[0064] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] In the following description, many specific details are set forth to facilitate a full 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 connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0066] As described in the background technology section, how to reduce the area of ​​the border region of a display panel has become a research hotspot for those skilled in the art.

[0067] Currently, a display device generally includes a middle frame and a display assembly, wherein the display assembly includes a cover plate and a display module, and the display module is located on the backlight side of the cover plate. In specific applications, the display assembly is assembled on the middle frame through the cover plate to form a display device.

[0068] like Figure 1 As shown, in the direction perpendicular to the plane where the display device is located, the middle frame includes a first part 01 and a second part 02, wherein the inner diameter of the first part 01 is larger than the inner diameter of the second part 02, thereby forming a step surface at the junction area of ​​the first part 01 and the second part 02, and the cover plate 03 is overlapped on the step surface by the caulking glue 04 and assembled with the middle frame. In this assembly method, the distance D1 between the end of the display component facing the middle frame and the side surface of the middle frame away from the display component is large, resulting in a larger size of the frame area of ​​the existing display device, and then resulting in a larger black border corresponding to the frame area of ​​the existing display device, which affects the user experience.

[0069] In view of this, an embodiment of the present application provides a display device, such as Figure 2 As shown, the display device comprises:

[0070] The display assembly 10 comprises a cover plate 11, a display module 12 and an encapsulation portion 13, wherein 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 part of the encapsulation portion 13 is located on the backlight side of the cover plate 11, and the encapsulation portion 13 at least partially surrounds the display module 12;

[0071] 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 in the thickness direction Y of the cover plate 11.

[0072] Optionally, in an embodiment of the present application, the cover plate is a glass cover plate, and the encapsulation portion is a solid glue portion, that is, formed by curing glue, but the present application does not limit this and it depends on the specific situation.

[0073] It should be noted that, in the present embodiment, the encapsulation portion may be partially located on the backlight side of the cover plate, or may be entirely located on the backlight side of the cover plate; similarly, the encapsulation portion may partially surround the display module, or may entirely surround the display module. The present application does not impose any limitation on this, and it depends on the specific circumstances.

[0074] In the display device provided in the embodiment of the present application, there is a first overlapping area between the support platform and the display module in the thickness direction of the cover plate, so that the support platform and the display module partially overlap, thereby reducing the distance D2 between the end of the display module facing the middle frame and the side surface of the middle frame facing the display module in a plane parallel to the cover plate, and further reducing the distance D3 between the end of the display module facing the middle frame and the side surface of the middle frame away from the display module, so as to reduce the area of ​​the border region of the display device in the plane parallel to the cover plate, which is suitable for the development trend of narrow borders.

[0075] Optionally, based on the above embodiments, 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 0.1-0.4, 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.

[0076] Specifically, 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 0.15-0.3, so as to further 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 frame, so as to achieve 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 frame.

[0077] 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 mm, so that the support platform 21 has better supporting strength for the display module 12 .

[0078] Specifically, 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 .

[0079] Specifically, in one embodiment of the present application, Figure 3 As shown, the display module 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.

[0080] Based on the above embodiments, in one embodiment of the present application, Figure 4 As shown, the support platform 21 and the curved panel portion 1211 of the display panel 121 in the display module 12 have an overlapping area, and there is no overlap with the composite layer 123 and the support portion 122, so as to reduce the extension length of the support platform 21 toward the backlight side of the display module 12, and provide more design space for the internal structure of the display device. It should be noted that, in this embodiment, the overlapping area between the support platform 21 and the curved panel portion 1211 is the first overlapping area 30.

[0081] In another embodiment of the present application, continue as Figure 3 As shown, 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 further reduce the distance between the end of the display module facing the middle frame and the surface of the middle frame facing the display module in the plane parallel to the cover plate by increasing the extension length of the support platform 21 toward the backlight side of the display module 12, thereby reducing the distance between the end of the display module facing the middle frame and the surface of the middle frame away from the display module, so as to reduce the area of ​​the border region of the display device in the plane parallel to the cover plate, thereby realizing a narrow border; it should be noted that, in this embodiment, the overlapping area of ​​the support platform 21 and the curved panel portion 1211 and the overlapping area of ​​the support platform 21 and the composite layer 123 and / or the support portion 122 together constitute the first overlapping area 30.

[0082] Optionally, based on the above embodiment, in one embodiment of the present application, Figure 3 and Figure 5 As shown, in the first direction X, the length of the composite layer 123 is less than the length of the support portion 122. Specifically, in an implementation of the present embodiment, a second overlapping region 31 exists between the support platform 21 and the composite layer 123, thereby further reducing the frame area of ​​the display device and realizing a narrow frame. In the thickness direction Y of the cover plate 11, the support platform 21 is utilized to provide a certain support effect to the composite layer 123, thereby improving the stability of the display module in the thickness direction Y of the cover plate. However, the present application does not limit this, and it depends on the specific circumstances.

[0083] It should be noted that, in the above-mentioned embodiment, among the multiple functional layers included in the composite layer, the sizes of different functional layers in the first direction may be the same, such as Figure 3 as shown, or may be different, such as Figure 5Optionally, in one embodiment of the present application, the support platform 21 and the composite layer 123 have a second overlapping region in the thickness direction Y of the cover plate 11, including the support platform 21 and at least one functional layer in the composite layer 123 having an overlapping region 311 in the thickness direction Y of the cover plate 11, so as to achieve the overlap of the support platform and the composite layer.

[0084] Specifically, on the basis of the above embodiments, in one embodiment of the present application, the functional layer in the composite layer includes a first functional layer 1231. In the first direction X, the first functional layer 1231 is the functional layer with the longest length in the composite layer 123, that is, the distance between the first functional layer 123 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.

[0085] Based on the above embodiments, in one embodiment of the present application, Figure 6 As shown, the support platform 21 only has an overlapping area 311 with the first functional layer 1231 in the composite layer 123, so as to take into account the supporting strength of the support platform 21 for the display module 12 and the occupied area of ​​the support platform 21 inside the display device. In other embodiments of the present application, such as Figure 5 As shown, the support platform 21 has an overlapping area 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 supporting strength of the support platform 21 to the display module 12, and further improve the stability of the display module 12 in the thickness direction Y of the cover plate 11. The present application does not limit this, and it depends on the specific situation.

[0086] Optionally, in one embodiment of the present application, continue as Figure 5 As shown, 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 display module 12 by the support platform 21, and further improving the stability of the display module 12 in the thickness direction Y of the cover plate 11. The present application does not impose any limitation on this, and it depends on the specific circumstances.

[0087] Specifically, in one embodiment of the present application, in the first direction X, the numerical range of the second overlapping area is 0.2-0.4 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, but the present application does not limit this, and it depends on the specific situation.

[0089] Specifically, based on the above embodiment, in one embodiment of the present application, continue as follows Figure 6 As shown, 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 end 211 of the support platform 21 away from the middle frame 20 is located on the side of the end of the curved panel portion 1211 away from the middle frame 20 in the first direction, so as to ensure the supporting effect of the support platform 21 on the curved panel portion 211; in another embodiment of the present application, continue as Figure 4 As shown, 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 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 supporting effect of the support platform 21 on the curved panel portion 1211, but the present application does not limit this and it depends on the specific situation.

[0090] Based on the above embodiments, in one embodiment of the present application, Figure 7 As shown, the curved panel portion 1211 is provided with an arc top portion, and a distance D4 between the arc top portion and the side of the middle frame 20 close to the curved panel portion 1211 is smaller than a distance D5 between the arc top portion and the end portion 211 of the support platform 21 away from the side of the middle frame 20, so as to improve the support strength of the support platform 21 for the display module 12; however, the present application is not limited to this. In other embodiments of the present application, such as Figure 8As shown, the curved panel portion 1211 is provided with an arc top portion, and a distance D4 between the arc top portion and the side of the middle frame 20 close to the curved panel portion 1211 may also be greater than a distance between the arc top portion and an end portion 211 of the support platform 21 away from the side of the middle frame 20, so as to reduce the length of the support platform 21 in the first direction X, thereby reducing the space inside the display device that the support platform 21 needs to occupy, depending on the specific circumstances.

[0091] Based on any of the above embodiments, in one embodiment of the present application, the composite layer includes at least one or more of a metal layer, an adhesive layer, a copper foil, a foam and a graphite species.
