while the backlight surface of the display panel 200 may not participate in the light emission display operation of the display panel 200.

[0025] Optionally, the display panel 200 may include an array substrate 210 and a light-emitting device 230 disposed on the side of the array substrate 210 facing away from the support member 100. The light-emitting device 230 can be used for light-emitting display. The backlight surface of the display panel 200 may be the surface of the array substrate 210 facing away from the light-emitting device 230.

[0026] Optionally, in the direction away from the array substrate 210, the light-emitting device 230 may include a first electrode 231, a light-emitting functional layer 232 and a second electrode 233 stacked in sequence.

[0027] Optionally, the light-emitting functional layer 232 may include a first common layer 232a, a second common layer 232c disposed on the side of the first common layer 232a facing away from the substrate, and a light-emitting structure 232b disposed between the first common layer 232a and the second common layer 232c. For example, the first common layer 232a may include a hole injection layer (HIL) and a hole transport layer (HTL), and the second common layer 232c may include an electron injection layer (EIL) and an electron transport layer (ETL).

[0028] Optionally, the first electrode 231 and the second electrode 233 can serve as pixel electrodes of the display panel 200. One of the first electrode 231 and the second electrode 233 can serve as an anode, and the other can serve as a cathode to drive the light-emitting functional layer 232 to emit light. In this embodiment, the first electrode 231 is used as the anode of the display panel 200, and the second electrode 233 is used as the cathode of the display panel 200 for illustrative purposes.

[0029] Optionally, the second electrodes 233 of each light-emitting device 230 can be electrically connected to each other, thereby facilitating the control of the display panel 200. For example, the second electrodes 233 of each light-emitting device 230 can be integrally formed. Optionally, the first common layer 232a of each light-emitting device 230 can be integrally formed, and the second common layer 232c of each light-emitting device 230 can be integrally formed, to facilitate the fabrication of the display panel 200.

[0030] Optionally, the display panel 200 further includes a pixel definition layer 220 disposed on the side of the first electrode 231 facing away from the array substrate 210. The pixel definition layer 220 may have a pixel opening 220a, and the light-emitting functional layer 232 may be partially located within the pixel opening 220a. At least a portion of the surface of the first electrode 231 facing away from the array substrate 210 may be exposed through the pixel opening 220a and contacted with the light-emitting functional layer 232. The pixel definition layer 220 can be used to participate in dividing the sub-pixels of the display panel 200.

[0031] Optionally, the display module 10 may have a non-bending area A1 and a bending area A2. The display module 10 located in the bending area A2 (e.g., the display panel 200 and the support member 100 located in the bending area A2) may have better bending ability to enable the bending of the display module 10.

[0032] Optionally, the display panel 200 may be located within the non-bending area A1 and the bending area A2.

[0033] Optionally, the number of bending areas A2 can be set in various ways, and the display module 10 may include two or more non-bending areas A1. For example, the display module 10 may include two non-bending areas A1, which may be located on different sides of the bending area A2. When the display module 10 in the bending area A2 undergoes bending deformation, the display modules 10 in the two non-bending areas A1 may move closer to or further away from each other.

[0034] For ease of description, the following embodiments will be illustrated by showing that the display module 10 has two non-bending regions A1.

[0035] Optionally, the display module 10 may have a bent state and a flattened state. When the display module 10 is in the flattened state, the non-bent area A1 is located on at least one side of the bent area A2 in the second direction Y. For example, when the display module 10 is in the flattened state, the two non-bent areas A1 may be located on opposite sides of the bent area A2 in the second direction Y. The display module 10 in the flattened state can be relatively flat, allowing the display module 10 to have a better display effect.

[0036] Optionally, when the display module 10 is in a flattened state, the size of the display module 10 in a single non-bending region A1 in the second direction Y can be larger than the size of the display module 10 in a single bending region A2 in the second direction Y (in the accompanying drawings of this application, in order to facilitate the illustration of the structural features of the display module 10 in the bending region A2, the display module 10 in the non-bending region A1 has been reduced in size, that is, the size of the display module 10 in the non-bending region A1 shown in the accompanying drawings does not represent the size of the display module 10 in the non-bending region A1 in the actual product), so that the non-bending region A1 with higher structural stability can have a larger size, which is beneficial to improving the display effect of the display module 10.

[0037] Optionally, the display module 10 can be bent about a rotation axis extending in the third direction Z.

[0038] Optionally, when the display module 10 is in a bent state, there are multiple ways to bend the display module 10. The display module 10 can be bent outward or inward.

[0039] For example, such as Figure 4 As shown, the display panel 200 may include a first panel portion 201 and a second panel portion 202 located in two non-bending regions A1, respectively. When the display module 10 is in a bent state, the display module 10 can be bent along the direction in which the backlight surfaces of the first panel portion 201 and the second panel portion 202 face each other, thereby realizing the outward folding of the display module 10; as Figure 5As shown, when the display module 10 is in a bent state, the display module 10 can be bent along the direction in which the light-emitting surfaces 200a of the first panel portion 201 and the second panel portion 202 face each other, so as to realize the inward folding of the display module 10.

[0040] Optionally, when the display module 10 is bent in an outward fold, in the bent state, the light-emitting surface 200a of the first panel portion 201 may be located on the side of the backlight surface of the first panel portion 201 that is away from the second panel portion 202, and the light-emitting surface 200a of the second panel portion 202 may be located on the side of the backlight surface of the second panel portion 202 that is away from the first panel portion 201. When the display module 10 is bent in an inward fold, in the bent state, the backlight surface of the first panel portion 201 may be located on the side of the light-emitting surface 200a of the first panel portion 201 that is away from the second panel portion 202, and the backlight surface of the second panel portion 202 may be located on the side of the light-emitting surface 200a of the second panel portion 202 that is away from the first panel portion 201.

[0041] The support member 100 includes a support plate 110 disposed on the side of the non-light-emitting surface 200b away from the light-emitting surface 200a. The support plate 110 can provide good support for the display panel 200, and the support plate 110 is not likely to block or affect the light emission display of the display panel 200.

[0042] Optionally, the support plate 110 can be located in the bending area A2 and the non-bending area A1, so that the support plate 110 can provide good support for the display panel 200 in both the bending area A2 and the non-bending area A1.

[0043] By setting the material of the support plate 110 to include glass, the support plate 110, which is made of glass, is not prone to plastic deformation and creep when it undergoes corresponding bending deformation along with the display panel 200. This allows the support plate 110 to maintain a good support effect on the display panel 200 as a whole, thereby effectively reducing the creases of the display module 10.

[0044] Furthermore, by using glass as the material for the support plate 110, it can also have better light transmittance, meaning light can pass through the support plate 110 more effectively. For example, the support plate 110 made of glass material has high transmittance in the infrared (IR) to visible light (Vis) bands. This allows the display module 10 to be used in a display device, where the display device can also include a light-sensing device for sensing light. The light-sensing device can be disposed on the side of the support member 100 facing away from the display panel 200, and can sense light effectively through the support plate 110. For example, the light-sensing device may include a color temperature sensor, an under-display camera, a fingerprint reader, or other devices that can be used to sense light.

[0045] In some embodiments of this application, the elastic modulus of the support plate 110 can be set in various ways, and the elastic modulus of the support plate 110 can be set according to the bending performance requirements and support performance requirements of the support plate 110.

[0046] Optionally, the elastic modulus of the support plate 110 is not less than 60 GPa and not more than 120 GPa. By setting the elastic modulus of the support plate 110 to not less than 60 GPa, the elastic modulus of the support plate 110 is not likely to be too small, so that the support plate 110 can have good support performance and structural stability. This makes it less likely for the support plate 110 to undergo large plastic deformation and creep after repeated bending deformation along with the display panel 200, which helps to reduce creases in the display module 10. By setting the elastic modulus of the support plate 110 to not more than 120 GPa, the elastic modulus of the support plate 110 is not likely to be too large, so that the support plate 110 can be bent and deformed more easily along with the display panel 200, which helps to reduce the overall bending difficulty of the display module 10.

[0047] For example, the elastic modulus of the support plate 110 may be 60 GPa, 65 GPa, 70 GPa, 75 GPa, 80 GPa, 85 GPa, 90 GPa, 95 GPa, 100 GPa, 105 GPa, 110 GPa, 115 GPa or 120 GPa.

[0048] In some embodiments of this application, the material of the support plate 110 can be configured in various ways. For example, the material of the support plate 110 in each region can be the same; or, the material of the support plate 110 in different regions can be different. For another example, the support plate 110 can be formed solely of glass, meaning the material of the support plate 110 can consist only of glass; or, the support plate 110 can be formed by mixing glass with other materials, meaning the material of the support plate 110 can include glass and other materials.

[0049] In some embodiments, the material of the support plate 110 in the bending region A2 includes glass, so that when the support plate 110 in the bending region A2 undergoes bending deformation along with the display panel 200, the support plate 110 in the bending region A2 is not prone to plastic deformation and creep, so that the support plate 110 in the bending region A2 can maintain a good support effect on the display panel 200 as a whole, thereby effectively reducing the creases of the display module 10.

[0050] Optionally, when the display module 10 is in a bent state, there are multiple ways to set the bending shape of the display module 10 in the bending area A2.

[0051] As an example, such as Figure 4 and Figure 5As shown, when the display module 10 is in a bent state, the degree of bending of the display module 10 at various points within the bending region A2 can be the same or approximately the same, that is, the bending radius of the display module 10 at various points within the bending region A2 can be the same or approximately the same. In this example, the material of the support plate 110 within the bending region A2 can be glass, so that the support plate 110 within the entire bending region A2 is not prone to plastic deformation and creep.

[0052] Figure 6 This is a schematic diagram of the structure of a display module 10 in a bent state according to another embodiment of this application.

[0053] As another example, such as Figure 6 As shown, the bending region A2 may include a transition region A21 connected to the non-bending region A1 and a main bending region A22 located on the side of the transition region A21 away from the non-bending region A1. When the display module 10 is in a bent state, the degree of bending of the display module 10 in the transition region A21 may be less than the degree of bending of the display module 10 in the main bending region A22, that is, the bending radius of the display module 10 in the transition region A21 may be greater than the bending radius of the display module 10 in the main bending region A22. In this example, the material of the support plate 110 in the transition region A21 and / or the main bending region A22 is glass. By setting the material of the support plate 110 in the main bending region A22 to include glass, the support plate 110 in the main bending region A22, which has a large degree of bending in the bending state, is less prone to plastic deformation and creep. By setting the material of the support plate 110 in the transition region A21 to include glass, the support plate 110 in the transition region A21, which has a large degree of bending in the bending state, is less prone to plastic deformation and creep. At the same time, it is also beneficial to increase the overall light transmission area of ​​the support plate 110 in the bending region A2, so that the support plate 110 in the bending region A2 is less likely to cause a large obstruction of light.

[0054] In some embodiments, the material of the support plate 110 in the non-bending region A1 may be the same as or different from the material of the support plate 110 in the bending region A2.

[0055] As an example, the material of the support plate 110 in the non-bending area A1 may not include glass. For example, the material of the support plate 110 in the non-bending area A1 may include metal or carbon fiber materials, so that the support plate 110 in the non-bending area A1 can have good material strength, which is beneficial for the support plate 110 in the non-bending area A1 to provide better support for the display panel 200 in the non-bending area A1.

[0056] As another example, the material of the support plate 110 in the non-bending region A1 can be glass, so that the material of the support plate 110 in the non-bending region A1 can be the same as the material of the support plate 110 in the bending region A2. This allows the support plate 110 in the non-bending region A1 and the support plate 110 in the bending region A2 to be integrally formed, which is beneficial for the fabrication of the support plate 110. Furthermore, by setting the material of the support plate 110 in the non-bending region A1 to glass, the support plate 110 in the non-bending region A1 can also have good light transmittance, which is beneficial for placing a larger photosensitive device below the display module 10.

[0057] Figure 7 This is a schematic diagram of the structure of a display module 10 provided in an embodiment of this application. Figure 8 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application. Figure 9 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application. To facilitate the illustration of the structure of the support plate 110, some of the figures (e.g., Figures 7 to 9 and the embodiments described below. Figures 10 to 17 The support plate 110 in (etc.) can be a schematic diagram of the structure after sectioning.

[0058] like Figures 7 to 9 As shown, in some embodiments, the support plate 110 within the bending region A2 has a first functional opening 110a. The first functional opening 110a is provided to improve the bending performance of the support plate 110 within the bending region A2.

[0059] Optionally, the first functional opening 110a may penetrate the support plate 110 (not shown in the figure), so that the support plate 110 in the bending area A2 can have better bending performance; or, the first functional opening 110a may not penetrate the support plate 110, so that the support plate 110 in the bending area A2 can have better structural strength.

[0060] For ease of description, the following embodiments will be described using the example of the first functional opening 110a not penetrating the support plate 110.

[0061] In some embodiments of this application, the position of the first functional opening 110a can be set in various ways.

[0062] In some examples, such as Figure 7 As shown, at least a portion of the first functional opening 110a is formed on the side of the support plate 110 facing the display panel 200, and / or, as Figure 8 and Figure 9 As shown, at least a portion of the first functional opening 110a is formed on the side of the support plate 110 away from the display panel 200.

[0063] In these examples, when the first functional opening 110a is only opened on the side of the support plate 110 facing the display panel 200, it is beneficial to have better flatness on the surface of the support plate 110 facing away from the display panel 200, and it is also beneficial for the display module 10 to be bent in an inward folding manner. When the first functional opening 110a is only opened on the side of the support plate 110 facing away from the display panel 200, it is beneficial to have better flatness on the surface of the support plate 110 facing away from the display panel 200, and it is also beneficial for the display module 10 to be bent in an outward folding manner. When a portion of the first functional opening 110a is opened on the side of the support plate 110 facing the display panel 200, and another portion of the first functional opening 110a is opened on the side of the support plate 110 facing away from the display panel 200, the support plate 110 can have better bending performance, and it is also beneficial for the display module 10 to be bent in both outward and inward folding manner.

[0064] Figure 10 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0065] like Figure 10 As shown, in some embodiments, the display module 10 further includes a first adhesive layer 300 disposed between the support plate 110 and the display panel 200. The support plate 110 can be connected to the upper device structure through the first adhesive layer 300 (for example, the support plate 110 can be connected to the display panel 200 through the first adhesive layer 300).

[0066] Optionally, the material of the first adhesive layer 300 may include a transparent adhesive, so that the first adhesive layer 300 can have good light transmittance. For example, the first adhesive layer 300 may be a pressure-sensitive adhesive (PSA).

[0067] Optionally, the first adhesive layer 300 within the bending region A2 has a second functional opening 300a, the projection of the second functional opening 300a in the first direction X at least partially overlapping the projection of the first functional opening 110a in the first direction X. The second functional opening 300a improves the bending performance of the first adhesive layer 300 and makes it less prone to large deformation within the bending region A2, thereby effectively reducing the compression and accumulation phenomenon caused by the first adhesive layer 300 bending along with the display panel 200.

[0068] Optionally, when at least a portion of the first functional opening 110a is opened on the side of the support plate 110 facing the display panel 200, a portion of the first adhesive layer 300 may be located within the first functional opening 110a, which is beneficial to increasing the contact area between the first adhesive layer 300 and the support plate 110, and allows the first adhesive layer 300 to play a certain flattening role on the step difference at the first functional opening 110a.

[0069] In some embodiments of this application, the size of the first functional opening 110a can be set in various ways, and the size of the first functional opening 110a can be set according to the bending requirements of the display module 10.

[0070] Figure 11 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application. Figure 12 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0071] like Figure 11 and Figure 12 As shown, in some embodiments, when a portion of the first functional openings 110a are opened on the side of the support plate 110 facing the display panel 200, and another portion of the first functional openings 110a are opened on the side of the support plate 110 away from the display panel 200, the single first functional opening 110a opened on the side of the support plate 110 facing the display panel 200 has a first size in the first direction X (H1 in the figure can indicate the first size), and the single first functional opening 110a opened on the side of the support plate 110 away from the display panel 200 has a second size in the first direction X (H2 in the figure can indicate the second size), and the first size and the second size are not equal.

[0072] Optionally, a single first functional opening 110a on the side of the support plate 110 facing the display panel 200 has a first dimension in the first direction X. This can mean that when the display module 10 is in a flattened state, the single first functional opening 110a on the side of the support plate 110 facing the display panel 200 has a first dimension in the first direction X. A single first functional opening 110a on the side of the support plate 110 away from the display panel 200 has a second dimension in the first direction X. This can mean that when the display module 10 is in a flattened state, the single first functional opening 110a on the side of the support plate 110 away from the display panel 200 has a second dimension in the first direction X.

[0073] In this embodiment, since the larger the size of the first functional opening 110a in the first direction X when it is flattened, the better the bending performance at the location of the first functional opening 110a. Therefore, by setting the first size and the second size to be unequal, the bending ability of the support plate 110 when bending in different directions can be different, so that the support plate 110 can have different bending capabilities according to the bending requirements of the display module 10.

[0074] For example, when the first size is larger than the second size, the support plate 110 can be bent toward the side away from the display panel 200 more than the support plate 110 can be bent toward the side of the display panel 200, which is beneficial for the display module 10 to be bent in a better outward folding manner; while when the first size is smaller than the second size, the support plate 110 can be bent toward the side of the display panel 200 more than the support plate 110 can be bent toward the side away from the display panel 200, which is beneficial for the display module 10 to be bent in a better inward folding manner.

[0075] Figure 13 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application. Figure 14 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0076] like Figure 13 and Figure 14 As shown, in some embodiments, when a portion of the first functional openings 110a are opened on the side of the support plate 110 facing the display panel 200, and another portion of the first functional openings 110a are opened on the side of the support plate 110 away from the display panel 200, the single first functional opening 110a opened on the side of the support plate 110 facing the display panel 200 has a third dimension in the second direction Y (W1 in the figure can be used to indicate the third dimension), and the single first functional opening 110a opened on the side of the support plate 110 away from the display panel 200 has a fourth dimension in the second direction Y (W2 in the figure can be used to indicate the fourth dimension), and the third dimension and the fourth dimension are not equal.

[0077] Optionally, a single first functional opening 110a on the side of the support plate 110 facing the display panel 200 has a third dimension in the second direction Y. This can refer to the single first functional opening 110a on the side of the support plate 110 facing the display panel 200 having a third dimension in the second direction Y when the display module 10 is in a flattened state. A single first functional opening 110a on the side of the support plate 110 away from the display panel 200 has a fourth dimension in the second direction Y. This can refer to the single first functional opening 110a on the side of the support plate 110 away from the display panel 200 having a fourth dimension in the second direction Y when the display module 10 is in a flattened state.

[0078] In this embodiment, since the larger the size of the first functional opening 110a in the second direction Y when it is flattened, the better the bending performance at the location of the first functional opening 110a. Therefore, by setting the third and fourth dimensions to be different, the bending ability of the support plate 110 when bending in different directions can be different, so that the support plate 110 can have different bending capabilities according to the bending requirements of the display module 10.

[0079] For example, when the third dimension is larger than the fourth dimension, the support plate 110 can be bent toward the side away from the display panel 200 more than the support plate 110 can be bent toward the side of the display panel 200, which is beneficial for the display module 10 to be bent in a better outward folding manner; while when the third dimension is smaller than the fourth dimension, the support plate 110 can be bent toward the side of the display panel 200 more than the support plate 110 can be bent toward the side away from the display panel 200, which is beneficial for the display module 10 to be bent in a better inward folding manner.

[0080] Based on the aforementioned analysis of the first, second, third, and fourth dimensions, different settings can be made for the first, second, third, and fourth dimensions depending on the bending form of the display module 10.

[0081] As an example, when the display module 10 needs to be bent outwards, the first dimension can be set to be greater than the second dimension and the third dimension equal to the fourth dimension; or, the first dimension can be set to be equal to the second dimension and the third dimension greater than the fourth dimension; or, the first dimension can be set to be greater than the second dimension and the third dimension greater than the fourth dimension.

[0082] As another example, when the display module 10 needs to be bent in an inward fold, the first size can be set to be smaller than the second size and the third size to be equal to the fourth size; or, the first size can be set to be equal to the second size and the third size to be smaller than the fourth size; or, the first size can be set to be smaller than the second size and the third size to be smaller than the fourth size.

[0083] In some embodiments of this application, the shape of the first functional opening 110a can be configured in various ways.

[0084] Figure 15 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application. Figure 16 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0085] like Figures 11 to 16 As shown, in some embodiments, the first functional opening 110a includes a first opening 110aa, the size of which gradually decreases in the first direction X along the direction from the bent region A2 to the non-bent region A1.

[0086] For example, the size of the first opening 110aa gradually decreases in the direction from the bent region A2 to the non-bent region A1 in the first direction X. This can refer to the first opening 110aa gradually decreasing in the direction from the bent region A2 to the non-bent region A1 in the first direction X when the display module 10 is in a flattened state.

[0087] Optionally, there are several ways to achieve a gradual decrease in the size of the first opening 110aa in the first direction X, along the direction from the bent region A2 to the non-bent region A1. As an example, such as Figure 15 As shown, the surface of the support plate 110 facing the first opening 110aa may include two planes whose extending directions intersect, and the extending directions of both planes intersect the first direction X. As another example, such as... Figure 16 As shown, the surface of the support plate 110 facing the first opening 110aa can be an arc surface.

[0088] In these embodiments, during the bending process of the support plate 110, the degree of bending of the support plate 110 is smaller when it is closer to the non-bending region A1 within the bending region A2 (for example, the bending radius of the support plate 110 is larger when it is closer to the non-bending region A1 within the bending region A2), that is, the degree of bending of the support plate 110 located at the center of the bending region A2 is greater than the degree of bending of the support plate 110 located at the edge of the bending region A2.

[0089] Therefore, by setting the size of the first opening 110aa to gradually decrease in the first direction X along the direction from the bending region A2 to the non-bending region A1, the thickness of the support plate 110 with a greater degree of bending in the bending region A2 can be less than the thickness of the support plate 110 with a lesser degree of bending in the bending region A2 during the bending process of the support plate 110. This is beneficial to improving the bending performance of the support plate 110 in the bending region A2, while the position with a greater thickness in the support plate 110 in the bending region A2 can have better structural strength, and it is also beneficial to improve the support effect of the support plate 110 on the display panel 200.

[0090] In some embodiments, the dimension of at least one first opening 110aa in the second direction Y is equal to the dimension of the bent region A2 in the second direction Y.

[0091] For example, the fact that at least one first opening 110aa has the same size in the second direction Y as the bending region A2 in the second direction Y can mean that when the display module 10 is in a flattened state, at least one first opening 110aa has the same size in the second direction Y as the bending region A2 in the second direction Y.

[0092] In this embodiment, by setting at least one first opening 110aa with a size equal to that of the bending region A2 in the second direction Y, the first opening 110aa can be provided on each of the support plates 110 in the bending region A2, thereby enabling the support plates 110 in the bending region A2 to have good bending performance as a whole.

[0093] Optionally, at least one first opening 110aa may have a dimension in the third direction Z that is equal to that of the support plate 110 in the third direction Z, so that the first opening 110aa may have a larger dimension in the third direction Z, thereby facilitating the bending of the support plate 110 along the pivot extending in the third direction Z.

[0094] Figure 17 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0095] like Figure 17 As shown, in some embodiments, the first functional opening 110a includes a second opening 110ab, the support plate 110 includes a first main body portion 111 and a first protrusion portion 112 protruding relative to the first main body portion 111 along a first direction X, at least one second opening 110ab is disposed around the first protrusion portion 112, and / or, the first protrusion portion 112 is located between adjacent second openings 110ab.

[0096] Optionally, when the display module 10 is in a flattened state, the width of the second opening 110ab in the second direction Y may be smaller than the width of the first opening 110aa in the second direction Y.

[0097] In this embodiment, by setting a smaller second opening 110ab, it is beneficial to improve the bending performance of the support plate 110 in the bending region A2, while also ensuring that the structural strength of the support plate 110 in the bending region A2 is not too low, which is beneficial to improve the support performance of the support plate 110 in the bending region A2.

[0098] Figure 18 This is a partial structural schematic diagram of a support plate 110 provided in an embodiment of this application. Figure 19 This is a partial structural schematic diagram of a support plate 110 provided in another embodiment of this application. Figure 20 This is a partial structural schematic diagram of a support plate 110 provided in another embodiment of this application.

[0099] Optionally, the shape of the second opening 110ab can be configured in various ways. For example, the projection shape of the second opening 110ab in the first direction X is annular (e.g., Figure 18 As shown), serrated (as shown) Figure 19 (as shown) or broken line (as shown) Figure 20(As shown).

[0100] Optionally, the projection shape of the second opening 110ab in the first direction X is annular, sawtooth, or zigzag. This can refer to the second opening 110ab being annular, sawtooth, or zigzag when the display module 10 is in a flattened state.

[0101] Optionally, when the display module 10 is in a flattened state, the multiple second openings 110ab, which are annular in shape in the first direction X, can be connected to each other to form a grid.

[0102] In some embodiments of this application, the size of the second opening 110ab can be set in various ways, and the size of the second opening 110ab can be set according to the bending requirements of the display module 10.

[0103] Figure 21 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0104] like Figure 21 As shown, in some embodiments, there are multiple second openings 110ab, which are spaced apart in the second direction Y. Among two adjacent second openings 110ab in the second direction Y, the size of the second opening 110ab closer to the non-bending region A1 in the second direction Y is smaller than the size of the second opening 110ab farther from the non-bending region A1 in the second direction Y.

[0105] Optionally, the arrangement of multiple second openings 110ab at intervals in the second direction Y can refer to the arrangement of multiple second openings 110ab at intervals in the second direction Y when the display module 10 is in a flattened state. Optionally, the size of the second opening 110ab in the second direction Y can refer to the size of the second opening 110ab in the second direction Y when the display module 10 is in a flattened state.

[0106] In this embodiment, during the bending process of the support plate 110, the degree of bending of the support plate 110 closer to the non-bending region A1 within the bending region A2 is smaller; that is, the degree of bending of the support plate 110 located at the center of the bending region A2 is greater than that of the support plate 110 located at the edge of the bending region A2. Therefore, by setting the size of the second opening 110ab closer to the non-bending region A1 in the second direction Y to be smaller than that of the second opening 110ab farther from the non-bending region A1 in the second direction Y, during the bending process of the support plate 110, the width of the second opening 110ab at the support plate 110 with a larger degree of bending in the bending region A2 is larger, while the width of the second opening 110ab at the support plate 110 with a smaller degree of bending in the bending region A2 is smaller. This is beneficial to improving the bending performance of the support plate 110 within the bending region A2, and also beneficial to improving the support effect of the support plate 110 on the display panel 200.

[0107] Please continue to refer to Figure 21 In some embodiments, there are multiple first protrusions 112, which are spaced apart in the second direction Y. Among two adjacent first protrusions 112 in the second direction Y, the size of the first protrusion 112 closer to the non-bending region A1 in the second direction Y is larger than the size of the first protrusion 112 farther from the non-bending region A1 in the second direction Y.

[0108] Optionally, the plurality of first protrusions 112 are spaced apart in the second direction Y, which may refer to the plurality of first protrusions 112 being spaced apart in the second direction Y when the display module 10 is in a flattened state. Optionally, the dimension of the first protrusion 112 in the second direction Y may refer to the dimension of the first protrusion 112 in the second direction Y when the display module 10 is in a flattened state.

[0109] In this embodiment, similar to the analysis in the previous embodiment, by setting two adjacent first protrusions 112 in the second direction Y, the size of the first protrusion 112 closer to the non-bending region A1 in the second direction Y is larger than the size of the first protrusion 112 farther from the non-bending region A1 in the second direction Y. This makes it so that during the bending process of the support plate 110, the width of the first protrusion 112 at the support plate 110 with a larger degree of bending in the bending region A2 is smaller, while the width of the first protrusion 112 at the support plate 110 with a smaller degree of bending in the bending region A2 is larger. This is beneficial to improving the bending performance of the support plate 110 in the bending region A2, and also beneficial to improving the support effect of the support plate 110 on the display panel 200.

[0110] Figure 22This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0111] like Figure 22 As shown, in some embodiments, there are multiple second openings 110ab, which are spaced apart in the second direction Y. Among two adjacent second openings 110ab in the second direction Y, the size of the second opening 110ab closer to the non-bending region A1 in the first direction X is smaller than the size of the second opening 110ab farther from the non-bending region A1 in the first direction X.

[0112] Optionally, the size of the second opening 110ab in the first direction X may refer to the size of the second opening 110ab in the first direction X when the display module 10 is in a flattened state.

[0113] In this embodiment, similar to the analysis in the previous embodiment, by setting the second opening 110ab closer to the non-bending region A1 in the second direction Y to have a smaller size in the first direction X than the second opening 110ab farther from the non-bending region A1 in the first direction X, during the bending process of the support plate 110, the second opening 110ab at the support plate 110 with a larger degree of bending in the bending region A2 has a larger depth, while the second opening 110ab at the support plate 110 with a smaller degree of bending in the bending region A2 has a smaller depth. This is beneficial to improving the bending performance of the support plate 110 in the bending region A2, and also beneficial to improving the support effect of the support plate 110 on the display panel 200.

[0114] In some embodiments of this application, the first functional opening 110a may include only the first opening 110aa; or, the first functional opening 110a may include only the second opening 110ab; or, the first functional opening 110a may include both the first opening 110aa and the second opening 110ab.

[0115] Optionally, when the first functional opening 110a includes a first opening 110aa and a second opening 110ab, the first opening 110aa and the second opening 110ab can be respectively disposed on both sides of the support plate 110 in the first direction X, so that the bending ability of the support plate 110 when bending in different directions can be different.

[0116] Figure 23 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0117] For example, such as Figure 21 and Figure 22As shown, the first opening 110aa can be formed on the side of the support plate 110 facing the display panel 200, and the second opening 110ab can be formed on the side of the support plate 110 away from the display panel 200. Or, for example, as Figure 23 As shown, the first opening 110aa can be opened on the side of the support plate 110 away from the display panel 200, and the second opening 110ab can be opened on the side of the support plate 110 facing the display panel 200.

[0118] In some embodiments, such as Figure 23 As shown, when at least a portion of the second opening 110ab is formed on the side of the support plate 110 facing the display panel 200, the first adhesive layer 300 may be at least partially located within the second opening 110ab.

[0119] By setting the first adhesive layer 300 within the second opening 110ab, and by reasonably setting the shape of the second opening 110ab (for example, setting the projection shape of the second opening 110ab in the first direction X to be annular, serrated, or zigzag), it is beneficial to increase the contact area between the first adhesive layer 300 and the support plate 110, thereby improving the adhesion between the first adhesive layer 300 and the support plate 110, making the connection between the support plate 110 and the first adhesive layer 300 more stable, and thus enabling the display module 10 to achieve a smaller bending radius.

[0120] In some embodiments, the first adhesive layer 300 can be directly bonded to the display panel 200, and the support plate 110 can be directly connected to the display panel 200 through the first adhesive layer 300. That is, no other film layer structure is required between the first adhesive layer 300 and the display panel 200, which makes the overall thickness of the display module 10 smaller, which is beneficial for the display module 10 to achieve a smaller bending radius.

[0121] Optionally, the thickness of the support plate 110 at the location where the first functional opening 110a is not provided (e.g., the thickness of the support plate 110 in the non-bending region A1) may be no less than 30 μm and no more than 180 μm. The thickness of the support plate 110 at the location corresponding to the first functional opening 110a may be no less than 25 μm and no more than 180 μm (e.g., at the location corresponding to the first opening 110aa, the thickness of the first cover plate 700 in the bending region A2 may be no less than 25 μm and no more than 180 μm; or, for example, at the location corresponding to the fourth opening 700ab, the thickness of the second main body portion 710 in the bending region A2 may be no less than 25 μm and no more than 50 μm).

[0122] Figure 24 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0123] In other embodiments, such as Figure 24As shown, the display module 10 also includes a support film 400 disposed between the display panel 200 and the first adhesive layer 300. The support film 400 can be used to assist in supporting the display panel 200, which is beneficial to improving the overall flatness of the display panel 200.

[0124] Optionally, the material of the support membrane 400 may include a polymer.

[0125] Optionally, the support film 400 and the display panel 200 can be connected by a first adhesive material G1. For example, the first adhesive material G1 may include pressure-sensitive adhesive, and the support film 400 and the display panel 200 can be connected by a pressure-sensitive adhesive covering the entire surface.

[0126] In some embodiments, the projection of the support plate 110 in the first direction X is located within the projection of the display panel 200 in the first direction X.

[0127] Optionally, the projected area of ​​the support plate 110 in the first direction X may be smaller than the projected area of ​​the display panel 200 in the first direction X, and the projected edge of the support plate 110 in the first direction X may be spaced apart from the projected edge of the display panel 200 in the first direction X.

[0128] In this optional embodiment, by setting the projection of the support plate 110 in the first direction X to be within the projection of the display panel 200 in the first direction X, the support plate 110 can have a smaller size than the display panel 200. This makes it less likely that the support plate 110 located below the display panel 200 will collide with other device structures and be damaged when the display module 10 is installed into other device structures (e.g., when the display module 10 is installed into the middle frame), thereby facilitating the installation of the display module 10.

[0129] Furthermore, by setting the projection of the support plate 110 in the first direction X to be within the projection of the display panel 200 in the first direction X, it is also beneficial to improve the manufacturing efficiency of the display module 10.

[0130] Figure 25 This is a schematic diagram of the structure of a display panel motherboard 20 provided in an embodiment of this application.

[0131] For example, such as Figure 25As shown, the display panel motherboard 20 can be cut to prepare multiple display panels 200 and a support film 400 located below the display panels 200. This preparation process is beneficial for reducing the bezel of the display panels 200 (for example, reducing the bezel size by 0.1mm to 0.3mm), thereby improving the screen-to-body ratio of the display module 10. Specifically, the display panel motherboard 20 may include multiple panel areas 20a, and a single panel area 20a can be used to form a single display panel 200. That is, the panel area 20a in the display panel motherboard 20 can be cut off using a cutting process to form the display panel 200. Furthermore, the support film 400 material can be adhered to the bottom of the display panel motherboard 20 with an adhesive. When the panel area 20a in the display panel motherboard 20 is cut using a cutting process (such as laser cutting), the support film 400 can be cut together to obtain a block-shaped display panel 200 and a block-shaped support film 400 located below the display panel 200. Before cutting the display panel motherboard 20 and the support film 400, a block-shaped support plate 110 can be placed below the corresponding panel area 20a to provide support for the panel area 20a. Based on this, by positioning the projection of the support plate 110 in the first direction X within the projection of the display panel 200 in the first direction X, the arrangement of the support plate 110 is less likely to affect the cutting process of the display panel motherboard 20, thereby improving the manufacturing efficiency of the display module 10.

[0132] Optionally, the distance between the projected edge of the support plate 110 in the first direction X and the projected edge of the display panel 200 in the first direction X can be no less than 100 μm and no more than 250 μm. By setting the distance between the projected edge of the support plate 110 in the first direction X and the projected edge of the display panel 200 in the first direction X to be no less than 100 μm, the size of the support plate 110 is not too large, allowing for larger cutting process errors when cutting the display panel mother plate 20, which is beneficial to the fabrication of the display module 10. Furthermore, it also ensures that when the display module 10 is installed into other device structures, the support plate 110 has a suitable distance from other device structures, thus facilitating the installation of the display module 10. By setting the distance between the projected edge of the support plate 110 in the first direction X and the projected edge of the display panel 200 in the first direction X to be no more than 250 μm, the size of the support plate 110 is not too small, allowing the support plate 110 to provide better support for the display panel 200 above it.

[0133] Optionally, the projection of the support film 400 in the first direction X can coincide with the projection of the display panel 200 in the first direction X, so that when the panel area 20a in the display panel mother board 20 is cut using a cutting process, the support film 400 can be cut together to obtain a block-shaped display panel 200 and a block-shaped support film 400 located below the display panel 200.

[0134] Figure 26 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0135] In some embodiments, the display module 10 further includes a first protective structure BS1 disposed on the periphery of the support plate 110 in a direction perpendicular to the first direction X. The first protective structure BS1 can be used to protect the edge of the support plate 110. When the display module 10 is installed into other device structures (e.g., when the display module 10 is installed into the middle frame), the first protective structure BS1 can provide better protection for the edge of the support plate 110, making it less likely for the support plate 110 located below the display panel 200 to collide with other device structures and be damaged, thereby facilitating the installation of the display module 10.

[0136] Optionally, the material of the first protective structure BS1 can be configured in various ways. For example, the material of the first protective structure BS1 may include an adhesive, allowing it to effectively cover the edge of the support plate 110 while also providing some impact resistance. In a further example, a portion of the first adhesive layer 300 extends to the periphery of the support plate 110 in a direction perpendicular to the first direction X and is reused as the first protective structure BS1. This eliminates the need for a separate process to fabricate the first protective structure BS1; it can be fabricated simultaneously with the fabrication of the first adhesive layer 300, thereby improving the fabrication efficiency of the display module 10.

[0137] In some embodiments of this application, the position and size of the first protective structure BS1 can be configured in various ways.

[0138] In some examples, such as Figure 26 As shown, the projection of the edge of the first protective structure BS1 on the side away from the support plate 110 in the first direction X can be set to coincide with the projection of the edge of the display panel 200 in the first direction X, so that the first protective structure BS1 is not easy to bulge outward relative to the edge of the display panel 200, which is beneficial to reducing the bezel size of the display module 10.

[0139] Figure 27 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0140] In other examples, such as Figure 27As shown, the projection of the edge of the first protective structure BS1 away from the support plate 110 in the first direction X and the projection of the edge of the display panel 200 in the first direction X can be spaced apart, so that the first protective structure BS1 can have a larger size and protrude outward relative to the edge of the display panel 200. This allows the first protective structure BS1 to make contact with other device structures before the support plate 110 and the display panel 200 when the display module 10 is installed in other device structures, which is beneficial to improving the edge protection of the support plate 110 and the display panel 200 by the first protective structure BS1, thereby facilitating the installation of the display module 10.

[0141] Optionally, the projection of the edge of the first protective structure BS1 on the side away from the support plate 110 in the first direction X may be located on the side where the projection of the edge of the display panel 200 in the first direction X is away from the projection of the support plate 110 in the first direction X.

[0142] For example, the projection of the edge of the first protective structure BS1 away from the support plate 110 in the first direction X and the projection of the edge of the display panel 200 in the first direction X have a first gap (D1 in the figure can indicate the first gap). The first gap is not less than 30 μm and not more than 250 μm. By setting the first gap to be not less than 30 μm, the size of the first protective structure BS1 is not likely to be too small, which is beneficial to improving the protective effect of the first protective structure BS1. By setting the first gap to be not more than 250 μm, the size of the first protective structure BS1 is not likely to be too large, which is beneficial to reducing the bezel size of the display module 10 and making it easier to install the display module 10 into other device structures.

[0143] Figure 28 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0144] In some embodiments, such as Figure 8 As shown, the display module 10 also includes an optical layer 500 disposed on the side of the display panel 200 opposite to the support member 100. The optical layer 500 can be used to modulate the light emitted by the display panel 200 to improve the overall display effect of the display module 10. For example, the optical layer 500 may include a polarizer or other thin film that can be used to modulate light.

[0145] Optionally, the optical layer 500 and the display panel 200 can be connected by a second adhesive material G2. For example, the second adhesive material G2 may include optically clear adhesive (OCA), and the optical layer 500 and the display panel 200 can be connected by a solid optical adhesive covering the entire surface.

[0146] In some other embodiments, the display module 10 may not include the optical layer 500, that is, the optical layer 500 may not be provided above the display panel 200, which can make the overall thickness of the display module 10 smaller, which is beneficial to achieve a smaller bending radius of the display module 10, and also helps to reduce the crease effect caused by plastic deformation or creep after multiple bending of the optical layer 500.

[0147] For ease of description, the following Embodiment 1 will be used as an example to illustrate the module 10 including the optical layer 500.

[0148] In some embodiments, the projection of the optical layer 500 in the first direction X is located within the projection of the display panel 200 in the first direction X.

[0149] In this embodiment, before cutting the display panel motherboard 20 and the support film 400, a block-shaped optical layer 500 can be first set above the corresponding panel area 20a. By setting the projection of the optical layer 500 in the first direction X to be within the projection of the display panel 200 in the first direction X, the influence of the optical layer 500 on the cutting process of the display panel motherboard 20 can be effectively reduced, which is beneficial to improving the manufacturing efficiency of the display module 10.

[0150] For example, the projection of the optical layer 500 in the first direction X may coincide with the projection of the display panel 200 in the first direction X; or, the projection area of ​​the optical layer 500 in the first direction X may be smaller than the projection area of ​​the display panel 200 in the first direction X, and the projection edge of the optical layer 500 in the first direction X may be spaced apart from the projection edge of the display panel 200 in the first direction X (not shown in the figure).

[0151] Figure 29 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0152] In some embodiments, such as Figure 29 As shown, the support member 100 also includes an auxiliary support plate 120 disposed on the side of the support plate 110 opposite to the display panel 200. The projection of the display panel 200 in the first direction X is located within the projection of the auxiliary support plate 110 in the first direction X, and / or, the projection of the support plate 110 in the first direction X is located within the projection of the auxiliary support plate 120 in the first direction X.

[0153] For example, the projected area of ​​the auxiliary support plate 120 in the first direction X may be greater than the projected area of ​​the display panel 200 in the first direction X, and the projected edge of the auxiliary support plate 120 in the first direction X may be spaced apart from the projected edge of the display panel 200 in the first direction X; and / or, the projected area of ​​the auxiliary support plate 120 in the first direction X may be greater than the projected area of ​​the support plate 110 in the first direction X, and the projected edge of the auxiliary support plate 120 in the first direction X may be spaced apart from the projected edge of the support plate in the first direction X.

[0154] Optionally, the auxiliary support plate 120 and the support plate can be connected by a third adhesive material G3. For example, the third adhesive material G3 may include pressure-sensitive adhesive, and the auxiliary support plate 120 and the support plate can be connected by a pressure-sensitive adhesive covering the entire surface.

[0155] In this embodiment, the auxiliary support plate 120 can also provide some support for the display panel 200. By setting the projection of the display panel 200 in the first direction X to be within the projection of the auxiliary support plate 120 in the first direction X, and setting the projection of the support plate 110 in the first direction X to be within the projection of the auxiliary support plate 120 in the first direction X, the auxiliary support plate 110 can have a larger size and protrude outward relative to the edges of the display panel 200 and the support plate 110. This allows the auxiliary support plate 120 to make contact with other device structures before the support plate and the display panel 200 when the display module 10 is installed in other device structures. This is beneficial to improving the edge protection of the support plate and the display panel 200 by the auxiliary support plate 120, thereby facilitating the installation of the display module 10.

[0156] In some embodiments, there is a second gap (D2 in the figure can indicate the second gap) between the projection of the edge of the auxiliary support plate 120 in the first direction X and the projection of the edge of the display panel 200 in the first direction X. The second gap is not less than 30 μm and not more than 250 μm.

[0157] By setting the second spacing to be no less than 30μm, the size of the auxiliary support plate 120 is not too small, which helps to improve the protective function of the auxiliary support plate 120. By setting the second spacing to be no more than 250μm, the size of the auxiliary support plate 120 is not too large, which helps to reduce the bezel size of the display module 10 and makes it easier to install the display module 10 into other device structures.

[0158] In some embodiments of this application, the auxiliary support plate 120 has various structural configurations.

[0159] In some examples, the auxiliary support plate 120 may be a single-layer structure. For example, the material of the auxiliary support plate 120 may include metal, resin, etc.

[0160] In other examples, the auxiliary support plate 120 may be a composite structure, formed by stacking multiple layers. For example, the auxiliary support plate 120 may include stacked metal layers, heat dissipation layers, foam layers, and resin layers, so that the auxiliary support plate 120 can have good support performance, while also providing good heat dissipation through the heat dissipation layer and good buffering effect from external impacts through the foam layer.

[0161] Figure 30 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0162] In some embodiments, such as Figure 30 As shown, the auxiliary support plate 120 in at least one of the non-bending region A1 and the bending region has a third functional opening 120a.

[0163] By opening a third functional opening 120a in the auxiliary support plate 120 in the bending region A2, the bending performance of the auxiliary support plate 120 in the bending region A2 is improved. By opening a third functional opening 120a in the auxiliary support plate 120 in the non-bending region A1, the deformation capability of the auxiliary support plate 120 in the non-bending region A1 is improved. This allows the auxiliary support plate 120 to better mitigate the impact force of collisions between the auxiliary support plate 120 and other device structures when the display module 10 is installed in other device structures, through its own deformation.

[0164] Optionally, when at least a portion of the third functional opening 120a is located within the bending region A2, the shape, size, and arrangement of the third functional opening 120a located within the bending region A2 can be set with reference to the shape, size, and arrangement of the first functional opening 110a in any of the foregoing embodiments, so that the shape, size, and arrangement of the third functional opening 120a within the bending region A2 can better meet the support requirements of the auxiliary support plate 120 for the display panel 200 and the bending requirements of the display module 10.

[0165] Optional, such as Figure 30As shown, the non-bending region A1 includes a main support region A11 and an edge region A12 located on the side of the main support region A11 away from the bending region. At least a portion of the third functional opening 120a is located within the edge region A12. Since the edge region A12, located at the edge, is more prone to collision with other device structures than the main support region A11 when the display module 10 is installed within them, by providing at least a portion of the third functional opening 120a within the edge region A12, the auxiliary support plate 120 located within the edge region A12 can have better deformation capability, thereby helping to mitigate the impact force between the auxiliary support plate 120 and other device structures.

[0166] In addition, before cutting the display panel motherboard 20 and the support film 400, a block-shaped auxiliary support plate 120 can be set below the corresponding panel area 20a. By opening a third functional opening 120a in the edge area A12, it is beneficial to reduce the thickness of the auxiliary support plate 120 in the edge area A12. This reduces the impact of material edge carbonization during the cutting process when cutting the display panel motherboard 20, thereby improving the cutting effect of the display panel motherboard 20.

[0167] Optionally, the third functional opening 120a may penetrate the auxiliary support plate 120 (not shown in the figure), so that the auxiliary support plate 120 can have better deformation capacity; or, the third functional opening 120a may not penetrate the auxiliary support plate 120, so that the auxiliary support plate 120 can have better structural strength.

[0168] Optionally, when the third functional opening 120a does not penetrate the auxiliary support plate 120, at least a portion of the third functional opening 120a is formed on the side of the auxiliary support plate 120 facing the display panel 200 (not shown in the figure), and / or, as... Figure 31 As shown, at least part of the third functional opening 120a is opened on the side of the auxiliary support plate 120 away from the display panel 200.

[0169] Figure 31 This is a partial structural schematic diagram of an auxiliary support plate 120 provided in an embodiment of this application.

[0170] Optional, such as Figure 31As shown, the shape of the third functional opening 120a can be configured in various ways. For example, the projection shape of the third functional opening 120a in the first direction X is annular, sawtooth, or zigzag. By reasonably setting the shape of the third functional opening 120a, it is beneficial to improve the deformation capability of the auxiliary support plate 120 when subjected to an external force impact parallel to the plane of the auxiliary support plate 120 in the flattened state of the display module 10. This helps to alleviate the impact force between the auxiliary support plate 120 and other device structures when the display module 10 is installed in other device structures.

[0171] Optionally, the projection shape of the third functional opening 120a in the first direction X is annular, sawtooth, or zigzag. This can refer to the fact that when the display module 10 is in a flattened state, the projection shape of the third functional opening 120a in the first direction X is annular, sawtooth, or zigzag.

[0172] Figure 32 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0173] like Figure 32 As shown, in some embodiments, the display module 10 further includes a protective layer 600 disposed on the side of the support member 100 opposite to the display panel 200, with at least a portion of the protective layer 600 located within the bending region A2. The protective layer 600 covering the support member 100 within the bending region A2 can limit the influence of external dust on the support member 100 within the bending region A2, thereby enabling the support member 100 to have better bending stability.

[0174] Optionally, a portion of the protective layer 600 may also be located within the non-bending area A1, that is, a portion of the protective layer 600 may also cover the support member 100 within the non-bending area A1.

[0175] Optionally, the protective layer 600 located in the bending region A2 may include a metal material layer or a polymer film, so that the protective layer 600 in the bending region A2 can have good bending performance, so that during the bending process of the display module 10, the protective layer 600 can bend together with the support member 100, and the protective layer 600 can be better attached to the support member 100.

[0176] Figure 33 This application also provides a schematic diagram of the structure of a display module 10 according to another embodiment. like Figure 33 As shown, in some embodiments, the display module 10 further includes a first cover plate 700 disposed on the side of the display panel 200 away from the support member 100. The material of the first cover plate 700 includes glass, and the first cover plate 700 in the bending region A2 has a fourth functional opening 700a.

[0177] Optionally, the first cover plate 700 may be located in the bent region A2 and the non-bent region A1. Optionally, the material of the first cover plate 700 may be glass, that is, the material of the first cover plate 700 in both the bent region A2 and the non-bent region A1 may be glass.

[0178] In this embodiment, the first cover plate 700 protects the underlying structure. By including glass in the material of the first cover plate 700, it is less prone to plastic deformation and creep when bending and deforming along with the display panel 200. This effectively reduces creases in the display module 10 (for example, by combining the first cover plate 700 with the aforementioned support plate 110, the crease height of the display module 10 can be kept no greater than 10 μm), and facilitates writing and control by the user using a stylus. Furthermore, the glass material of the first cover plate 700 provides good light transmittance, allowing light emitted from the display panel 200 to pass through and be emitted outwards. The inclusion of a fourth functional opening 700a in the first cover plate 700 within the bending region A2 further enhances its bending performance within the bending region A2.

[0179] Optionally, the display module 10 also includes a second adhesive layer 800 disposed between the first cover plate 700 and the display panel 200, wherein the first cover plate 700 can be connected to the underlying film layer through the second adhesive layer 800.

[0180] Optionally, the material of the second adhesive layer 800 may include a transparent adhesive, thereby enabling the second adhesive layer 800 to have good light transmittance. For example, the second adhesive layer 800 may be a solid optical adhesive.

[0181] In some embodiments, the projection of the first cover plate 700 in the first direction X is located within the projection of the display panel 200 in the first direction X.

[0182] Optionally, the projected area of ​​the first cover plate 700 in the first direction X may be smaller than the projected area of ​​the display panel 200 in the first direction X, and the projected edge of the first cover plate 700 in the first direction X may be spaced apart from the projected edge of the display panel 200 in the first direction X.

[0183] In this optional embodiment, by setting the projection of the first cover plate 700 in the first direction X to be within the projection of the display panel 200 in the first direction X, the first cover plate 700 can have a smaller size than the display panel 200, which can help improve the manufacturing efficiency of the display module 10.

[0184] For example, before cutting the display panel motherboard 20 and the support film 400, a block-shaped first cover plate 700 can be set above the corresponding panel area 20a, so that the first cover plate 700 can provide a certain degree of protection for the panel area 20a. By setting the projection of the first cover plate 700 in the first direction X to be within the projection of the display panel 200 in the first direction X, the arrangement of the first cover plate 700 is less likely to affect the cutting process of the display panel motherboard 20, thereby improving the manufacturing efficiency of the display module 10.

[0185] Optionally, the distance between the projected edge of the first cover plate 700 in the first direction X and the projected edge of the display panel 200 in the first direction X can be no less than 100 μm and no more than 250 μm. By setting the distance between the projected edge of the first cover plate 700 in the first direction X and the projected edge of the display panel 200 in the first direction X to be no less than 100 μm, the size of the first cover plate 700 is not too large, allowing for larger cutting process errors when cutting the display panel mother plate 20, which is beneficial to the fabrication of the display module 10. Furthermore, it also ensures that when the display module 10 is installed into other device structures, the first cover plate 700 has a suitable distance from other device structures, thus facilitating the installation of the display module 10. By setting the distance between the projected edge of the first cover plate 700 in the first direction X and the projected edge of the display panel 200 in the first direction X to be no more than 250 μm, the size of the first cover plate 700 is not too small, allowing the first cover plate 700 to provide better overall protection for the other device structures below.

[0186] In some embodiments, the display module 10 further includes a second protective structure BS2 disposed on the periphery of the first cover plate 700 in a direction perpendicular to the first direction X. The second protective structure BS2 can be used to protect the edge of the first cover plate 700. When the display module 10 is installed into other device structures (e.g., when the display module 10 is installed into a mid-frame), the second protective structure BS2 can provide better protection for the edge of the first cover plate 700, making the first cover plate 700 less likely to be damaged by collision with other device structures, thereby facilitating the installation of the display module 10.

[0187] Optionally, the material of the second protective structure BS2 can be configured in various ways. For example, the material of the second protective structure BS2 may include an adhesive, allowing the second protective structure BS2 to effectively cover the edge of the first cover plate 700 while also providing a certain degree of impact resistance. In a further example, a portion of the second adhesive layer 800 extends to the periphery of the first cover plate 700 in a direction perpendicular to the first direction X and is reused as the second protective structure BS2. This allows the second protective structure BS2 to be prepared simultaneously with the preparation of the second adhesive layer 800 without requiring a separate additional process, thereby improving the manufacturing efficiency of the display module 10.

[0188] Optionally, the projection of the second protective structure BS2 in the first direction X is located within the projection of the display panel 200 in the first direction X, so that the second protective structure BS2 is not likely to protrude outward relative to the edge of the display panel 200, so that when the display module 10 is installed into other device structures, the second protective structure BS2 is not likely to interfere with the installation and movement of the display module 10.

[0189] In some embodiments of this application, the shape, size and arrangement of the fourth functional opening 700a located in the bending region A2 can be set with reference to the shape, size and arrangement of the first functional opening 110a in any of the foregoing embodiments, so that the shape, size and arrangement of the fourth functional opening 700a in the bending region A2 can better meet the support requirements of the auxiliary support plate 120 for the display panel 200 and the bending requirements of the display module 10.

[0190] Optionally, the fourth functional opening 700a may penetrate through the first cover plate 700 (not shown in the figure), so that the first cover plate 700 in the bending area A2 can have better bending performance; or, the fourth functional opening 700a may not penetrate through the first cover plate 700, so that the first cover plate 700 in the bending area A2 can have better structural strength.

[0191] Optionally, at least part of the fourth functional opening 700a is formed on the side of the first cover 700 facing the display panel 200 (e.g. Figure 33 As shown), and / or, at least part of the fourth functional opening 700a is opened on the side of the first cover plate 700 opposite to the display panel 200 (not shown in the figure).

[0192] Optionally, based on the aforementioned principle of setting the first and second dimensions in the first functional opening 110a, when a portion of the fourth functional openings 700a are opened on the side of the first cover plate 700 facing the display panel 200, and another portion of the fourth functional openings 700a are opened on the side of the first cover plate 700 away from the display panel 200, the dimension of a single fourth functional opening 700a on the side of the first cover plate 700 facing the display panel 200 in the first direction X may be different from the dimension of a single fourth functional opening 700a on the side of the first cover plate 700 away from the display panel 200 in the first direction X, so that the first cover plate 700 can have different bending capabilities according to the bending requirements of the display module 10.

[0193] Optionally, based on the aforementioned principle of setting the third and fourth dimensions in the first functional opening 110a, when a portion of the fourth functional openings 700a are opened on the side of the first cover plate 700 facing the display panel 200, and another portion of the fourth functional openings 700a are opened on the side of the first cover plate 700 away from the display panel 200, the dimension of a single fourth functional opening 700a on the side of the first cover plate 700 facing the display panel 200 in the second direction Y can be different from the dimension of a single fourth functional opening 700a on the side of the first cover plate 700 away from the display panel 200 in the second direction Y, so that the first cover plate 700 can have different bending capabilities according to the bending requirements of the display module 10.

[0194] Optionally, the fourth functional opening 700a does not penetrate the first cover plate 700. The fourth functional opening 700a can be opened on the side of the first cover plate 700 facing the display panel 200, so that the side of the first cover plate 700 away from the display panel 200 can have better flatness, which is beneficial to improving the user's touch display module 10 experience.

[0195] Figure 34 This is a partial cross-sectional schematic diagram of a first cover plate 700 provided in an embodiment of this application.

[0196] In some embodiments, such as Figure 34 As shown, the fourth functional opening 700a includes a third opening 700aa, and the size of the third opening 700aa gradually decreases in the first direction X along the direction from the bent region A2 to the non-bent region A1.

[0197] For example, the size of the third opening 700aa gradually decreases in the first direction X along the direction from the bent region A2 to the non-bent region A1. This can refer to the fact that when the display module 10 is in a flattened state, the size of the third opening 700aa gradually decreases in the first direction X along the direction from the bent region A2 to the non-bent region A1.

[0198] Optionally, there are several ways to achieve a gradual decrease in the size of the third opening 700aa in the first direction X, along the direction from the bent region A2 to the non-bent region A1. As an example, such as... Figure 34 As shown, the surface of the first cover plate 700 facing the third opening 700aa may include two planes whose extension directions intersect, and the extension directions of both planes intersect the first direction X. As another example, the surface of the first cover plate 700 facing the third opening 700aa may be an arc surface (not shown in the figure).

[0199] In these embodiments, during the bending process of the first cover plate 700, the degree of bending of the first cover plate 700 is smaller at the position closer to the non-bending region A1 within the bending region A2 (for example, during the bending process of the first cover plate 700, the bending radius of the first cover plate 700 is larger at the position closer to the non-bending region A1 within the bending region A2), that is, the degree of bending of the first cover plate 700 located at the center position within the bending region A2 is greater than the degree of bending of the first cover plate 700 located at the edge position within the bending region A2.

[0200] Therefore, by setting the third opening 700aa to gradually decrease in size in the first direction X along the direction from the bending region A2 to the non-bending region A1, the thickness of the first cover plate 700 with a greater degree of bending in the bending region A2 can be less than the thickness of the first cover plate 700 with a lesser degree of bending in the bending region A2 during the bending process of the first cover plate 700. This is beneficial to improving the bending performance of the first cover plate 700 in the bending region A2, while the location of the first cover plate 700 with a greater thickness in the bending region A2 can have better structural strength, and it is also beneficial to improve the support effect of the first cover plate 700 on the display panel 200.

[0201] Optionally, at least one third opening 700aa has a dimension in the second direction Y that is equal to the dimension of the bent region A2 in the second direction Y.

[0202] For example, the fact that at least one third opening 700aa has the same size in the second direction Y as the bending region A2 in the second direction Y can refer to the fact that when the display module 10 is in a flattened state, at least one third opening 700aa has the same size in the second direction Y as the bending region A2 in the second direction Y.

[0203] In this embodiment, by setting at least one third opening 700aa with a size in the second direction Y equal to the size of the bending region A2 in the second direction Y, the first cover plate 700 in the bending region A2 can be provided with a third opening 700aa, thereby enabling the first cover plate 700 in the bending region A2 to have good bending performance as a whole.

[0204] Optionally, at least one third opening 700aa may have a dimension in the third direction Z that is equal to that of the first cover plate 700 in the third direction Z, so that the third opening 700aa may have a larger dimension in the third direction Z, thereby facilitating the bending of the first cover plate 700 along the pivot extending in the third direction Z.

[0205] Figure 35 This is a partial cross-sectional schematic diagram of a first cover plate 700 provided in another embodiment of this application.

[0206] like Figure 35 As shown, in some embodiments, the fourth functional opening 700a includes a fourth opening 700ab, the first cover plate 700 includes a second body portion 710 and a second protrusion 720 protruding relative to the second body portion 710 along a first direction X, at least one fourth opening 700ab is disposed around the second protrusion 720, and / or the second protrusion 720 is located between adjacent fourth openings 700ab.

[0207] Optionally, when the display module 10 is in a flattened state, the width of the fourth opening 700ab in the second direction Y may be smaller than the width of the third opening 700aa in the second direction Y.

[0208] In this embodiment, by setting a smaller fourth opening 700ab, it is beneficial to improve the bending performance of the first cover plate 700 in the bending area A2, while also ensuring that the structural strength of the first cover plate 700 in the bending area A2 is not too low.

[0209] Figure 36 This is a partial structural schematic diagram of a first cover plate 700 provided in an embodiment of this application.

[0210] Optional, such as Figure 36 As shown, the shape of the fourth opening 700ab can be configured in various ways. For example, the projection shape of the fourth opening 700ab in the first direction X is annular, serrated, or zigzag.

[0211] Optionally, the projection shape of the fourth opening 700ab in the first direction X is annular, sawtooth, or zigzag. This can refer to the fact that when the display module 10 is in a flattened state, the projection shape of the fourth opening 700ab in the first direction X is annular, sawtooth, or zigzag.

[0212] Optionally, when the display module 10 is in a flattened state, the multiple fourth openings 700ab, which are annular in projection shape in the first direction X, can be interconnected to form a grid.

[0213] Figure 37 This is a partial cross-sectional schematic diagram of a first cover plate 700 provided in another embodiment of this application.

[0214] like Figure 37 As shown, in some embodiments, there are multiple fourth openings 700ab, which are spaced apart in the second direction Y. Among two adjacent fourth openings 700ab in the second direction Y, the size of the fourth opening 700ab closer to the non-bending region A1 in the second direction Y is smaller than the size of the fourth opening 700ab farther from the non-bending region A1 in the second direction Y.

[0215] Optionally, the arrangement of multiple fourth openings 700ab at intervals in the second direction Y can refer to the arrangement of multiple fourth openings 700ab at intervals in the second direction Y when the display module 10 is in a flattened state. Optionally, the size of the fourth opening 700ab in the second direction Y can refer to the size of the fourth opening 700ab in the second direction Y when the display module 10 is in a flattened state.

[0216] In this embodiment, during the bending process of the first cover plate 700, the degree of bending of the first cover plate 700 is smaller when it is closer to the non-bending area A1 within the bending area A2. That is, the degree of bending of the first cover plate 700 located at the center of the bending area A2 is greater than the degree of bending of the first cover plate 700 located at the edge of the bending area A2. Therefore, by setting the fourth opening 700ab closer to the non-bending region A1 in the second direction Y to be smaller in the second direction Y than the fourth opening 700ab farther from the non-bending region A1, during the bending process of the first cover plate 700, the width of the fourth opening 700ab at the first cover plate 700 with a greater degree of bending in the bending region A2 is larger, while the width of the fourth opening 700ab at the first cover plate 700 with a lesser degree of bending in the bending region A2 is smaller. This is beneficial to improving the bending performance of the first cover plate 700 in the bending region, while also ensuring that the structural strength of the first cover plate 700 is not too low.

[0217] Please continue to refer to Figure 37 In some embodiments, there are multiple second protrusions 720, which are spaced apart in the second direction Y. Among two adjacent second protrusions 720 in the second direction Y, the size of the second protrusion 720 closer to the non-bending region A1 in the second direction Y is larger than the size of the second protrusion 720 farther from the non-bending region A1 in the second direction Y.

[0218] Optionally, the plurality of second protrusions 720 are spaced apart in the second direction Y, which may refer to the plurality of second protrusions 720 being spaced apart in the second direction Y when the display module 10 is in a flattened state. Optionally, the dimension of the second protrusion 720 in the second direction Y may refer to the dimension of the second protrusion 720 in the second direction Y when the display module 10 is in a flattened state.

[0219] In this embodiment, similar to the analysis in the previous embodiment, by setting two adjacent second protrusions 720 in the second direction Y, the size of the second protrusion 720 closer to the non-bending region A1 in the second direction Y is larger than the size of the second protrusion 720 farther from the non-bending region A1 in the second direction. This makes it so that during the bending process of the first cover plate 700, the width of the second protrusion 720 at the first cover plate 700 with a larger degree of bending in the bending region A2 is smaller, while the width of the second protrusion 720 at the first cover plate 700 with a smaller degree of bending in the bending region A2 is larger. This is beneficial to improving the bending performance of the first cover plate 700 in the bending region, and also to ensuring that the structural strength of the first cover plate 700 is not too low.

[0220] Figure 38 This is a partial cross-sectional schematic diagram of a first cover plate provided in another embodiment of this application.

[0221] like Figure 38 As shown, in some embodiments, there are multiple fourth openings 700ab, which are spaced apart in the second direction Y. Among two adjacent fourth openings 700ab in the second direction Y, the size of the fourth opening 700ab closer to the non-bending region A1 in the first direction X is smaller than the size of the fourth opening 700ab farther from the non-bending region in the first direction X.

[0222] Optionally, the dimension of the fourth opening 700ab in the first direction X may refer to the dimension of the fourth opening 700ab in the first direction X when the display module 10 is in a flattened state.

[0223] In this embodiment, similar to the analysis in the previous embodiment, by setting the fourth opening 700ab closer to the non-bending region A1 in the second direction Y to have a smaller size in the first direction X than the fourth opening 700ab farther from the non-bending region A1 in the first direction X, during the bending process of the first cover plate 700, the fourth opening 700ab at the first cover plate 700 with a larger degree of bending in the bending region A2 has a larger depth, while the fourth opening 700ab at the first cover plate 700 with a smaller degree of bending in the bending region A2 has a smaller depth. This is beneficial to improving the bending performance of the first cover plate 700 in the bending region A2, while also ensuring that the structural strength of the first cover plate 700 is not too low.

[0224] In some embodiments of this application, the fourth functional opening 700a may include only the third opening 700aa; or, the fourth functional opening 700a may include only the fourth opening 700ab; or, the fourth functional opening 700a may include both the third opening 700aa and the fourth opening 700ab.

[0225] Optionally, when the fourth functional opening 700a includes the third opening 700aa and the fourth opening 700ab, the third opening 700aa and the fourth opening 700ab can be respectively disposed on both sides of the first cover plate 700 in the first direction X, so that the bending ability of the first cover plate 700 when bending in different directions can be different.

[0226] Optionally, the first cover plate 700 may have a suitable thickness, which is beneficial to improving the structural strength of the first cover plate 700, thereby improving the anti-pen-drop performance of the display module 10.

[0227] For example, the thickness of the first cover plate 700 at the location where the fourth functional opening 700a is not provided (e.g., the thickness of the first cover plate 700 in the non-bending region A1) may be no less than 30 μm and no more than 120 μm. The thickness of the first cover plate 700 at the location corresponding to the fourth functional opening 700a may be no less than 15 μm and no more than 120 μm (e.g., at the location corresponding to the third opening 700aa, the thickness of the first cover plate 700 in the bending region A2 may be no less than 15 μm and no more than 120 μm; or for example, at the location corresponding to the fourth opening 700ab, the thickness of the second main body portion 710 in the bending region A2 may be no less than 15 μm and no more than 40 μm).

[0228] Figure 39 This is a schematic diagram of the structure of a display module 10 provided in another embodiment of this application.

[0229] In some embodiments, the display module 10 may further include a second cover plate 900 disposed on the side of the first cover plate 700 opposite to the display panel 200, the second cover plate 900 providing further protection for the underlying structure.

[0230] Optionally, the material of the second cover plate 900 may include glass.

[0231] Optionally, the second cover plate 900 and the first cover plate 700 can be connected by a fourth adhesive material G4. For example, the fourth adhesive material G4 may include solid optical adhesive, and the second cover plate 900 and the first cover plate 700 can be connected by a solid optical adhesive covering the entire surface.

[0232] Optionally, the display module 10 may also include an ink material INK disposed on the side of the second cover plate 900 facing the display panel 200 (for example, the ink material INK may be located between the second cover plate 900 and the fourth adhesive material G4), and the ink material INK may be located in the edge region A12. The ink material INK can be used to shield the device structures (such as circuit structures or metal traces) located in the edge region A12 of the display panel 200, so that the device structures in the edge region A12 are not easily noticed by the user after the light is reflected.

[0233] Optionally, the display module 10 may also include a protective film PF disposed on the side of the second cover plate 900 opposite to the display panel 200, the protective film PF being used to protect the second cover plate 900.

[0234] Optionally, the protective film PF and the second cover plate 900 can be connected by a fifth adhesive material G5. For example, the fifth adhesive material G5 may include solid optical adhesive, and the protective film PF and the second cover plate 900 can be connected by solid optical adhesive covering the entire surface.

[0235] Figure 40 This is a schematic diagram of the structure of a support plate 110 provided in an embodiment of this application.

[0236] like Figure 40 As shown, in some embodiments, the support plate 110 includes a first support portion 1101 located in the bending region A2 and a second support portion 1102 located in the non-bending region A1. The first support portion 1101 has at least one edge recessed relative to the second support portion 1102 in the third direction Z to form a first groove structure 110b.

[0237] Optionally, the shape of the first groove structure 110b can be configured in various ways. For example, when the display module 10 is in a flattened state, the projection shape of the first groove structure 110b in the first direction X can be a semi-circle, a semi-ellipse, a polygon, or other irregular shape.

[0238] In this embodiment, by providing a first groove structure 110b at the edge of the first support portion 1101 located in the bending region A2, the first support portion 1101 with its recessed edge is less likely to be directly subjected to external force when the display module 10 is subjected to external force (e.g., when the display module 10 falls and collides), compared to the second support portion 1102, thus making the first support portion 1101 less likely to be damaged.

[0239] For example, when the first support portion 1101 has a first functional opening 110a, the structural strength of the first support portion 1101 is easily affected. Therefore, by providing a first groove structure 110b at the edge of the first support portion 1101, the possibility of the first support portion 1101 being damaged by external force impact can be better reduced, thereby enabling the support plate 110 as a whole to have better impact resistance.

[0240] Figure 41 This is a schematic diagram of the structure of a first cover plate 700 provided in an embodiment of this application.

[0241] like Figure 41 As shown, in some embodiments, the first cover plate 700 includes a first cover plate portion 701 located in the bending region A2 and a second cover plate portion 702 located in the non-bending region A1. The first cover plate portion 701 has at least one edge recessed relative to the second cover plate portion 702 in the third direction Z to form a second groove structure 700b.

[0242] Optionally, the shape of the second recess structure 700b can be configured in various ways. For example, when the display module 10 is in a flattened state, the projection shape of the second recess structure 700b in the first direction X can be a semi-circle, a semi-ellipse, a polygon, or other irregular shape.

[0243] In this embodiment, by providing a second groove structure 700b at the edge of the first cover portion 701 located in the bending region A2, when the display module 10 is subjected to an external force impact (for example, when the display module 10 falls and collides), the first cover portion 701 with a recessed edge is less likely to be directly subjected to external force compared to the second cover portion 702, thereby making the first cover portion 701 less likely to be damaged.

[0244] For example, when the first cover plate portion 701 has a fourth functional opening 700a, the structural strength of the first cover plate portion 701 is easily affected. Therefore, by providing a second groove structure 700b at the edge of the first cover plate portion 701, the possibility of the first cover plate portion 701 being damaged by external force impact can be better reduced, thereby enabling the support plate 110 as a whole to have better impact resistance.
