[0011] The following describes the accompanying drawings that may be used in the description of the embodiments. The accompanying drawings described below represent only a few embodiments of the present application, and those skilled in the art can obtain other drawings based on these accompanying drawings without any creative work.

[0012] The embodiments of this application will be described below with reference to the accompanying drawings in the embodiments of this application, but the embodiments described are only a selection of embodiments of this application. All other embodiments that a person skilled in the art could obtain without creative work based on the embodiments in this application are all included within the scope of protection of this application.

[0013] In the following description, many details will be provided to help understand this application, but this application can also be implemented in other ways different from those described herein, and a person skilled in the art may apply them by analogy to the extent that it does not contradict the spirit of this application.

[0014] Typically, a display device comprises a middle frame and a display assembly. Here, the display assembly includes a cover plate and a display module, with the display module located on the backlight side of the cover plate. In practical applications, the display assembly is assembled as a display device by overlapping connections to the middle frame via the cover plate.

[0015] As shown in Figure 1, in a direction perpendicular to the plane on which the display device is located, the middle frame includes a first part 01 and a second part 02. Here, the inner diameter of the first part 01 is larger than that of the second part 02, and a stepped surface is formed in the boundary region between the first part 01 and the second part 02. The cover plate 03 is overlapped and connected to the stepped surface via a filler 04 and assembled with the middle frame. In this assembly method, the distance D1 between the end of the display assembly facing the middle frame and the surface of the middle frame away from the display assembly is relatively large, resulting in a relatively large bezel area for the display device shown in Figure 1, and furthermore, a wide black border corresponding to the bezel area in the display device shown in Figure 1, which affects the user experience.

[0016] Embodiments of the present invention provide a display device, as shown in Figure 2, comprising a display assembly 10 and a middle frame 20. The display assembly 10 includes a cover plate 11, a display module 12, and a sealing portion 13. The cover plate 11 has a light-emitting side and a backlight side. The display module 12 is located on the backlight side of the cover plate 11. At least a portion of the sealing portion 13 is located on the backlight side of the cover plate 11. The sealing portion 13 at least partially surrounds the display module 12.

[0017] The middle frame 20 is provided with a support base 21 on at least a portion of its circumferential direction. The support base 21 is provided on the side of the display module 12 away from the cover plate 11. The support base 21 and the display module 12 have a first overlapping region 30 in the thickness direction Y of the cover plate 11.

[0018] As an option, in one embodiment of the present invention, the cover plate 11 is a glass cover plate, and the sealing portion 13 is an adhesive curing portion, that is, it is formed by curing an adhesive.

[0019] In this embodiment, the sealing portion 13 may be partially located on the backlight side of the cover plate 11, or it may be entirely located on the backlight side of the cover plate 11. The sealing portion 13 may be partially surrounding the display module 12, or it may be entirely surrounding the display module 12. The method of installing the sealing portion 13 in this application may be determined on a case-by-case basis.

[0020] In the display device according to the embodiment of the present invention, the support base 21 and the display module 12 have a first overlapping region 30 in the thickness direction Y of the cover plate 11. As a result, the support base 21 and the display module 12 partially overlap, reducing the distance D2 between the end of the display module 12 facing the middle frame 20 and the surface of the middle frame 20 facing the display module 12 in a direction parallel to the plane on which the cover plate 11 is located. Furthermore, the distance D3 between the end of the display module 12 facing the middle frame 20 and the surface of the middle frame 20 away from the display module 12 is reduced. This reduces the area of ​​the bezel region of the display device in a direction parallel to the plane on which the cover plate 11 is located, adapting to the trend of narrow bezels.

[0021] As an option, in one embodiment of the present invention, the ratio of the length of the first overlapping region 30 to the length of the support base 21 in the first direction X is in the range of 0.1 to 0.4. This prevents the gap between the middle frame 20 and the display module 12 from being too small, which would cause the swinging of the middle frame 20 to damage the display module 12, while also preventing the gap between the middle frame 20 and the display module 12 from being too large, which would increase the bezel area of ​​the display device and be detrimental to achieving a narrow bezel.

[0022] Exemplary, in one embodiment of the present invention, the ratio of the length of the first overlapping region 30 to the length of the support base 21 in the first direction X is in the range of 0.15 to 0.3. This makes it possible to achieve both that the oscillation of the middle frame 20 does not damage the display module 12 and that the display device has a narrow bezel, thereby achieving a good balance between preventing damage to the display module 12 from the oscillation of the middle frame 20 and the display device having a narrow bezel.

[0023] Optionally, in one embodiment of the present invention, the length of the first overlapping region 30 in the first direction X is 0.5 millimeters (mm) or more. This provides the support base 21 with good support strength for the display module 12.

[0024] Exemplary, in one embodiment of the present invention, the length of the support base 21 in the first direction X is 0.8 mm or more. This ensures that the support base 21 has good support strength for the display module 12.

[0025] Exemplary, in one embodiment of the present invention, as shown in Figure 3, the display module 12 includes a stacked display panel 121, a support portion 122, and a composite layer 123. Here, the composite layer 123 has a plurality of functional layers, and the display panel 121 has a curved panel portion 1211 on one side in a first direction X. Here, the first direction X is parallel to the plane on which the cover plate 11 is located and perpendicular to the thickness direction Y of the cover plate 11.

[0026] In one embodiment of the present invention, as shown in Figure 4, the support base 21 has an overlapping region with the curved panel portion 1211 of the display panel 121 in the display module 12, while the composite layer 123 and the support portion 122 do not overlap. This reduces the length of the support base 21 that extends toward the backlight side of the display module 12, providing more design space for the internal structure of the display device. In this embodiment, the overlapping region between the support base 21 and the curved panel portion 1211 is the first overlapping region 30.

[0027] In another embodiment of the present invention, as shown in Figure 3, the support base 21 not only has an overlapping region with the curved panel portion 1211 of the display panel 121 in the display module 12, but also has an overlapping region with the composite layer 123 and the support portion 122. This increases the length of the support base 21 that extends toward the backlight side of the display module 12, and decreases the distance D2 between the end of the display module 12 facing the middle frame 20 and the surface of the middle frame 20 facing the display module 12, in a direction parallel to the plane where the cover plate 11 is located.

[0028] Furthermore, the distance D3 between the end of the display module 12 facing the middle frame 20 and the surface of the middle frame 20 away from the display module 12 is reduced. This reduces the area of ​​the bezel region of the display device in a direction parallel to the plane on which the cover plate 11 is located, thereby achieving a narrow bezel. In this embodiment, the overlapping region between the support base 21 and the curved panel portion 1211, and the overlapping region between the support base 21 and at least one of the composite layer 123 or the support portion 122 constitute the first overlapping region 30.

[0029] Optionally, in one embodiment of this application, as shown in Figures 3 and 5, the composite layer 123 has a length smaller than the support portion 122 in the first direction X. Exemplarily, in one embodiment of this invention, the support base 21 and the composite layer 123 have a second overlapping region 31. This reduces the bezel area of ​​the display device and achieves a narrow bezel, while the support base 21 provides a certain support function to the composite layer 123 in the thickness direction Y of the cover plate 11, thereby improving the stability of the display module 12 in the thickness direction Y of the cover plate 11.

[0030] In the above embodiment, the multiple functional layers included in the composite layer 123 may have the same size in a first direction as shown in Figure 3, or they may be different as shown in Figure 5. Optionally, in one embodiment of the present application, the support base 21 and the composite layer 123 have a second overlapping region 31 in the thickness direction Y of the cover plate 11, and the second overlapping region 31 includes an overlapping region 311 that the support base 21 and at least one functional layer in the composite layer 123 have in the thickness direction Y of the cover plate 11, so as to achieve overlap between the support base 21 and the composite layer 123.

[0031] Exemplary, in one embodiment of the present application, the functional layer in the composite layer 123 is a first functional layer 1231. In a first direction X, the first functional layer 1231 is the longest functional layer in the composite layer 123. That is, the distance between the first functional layer 1231 and the arc apex of the curved panel portion 1211 is smaller than the distance between the other functional layers in the composite layer 123 and the arc apex of the curved panel portion 1211.

[0032] In one embodiment of the present invention, as shown in Figure 6, the support base 21 has an overlapping region 311 only with the first functional layer 1231 in the composite layer 123, thereby achieving both the support strength of the support base 21 for the display module 12 and the area occupied by the support base 21 inside the display device. In another embodiment of the present invention, as shown in Figure 5, the support base 21 not only has an overlapping region 311 with the first functional layer 1231 in the composite layer 123, but also has an overlapping region 312 with other functional layers in the composite layer 123, thereby increasing the support strength of the support base 21 for the display module 12 and improving the stability of the display module 12 in the thickness direction Y of the cover plate 11.

[0033] As an option, in one embodiment of the present invention, as shown in Figure 5, the support base 21 and at least two functional layers in the composite layer 123 overlap at least partially in the thickness direction Y of the cover plate 11. By increasing the number of functional layers in the composite layer 123 that overlap with the support base 21, the support strength of the support base 21 to the display module 12 can be increased, and the stability of the display module 12 in the thickness direction Y of the cover plate 11 can be improved.

[0034] Exemplary, in one embodiment of the present application, the range of the value of the second overlapping region 31 in the first direction X is 0.2 to 0.4 mm. This allows the support base 21 to exert a good support effect on the composite layer 123, thereby improving the stability of the display module 12 in the thickness direction Y of the cover plate 11.

[0035] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 6, the support base 21 has an end 211 on the side away from the middle frame 20, and the curved panel portion 1211 is located between the middle frame 20 and the end 211 of the support base 21 on the side away from the middle frame 20 along the first direction X. That is, in this embodiment, the projection of the curved panel portion 1211 on the plane where the cover plate 11 is located is located within the projection range of the support base 21 on the plane where the cover plate 11 is located. This reduces the area of ​​the bezel region of the display device and realizes a narrow bezel, while maximizing the support function of the support base 21 on the curved panel portion 1211 and improving the stability of the curved panel portion 1211 in the thickness direction Y of the cover plate 11.

[0036] As an example, in one embodiment of the present invention, as shown in Figure 6, in the first direction X, the end 211 of the support base 21 that is away from the middle frame 20 is located on one side of the end of the curved panel portion 1211 that is away from the middle frame 20, thereby ensuring the support effect of the support base 21 on the curved panel portion 1211.

[0037] In another embodiment of the present invention, as shown in Figure 4, in the first direction X, the end 211 of the support base 21 away from the middle frame 20 is flush with the end of the curved panel portion 1211 away from the middle frame 20 in the thickness direction Y of the cover plate 11. This ensures the support effect of the support base 21 on the curved panel portion 1211 while shortening the length of the support base 21 in the first direction X.

[0038] In one embodiment of the present invention, as shown in Figure 7, an arc apex 12110 is provided on the curved panel portion 1211. The distance D4 between the arc apex 12110 and the side of the middle frame 20 closer to the curved panel portion 1211 is smaller than the distance D5 between the arc apex 12110 and the end 211 of the support base 21 that is further away from the middle frame 20. This increases the support strength of the support base 21 for the display module 12.

[0039] In another embodiment of the present invention, as shown in Figure 8, the curved panel portion 1211 is provided with an arc apex 12110, and the distance D4 between the arc apex 12110 and the side of the middle frame 20 closer to the curved panel portion 1211 may be greater than the distance D5 between the arc apex 12110 and the end 211 of the support base 21 that is further away from the middle frame 20. This shortens the length of the support base 21 in the first direction X, thereby reducing the space occupied by the support base 21 inside the display device.

[0040] Based on any of the above embodiments, in one embodiment of the present application, the composite layer 123 includes at least one or more of a metal layer, an adhesive layer, copper foil, foamed cotton, and graphite. The material of the composite layer 123 in the present application may be determined according to the requirements for use of the composite layer 123 in the display device.

[0041] Exemplary, in one embodiment of the present application, as shown in Figures 9 and 10, Figure 10 is a schematic diagram showing the unfolded state of the display assembly 10 in Figure 9. In this embodiment, the composite layer 123 includes copper foil 1232 laminated in the thickness direction Y of the cover plate 11, foamed cotton 1233, first graphite 1234, and double-sided tape 1235. Here, the copper foil 1232 is used to provide strength protection, the foamed cotton 1233 is used to provide cushioning, the first graphite 1234 is used to provide heat dissipation, and the double-sided tape 1235 is used to achieve adhesion between the first graphite 1234 and the support portion 122.

[0042] Exemplary, in one embodiment of the present invention, in the thickness direction Y of the cover plate 11, the thickness of the copper foil 1232 is 0.05 mm, the thickness of the foamed cotton 1233 is 0.1 mm, the thickness of the graphite 1234 is 0.02 mm, the thickness of the double-sided tape 1235 is 0.03 mm, and when the display assembly 10 is unfolded, the width W of the curved panel portion 1211 in the first direction X is 1 mm.

[0043] In another embodiment of the present invention, as shown in Figure 11, the composite layer 123 includes a stainless steel plate 1236 laminated in the thickness direction Y of the cover plate 11, a second graphite 1237, and a thin film 1238. Here, the stainless steel plate 1236 is used to provide strength protection, the second graphite 1237 is used to provide heat dissipation, and the thin film 1238 is used to absorb small amounts of electromagnetic waves emitted from the display panel 121 and to reduce interference between the electromagnetic waves emitted from the display panel 121 and the radio frequency signals of the display device.

[0044] Based on any of the above embodiments, in one embodiment of the present application, as subsequently shown in Figures 9 and 11, the display assembly 10 further includes a polarizing plate 124 located between the display panel 121 and the cover plate 11 to modulate the light rays irradiated onto the display device from the external environment and reduce interference from ambient light.

[0045] Based on any of the above embodiments, in one embodiment of the present application, the curved panel portion 1211 has an arc apex 12110, and the arc apex 12110 and the middle frame 20 have a first set interval in the first direction X. Referring to the distance D4 shown in Figure 8, the first set interval is in the range of 0.3 mm to 0.6 mm. That is, the value of D4 is in the range of 0.3 mm to 0.6 mm. This prevents the middle frame 20 from vibrating in the first direction X due to an applied force and damaging the arc apex 12110, while achieving a narrow bezel for the display device.

[0046] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 8, the side of the sealing portion 13 away from the curved panel portion 1211 is joined to the side of the middle frame 20 closer to the curved panel portion 1211. This fixes the position of the sealing portion 13 in the first direction X and reduces the probability of the sealing portion 13 swinging, thereby reducing the probability of damage to the arc apex 12110 of the curved panel portion 1211 due to the swinging of the sealing portion 13.

[0047] Exemplary, in one embodiment of the present invention, the sealing portion 13 is an adhesive portion and is formed by the curing of the adhesive. As a result, the sealing portion 13 has a certain degree of flexibility, and the display device, through the sealing portion 13, cushions the impact force on the arc apex 12110 of the curved panel portion 1211 when the middle frame 20 is subjected to an impact, thereby reducing the probability that the arc apex 12110 of the curved panel portion 1211 will be damaged.

[0048] Optionally, in one embodiment of the present invention, the sealing portion 13 is manufactured by a low injection pressure over-molding (LIPO) process. This allows the shape of the sealing portion 13 to be set and enables better bonding to the surface of the middle frame 20 facing the curved panel portion 1211.

[0049] As shown in Figure 12, in one embodiment of the present invention, at least one reinforcing portion 22 is provided on the side of the middle frame 20 closest to the curved panel portion 1211. This enhances the degree of bonding between the side of the middle frame 20 closest to the curved panel portion 1211 and the side of the sealing portion 13 away from the curved panel portion 1211, thereby strengthening the relative positional stability between the middle frame 20 and the sealing portion 13.

[0050] As an example, in one embodiment of the present invention, as shown in Figure 12, the reinforcing portion 22 is a projection, and correspondingly, a groove is provided on the side of the sealing portion 13 away from the curved panel portion 1211. This combination of projection and groove improves the degree of bonding between the side of the middle frame 20 closer to the curved panel portion 1211 and the side of the sealing portion 13 away from the curved panel portion 1211.

[0051] In another embodiment of the present invention, as shown in Figure 13, the reinforcing portion 22 is a groove, and correspondingly, a projection is provided on the side of the sealing portion 13 away from the curved panel portion 1211. This combination of projection and groove improves the degree of bonding between the side of the middle frame 20 closer to the curved panel portion 1211 and the side of the sealing portion 13 away from the curved panel portion 1211.

[0052] In some embodiments, one reinforcing portion 22 may be provided on the side of the middle frame 20 closer to the curved panel portion 1211, or multiple reinforcing portions 22 may be provided, and the same number of compatible structures as the reinforcing portions 22 may be arranged on the side of the sealing portion 13 further away from the curved panel portion 1211.

[0053] Optionally, based on any of the above embodiments, in one embodiment of the present application, the reinforcing portion 22 is formed by the curing of an adhesive. This allows the reinforcing portion 22 to have a certain degree of flexibility, improving the degree of bonding between the middle frame 20 and the sealing portion 13, while reducing the interaction force between the middle frame 20 and the sealing portion 13.

[0054] As an option, in one embodiment of the present invention, the reinforcement portion 22 is manufactured by a low-pressure injection molding (LIPO) process. This allows the shape of the reinforcement portion 22 to be set, and enables better bonding between the surface of the middle frame 20 facing the curved panel portion 1211 and the surface of the sealing portion 13 away from the curved panel portion 1211.

[0055] For example, in one embodiment of the present invention, the adhesive material for the reinforcement portion 22 may be an epoxy resin adhesive, acrylic acid, or polyurethane.

[0056] In the above embodiment, the reinforcing portion 22 surrounds a portion of the side surface of the display module 12 in the circumferential direction. Exemplarily, the reinforcing portion 22 may surround one side surface of the display module 12 in the circumferential direction, or it may surround two adjacent sides of the display module 12, as long as it does not affect the assembly of the cover plate 11 and the middle frame 20.

[0057] In another embodiment of the present invention, as shown in Figure 14, an inclined surface 131 is provided on the side of the sealing portion 13 away from the curved panel portion 1211. The inclined surface 131 and the side of the middle frame 20 closer to the curved panel portion 1211 form a first angle α. This allows the contact point between the inclined surface 131 and the middle frame 20 to be used to position the assembly position of the middle frame 20 and the display assembly 10, thereby improving the positioning accuracy during assembly of the middle frame 20 and the display assembly 10.

[0058] In one embodiment of the present invention, as shown in Figure 15, a joint portion 14 is provided between the middle frame 20 and the inclined surface 131 of the sealing portion 13. By utilizing the joint portion 14, the gap between the sealing portion 13 and the middle frame 20 is filled, reducing the probability of the sealing portion 13 shaking, thereby reducing the probability of the sealing portion 13 peeling off.

[0059] Optionally, in one embodiment of the present invention, the range of the first angle α between the inclined surface 131 and the side of the middle frame 20 closer to the curved panel portion 1211 may be 5° to 15°. If the first angle α is too small, it is possible to avoid difficulty in positioning using the inclination point of the inclined surface 131. At the same time, if the first angle α is too large, it is possible to avoid a loss of the protective effect of the sealing portion 13 on the side of the curved panel portion 1211 facing the middle frame 20. The unit of angle is degrees, and is represented by the symbol °.

[0060] In actual applications, an inclined surface is also provided on the side of the sealing portion 13 that is away from the middle frame 20. Furthermore, the inclined surface on the side of the sealing portion 13 that is away from the middle frame 20 and the inclined surface on the side of the sealing portion 13 that is away from the curved panel portion 1211 have different angles of inclination.

[0061] As an option, in one embodiment of the present invention, the angle between the inclined surface of the sealing portion 13 on the side away from the middle frame 20 and the middle frame 20 is 15°.

[0062] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figures 16 to 18, at least one of at least one hole 15 and at least one granular material 16 is provided within the sealing portion 13. This makes it possible to reduce the amount of sealing portion 13 used, shorten the curing time of the sealing portion 13, and reduce the manufacturing cost of the sealing portion 13, assuming that the gap space between the middle frame 20 and the curved panel portion 1211 is fixed by utilizing the hole 15 and / or granular material 16 provided within the sealing portion 13.

[0063] Exemplary, in one embodiment of the present invention, as shown in Figure 16, the sealing portion 13 is provided with at least one hole 15. This reduces the amount of sealing portion 13 used, shortens the curing time of the sealing portion 13, and reduces the manufacturing cost of the sealing portion 13, while maintaining the gap space between the middle frame 20 and the curved panel portion 1211 by utilizing the hole 15 provided in the sealing portion 13. In this embodiment, the sealing portion 13 may be provided with one hole 15 or with multiple holes 15.

[0064] In another embodiment of the present invention, as shown in Figure 17, the sealing portion 13 is provided with at least one granular material 16. This reduces the amount of sealing portion 13 used, shortens the curing time of the sealing portion 13, and reduces the manufacturing cost of the sealing portion 13, assuming that the gap space between the middle frame 20 and the curved panel portion 1211 is fixed by utilizing the granular material 16 provided in the sealing portion 13. In this embodiment, the sealing portion 13 may be provided with one granular material 16 or with multiple granular materials 16.

[0065] In another embodiment of the present invention, as shown in Figure 18, the sealing portion 13 is provided with at least one hole 15 and at least one granular material 16. This reduces the amount of sealing portion 13 used, shortens the curing time of the sealing portion 13, and reduces the manufacturing cost of the sealing portion 13, while maintaining the gap space between the middle frame 20 and the curved panel portion 1211 by utilizing the hole 15 and granular material 16 provided in the sealing portion 13.

[0066] As an option, in one embodiment of the present invention, as shown in Figure 19, if a plurality of holes 15 are provided in the sealing portion 13, the density of holes 15 in the sealing portion 13 gradually decreases along the direction from the curved panel portion 1211 toward the middle frame 20. This reduces the amount of material used in the sealing portion 13 while improving the degree of bonding between the middle frame 20 and the sealing portion 13.

[0067] As shown in Figure 20, when multiple granular materials 16 are provided in the sealing portion 13, the density of the granular materials 16 in the sealing portion 13 gradually decreases along the direction from the curved panel portion 1211 toward the middle frame 20. This reduces the amount of material used in the sealing portion 13 while improving the degree of bonding between the middle frame 20 and the sealing portion 13.

[0068] In another embodiment of the present invention, as shown in Figure 21, when the sealing portion 13 is provided with a plurality of holes 15, the density of the holes 15 in the sealing portion 13 is uniformly distributed along the direction from the curved panel portion 1211 toward the middle frame 20. As a result, the uniform distribution of the holes 15 in the sealing portion 13 reduces the amount of material used in the sealing portion 13, while also making the performance distribution of each part of the sealing portion 13 more uniform.

[0069] As shown in Figure 22, when multiple granular materials 16 are provided in the sealing portion 13, the density of the granular materials 16 within the sealing portion 13 is uniformly distributed along the direction from the curved panel portion 1211 toward the middle frame 20. As a result, the granular materials 16 in the sealing portion 13 are uniformly distributed, reducing the amount of material used in the sealing portion 13, while also making the performance distribution of each part of the sealing portion 13 more uniform.

[0070] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 23, the display panel 121 further includes a first panel portion 1212 and a second panel portion 1213. The curved panel portion 1211 has a curvature direction, and both ends of the curved panel portion 1211 in the curvature direction are connected to the first panel portion 1212 and the second panel portion 1213. The first panel portion 1212 is closer to the cover plate 11 than the second panel portion 1213. Optionally, the first panel portion 1212, the curved panel portion 1211, and the second panel portion 1213 are integrally structured. In this embodiment, in the thickness direction Y of the cover plate 11, the support portion 122 is located between the first panel portion 1212 and the second panel portion 1213.

[0071] In one embodiment of the present invention, as shown in Figures 23 and 24, at least one of the filling portion 17 and the lining support portion 18 is provided inside the curved panel portion 1211. Here, if the filling portion 17 and the sealing portion 13 are made of the same material, when the filling portion 17 is provided inside the curved panel portion 1211, the filling portion 17 and the sealing portion 13 can be manufactured from the same material, thereby simplifying the manufacturing process of the display device. If the lining support portion 18 and the sealing portion 13 are made of different materials, when the lining support portion 18 is provided inside the curved panel portion 1211, the lining support portion 18 and the sealing portion 13 can be manufactured from corresponding materials according to different usage requirements.

[0072] Exemplary, in one embodiment of the present invention, as subsequently shown in Figures 23 and 24, when a filling portion 17 or lining support portion 18 is provided inside the curved panel portion 1211, the side of the filling portion 17 or lining support portion 18 closer to the middle frame 20 is joined to the curved panel portion 1211, and the side of the filling portion 17 or lining support portion 18 further away from the middle frame 20 is joined to one side of the support portion 122. This fixes the position of the inner surface of the curved panel portion 1211 and reduces the probability of the curved panel portion 1211 oscillating by completely filling the gap between the curved panel portion 1211 and the support portion 122.

[0073] In another embodiment of the present invention, as shown in Figures 25 and 26, when a filling portion 17 or a lining support portion 18 is provided inside the curved panel portion 1211, the side of the filling portion 17 or the lining support portion 18 closer to the middle frame 20 is joined to the inside of the curved panel portion 1211, and the side of the filling portion 17 or the lining support portion 18 further away from the middle frame 20 and one side of the support portion 122 have a second setting interval b, the second setting interval b being greater than zero.

[0074] As a result, the filling portion 17 or the lining support portion 18 does not come into contact with the support portion 122, and during the manufacturing process of the filling portion 17 or the lining support portion 18, it is prevented from penetrating into the composite layer 123 by capillary action, thereby preventing contamination and / or delamination of the composite layer 123.

[0075] Optionally, in one embodiment of the present invention, as shown in Figures 27 and 28, in the first direction X, the composite layer 123 has a length shorter than the support portion 122. That is, the distance between the end of the composite layer 123 facing the curved panel portion 1211 and the apex of the arc of the curved panel portion 1211 is greater than the distance between the end of the support portion 122 facing the curved panel portion 1211 and the apex of the arc of the curved panel portion 1211.

[0076] In this embodiment, when a filling portion 17 or an interior support portion 18 is provided inside the curved panel portion 1211, the side of the filling portion 17 or the interior support portion 18 closer to the middle frame 20 is joined to the curved panel portion 1211, and the side of the filling portion 17 or the interior support portion 18 further away from the middle frame 20 is joined to one side of the support portion 122, but has a first sub-setting interval c with respect to the side of the composite layer 123 closer to the middle frame 20.

[0077] This allows the position of the inner surface of the curved panel portion 1211 to be fixed using the filling portion 17 or the lining support portion 18, thereby reducing the probability of the curved panel portion 1211 oscillating, while preventing the filling portion 17 or the lining support portion 18 from contacting the composite layer 123, thus preventing them from penetrating the interior of the composite layer 123 by capillary action during the manufacturing process of the filling portion 17 or the lining support portion 18, and thus preventing internal contamination and / or delamination of the composite layer 123.

[0078] In yet another embodiment of the present invention, as shown in Figure 29, a filling portion 17 and an interior support portion 18 are provided inside the curved panel portion 1211, and the interior support portion 18 and the filling portion 17 are arranged sequentially along the direction from the inside of the curved panel portion 1211 toward the support portion 122. This allows the display device to select different materials depending on the usage requirements of different positions in the space between the curved panel portion 1211 and the support portion 122 in the first direction X. Optionally, in one embodiment of the present invention, the interior support portion 18 has a greater curing strength than the filling portion 17.

[0079] This reduces the likelihood of internal contamination and / or delamination of the composite layer 123 by capillary action during the manufacturing process of the lining support portion 18. In other embodiments of the present invention, as shown in Figure 30, the filling portion 17 and the lining support portion 18 are arranged in order along the direction from the inside of the curved panel portion 1211 toward the support portion 122, and optionally, in this embodiment, the curing strength of the filling portion 17 is greater than that of the lining support portion 18, reducing the likelihood of internal contamination and / or delamination of the composite layer 123 by capillary action during the manufacturing process of the filling portion 17.

[0080] Exemplary, in one embodiment of the present invention, as subsequently shown in Figure 29, when the length of the support portion 122 is greater than the length of the composite layer 123 in the first direction X, the boundary line between the filling portion 17 and the lining support portion 18 is flush with the end face of the support portion 122 on the side facing the curved panel portion 1211. This makes it easy to control the boundary line between the filling portion 17 and the lining support portion 18 when manufacturing the filling portion 17 and the lining support portion 18.

[0081] In yet another embodiment of the present application, as shown in Figure 31, a filling portion 17 and an interior support portion 18 are provided inside the curved panel portion 1211, and the filling portion 17 and the interior support portion 18 are arranged in order along the direction from the backlight side of the cover plate 11 toward the support base 21. In yet another embodiment of the present application, as shown in Figure 32, the interior support portion 18 and the filling portion 17 are arranged in order along the direction from the backlight side of the cover plate 11 toward the support base 21, so that the display device can select an appropriate material according to the usage requirements of different positions in the space between the curved panel portion 1211 and the support portion 122 in the first direction X.

[0082] As an option, in one embodiment of the present invention, the maximum lengths of the filling portion 17 and the lining support portion 18 are equal in the thickness direction Y of the cover plate 11. That is, the filling portion 17 occupies half of the housing space composed of the curved panel portion 1211, the support portion 122, and the composite layer 123, and the lining support portion 18 occupies half of the housing space composed of the curved panel portion 1211, the support portion 122, and the composite layer 123, so that the filling portion 17 and the lining support portion 18 are uniformly distributed in the housing space composed of the curved panel portion 1211, the support portion 122, and the composite layer 123.

[0083] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 32, the support portion 122 includes a first support portion 1221 and a second support portion 1222. The first support portion 1221 is located on the side of the first panel portion 1212 away from the cover plate 11, thereby fixing the shape of the first panel portion 1212 when the display panel 121 is a flexible display.

[0084] The second support portion 1222 is located on the side of the second panel portion 1213 facing the cover plate 11, thereby fixing the shape of the second panel portion 1213 when the display panel 121 is a flexible display. Exemplaryly, in this embodiment, the end of the first support portion 1221 closest to the curved panel portion 1211 is the first end, and the end of the second support portion 1222 closest to the curved panel portion 1211 is the second end. In the thickness direction Y of the display panel 121, the first end is flush with the second end, which facilitates the manufacturing of the support portion 122 and the composite layer 123.

[0085] In another embodiment of the present application, as shown in Figure 33, the end of the first support portion 1221 closest to the curved panel portion 1211 is the first end A, and the end of the second support portion 1222 closest to the curved panel portion 1211 is the second end B. By offsetting the first end A and the second end B in the thickness direction Y of the display panel 121, the relative position of the first end A and the second end B reduces the area of ​​the bezel region of the display device.

[0086] As an option, in one embodiment of the present invention, as shown in Figure 33, the curved panel portion 1211 is provided with an arc apex 12110, and the first end A of the first support portion 1221 is closer to the arc apex 12110 of the curved panel portion 1211 than the second end B of the second support portion 1222. In actual manufacturing, in the first direction X, the distance between the end of the cover plate 11 away from the curved panel portion 1211 and the curved panel portion 1211 is a fixed value.

[0087] In this embodiment, the first end A of the first support portion 1221 is closer to the arc apex 12110 of the curved panel portion 1211 than the second end B of the second support portion 1222. This causes the structure, including the second support portion 1222 and the composite layer 123, to move away from the curved panel portion 1211 of the support portion 122, thereby reducing the maximum distance of the curved panel portion 1211 in the first direction X. Furthermore, it reduces the length of the cover plate 11 in the first direction X, ultimately reducing the area of ​​the bezel region of the display device, assuming that the display area is fixed.

[0088] Exemplary, in one embodiment of the present invention, as shown in Figure 33, the curved panel portion 1211 includes a first bent plate portion 12111 connected to the first panel portion 1212 and a second bent plate portion 12112 connected to the second panel portion 1213. By setting the radii of curvature of the first bent plate portion 12111 and the second bent plate portion 12112 to be different from the radius of curvature of the second bent plate portion 12112, the area of ​​the bezel region of the display device can be reduced.

[0089] As an option, in one embodiment of the present invention, as shown in Figure 33, the radius of curvature of the first bent plate portion 12111 is smaller than the radius of curvature of the second bent plate portion 12112. Assuming that the display area of ​​the display panel 121 is fixed, reducing the radius of curvature of the first bent plate portion 12111 causes the structures such as the second support portion 1222 and the composite layer 123 to move away from the curved panel portion 1211 of the support portion 122 as a whole, reducing the maximum distance of the curved panel portion 1211 in the first direction X, further reducing the length of the cover plate 11 in the first direction X, and finally reducing the area of ​​the bezel region of the display device as assumed that the display area is fixed.

[0090] For example, in one embodiment of the present invention, the radius of curvature of the second bent plate portion 12112 is in the range of 0.15 mm to 0.3 mm. This prevents the second bent plate portion 12112 from breaking and the signal lines of the second bent plate portion 12112 from severing if the radius of curvature of the second bent plate portion 12112 is too small, and at the same time prevents the area of ​​the bezel region of the display device from increasing if the radius of curvature of the second bent plate portion 12112 is too large.

[0091] Optionally, in one embodiment of the present invention, the radius of curvature of the first bent plate portion 12111 is in the range of 0.05 mm to 0.2 mm. This ensures that the radius of curvature of the first bent plate portion 12111 is smaller than the radius of curvature of the second bent plate portion, while simultaneously preventing the first bent plate portion 12111 from breaking and the signal lines of the first bent plate portion 12111 from severing if the radius of curvature of the first bent plate portion 12111 is too small, and preventing an increase in the area of ​​the bezel region of the display device if the radius of curvature of the first bent plate portion 12111 is too large.

[0092] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 34, at least one first projection 132 is provided on the side of the sealing portion 13 away from the cover plate 11, and a first groove is provided on the side of the support base 21 closer to the cover plate 11. By positioning at least a portion of the first projection 132 within the first groove, the combination of the first projection 132 and the first groove enhances the fixed connection performance between the sealing portion 13 and the support base 21.

[0093] Optionally, as shown in Figure 34 in the cross-sectional view of the display device, the size of the first projection 132 in the first direction X gradually decreases in the direction away from the cover plate 11 of the sealing portion 13. Exemplarily, the first projection 132 has a first surface and a second surface facing each other in the first direction X, and the distance between the first surface and the second surface gradually decreases in the first direction X, making it easier to insert at least a portion of the first projection 132 into the first groove.

[0094] In one embodiment of the present invention, as shown in Figure 34, the angle between the first surface of the first projection 132 and the plane on which the cover plate 11 is located is acute, and the angle between the second surface of the first projection 132 and the plane on which the cover plate 11 is located is also acute. In another embodiment of the present invention, as shown in Figure 35, the angle between the first surface of the first projection 132 and the plane on which the cover plate 11 is located is right, and the angle between the second surface of the first projection 132 and the plane on which the cover plate 11 is located is acute.

[0095] In another embodiment of the present invention, as shown in Figure 36, the angle between the first surface of the first projection 132 and the plane on which the cover plate 11 is located is acute, and the angle between the second surface of the first projection 132 and the plane on which the cover plate 11 is located is right.

[0096] In the above embodiment, as shown in Figure 35, if the angle between the first surface of the first projection 132 and the plane on which the cover plate 11 is located is a right angle, the first surface of the first projection 132 may be located in the same vertical plane as the end face of the support base 21 on the side away from the middle frame 20.

[0097] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 37, the display device further comprises a connecting plate 40. The connecting plate 40 is located on the side of the second panel portion 1213 away from the cover plate 11 and supports the display assembly 10 in the thickness direction Y of the cover plate 11 from the side of the second panel portion 1213 away from the cover plate 11. Optionally, in this embodiment, a portion of the connecting plate 40 is also located within the sealing portion 13, thereby improving the fixed connection performance between the connecting plate 40 and the sealing portion 13, and simultaneously supporting the sealing portion 13 in the thickness direction Y of the cover plate 11 using the connecting plate 40, thereby reducing the load on the support base 21.

[0098] For example, in one embodiment of the present invention, the connecting plate 40 is a sheet metal part in order to improve the support strength of the connecting plate 40.

[0099] As an option, in one embodiment of the present invention, the display device further comprises an adhesive located between the connecting plate 40 and the second panel portion 1213 to achieve a fixed connection between the connecting plate 40 and the second panel portion 1213.

[0100] In one embodiment of the present invention, as shown in Figure 38, the connecting plate 40 includes a plate body 41 and at least one second projection 42 located on the surface of the plate body 41. Optionally, in one embodiment, the second projection 42 extends in a direction away from the cover plate 11, and the second projection 42 is directly fitted into the support base 21. This improves the fixed connection performance between the connecting plate 40 and the support base 21 by utilizing the second projection 42.

[0101] In another embodiment of the present application, the second projection 42 extends in a direction away from the cover plate 11, and the second projection 42 is indirectly fitted onto the support base 21. This improves the fixed connection performance between the second projection 42 and the support base 21 by using the second projection 42 to improve the fixed connection performance between the connecting plate 40 and the support base 21, through the connecting component between the second projection 42 and the support base 21. Optionally, in one embodiment of the present application, the second projection 42 is fitted onto the support base 21 via an adhesive layer. That is, an adhesive layer is provided between the second projection 42 and the support base 21, and the adhesive layer improves the fixing strength between the second projection 42 and the support base 21.

[0102] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 39, the second projection 42 and the sealing portion 13 overlap at least partially in the thickness direction Y of the cover plate 11, and at least a portion of the second projection 42 is located within the sealing portion 13. This allows the second projection 42 to be used to simultaneously improve the fixed connection performance between the connecting plate 40 and the sealing portion 13, and the fixed connection performance between the connecting plate 40 and the support base 21.

[0103] Optionally, in one embodiment of the present application, as shown in Figure 39, the second projection 42 extends through the portion of the sealing portion 13 located between the plate body 41 and the support base 21 into the support base 21. This simultaneously ensures that at least a portion of the second projection 42 is located within the sealing portion 13 and that the second projection 42 is fitted into the support base 21. In other embodiments of the present application, the second projection 42 may, through other means, simultaneously ensure that at least a portion of the second projection 42 is located within the sealing portion 13 and that the second projection 42 is fitted into the support base 21.

[0104] In another embodiment of the present invention, as shown in Figure 38, the second projection 42 and the sealing portion 13 do not overlap in the thickness direction Y of the cover plate 11, while the second projection 42 and the display module 12 overlap in the thickness direction Y of the cover plate 11, thereby improving the support strength of the connecting plate 40 for the display module 12.

[0105] As an option, in one embodiment of the present invention, the second projection 42 and the sealing portion 13 have a third set interval in the first direction X. The length range of the third set interval is 0.1 mm to 0.5 mm, which reduces the area of ​​the bezel region of the display device and makes it easier to achieve a narrow bezel for the display device.

[0106] Exemplary, in one embodiment of the present invention, as shown in Figure 40, the second projection 42 at least partially overlaps with at least two functional layers of the composite layer 123. As a result, the second projection 42 provides support to the composite layer 123, the support portion 122, and the display panel 121, improving the support strength of the connecting plate 40 to the display module 12. In other embodiments of the present invention, the second projection 42 may at least partially overlap with one functional layer in the composite layer 123, or it may not overlap with the composite layer 123 at all, and this can be selected as appropriate.

[0107] As an option, in one embodiment of the present invention, as shown in Figure 40, the support base 21 is provided with a first end 212 and a second end 211, the first end 212 of the support base 21 is located on the side closer to the middle frame 20, and the second end 211 of the support base 21 is located on the side further away from the middle frame 20. The distance f between the second projection 42 and the first end 212 of the support base 21 is greater than the distance e between the second projection 42 and the second end 211 of the support base 21.

[0108] As a result, the second projection 42 is located in a region of the plate body 41 close to the composite layer 123, and the connection end between the plate body 41 and the middle frame 20 and the second projection 42 are used to improve the stability of the connecting plate 40, while at the same time reducing the probability that both ends of the display panel 121 will lift up in the first direction X when the display panel 121 is pressed.

[0109] In some embodiments, the second end 211 of the support base 21 is the end of the support base 21 that is away from the middle frame 20.

[0110] As an example, in one embodiment of the present invention, the ratio of the distance f between the second projection 42 and the first end 212 to the distance e between the second projection 42 and the second end 211 is in the range of 5 to 8. This allows the second projection to be relatively close to the area of ​​the composite layer 123, improving the stability of the connecting plate 40 by utilizing the connection end between the plate body 41 and the middle frame 20 and the second projection 42, while simultaneously reducing the probability that both ends of the display panel 121 will lift up in the first direction X when the display panel 121 is pressed.

[0111] As an option, in one embodiment of the present invention, in the first direction X, the length of the support base 21 is 1 mm, the distance f between the second projection 42 and the first end 212 is in the range of 0.8 mm to 0.9 mm, and the distance e between the second projection 42 and the second end 211 is in the range of 0.1 mm to 0.2 mm.

[0112] In another embodiment of the present invention, as shown in Figure 41, the support base 21 is provided with a first end 212 and a second end 211, the first end 212 of the support base 21 is located on the side closer to the middle frame 20, and the second end 211 of the support base 21 is located on the side further away from the middle frame 20. The distance f between the second projection 42 and the first end 212 of the support base 21 is smaller than the distance e between the second projection 42 and the second end 211 of the support base 21.

[0113] As a result, the second projection 42 is located in a region of the plate body 41 that is close to the middle frame 20. In other embodiments of the present application, the distance f between the second projection 42 and the first end 212 of the support base 21 may be equal to the distance e between the second projection 42 and the second end 211 of the support base 21.

[0114] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 40, the curved panel portion 1211 is positioned between the middle frame 20 and the second projection 42 along the first direction X. As a result, the curved panel portion 1211 is positioned between the connection end of the plate body 41 and the middle frame 20 and the second projection 42, improving the stability of the curved panel portion 1211 in the thickness direction Y of the cover plate 11.

[0115] In yet another embodiment of the present invention, as shown in Figure 42, the connecting plate 40 includes a plate body 41 and at least one second projection 42 located on the surface of the plate body 41. The second projection 42 extends in a direction toward the cover plate 11, thereby utilizing the second projection 42 to improve the fixed connection performance between the connecting plate 40 and the sealing portion 13.

[0116] As an option, in one embodiment of the present invention, the structure of the display device can be simplified by directly fitting the second projection 42 into the sealing portion 13. In other embodiments of the present invention, the second projection 42 may be indirectly fitted into the sealing portion 13.

[0117] Exemplary, in one embodiment of the present invention, as shown in Figure 42, the support base 21 is provided with a first end 212 and a second end 211, the first end 212 of the support base 21 is located on the side closer to the middle frame 20, and the second end 211 of the support base 21 is located on the side further away from the middle frame 20. The distance h2 between the second projection 42 and the first end 212 of the support base 21 is smaller than the distance h1 between the second projection 42 and the second end 211 of the support base 21. This ensures that the second projection 42 is located in the area of ​​the plate body 41 closer to the middle frame 20, preventing damage to the curved panel portion 1211 when the second projection 42 is inserted into the sealing portion 13.

[0118] Exemplary, in one embodiment of the present invention, the ratio of the distance h1 between the second projection 42 and the second end 211 to the distance h2 between the second projection 42 and the first end 212 is in the range of 1 to 5. This ensures that the second projection 42 is located in an area of ​​the plate body 41 close to the middle frame 20, preventing damage to the curved panel portion 1211 when the second projection 42 is inserted into the sealing portion 13.

[0119] In yet another embodiment of the present invention, as shown in Figure 43, the connecting plate 40 includes a plate body 41 and at least one third projection 43 located on the plate body 41, and a groove is provided on the side of the support base 21 away from the middle frame 20. As a result, at least a portion of the third projection 43 is positioned in the groove provided on the side surface of the middle frame 20, allowing the third projection 43 on the connecting plate 40 to be inserted into the support base 21 from the side surface of the support base 21, thereby achieving a fixed connection between the connecting plate 40 and the support base 21.

[0120] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 44, the display panel 121 is provided with a sensor installation area 50. The sealing portion 13 surrounds the display panel 121 at least partially, and the sealing portion 13 is provided with at least one retractable portion 133 at a position corresponding to the sensor installation area 50. This prevents the jig of the sealing portion 13 from pressing against the sensor installation area 50 during the formation process of the sealing portion 13 and damaging the elements located in the sensor installation area 50.

[0121] In the above embodiment, the sealing portion 13 may completely enclose the display panel 121, as shown in Figure 44, or it may partially enclose the display panel 121, as shown in Figure 45.

[0122] Exemplary, in one embodiment of the present invention, devices such as an optical sensor and a camera are provided in the sensor installation area 50 of the display panel 121. Here, the optical sensor may include a visible light sensor, and may further include an infrared sensor or the like.

[0123] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 38, the composite layer 123 is located on the side of the support portion 122 away from the cover plate 11. Exemplarily, the support portion 122 includes a first support portion 1221 and a second support portion 1222, the first support portion 1221 is located on the side of the first panel portion 1212 away from the cover plate 11, the second support portion 1222 is located on the side of the second panel portion 1213 facing the cover plate 11, and the composite layer 123 is located between the first support portion 1221 and the second support portion 1222.

[0124] As an option, in one embodiment of the present invention, as shown in Figure 46, a first opening 61 is provided in at least a portion of the film layer of the display panel 121 and the support portion 122, and the first opening 61 is provided in the sensor installation area 50. This prevents the display panel 121 and the support portion 122 from obstructing the light ray collection direction of the sensor installation area 50, and avoids the display panel 121 and the support portion 122 from obstructing the light ray collection of the sensor installation area 50.

[0125] In another embodiment of the present invention, at least one film layer of the composite layer 123 overlaps with the sensor installation area 50 in the thickness direction Y of the cover plate 11. In this embodiment, as shown in Figure 47, a second opening 62 is provided in at least a portion of the film layer of the composite layer 123, and the second opening 62 is provided in the sensor installation area 50. This prevents the composite layer 123 from obstructing the collection of light rays in the sensor installation area 50.

[0126] In another embodiment of the present invention, as shown in Figure 47, a first aperture 61 is provided in at least a portion of the film layer of the display panel 121 and the support portion 122, and a second aperture 62 is provided in at least a portion of the film layer of the composite layer 123. By providing the first aperture 61 and the second aperture 62 in the sensor installation area 50, the display panel 121, the support portion 122, and the composite layer 123 are prevented from obstructing the collection of light rays in the sensor installation area 50.

[0127] As an option, in one embodiment of the present invention, the sensor installation area 50 is provided in the upper bezel area of ​​the display device so as to ensure that the sensor installation area 50 has a good field of view for collecting light rays.

[0128] In the above embodiment, as shown in Figure 47, at least a portion of the sealing portion 13 is provided on the side of the composite layer 123 away from the cover plate 11. In this embodiment, as shown in Figures 44 and 47, there is a fourth set interval h3 between the retracted portion 133 and at least one of the first opening 61 and the second opening 62. This ensures a gap between the retracted portion 133 and at least one of the first opening 61 and the second opening 62, reducing the possibility that the jig of the sealing portion 13 may press against the sensor installation area 50 due to process errors during the manufacturing of the sealing portion 13, thereby damaging the elements located in the sensor installation area 50.

[0129] Optionally, in one embodiment of the present invention, the range of the fourth setting interval h3 is 1.0 mm to 2.0 mm. This prevents damage to elements located in the sensor installation area 50 by ensuring that the fixture of the sealing portion 13 does not press against the sensor installation area 50 within the process tolerance range if the fourth setting interval h3 is too small. At the same time, it prevents the area of ​​the upper bezel region of the display panel 121 from becoming too large and affecting the user experience if the fourth setting interval h3 is too large.

[0130] Exemplary, in one embodiment of the present invention, the range of the fourth setting interval h3 is 1.3 mm to 1.5 mm. This prevents the fixture of the sealing portion 13 from pressing against the sensor installation area 50 and damaging the elements located in the sensor installation area 50, while reducing the area of ​​the upper bezel region of the display panel 121.

[0131] Based on any of the above embodiments, in one embodiment of the present application, the diameter of the first aperture 61 is smaller than the diameter of the second aperture 62, thereby ensuring that all light rays passing through the first aperture 61 can also pass through the second aperture 62, while reducing the difficulty of alignment when aligning the first aperture 61 and the second aperture 62.

[0132] Based on any of the above embodiments, in one embodiment of the present application, the shape of the retractable portion 133 is at least one of a rectangle, a semicircle, or an arc. This allows the retractable portion 133 to avoid the sensor installation area 50, while the regular shape of the retractable portion 133 reduces the process difficulty of the retractable portion 133. In other embodiments of the present application, the shape of the retractable portion 133 may be any other shape, as long as the retractable portion 133 avoids the sensor installation area 50.

[0133] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 43, the middle frame 20 includes a side frame 24 and a bottom frame 23, the side frame 24 is located on the side of the sealing portion 13 away from the curved panel portion 1211, and the bottom frame 23 is located on the side of the support base 21 away from the cover plate 11. In this embodiment, at least a portion of the support base 21 is located on the side of the side frame 24 closer to the display panel 121.

[0134] Optionally, in one embodiment of the present invention, as shown in Figure 48, the display panel 121 includes a display area 1214 and a bezel area 1215, and the bezel area 1215 includes a side bezel area 1216 and a stepped area 1217. The curved panel portion 1211 is provided in the stepped area 1217, and the side bezel area 1216 is provided with at least one resin injection area 71 and a corresponding resin discharge area 72. Exemplarily, in one embodiment of the present invention, the side bezel area 1216 is provided with four resin injection areas 71 and corresponding resin discharge areas 72.

[0135] In one embodiment of the present invention, as shown in Figure 49, which is a cross-sectional view along M1-M2 in Figure 47, the support base 21 is provided in the resin injection area 71 or the resin discharge area 72. This provides support for the display assembly 10 when it is overlapped and connected to the middle frame 20, while reducing the volume of the support base 21.

[0136] Exemplary, in one embodiment of the present application, as shown in Figures 48 to 51, where Figure 49 is a cross-sectional view along M1-M2 in Figure 48, Figure 50 is a cross-sectional view along M3-M4 in Figure 48, and Figure 51 is a cross-sectional view along M5-M6 in Figure 48. The sealing portion 13 includes a first sealing portion 134 and a second sealing portion 135, the first sealing portion 134 is provided in at least one of the resin injection region 71 and the resin discharge region 72, and the second sealing portion 135 is provided in the stepped region 1217 and other regions of the side bezel region 1216.

[0137] In other words, in this embodiment, the sealing portion 13 is divided into two parts: one part is the portion of the sealing portion 13 located in the resin injection region 71 and / or the resin discharge region 72, i.e., the first sealing portion 134; and the other part is the portion of the sealing portion 13 other than the portion located in the resin injection region 71 and / or the resin discharge region 72, i.e., the second sealing portion 135.

[0138] In one embodiment of the present invention, as shown in Figure 49, an injection-molded rib 136 is provided on the side of the first sealing portion 134 away from the cover plate 11, and a second groove is provided in the support base 21. By positioning the injection-molded rib 136 within the second groove, when the display assembly 10 is overlap-connected to the middle frame 20, the relative position between the display assembly 10 and the middle frame 20 is restricted using the injection-molded rib 136, eliminating the need to add other restricting structures and simplifying the structure of the display device.

[0139] Furthermore, in the above embodiment, the injection-molded rib 136 on the first sealing portion 134 is located in the second groove of the support base 21, and the combination of the injection-molded rib 136 and the second groove can also improve the stability between the sealing portion 13 and the support base 21.

[0140] In one embodiment of the present invention, when the first projection on the sealing portion 13 extends in a direction away from the cover plate 11, the second projection can be reused as the first projection. This simplifies the structure of the display device.

[0141] Exemplary, in one embodiment of the present invention, as shown in Figure 49, the width of the cross-section of the injection-molded rib 136 widens towards the front and then narrows towards the back along the thickness direction Y away from the display panel 121 of the cover plate 11. This makes it easier to insert the injection-molded rib 136 into the second groove of the support base 21 and reduces the difficulty of inserting the injection-molded rib 136.

[0142] As shown in Figures 50 and 51, in one embodiment of the present invention, the injection-molded rib 136 is not provided on the side of the second sealing portion 135 away from the cover plate 11, and the support base 21 is not provided on the side of the second sealing portion 135 away from the cover plate 11. This reduces the volume occupied by the sealing portion 13 and the support base 21 inside the display device, and secures more space for arranging other structures inside the display device.

[0143] In other embodiments of the present invention, a support base 21 may be provided on the side of the second sealing portion 135 away from the cover plate 11, and correspondingly, an injection-molded rib 136 is provided on the side of the second sealing portion 135 away from the cover plate 11. This improves the stability between the sealing portion 13 and the support base 21.

[0144] In other embodiments of the present invention, as shown in Figure 52, a support base 21 may be provided over the entire side of the sealing portion 13 away from the display panel 121. This allows the support base 21 to support the sealing portion 13 and the display assembly 10, while the support base 21 functions as a shielding plate on the non-display side of the display assembly 10, thereby improving the signal interference immunity of the display device.

[0145] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 49, there is a fifth setting interval h4 between the side of the support base 21 away from the cover plate 11 and the bottom frame 23. This allows the support base 21 to be provided on the display device to support the sealing portion 13 and the display module 12, while reducing the thickness of the support base 21 and expanding the internal design space of the display device.

[0146] As an option, in one embodiment of the present invention, the range of the fifth setting interval h4 is 2 mm to 10 mm. If the fifth setting interval h4 is too small, it avoids the inability to fully utilize the space between the support base 21 and the bottom frame 23. At the same time, if the fifth setting interval h4 is too large, it avoids the thickness of the display device increasing due to the setting of the fifth setting interval h4.

[0147] As shown in Figure 53, in one embodiment of the present invention, the display device further includes at least one of a battery and a main board 60. For example, the main board provides drive signals and control signals to the display device and ensures the normal operation of the display device. Optionally, in one embodiment of the present invention, at least a portion of at least one of the battery and the main board 60 is located between the support base 21 and the bottom frame 23 to make full use of the space between the support base 21 and the bottom frame 23.

[0148] In another embodiment of the present invention, as shown in Figure 54, the side of the support base 21 away from the cover plate 11 contacts the bottom frame 23, thereby increasing the fixing strength between the support base 21 and the middle frame 20, improving the stability of the support base 21, and further improving the support stability of the support base 21 with respect to the sealing portion 13 and the display module 12.

[0149] As described above, in the display device according to the embodiment of the present invention, the support base 21 and the display module 12 have a first overlapping region 30 in the thickness direction of the cover plate 11. As a result, the support base 21 and the display module 12 partially overlap, reducing the distance D2 between the end of the display module 12 facing the middle frame 20 and the surface of the middle frame 20 facing the display module 12 in a direction parallel to the plane on which the cover plate 11 is located, and further reducing the distance D3 between the end of the display module 12 facing the middle frame 20 and the surface of the middle frame 20 away from the display module 12. This reduces the area of ​​the bezel region of the display device in a direction parallel to the plane on which the cover plate 11 is located, adapting to the trend of narrow bezels.

Accordingly, features defined in “first,” “second,” “third,” and “fourth” mean that they may explicitly or implicitly include one or more such features.

[0151] In the description of embodiments of this application, the terms “composes,” “includes,” or any other variation thereof mean non-exclusive inclusion, and a process, method, article, or apparatus comprising a set of elements means that it includes not only those elements but also other elements not enumerated, or elements specific to such process, method, article, or apparatus. Unless otherwise specified, an element identified in the expression “composes one…” does not preclude the presence of other identical elements in a process, method, article, or apparatus comprising that element.
