[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort, fall within the protection scope of the present application.

[0064] In the following description, a lot of specific details are set forth in order to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and a person of ordinary skill in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0065] As described in the background section, how to reduce the area of the frame region of the display panel has become a research hotspot for those skilled in the art.

[0066] Currently, display devices typically consist of a mid-frame 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 practical applications, the display assembly is attached to the mid-frame via the cover plate to form the display device.

[0067] like Figure 2 As shown, in a direction perpendicular to the plane of the display device, 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 stepped surface at the junction of the first part 01 and the second part 02. The cover plate 03 is overlapped on the stepped surface by sealant 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 surface of the middle frame away from the display component is large, resulting in a large bezel area size in the existing display device, which in turn results in a large black border corresponding to the bezel area in the existing display device, affecting the user experience.

[0068] In view of this, embodiments of this application provide a display device, such as... Figure 3 As shown, the display device includes:

[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 has at least a partial support platform 21 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.

[0071] Optionally, in one embodiment of this application, the cover plate is a glass cover plate and the encapsulation part is a solidified part, that is, formed by curing with adhesive. However, this application does not limit this and it depends on the specific circumstances.

[0072] It should be noted that, in this embodiment, the encapsulation portion may be partially located on the backlight side of the cover plate, or it may be entirely located on the backlight side of the cover plate; similarly, the encapsulation portion may partially surround the display module, or it may be entirely surrounding the display module. This application does not limit this, and it depends on the specific circumstances.

[0073] In the display device provided by the embodiment, the support table and the display module have a first overlapping area in the thickness direction of the cover plate, so that 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 the plane parallel to the plane of the cover plate is reduced, and 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 is also reduced, so that the area of the frame area of the display device in the plane parallel to the plane of the cover plate is reduced, which is suitable for the development trend of narrow frame.

[0074] Optionally, based on the above embodiment, in an 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 table 21 ranges from 0.1 to 0.4, so as to avoid that the gap between the middle frame 20 and the display module 12 is too small, the shaking of the middle frame 20 causes damage to the display module 12, and meanwhile, the gap between the middle frame 20 and the display module 12 is too large, which leads to a large area of the frame area of the display device, which is not conducive to realizing narrow frame.

[0075] Specifically, in an 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 table 21 ranges from 0.15 to 0.3, so as to further balance between the shaking of the middle frame 20 not causing damage to the display module 12 and the display device having narrow frame.

[0076] Optionally, in an embodiment of the present application, in the first direction X, the length of the first overlapping area 30 is not less than 0.5 mm, so as to make the support table 21 have better support strength on the display module 12.

[0084] On the basis of the above embodiment, in an embodiment of the present application, as shown in Figure 5 , the support table 21 only has an overlapping area 311 with the first functional layer 1231 in the composite layer 123, so as to balance the support strength of the support table 21 on the display module 12 and the occupied area of the support table 21 in the display device, and in other embodiments of the present application, as shown in Figure 5 , the support table 21 not only has an overlapping area 311 with the first functional layer 1231 in the composite layer 123, but also has an overlapping area 312 with other functional layers in the composite layer 123, so as to enhance the support strength of the support table 21 on the display module 12 and further improve the stability of the display module 12 in the thickness direction Y of the cover plate 11, which is not limited in the present application and is determined according to the specific situation.

[0085] Optionally, in an embodiment of the present application, as shown in Figure 6 , the support table 21 and at least two functional layers in the composite layer 123 have at least partial overlapping in the thickness direction Y of the cover plate 11, so as to increase the number of functional layers in the composite layer 123 overlapping with the support table 21, improve the support strength of the support table 21 on the display module 12, and further improve the stability of the display module 12 in the thickness direction Y of the cover plate 11, which is not limited in the present application and is determined according to the specific situation.

[0086] Specifically, in an embodiment of the present application, in the first direction X, the numerical range of the second overlapping area is 0.2-0.4mm, so as to make the support table 21 have better support effect on the composite layer 123 and improve the stability of the display module 12 in the thickness direction Y of the cover plate 11, but the present application is not limited thereto and is determined according to the specific situation.

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 along the first direction X. That is, in this embodiment, the projection of the curved panel portion 1211 on the plane of the cover plate 11 is located within the projection range of the support platform 21 on the plane of the cover plate 11. This is to maximize the support effect of the support platform 21 on the curved panel portion 1211 while reducing the bezel area of ​​the display device and achieving a narrow bezel, thereby improving the stability of the curved panel portion 1211 in the thickness direction of the cover plate 11.
