[0007] The present application provides a display device, including a display screen and a frame structure; the frame structure includes a frame, a circuit board assembly and two first seals, the frame defines a window area for setting up the display screen, and the circuit board assembly is set in the frame; the frame includes a lower frame located below the display screen and two side frames located on the sides of the display screen, the bottom of one side frame is connected to one end of the lower frame, and the connection between each side frame and the lower frame forms a first hollow area located on the front of the display screen, and a first seal blocks a first hollow area.

[0008] As an optional embodiment, the first sealing member includes a first sealing body that seals the first hollowed-out area; a limiting structure is provided between the first sealing body and the frame, the limiting structure being configured to limit the relative position between the first sealing member and the frame. The provision of the limiting structure thus facilitates installation of the first sealing member, thereby improving the assembly efficiency of the frame structure and, consequently, the display device provided herein.

[0009] As an optional embodiment, the limiting structure includes a first limiting structure, which is disposed between the first sealing body and the lower frame; the first limiting structure is configured to limit the relative position of the first sealing member and the lower frame in the height direction of the display screen. In this way, by limiting the relative position of the first sealing member and the lower frame in the height direction of the display screen, the relative position of the first sealing member and the frame in the height direction of the display screen can be limited.

[0010] As an optional embodiment, the first limiting structure includes a first limiting protrusion formed on the lower frame and a first extension portion connected to the first sealing body; the protruding direction of the first limiting protrusion is consistent with the thickness direction of the display screen, and the end of the first extension portion away from the first sealing body abuts against the first limiting protrusion.

[0011] As an optional embodiment, the limiting structure further includes a second limiting structure, disposed between the first sealing body and the side frame; the second limiting structure is configured to limit the relative position of the first sealing member and the side frame in the width direction of the display screen.

The second connecting plate 722 is configured to form the outer surface of the frame 1, wherein the first connecting plate 721 is connected to the second connecting portion 612, and the second connecting plate 722 forms At the corner of the outer surface of the frame 1; the mating part 71 includes a first mating plate 711 and a second mating plate 712, the first mating plate 711 is connected to the second connecting plate 722, the plate surface direction of the first mating plate 711 is consistent with the plate surface direction of the first covering part 621, and the first mating plate 711 is attached to the outer side of the first covering part 621; the second mating plate 712 is connected to the side of the first mating plate 711, the plate surface direction of the second mating plate 712 is consistent with the plate surface direction of the second covering part 622, and the second mating plate 712 is attached to the outer side of the second covering part 622.

[0072] In order to enable the end of the second connecting member 7 to extend into the side frame 13, in this embodiment, the mating portion 71 also includes a third mating plate 713, which is connected between the first mating plate 711 and the second mating plate 712. The third mating plate 713 is blocked at the front end of the covering portion 62 and extends into the side frame 13.

[0073] In some optional embodiments, to enhance the structural strength of the second connector 7, the mating portion 71 may further include a reinforcing rib 714 disposed between the first mating plate 711 and the third mating plate 713. The provision of the reinforcing rib 714 can thus enhance the strength of the mating portion 71, thereby further enhancing the structural strength of the second connector 7 in this embodiment.

[0074] It should be noted that, in order to further enhance the strength of the mating portion 71 , the aforementioned reinforcing ribs 714 may be multiple, with the multiple reinforcing ribs 714 being arranged at intervals.

[0075] Please continue to refer to Figure 13, which is a schematic diagram of the cooperation relationship between the first connector and the first sealing member in the display device provided in the embodiment of the present application. As shown in Figures 3, 8 and 13, it can be understood that the first connector 6 is mostly a plastic part, and therefore cannot effectively seal the corners of the display screen 4. Therefore, in some optional embodiments, the first sealing member 3 also includes a third extension 34, which is connected to the first sealing body 31 and extends toward the back of the display screen 4, and the third extension 34 is located between the cover portion 62 and the corner of the display screen 4; the third extension 34 is attached to the side of the cover portion 62 facing the window area 11, and the contour shape of the third extension 34 is adapted to the contour shape of the cover portion 62. In this way, by setting the third extension portion 34, the third extension portion 34 will be located between the corner of the display screen 4 and the cover portion 62. When the frame structure is assembled, the display screen 4 and the cover portion 62 will form a clamping force on the third extension portion 34, so that the third extension portion 34 can seal the display screen 4 and the cover portion 62, which can prevent liquid from entering the interior of the frame 1 from the second hollow area 8 to a certain extent, so that the display screen 4 can be touched normally.

[0076] When assembling the frame structure, the upper frame 14, the two side frames 13 and the lower frame 12 should first be connected together through the connecting structure, and then the first seal 3 should be pressed into place. Since the installation direction of the first seal 3 is from front to back, it is necessary to limit the relative position between the third extension portion 34 located on the rear side of the first seal 3 and the first connecting member 6.

[0077] Therefore, in some embodiments, a limiting surface 623 may be formed on the cover portion 62, and the end of the third extension portion 34 away from the first sealing body 31 abuts against the limiting surface 623, that is, the rear end of the third extension portion 34 abuts against the limiting surface 623. In this way, by providing the limiting surface 623, the relative position between the third extension portion 34 and the first connecting member 6 can be limited, thereby limiting the installation position of the first sealing member 3, thereby improving the assembly efficiency of the frame structure, and further improving the assembly efficiency of the display device 10 provided in this embodiment.

[0078] It should be noted that the above-mentioned limiting surface 623 can be parallel to the display surface of the display screen 4. Here, there is no specific limitation on the extending direction of the limiting surface 623.

In this way, the provision of the second seal 9 can prevent liquid from entering the frame 1 from the back of the display screen 4 to a certain extent.

[0080] Specifically, the second sealing member 9 includes a second sealing body 91. The contour of the second sealing body 91 matches the contour of the cover portion 62. The second sealing body 91 is larger than the cover portion 62, so that the second sealing body 91 abuts against the lower frame 12 and the side frames 13. This facilitates installation of the second sealing member 9. For example, in some embodiments, the second sealing member 9 can be bonded between the side frames 13 and the lower frame 12.

[0081] In a specific implementation of this embodiment, the second sealing body 91 includes a first sealing portion 911 and a second sealing portion 912, the second sealing portion 912 is connected to the rear side of the first sealing portion 911, the first sealing portion 911 abuts against the display screen 4, and the overall thickness of the first sealing portion 911 is greater than the overall thickness of the second sealing portion 912, so as to form a step surface 913 between the first sealing portion 911 and the second sealing portion 912.

[0082] To prevent deformation of the second sealing member 9 during installation, in some embodiments, a plurality of reinforcing portions 92 are provided on a side of the second sealing body 91 facing away from the cover portion 62. The plurality of reinforcing portions 92 are spaced apart along the extension direction of the first sealing body 31. The provision of the reinforcing portions 92 thus enhances the strength of the second sealing member 9 and prevents excessive deformation of the second sealing member 9 during installation.

[0083] Specifically, one end of the reinforcing portion 92 is connected to the stepped surface 913, and the other end of the reinforcing portion 92 extends obliquely toward the second sealing portion 912. Here, the shape of the reinforcing portion 92 is not particularly limited.

[0084] It should be noted that, in some embodiments, the first sealing member 3 and the second sealing member 9 can both be made of silicone. Here, the materials of the first sealing member 3 and the second sealing member 9 are not specifically limited.
