Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0036] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] like Figures 1 to 10 As shown, according to the first aspect of the present application, the present application provides a curved screen, including a display module 10, a central control box 30 and a corner frame 20, the corner frame 20 has an outer end surface and an inner peripheral surface relative to each other, and a receiving space defined at least by the inner peripheral surface, the central control box 30 is installed in the receiving space, the display module 10 is arranged on the outer end surface and is electrically connected to the central control box 30, so that the display module 10 can obtain a signal from the central control box 30 and display a picture;

[0038] In this embodiment, a first assembly part 31 is provided on the central control box 30, and a second assembly part is provided on the corner frame 20. The central control box 30 can be detachably installed in the receiving space through the cooperation between the second assembly part and the first assembly part 31, so that when the central control box 30 fails, the maintenance personnel can directly remove the central control box 30 from the corner frame 20 for maintenance, without removing the entire corner frame 20 from the curved screen. This is not only simple and convenient to operate, but also saves a lot of operation time.

[0039] It should be noted that the first assembly part 31 can be a bolt structure, and the second assembly part can be a screw hole structure matching the bolt structure; or, the first assembly part 31 can also be other connecting locks 25 that can be used to fix the central control box 30 on the corner frame 20, and the second assembly part can also be a locking hole that cooperates with the connecting lock 25, and this application is not limited.

[0040] After adopting the above technical solution, since the central control box 30 is an indispensable electric control system of the curved screen, the electronic components in the system box have many legs and also include large-volume power supplies and other devices. Most curved screens usually make the central control box 30 and the corner frame 20 into an integrated structure, that is, the central control box 30 is attached to the back of the corner frame 20, and the display module 10 is installed on the front of the corner frame 20. However, this fixed installation method will cause a certain degree of inconvenience during maintenance. Therefore, the present application sets the central control box 30 separately from the corner frame 20, and then detachably installs it in the receiving space formed by the corner frame 20 through the cooperation of the second assembly part and the first assembly part 31, which not only saves a lot of installation costs, but also when the power supply fails, the maintenance personnel can directly disassemble the central control box 30 for maintenance without disassembling the entire corner frame 20 or the entire curved screen. This is not only simple to operate, but also convenient, saving a lot of operation time. In addition, the curved screen of the present application can also improve the intersection of two display screens at the corners, which usually have problems of unevenness and excessive gaps, avoid the generation of dark lines at the corners, and make the surface of the entire display screen more beautiful and the display effect better after assembly.

In addition, the corner frame 20 composed of a plurality of vertical side panels 22 and a plurality of horizontal side panels 21 can effectively reduce the overall weight of the corner frame 20 and the arc-shaped screen, and reduce the manufacturing cost, simplify the manufacturing process of the corner frame 20, improve the production efficiency of the corner frame 20, reduce the cost, and greatly facilitate the transportation of the corner frame 20 and the splicing of the arc-shaped screen.

The plurality of internal plates 23 are spaced apart between the first horizontal side panel 211 and the second horizontal side panel 212 and extend in the horizontal direction, which can not only enhance the strength of the corner frame 20; at the same time, it can also disperse the force generated by the central control box 30 and the display module 10 to various positions of the corner frame 20.

[0044] During production, the vertical side panels 22 and the horizontal side panels 21 can be formed from the raw materials through simple cutting or stamping operations, and then the corner frame 20 for installing the central control box 30 and the display module 10 can be easily formed by splicing and fixing the vertical side panels 22 and the horizontal side panels 21. The production process is simple and efficient, which optimizes the production process to a certain extent and effectively reduces the production cost.

[0045] In addition, a center plate 24 that matches the size of the vertical side plates 22 is fixedly installed between the two horizontal side plates 21, and a plurality of inner connecting plates that match the size of the horizontal side plates 21 are arranged on the center plate 24 in sequence from top to bottom.

The flexible bottom shell can be made of a flexible material such as rubber or silicone, and the light board and the flexible bottom shell are connected by gluing, so the assembly is fast and convenient, which can well reduce the labor cost.

[0051] After adopting the above technical solution, since the flexible bottom shell is made of flexible material, it can be freely formed at any angle so that it can be fitted on the outer end surface of the corner frame 20, thereby achieving a display effect with an arc that matches the corner frame 20. It not only has good flatness, but also has a smaller thickness, is lighter, thinner, more beautiful, and easier to bend.
