[0064] The following describes the embodiments of the present application in conjunction with the accompanying drawings, which are part of the embodiments of the present application. Based on the embodiments of the present application, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of this application.

[0065] Many details are set forth in the following description to facilitate understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the present application.

[0066] A display device typically includes a midframe and a display assembly. 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 actual use, the display assembly is assembled onto the midframe via the cover plate, forming a display device.

[0067] As shown in Figure 1, perpendicular to the plane of the display device, the middle frame comprises a first portion 01 and a second portion 02. The inner diameter of the first portion 01 is larger than that of the second portion 02, forming a stepped surface at the junction of the first and second portions 01 and 02. The cover plate 03 is overlapped on the stepped surface with caulking adhesive 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 facing away from the display assembly is large, resulting in a larger border area in the display device shown in Figure 1. This, in turn, results in a larger black border corresponding to the border area in the display device shown in Figure 1, affecting the user experience.

[0068] An embodiment of the present application provides a display device, as shown in FIG2 , comprising:

[0069] The display assembly 10 includes a cover plate 11, a display module 12, and an encapsulation 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 encapsulation portion 13 is located on the backlight side of the cover plate 11. The encapsulation portion 13 at least partially surrounds the display module 12.

[0070] The middle frame 20 is provided with a support platform 21 at least partially in the circumferential direction. The support platform 21 is located on the side of the display module 12 away from the cover plate 11. The support platform 21 and the display module 12 have a first overlapping area 30 in the thickness direction Y of the cover plate 11.

[0071] Optionally, in one embodiment of the present application, the cover plate 11 is a glass cover plate, and the encapsulation portion 13 is a solid glue portion, that is, formed by curing glue.

[0072] In this embodiment, the encapsulation portion 13 may be partially or entirely located on the backlight side of the cover plate 11; the encapsulation portion 13 may partially or entirely surround the display module 12. The configuration of the encapsulation portion 13 in this application may vary depending on the circumstances.

[0073] In the display device provided in the embodiment of the present application, there is a first overlapping area 30 between the support platform 21 and the display module 12 in the thickness direction Y of the cover plate 11, so that the support platform 21 and the display module 12 partially overlap, thereby reducing the distance D2 between the end of the display module 12 facing the middle frame 20 and the side surface of the middle frame 20 facing the display module 12 in a plane parallel to the cover plate 11, thereby reducing the distance D3 between the end of the display module 12 facing the middle frame 20 and the side surface of the middle frame 20 away from the display module 12, so as to reduce the area of ​​the border area of ​​the display device in the plane parallel to the cover plate 11, which is suitable for the development trend of narrow borders.

[0074] Optionally, in one embodiment of the present application, in the first direction X, the ratio of the length of the first overlapping area 30 to the length of the support platform 21 is in the range of 0.1 to 0.4, so as to avoid the gap between the middle frame 20 and the display module 12 being too small, and the shaking of the middle frame 20 causing damage to the display module 12, and at the same time avoid the gap between the middle frame 20 and the display module 12 being too large, resulting in a larger area of ​​the border area of ​​the display device, which is not conducive to achieving a narrow border.

[0075] For example, in one embodiment of the present application, in the first direction X, the ratio of the length of the first overlapping area 30 to the length of the support platform 21 is in the range of 0.15 to 0.3, so as to take into account that the shaking of the middle frame 20 will not cause damage to the display module 12 and that the display device has a narrow border, thereby achieving a better balance between the shaking of the middle frame 20 not causing damage to the display module 12 and the display device having a narrow border.

[0076] Optionally, in one embodiment of the present application, in the first direction X, the length of the first overlapping region 30 is not less than 0.5 millimeters (mm), so that the support platform 21 has better supporting strength for the display module 12 .

[0077] For example, in one embodiment of the present application, in the first direction X, the length of the support platform 21 is not less than 0.8 mm, so that the support platform 21 has a good supporting strength for the display module 12 .

[0078] For example, in one embodiment of the present application, as shown in FIG3 , the display module 12 includes a stacked display panel 121, a support portion 122, and a composite layer 123, wherein the composite layer 123 includes a plurality of functional layers, and the display panel 121 is provided with a curved panel portion 1211 on one side of a first direction X, wherein the first direction X is parallel to the plane where the cover plate 11 is located and perpendicular to the thickness direction Y of the cover plate 11.

[0079] In one embodiment of the present application, as shown in FIG4 , the support platform 21 and the curved panel portion 1211 of the display panel 121 in the display module 12 have an overlapping region, but do not overlap with the composite layer 123 and the support portion 122. This reduces the extension length of the support platform 21 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 platform 21 and the curved panel portion 1211 is the first overlapping region 30.

[0080] In another embodiment of the present application, as shown in Figure 3, the support platform 21 not only has an overlapping area with the curved panel portion 1211 of the display panel 121 in the display module 12, but also has an overlapping area with the composite layer 123 and the support portion 122, so as to increase the extension length of the support platform 21 toward the backlight side of the display module 12, thereby reducing the distance D2 between the end of the display module 12 facing the middle frame 20 and the side surface of the middle frame 20 facing the display module 12 in a plane parallel to the cover plate 11, and further reducing the distance D3 between the end of the display module 12 facing the middle frame 20 and the side surface of the middle frame 20 away from the display module 12, so as to reduce the area of ​​the border region of the display device in a plane parallel to the cover plate 11, thereby realizing a narrow border. In this embodiment, the overlapping area between the support platform 21 and the curved panel portion 1211 , and the overlapping area between the support platform 21 and at least one of the composite layer 123 and the support portion 122 together constitute the first overlapping area 30 .

[0081] Optionally, in one embodiment of the present application, as shown in Figures 3 and 5, in the first direction X, the length of the composite layer 123 is less than the length of the support portion 122. Exemplarily, in one implementation of this embodiment, a second overlapping region 31 exists between the support platform 21 and the composite layer 123. This reduces the border area of ​​the display device and achieves a narrow border. Furthermore, in the thickness direction Y of the cover plate 11, the support platform 21 provides a certain degree of support for the composite layer 123, thereby improving the stability of the display module 12 in the thickness direction Y of the cover plate 11.

[0082] In the above embodiment, among the multiple functional layers included in the composite layer 123, the sizes of different functional layers in the first direction may be the same, as shown in FIG3 , or may be different, as shown in FIG5 . Optionally, in one embodiment of the present application, the support platform 21 and the composite layer 123 have a second overlapping region 31 in the thickness direction Y of the cover plate 11. The second overlapping region 31 includes an overlapping region 311 between the support platform 21 and at least one functional layer of the composite layer 123 in the thickness direction Y of the cover plate 11, thereby achieving overlap between the support platform 21 and the composite layer 123.

[0083] Exemplarily, in one embodiment of the present application, the functional layer in the composite layer 123 includes a first functional layer 1231. In the first direction X, the first functional layer 1231 is the functional layer with the largest length in the composite layer 123, that is, the distance between the first functional layer 1231 and the arc top of the curved panel portion 1211 is smaller than the distance between other functional layers in the composite layer 123 and the arc top of the curved panel portion 1211.

[0084] In one embodiment of the present application, as shown in FIG6 , the support platform 21 has an overlapping region 311 only with the first functional layer 1231 in the composite layer 123, so as to balance the support strength of the support platform 21 for the display module 12 and the area occupied by the support platform 21 within the display device. In other embodiments of the present application, as shown in FIG5 , the support platform 21 has an overlapping region 311 not only with the first functional layer 1231 in the composite layer 123, but also with other functional layers in the composite layer 123, so as to enhance the support strength of the support platform 21 for the display module 12 and improve the stability of the display module 12 in the thickness direction Y of the cover plate 11.

[0085] Optionally, in one embodiment of the present application, as shown in Figure 5, the support platform 21 and at least two functional layers in the composite layer 123 are at least partially overlapped in the thickness direction Y of the cover plate 11, so as to increase the number of functional layers in the composite layer 123 that overlap with the support platform 21, thereby improving the support strength of the support platform 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.

[0086] For example, in one embodiment of the present application, in the first direction X, the numerical range of the second overlapping area 31 is 0.2 to 0.4 mm, so that the support platform 21 has a better supporting 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.

[0087] On the basis of any of the above embodiments, in one embodiment of the present application, as shown in Figure 6, the support platform 21 is provided with 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 platform 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 platform 21 on the plane where the cover plate 11 is located, so as to maximize the supporting effect of the support platform 21 on the curved panel portion 1211 on the basis of reducing the area of ​​the frame area of ​​the display device and realizing a narrow frame, thereby improving the stability of the curved panel portion 1211 in the thickness direction Y of the cover plate 11.

[0088] For example, in one embodiment of the present application, as shown in FIG6 , in the first direction X, between the end of the curved panel portion 1211 away from the middle frame 20 and the middle frame 20, the following is included: in the first direction X, the end 211 of the support platform 21 away from the middle frame 20 is located on one side of the end of the curved panel portion 1211 away from the middle frame 20, so as to ensure the support effect of the support platform 21 on the curved panel portion 1211. In another embodiment of the present application, as shown in FIG4 , in the first direction X, between the end of the curved panel portion 1211 away from the middle frame 20 and the middle frame 20, the following is included: in the thickness direction Y of the cover plate 11, the end 211 of the support platform 21 away from the middle frame 20 is flush with the end of the curved panel portion 1211 away from the middle frame 20, so as to reduce the length of the support platform 21 in the first direction X while ensuring the support effect of the support platform 21 on the curved panel portion 1211.

[0089] In one embodiment of the present application, as shown in FIG7 , the curved panel portion 1211 is provided with a curved top portion 12110, and a distance D4 between the curved top portion 12110 and the side of the middle frame 20 close to the curved panel portion 1211 is smaller than a distance D5 between the curved top portion 12110 and an end portion 211 of the support platform 21 away from the middle frame 20, thereby improving the support strength of the support platform 21 on the display module 12. In other embodiments of the present application, as shown in FIG8 , the curved panel portion 1211 is provided with a curved top portion 12110, and a distance D4 between the curved top portion 12110 and the side of the middle frame 20 close to the curved panel portion 1211 may also be larger than a distance D5 between the curved top portion 12110 and an end portion 211 of the support platform 21 away from the middle frame 20, thereby reducing the length of the support platform 21 in the first direction X, thereby reducing the space required by the support platform 21 to occupy within the display device.

[0090] 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, a copper foil, foam, and a graphite layer. The material of the composite layer 123 in the present application can be determined based on the use requirements of the composite layer 123 in the display device.

[0091] For example, in one embodiment of the present application, as shown in Figures 9 and 10, Figure 10 is a schematic diagram of the display component 10 in Figure 9 when it is in a flattened state. In this embodiment, the composite layer 123 includes: copper foil 1232, foam 1233, first graphite 1234 and double-sided tape 1235 stacked in the thickness direction Y of the cover plate 11, wherein the copper foil 1232 is used to achieve strength protection, the foam 1233 is used to achieve a buffering effect, the first graphite 1234 is used to achieve heat dissipation, and the double-sided tape 1235 is used to achieve bonding between the first graphite 1234 and the support portion 122.

[0092] For example, in one embodiment of the present application, 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 foam 1233 is 0.1 mm, the thickness of the graphite 1234 is 0.02 mm, and the thickness of the double-sided tape 1235 is 0.03 mm; when the display component 10 is in a flattened state, the width W of the curved panel portion 1211 in the first direction X is 1 mm.

[0093] In another embodiment of the present application, as shown in Figure 11, the composite layer 123 includes: a stainless steel plate 1236, a second graphite 1237 and a film 1238 stacked in the thickness direction Y of the cover plate 11, wherein the stainless steel plate 1236 is used to achieve strength protection, the second graphite 1237 is used to achieve heat dissipation, and the film 1238 is used to absorb a small amount of electromagnetic waves emitted by the display panel 121 to reduce the interference of the electromagnetic waves emitted by the display panel 121 on the radio frequency signal of the display device.

[0094] On the basis of any of the above embodiments, in one embodiment of the present application, as shown in Figures 9 and 11, the display component 10 further includes: a polarizer 124 located between the display panel 121 and the cover plate 11 to modulate the light from the external environment directed toward the display device to reduce interference from ambient light.

[0095] Based on any of the above embodiments, in one embodiment of the present application, the curved panel portion 1211 has an arc top portion 12110, and the arc top portion 12110 and the middle frame 20 have a first set spacing in the first direction X, referring to the distance D4 shown in Figure 8. The first set spacing is between 0.3mm and 0.6mm, that is, the value of D4 is between 0.3mm and 0.6mm, so as to prevent the middle frame 20 from vibrating in the first direction X when a force is applied, thereby preventing damage to the arc top portion 12110, and thus enabling the display device to have a narrow bezel.

[0096] On the basis of any of the above embodiments, in one embodiment of the present application, as shown in Figure 8, the side of the encapsulation portion 13 away from the curved panel portion 1211 is fitted with the side of the middle frame 20 close to the curved panel portion 1211, so that in the first direction X, the position of the encapsulation portion 13 remains fixed, reducing the probability of the encapsulation portion 13 shaking, thereby reducing the probability of damage to the arc top portion 12110 of the curved panel portion 1211 due to the shaking of the encapsulation portion 13.

[0097] Illustratively, in one embodiment of the present application, the encapsulation portion 13 is a glue portion, which is formed by curing glue, so that the encapsulation portion 13 has a certain flexibility, and thus the display device can use the encapsulation portion 13 to buffer the impact force on the arc top portion 12110 of the curved panel portion 1211 when the middle frame 20 is hit, thereby reducing the probability of the arc top portion 12110 of the curved panel portion 1211 being damaged.

[0098] Optionally, in one embodiment of the present application, the encapsulation portion 13 is made by a low-pressure injection molding (LIPO) process, so that the shape of the encapsulation portion 13 can be set to better fit the surface of the middle frame 20 facing the curved panel portion 1211.

[0099] As shown in Figure 12, in one embodiment of the present application, at least one reinforcing portion 22 is provided on the side of the middle frame 20 close to the curved panel portion 1211, so as to utilize the reinforcing portion 22 to improve the fit between the side of the middle frame 20 close to the curved panel portion 1211 and the side of the encapsulation portion 13 away from the curved panel portion 1211, thereby enhancing the stability of the relative position between the middle frame 20 and the encapsulation portion 13.

[0100] For example, in one embodiment of the present application, as shown in FIG12 , the reinforcing portion 22 is a protrusion, and accordingly, a groove is provided on the side of the encapsulation portion 13 away from the curved panel portion 1211, thereby improving the degree of fit between the side of the middle frame 20 close to the curved panel portion 1211 and the side of the encapsulation portion 13 away from the curved panel portion 1211 through the cooperation of the protrusion and the groove; in another embodiment of the present application, as shown in FIG13 , the reinforcing portion 22 is a groove, and accordingly, a protrusion is provided on the side of the encapsulation portion 13 away from the curved panel portion 1211, thereby improving the degree of fit between the side of the middle frame 20 close to the curved panel portion 1211 and the side of the encapsulation portion 13 away from the curved panel portion 1211 through the cooperation of the protrusion and the groove.

[0101] In some embodiments, a reinforcing portion 22 may be provided on the side of the middle frame 20 close to the curved panel portion 1211, or multiple reinforcing portions 22 may be provided, as long as the side of the encapsulation portion 13 away from the curved panel portion 1211 has the same number of adapting structures as the reinforcing portions 22.

[0102] Optionally, based on any of the above embodiments, in an embodiment of the present application, the reinforcing portion 22 is formed by curing glue, so that the reinforcing portion 22 has a certain flexibility, and thereby the reinforcing portion 22 reduces the interaction force between the middle frame 20 and the encapsulating portion 13 on the basis of enhancing the fit between the middle frame 20 and the encapsulating portion 13.

[0103] Optionally, in one embodiment of the present application, the reinforcing portion 22 is made by a low-pressure injection molding (LIPO) process, so that the shape of the reinforcing portion 22 can be set to better fit the surface of the middle frame 20 facing the curved panel portion 1211 and the surface of the encapsulation portion 13 away from the curved panel portion 1211.

[0104] For example, in one embodiment of the present application, the glue material of the reinforcement portion 22 may be epoxy resin glue, or may be acrylic or polyurethane.

[0105] In the above embodiment, the reinforcing portion 22 circumferentially surrounds part of the side surface of the display module 12. For example, the reinforcing portion 22 circumferentially surrounds one side surface of the display module 12 or two adjacent side surfaces of the display module 12, as long as it does not affect the assembly of the cover plate 11 and the middle frame 20.

[0106] In another embodiment of the present application, as shown in Figure 14, an inclined surface 131 is provided on the side of the encapsulation portion 13 away from the curved panel portion 1211, and a first angle α is provided between the inclined surface 131 and the side of the middle frame 20 close to the curved panel portion 1211, so as to utilize the contact point between the inclined surface 131 and the middle frame 20 to locate the assembly position of the middle frame 20 and the display component 10, thereby improving the positioning accuracy of the middle frame 20 and the display component 10 during assembly.

[0107] In one embodiment of the present application, as shown in FIG15 , a filling portion 14 is provided between the middle frame 20 and the inclined surface 131 of the encapsulation portion 13, so as to utilize the filling portion 14 to fill the gap between the encapsulation portion 13 and the middle frame 20, thereby reducing the probability of the encapsulation portion 13 shaking, thereby reducing the probability of the encapsulation portion 13 peeling off.

[0108] Optionally, in one embodiment of the present application, a first angle α between the inclined surface 131 and the side of the middle frame 20 proximate to the curved panel portion 1211 is in a range of 5° to 15°. This prevents the first angle α from being too small, making it difficult to use the inclination point of the inclined surface 131 for positioning, and prevents the first angle α from being too large, which could affect the protective strength of the encapsulating portion 13 on the side of the curved panel portion 1211 facing the middle frame 20. The unit of measurement for angles is degrees, represented by the symbol °.

[0109] In actual application, the side of the encapsulation portion 13 away from the middle frame 20 is also provided with an inclined surface, and the inclination angle of the inclined surface of the side of the encapsulation portion 13 away from the middle frame 20 is different from the inclination angle of the inclined surface of the side of the encapsulation portion 13 away from the curved panel portion 1211.

[0110] Optionally, in one embodiment of the present application, an angle between the inclined surface of the side of the encapsulation portion 13 away from the middle frame 20 and the middle frame 20 is 15°.

[0111] On the basis of any of the above embodiments, in one embodiment of the present application, as shown in Figures 16 to 18, at least one of the following is provided in the encapsulation portion 13: at least one hole 15 and at least one particle 16, so as to utilize the holes 15 and / or particles 16 provided in the encapsulation portion 13 to reduce the usage of the encapsulation portion 13 under the premise that the gap space between the middle frame 20 and the curved panel portion 1211 is fixed, thereby reducing the curing time of the encapsulation portion 13 and reducing the production cost of the encapsulation portion 13.

[0112] For example, in one embodiment of the present application, as further shown in FIG16 , the encapsulating portion 13 has at least one hole 15. By utilizing the hole 15 provided in the encapsulating portion 13, the amount of the encapsulating portion 13 used is reduced while maintaining the gap between the middle frame 20 and the curved panel portion 1211. This reduces the curing time of the encapsulating portion 13 and reduces the manufacturing cost of the encapsulating portion 13. In this embodiment, the encapsulating portion 13 may have one hole 15 or multiple holes 15.

[0113] In another embodiment of the present application, as shown in FIG17 , the encapsulating portion 13 includes at least one particle 16. The particles 16 disposed within the encapsulating portion 13 can be utilized to reduce the amount of the encapsulating portion 13 used, while maintaining a fixed gap between the middle frame 20 and the curved panel portion 1211. This reduces the curing time of the encapsulating portion 13 and reduces the manufacturing cost of the encapsulating portion 13. In this embodiment, the encapsulating portion 13 can include one particle 16 or multiple particles 16.

[0114] In another embodiment of the present application, as shown in Figure 18, at least one hole 15 and at least one particle 16 are provided in the encapsulation portion 13, so as to utilize the holes 15 and particles 16 provided in the encapsulation portion 13 to reduce the usage of the encapsulation portion 13 under the premise that the gap space between the middle frame 20 and the curved panel portion 1211 is fixed, thereby reducing the curing time of the encapsulation portion 13 and reducing the production cost of the encapsulation portion 13.

[0115] Optionally, in one embodiment of the present application, as shown in FIG19 , when a plurality of holes 15 are provided in the encapsulation portion 13, the density of the holes 15 in the encapsulation portion 13 gradually decreases along the direction from the curved panel portion 1211 toward the middle frame 20, thereby improving the fit between the middle frame 20 and the encapsulation portion 13 while reducing the amount of material used in the encapsulation portion 13. As shown in FIG20 , when a plurality of particles 16 are provided in the encapsulation portion 13, the density of the particles 16 in the encapsulation portion 13 gradually decreases along the direction from the curved panel portion 1211 toward the middle frame 20, thereby improving the fit between the middle frame 20 and the encapsulation portion 13 while reducing the amount of material used in the encapsulation portion 13.

[0116] In another embodiment of the present application, as shown in FIG21 , when a plurality of holes 15 are provided in the encapsulation portion 13, the density of the holes 15 in the encapsulation portion 13 is uniformly distributed along the direction from the curved panel portion 1211 toward the middle frame 20, so that the holes 15 in the encapsulation portion 13 are evenly distributed throughout the encapsulation portion 13, thereby reducing the amount of material used in the encapsulation portion 13 and achieving a relatively uniform performance distribution throughout the encapsulation portion 13. As shown in FIG22 , when a plurality of particles 16 are provided in the encapsulation portion 13, the density of the particles 16 in the encapsulation portion 13 is uniformly distributed along the direction from the curved panel portion 1211 toward the middle frame 20, thereby achieving a relatively uniform performance distribution throughout the encapsulation portion 13, thereby reducing the amount of material used in the encapsulation portion 13 and achieving a relatively uniform performance distribution throughout the encapsulation portion 13.

[0117] Based on any of the above embodiments, in one embodiment of the present application, as shown in FIG23 , the display panel 121 further includes: a first panel portion 1212 and a second panel portion 1213. The curved panel portion 1211 has a curved direction, and the curved panel portion 1211 is connected to the first panel portion 1212 and the second panel portion 1213 at both ends of the curved direction. 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, the support portion 122 is located between the first panel portion 1212 and the second panel portion 1213 in the thickness direction Y of the cover plate 11.

[0118] In one embodiment of the present application, as shown in Figures 23 and 24, at least one of a filling portion 17 and an inner supporting portion 18 is provided on the inner side of the curved panel portion 1211; wherein the filling portion 17 and the encapsulating portion 13 are made of the same material. Therefore, when the filling portion 17 is provided on the inner side of the curved panel portion 1211, the filling portion 17 and the encapsulating portion 13 can be made of the same material, thereby simplifying the manufacturing process of the display device. The inner supporting portion 18 and the encapsulating portion 13 are made of different materials. Therefore, when the inner supporting portion 18 is provided on the inner side of the curved panel portion 1211, the inner supporting portion 18 and the encapsulating portion 13 can be made of different materials according to different usage requirements.

[0119] For example, in one embodiment of the present application, as shown in Figures 23 and 24, when a filling portion 17 or an inner supporting portion 18 is provided on the inner side of the curved panel portion 1211, the side of the filling portion 17 or the inner supporting portion 18 close to the middle frame 20 is in contact with the curved panel portion 1211, and the side of the filling portion 17 or the inner supporting portion 18 away from the middle frame 20 is in contact with the side of the supporting portion 122, so that the filling portion 17 or the inner supporting portion 18 completely fills the gap between the curved panel portion 1211 and the supporting portion 122, so as to fix the position of the inner side surface of the curved panel portion 1211 and reduce the probability of the curved panel portion 1211 shaking.

[0120] In another embodiment of the present application, as shown in Figures 25 and 26, when a filling portion 17 or an inner supporting portion 18 is provided on the inner side of the curved panel portion 1211, the side of the filling portion 17 or the inner supporting portion 18 close to the middle frame 20 is in contact with the inner side of the curved panel portion 1211, and the side of the filling portion 17 or the inner supporting portion 18 away from the middle frame 20 is provided with a second set spacing b from the side of the support portion 122. The second set spacing b is greater than zero, so that the filling portion 17 or the inner supporting portion 18 does not contact the support portion 122, thereby preventing the filling portion 17 or the inner supporting portion 18 from entering the interior of the composite layer 123 due to the capillary effect during the manufacturing process, causing the interior of the composite layer 123 to be contaminated and / or peeling off.

[0121] Optionally, in one embodiment of the present application, as shown in Figures 27 and 28, in the first direction X, the length of the composite layer 123 is less than the length of the support portion 122, that is, the distance between the end of the composite layer 123 facing the curved panel portion 1211 and the arc top 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 arc top of the curved panel portion 1211. In this embodiment, when a filling portion 17 or an inner supporting portion 18 is provided on the inner side of the curved panel portion 1211, the filling portion 17 or the inner supporting portion 18 is close to the side of the middle frame 20 and is in contact with the curved panel portion 1211. The side of the filling portion 17 or the inner supporting portion 18 away from the middle frame 20 is in contact with the side of the support portion 122, but a first sub-set spacing c is set with the side of the composite layer 123 close to the middle frame 20, so that the filling portion 17 or the inner supporting portion 18 is used to fix the position of the inner side surface of the curved panel portion 1211, thereby reducing the probability of the curved panel portion 1211 shaking, and the filling portion 17 or the inner supporting portion 18 is not in contact with the composite layer 123, thereby preventing the filling portion 17 or the inner supporting portion 18 from entering the interior of the composite layer 123 due to the capillary effect during the manufacturing process, causing the interior of the composite layer 123 to be contaminated and / or peeled off.

[0122] In another embodiment of the present application, as shown in FIG29 , a filling portion 17 and an inner supporting portion 18 are provided on the inner side of the curved panel portion 1211. Along the direction from the inner side of the curved panel portion 1211 to the support portion 122, the inner supporting portion 18 and the filling portion 17 are arranged in sequence, so that the display device can select different materials according to the usage requirements of the space between the curved panel portion 1211 and the support portion 122 at different positions in the first direction X. Optionally, in one embodiment of the present application, the curing strength of the inner supporting portion 18 is greater than the curing strength of the filling portion 17, thereby reducing the risk of the inner supporting portion 18 entering the interior of the composite layer 123 due to capillary effect during the manufacturing process, resulting in contamination and / or peeling of the composite layer 123. In other embodiments of the present application, as shown in Figure 30, the filling portion 17 and the inner supporting portion 18 are arranged in sequence along the direction from the inner side of the curved panel portion 1211 to the supporting portion 122. Optionally, in this embodiment, the curing strength of the filling portion 17 is greater than the curing strength of the inner supporting portion 18, thereby reducing the risk of the filling portion 17 entering the interior of the composite layer 123 due to capillary effect during the manufacturing process, causing the interior of the composite layer 123 to be contaminated and / or peeled off.

[0123] For example, in one embodiment of the present application, as shown in Figure 29, in the first direction X, when the length of the support portion 122 is greater than the length of the composite layer 123, the boundary line between the filling portion 17 and the inner support portion 18 is flush with the end surface of the support portion 122 facing the curved panel portion 1211, so as to facilitate the control of the boundary line between the filling portion 17 and the inner support portion 18 when making the filling portion 17 and the inner support portion 18.

[0124] In another embodiment of the present application, as shown in FIG31 , a filling portion 17 and an inner supporting portion 18 are provided on the inner side of the curved panel portion 1211. The filling portion 17 and the inner supporting portion 18 are arranged in sequence along the direction from the backlight side of the cover plate 11 to the support platform 21. In another embodiment of the present application, as shown in FIG32 , the inner supporting portion 18 and the filling portion 17 are arranged in sequence along the direction from the backlight side of the cover plate 11 to the support platform 21, so that the display device can select corresponding materials according to the usage requirements of different positions in the first direction X between the curved panel portion 1211 and the support portion 122.

[0125] Optionally, in one embodiment of the present application, in the thickness direction Y of the cover plate 11, the maximum lengths of the filling portion 17 and the inner supporting portion 18 are equal, that is, the filling portion 17 occupies half of the accommodation space formed by the curved panel portion 1211, the support portion 122 and the composite layer 123, and the inner supporting portion 18 occupies half of the accommodation space formed by the curved panel portion 1211, the support portion 122 and the composite layer 123, so that the filling portion 17 and the inner supporting portion 18 are evenly distributed in the accommodation space formed by the curved panel portion 1211, the support portion 122 and the composite layer 123.

[0126] Based on any of the above embodiments, in one embodiment of the present application, as further shown in FIG32 , 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 facing away from the cover plate 11, and is used to fix the shape of the first panel portion 1212 when the display panel 121 is a flexible display screen. The second support portion 1222 is located on the side of the second panel portion 1213 facing the cover plate 11, and is used to fix the shape of the second panel portion 1213 when the display panel 121 is a flexible display screen. For example, 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 and the second end are flush, thereby facilitating the fabrication of the support portion 122 and the composite layer 123.

[0127] In another embodiment of the present application, as shown in Figure 33, the end of the first support portion 1221 close to the curved panel portion 1211 is the first end A, and the end of the second support portion 1222 close to the curved panel portion 1211 is the second end B. In the thickness direction Y of the display panel 121, the first end A and the second end B are staggered so as to reduce the area of ​​the border area of ​​the display device by setting the relative positions of the first end A and the second end B.

[0128] Optionally, in one embodiment of the present application, as further shown in FIG. 33 , the curved panel portion 1211 is provided with a curved top portion 12110, and the first end A of the first support portion 1221 is closer to the curved top portion 12110 of the curved panel portion 1211 than the second end B of the second support portion 1222. In actual production, in the first direction X, the distance from the end of the cover plate 11 away from the curved panel portion 1211 to the curved panel portion 1211 is fixed. In this embodiment, the first end A of the first support portion 1221 is closer to the curved top portion 12110 of the curved panel portion 1211 than the second end B of the second support portion 1222. This allows the second support portion 1222, the composite layer 123, and other structures to move toward the support portion 122 away from the curved panel portion 1211, thereby reducing the maximum distance of the curved panel portion 1211 in the first direction X, thereby reducing the length of the cover plate 11 in the first direction X, and ultimately reducing the area of ​​the border region of the display device while maintaining a fixed display area.

[0129] For example, in one embodiment of the present application, as shown in FIG33 , the curved panel portion 1211 includes a first curved plate segment 12111 and a second curved plate segment 12112, the first curved plate segment 12111 is connected to the first panel portion 1212, the second curved plate segment 12112 is connected to the second panel portion 1213, and the curvature radius of the first curved plate segment 12111 is different from the curvature radius of the second curved plate segment 12112, so as to reduce the area of ​​the border area of ​​the display device by setting the curvature radius of the first curved plate segment 12111 and the second curved half segment 12112.

[0130] Optionally, in one embodiment of the present application, as shown in Figure 33, the curvature radius of the first bent plate segment 12111 is smaller than the curvature radius of the second bent plate segment 12112, so that under the premise that the display area of ​​the display panel 121 is fixed, by reducing the curvature radius of the first bent plate segment 12111, the second support portion 1222, the composite layer 123 and other structures as a whole move toward the support portion 122 away from the curved panel portion 1211, thereby reducing the maximum distance of the curved panel portion 1211 in the first direction X, and then reducing the length of the cover plate 11 in the first direction X, and finally reducing the area of ​​the border area of ​​the display device under the premise that the display area is fixed.

[0131] For example, in one embodiment of the present application, the curvature radius of the second bending plate segment 12112 is in the range of 0.15 mm to 0.3 mm, so as to avoid the curvature radius of the second bending plate segment 12112 being too small, resulting in the second bending plate segment 12112 being bent dead, causing the signal line of the second bending plate segment 12112 to be broken, and at the same time avoid the curvature radius of the second bending plate segment 12112 being too large, thereby increasing the area of ​​the border area of ​​the display device.

[0132] Optionally, in one embodiment of the present application, the curvature radius of the first bending plate segment 12111 is in the range of 0.05mm to 0.2mm, so as to ensure that the curvature radius of the first bending plate segment 12111 is smaller than the curvature radius of the second bending plate segment, thereby avoiding the curvature radius of the first bending plate segment 12111 being too small, resulting in the first bending plate segment 12111 being bent dead, causing the signal line of the first bending plate segment 12111 to be broken, and at the same time avoiding the curvature radius of the first bending plate segment 12111 being too large, thereby increasing the area of ​​the border area of ​​the display device.

[0133] On the basis of any of the above embodiments, in one embodiment of the present application, as shown in Figure 34, at least one first protrusion 132 is provided on the side of the encapsulation portion 13 facing away from the cover plate 11, and a first groove is provided on the side of the support platform 21 close to the cover plate 11, and at least part of the first protrusion 132 is located in the first groove, so as to enhance the fixed connection performance between the encapsulation portion 13 and the support platform 21 through the cooperation between the first protrusion 132 and the first groove.

[0134] Optionally, in the cross-sectional view of the display device, as shown in Figure 34, the size of the first protrusion 132 in the first direction X gradually decreases along the direction of the encapsulation portion 13 away from the cover plate 11. Exemplarily, the first protrusion 132 includes a first surface and a second surface opposite to each other in the first direction X. In the first direction X, the distance between the first surface and the second surface gradually decreases to facilitate at least partial insertion of the first protrusion 132 into the first groove.

[0135] In one embodiment of the present application, as further shown in FIG34 , the angle between the first surface of the first protrusion 132 and the plane on which the cover plate 11 lies is an acute angle, and the angle between the second surface of the first protrusion 132 and the plane on which the cover plate 11 lies is also an acute angle. In another embodiment of the present application, as shown in FIG35 , the angle between the first surface of the first protrusion 132 and the plane on which the cover plate 11 lies is a right angle, and the angle between the second surface of the first protrusion 132 and the plane on which the cover plate 11 lies is an acute angle. In yet another embodiment of the present application, as shown in FIG36 , the angle between the first surface of the first protrusion 132 and the plane on which the cover plate 11 lies is an acute angle, and the angle between the second surface of the first protrusion 132 and the plane on which the cover plate 11 lies is a right angle.

[0136] In the above embodiment, as shown in Figure 35, when the angle between the first surface of the first protrusion 132 and the plane where the cover plate 11 is located is a right angle, the first surface of the first protrusion 132 can be located in the same vertical plane as the end surface of the support platform 21 away from the middle frame 20.

[0137] Based on any of the above embodiments, in one embodiment of the present application, as shown in FIG37 , the display device further includes: a connecting plate 40, the connecting plate 40 being located on a side of the second panel portion 1213 away from the cover plate 11, so as to support 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 further located within the encapsulating portion 13 to improve the fixed connection performance between the connecting plate 40 and the encapsulating portion 13, and at the same time, the connecting plate 40 can be used to support the encapsulating portion 13 in the thickness direction Y of the cover plate 11, thereby reducing the bearing force on the support platform 21.

[0138] Illustratively, in one embodiment of the present application, the connecting plate 40 is a sheet metal part to improve the supporting strength of the connecting plate 40 .

[0139] Optionally, in one embodiment of the present application, the display device further includes: an adhesive glue 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 .

[0140] In one embodiment of the present application, as shown in FIG38 , the connecting plate 40 includes a plate body 41 and at least one second protrusion 42 located on a surface of the plate body 41. Optionally, in one implementation, the second protrusion 42 extends in a direction away from the cover plate 11 and is directly embedded in the support platform 21, thereby utilizing the second protrusion 42 to enhance the fixed connection performance between the connecting plate 40 and the support platform 21.

[0141] In another embodiment of the present application, the second protrusion 42 extends in a direction away from the cover plate 11, and the second protrusion 42 is indirectly embedded in the support platform 21, so that when the second protrusion 42 enhances the fixed connection performance between the connecting plate 40 and the support platform 21, the fixed connection performance between the second protrusion 42 and the support platform 21 is enhanced by the connecting member between the second protrusion 42 and the support platform 21. Optionally, in one embodiment of the present application, the second protrusion 42 is embedded in the support platform 21 via a glue layer, that is, a glue layer is provided between the second protrusion 42 and the support platform 21, so as to enhance the fixing strength between the second protrusion 42 and the support platform 21 via the glue layer.

[0142] Based on any of the above embodiments, in one embodiment of the present application, as shown in Figure 39, the second protrusion 42 and the encapsulation portion 13 at least partially overlap in the thickness direction Y of the cover plate 11, and at least part of the second protrusion 42 is located in the encapsulation portion 13, so as to utilize the second protrusion 42 to simultaneously enhance the fixed connection performance between the connecting plate 40 and the encapsulation portion 13 and the fixed connection performance between the connecting plate 40 and the support platform 21.

[0143] Optionally, in one embodiment of the present application, as further shown in FIG39 , the second protrusion 42 passes through the portion of the encapsulating portion 13 between the plate body 41 and the support platform 21 and extends into the support platform 21, thereby simultaneously achieving the second protrusion 42 being at least partially located within the encapsulating portion 13 and being embedded in the support platform 21. In other embodiments of the present application, the second protrusion 42 may also be formed in other ways to simultaneously achieve the second protrusion 42 being at least partially located within the encapsulating portion 13 and being embedded in the support platform 21.

[0144] In another embodiment of the present application, as shown in Figure 38, the second protrusion 42 and the encapsulation portion 13 do not overlap in the thickness direction Y of the cover plate 11, so that the second protrusion 42 and the display module 12 overlap in the thickness direction Y of the cover plate 11, thereby increasing the supporting strength of the connecting plate 40 to the display module 12.

[0145] Optionally, in one embodiment of the present application, there is a third set spacing between the second protrusion 42 and the encapsulation portion 13 in the first direction X, and the length of the third set spacing ranges from 0.1 mm to 0.5 mm, so as to reduce the area of ​​the border area of ​​the display device, thereby facilitating the display device to achieve a narrow border.

[0146] For example, in one embodiment of the present application, as shown in FIG40 , the second protrusion 42 at least partially overlaps with at least two functional layers of the composite layer 123, so that the second protrusion 42 can support the composite layer 123, the support portion 122, and the display panel 121, thereby improving the support strength of the connecting plate 40 for the display module 12. In other embodiments of the present application, the second protrusion 42 may at least partially overlap with one functional layer of the composite layer 123, or may not overlap with the composite layer 123, depending on the circumstances.

[0147] Optionally, in one embodiment of the present application, as shown in Figure 40, the support platform 21 is provided with a first end 212 and a second end 211, the first end 212 of the support platform 21 is located on a side close to the middle frame 20, and the second end 211 of the support platform 21 is located on a side away from the middle frame 20, and the distance f between the second protrusion 42 and the first end 212 of the support platform 21 is greater than the distance e between the second protrusion 42 and the second end 211 of the support platform 21, so that the second protrusion 42 is located in the area of ​​the plate body 41 close to the composite layer 123, thereby improving the stability of the connecting plate 40 through the connecting end between the plate body 41 and the middle frame 20 and the second protrusion 42, and at the same time, reducing the probability of the display panel 121 being warped at both ends in the first direction X when the display panel 121 is pressed.
