[0040] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Please refer to Figures 1-2 , Figure 1 This is a partial top view of a specific embodiment of the display device provided in this application; Figure 2 for Figure 1 The display device is shown in cross-sectional view along the AA direction.

[0042] This application provides a display device, including:

[0043] The housing 1 has upper connecting grooves 11 at both ends in the first direction;

[0044] The middle frame 2 includes an upper housing connecting part 21 and a display screen connecting part 22. The upper housing connecting part 21 is connected to the housing 1 and is provided in the upper connecting groove 11 at the corresponding end at least along the first direction.

[0045] The display screen 3 has two ends in the first direction connected to at least part of the upper sidewall 211 of the corresponding display screen connection part 22.

[0046] In the display device of this application embodiment, the middle frame 2 is disposed between the housing 1 and the display screen 3 at the corresponding ends, serving to connect the housing 1 and the display screen 3. When connecting the housing 1, the middle frame 2 is disposed in the upper connecting groove 11 at the corresponding end at least along the first direction. The two ends of the display screen 3 in the first direction are connected to the upper sidewall 211 of the corresponding display screen connecting part 22. In this way, the middle frame 2 does not need to occupy the space between the housing 1 and the display screen 3 in the first direction, so that the size of the display screen 3 can be further increased, creating a display device with a large screen.

[0047] The upper housing connecting part 21 is provided at least along the first direction in the upper connecting groove 11 at the corresponding end. The upper housing connecting part 21 and the upper connecting groove 11 can be interference fit or transition fit. The upper housing connecting part 21 can extend into the interior of the upper connecting groove 11 or be embedded in the interior of the upper connecting groove 11, etc.

[0048] Depend on Figure 2 As can be seen, the housing 1 has an adhesive surface a for bonding the glass screen, and the upper connecting groove 11 penetrates the adhesive surface a. Therefore, in order to avoid interference with the installation of the glass screen, the upper housing connecting part 21 is provided inside the upper connecting groove 11 in the vertical direction, so that the upper housing connecting part 21 is not higher than the adhesive surface a, which facilitates the installation of the glass screen.

[0049] Please continue to refer to this. Figure 2 In this embodiment, the upper connecting groove 11 includes a first groove 11a and a second groove 11b that are interconnected. The first groove 11a is disposed on the upper side wall of the housing 1, and the second groove 11b is disposed on the side wall of the housing 1 facing the display screen 3.

[0050] The upper housing connecting part 21 includes a first connecting part 211 and a second connecting part 212. The second connecting part 212 connects the first connecting part 211 and the display screen connecting part 22. The first connecting part 211 is located inside the first groove 11a, and the second connecting part 212 is located inside the second groove 11b.

[0051] As configured above, the second connecting part 212 and the second groove 11b extend in the vertical direction, and the first connecting part 211 and the first groove 11a extend in the first direction. The upper housing connecting part 21 and the upper connecting groove 11 are approximately inverted L-shaped. The lower side wall of the first groove 11a forms a support wall. When the first connecting part 211 is located inside the first groove 11a and the second connecting part 212 is located inside the second groove 11b, the first connecting part 211 is supported by the lower side wall of the first groove 11a, thereby allowing the upper housing connecting part 21 to be hung inside the corresponding upper connecting groove 11, thus realizing the connection between the upper housing connecting part 21 and the housing 1.

[0052] Meanwhile, the second connecting part 212 is located inside the second groove 11b, which does not require occupying the space between the housing 1 and the display screen 3 in the first direction, allowing the size of the display screen 3 to be further increased, thus creating a display device with a large screen.

[0053] Please continue to refer to this. Figure 1 and Figure 2 In this embodiment, the length of the first groove 11a is greater than the length of the second groove 11b. A limiting wall A is formed between the first groove 11a and the second groove 11b, with the opening end facing away from the second groove 11b. In the extending direction of the middle frame 2, the length of the first connecting part 211 is greater than the length of the second connecting part 212. The length of the first connecting part 211 matches the length of the first groove 11a, and the length of the second connecting part 212 matches the length of the second groove 11b. In the installed state, the side wall of the first connecting part 211 facing the opening end of the second groove 11b abuts against the limiting wall A.

[0054] It should be noted that the length direction of the first groove 11a and the second groove 11b is the second direction, the extension direction of the middle frame 2 is the second direction, and the first direction and the second direction are perpendicular.

[0055] As configured above, the closed end wall and the limiting wall A of the first groove 11a can limit the first connecting part 211 in the first direction, ensuring that the first connecting part 211 and the first groove 11a are in a limited state along the first direction, preventing the upper housing connecting part 21 from coming out of the inside of the upper connecting groove 11 along the first direction, improving the connection stability between the middle frame 2 and the housing 1, and ensuring the reliable installation of the display screen 3.

[0056] As mentioned above, the length of the first connecting part 211 matches the length of the first groove 11a. Specifically, the length of the first connecting part 211 can be slightly smaller than the length of the first groove 11a. This facilitates the placement of the first connecting part 211 inside the first groove 11a, ensuring smooth installation of the first connecting part 211. It also ensures that the first connecting part 211 will not wobble significantly when placed in the first groove 11a, thereby improving the installation stability of the middle frame 2 and thus improving the installation stability of the display screen 3.

[0057] As mentioned above, the length of the second connecting part 212 matches the length of the second groove 11b. Specifically, the length of the second connecting part 212 can be slightly smaller than the length of the second groove 11b. This facilitates the placement of the second connecting part 212 inside the second groove 11b, ensuring smooth installation of the second connecting part 212. It also ensures that the second connecting part 212 will not wobble significantly when placed in the second groove 11b, thus ensuring the installation stability of the middle frame 2 and consequently the installation stability of the display screen 3.

[0058] Furthermore, in this embodiment, the upper housing connecting part 21 and the upper connecting groove 11 are bonded and fixed.

[0059] In this way, the upper housing connecting part 21 and the housing 1 are fixed by adhesive, so as to achieve a reliable connection between the middle frame 2 and the housing 1 and ensure the reliable installation of the display screen 3.

[0060] The bonding positions of the upper shell connecting part 21 and the upper connecting groove 11 are not limited. For example, in this embodiment, the lower side wall of the first connecting part 211 and the lower side wall of the first groove 11a are bonded and fixed. Under the load-bearing force of the upper shell connecting part 21, the lower side wall of the first connecting part 211 and the lower side wall of the first groove 11a can be bonded more firmly, thereby improving the bonding reliability of the middle frame 2 and the shell 1.

[0061] In other embodiments of this application, the opposite end walls of the second connecting portion 212 and the second groove portion 11b can also be bonded and fixed to improve the bonding reliability of the upper housing connecting portion 21 and the upper connecting groove 11.

[0062] In some embodiments of this application, the lower sidewall of the first connecting part 211 and the lower sidewall of the first groove 11a can be bonded and fixed by double-sided adhesive; in other embodiments of this application, the lower sidewall of the first connecting part 211 and the lower sidewall of the first groove 11a can be bonded and fixed by dispensing adhesive.

[0063] Furthermore, in this embodiment, the middle frame 2 also includes a structural reinforcement (not shown in the figure), which is disposed between the second connecting part 212 and the display screen connecting part 22.

[0064] As described above, the structural reinforcement can improve the connection strength between the second connecting part 212 and the display screen connecting part 22, improve the connection stability between the second connecting part 212 and the display screen connecting part 22, and ensure the installation reliability of the display screen 3.

[0065] In some embodiments of this application, the structural reinforcement can be a right-angled triangle, with one right-angled side of the structural reinforcement connected to the second connecting part 212, and the other right-angled side connected to the display screen connecting part 22.

[0066] Furthermore, there is no limit to the number of structural reinforcements provided in the middle frame 2. For example, the number of structural reinforcements can be at least one, as long as the structural reliability of the middle frame 2 can be guaranteed.

[0067] Please refer to Figure 1 and Figure 3 , Figure 1 This is a partial top view of a specific embodiment of the display device provided in this application; Figure 3 for Figure 2 The display device is shown in cross-sectional view in the BB direction.

[0068] In this embodiment, the middle frame 2 also includes a lower housing connecting part 23, which is connected to the display screen connecting part 22. The lower sidewalls at both ends of the housing 1 in the first direction are provided with lower connecting grooves 12, which penetrate the sidewalls of the housing 1 facing the display screen 3. The lower housing connecting part 23 is located inside the lower connecting groove 12 and abuts against the upper wall 121 of the lower connecting groove 12.

[0069] As configured above, when the upper housing connecting part 21 is mounted inside the corresponding upper connecting groove 11, the lower side wall of the first groove 11a serves as a lower limit for the middle frame 2. When the lower housing connecting part 23 is located inside the lower connecting groove 12 and abuts against the upper wall 121 of the lower connecting groove 12, the upper wall 121 of the lower connecting groove 12 serves as an upper limit for the middle frame 2. In this way, the upper housing connecting part 21 and the lower housing connecting part 23 achieve reliable vertical positioning of the middle frame 2 and the housing 1, preventing the middle frame 2 from moving up and down, ensuring reliable connection between the middle frame 2 and the housing 1, and thus ensuring reliable installation of the display screen 3.

[0070] As can be seen from the foregoing, the upper housing connecting part 21 and the upper connecting groove 11 are bonded and fixed to achieve relative fixation of the middle frame 2 and the housing 1. After assembly, the glass screen is bonded to the bonding surface a of the housing 1. The glass screen can also play a role in limiting the position of the middle frame 2. Therefore, in some embodiments of this application, it is also feasible not to provide the lower housing connecting part 23.

[0071] When the middle frame 2 is provided with the lower housing connecting part 23, the number of lower housing connecting parts 23 is not limited. There can be at least one lower housing connecting part 23. The lower housing connecting part 23 is located on at least one side of the upper housing connecting part 21, as long as the middle frame 2 and the housing 1 can be reliably limited in the vertical direction.

[0072] Depend on Figure 1 As can be seen, in this embodiment, there are two or more lower housing connecting parts 23. The two or more lower housing connecting parts 23 are respectively disposed on both sides of the upper housing connecting part 21. The two or more lower housing connecting parts 23 can all play a limiting role for the middle frame 2, so that the middle frame 2 is in a state of force balance in the extension direction, thereby improving the installation stability of the middle frame 2 installed on the housing 1.

[0073] Please continue to refer to this. Figure 3 In this embodiment, the lower housing connection portion 23 extends obliquely upward along the direction away from the display screen connection portion 22.

[0074] As shown above, the lower housing connecting part 23 extends upward at an angle, the lower connecting groove 12 extends to a greater depth from bottom to top, and the structure above the lower connecting groove 12 has a smaller thickness, which helps to reduce the weight of the housing 1 and the overall weight of the display device, thus meeting the requirements for lightweighting.
