Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where, when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0042] Referring to Figure 1 , Figure 4 and Figure 5 , a display screen includes a frame and a display module, the display module is installed on the frame. The frame includes a frame body 11 and a push-out mechanism, the push-out mechanism is installed on the frame. Specifically, the push-out structure includes a push-out assembly 10, the push-out assembly 10 includes a first element 1 and a second element 2, the first element 1 is provided with a slide 101, the slide 101 has a first position 102 and a second position 103 (see Figure 5 ) different from the first position 102 in the length direction, the first position 102 is closer to the display module than the second position 103. The second element 2 has a first connecting end 201, the first connecting end 201 is arranged in the slide 101, and the first connecting end 201 can slide in the slide 101 to realize the conversion of the first connecting end 201 between the first position 102 and the second position 103 by moving the first element 1; the frame body 11 is provided with a first mounting hole 111, the second element 2 passes through the first mounting hole 111 and is connected with the display module. When the first connecting end 201 is located at the first position 102, the second element 2 can push the display module away from the frame body 11. The movement of the first element 1 can be that the first element 1 slides relative to the frame body 11, and the slide 101 is inclined upward or inclined downward; the movement of the first element 1 can also be that the first element 1 rotates relative to the frame body 11, and the slide 101 is arc-shaped. By moving the first element 1, the second element 2 can push the display module away from the frame body 11, which is simple and convenient to operate.

[0043] Referring to Figure 4 and Figure 5In some embodiments, the pushing mechanism further includes a first operating member 3, which is connected to the first element 1. Operating the first operating member 3 allows the first element 1 to move. In some embodiments, the first operating member 3 is fixedly connected to the first element 1. Specifically, the first element 1 has a second connecting hole 104 and a third connecting hole 105, and the first operating member 3 has a second connecting post 301 and a third connecting post 302. The second connecting post 301 cooperates with the second connecting hole 104, and the third connecting post 302 cooperates with the third connecting hole 105, thereby achieving a fixed connection between the first operating member 3 and the first element 1. The first element 1 also has a rotating hole 107, which is connected to the frame body 11 via a rotating shaft. Pushing or pulling the first operating member 3 causes the first element 1 to rotate around the rotating shaft, thereby achieving the switching of the first connecting end 201 between the first position 102 and the second position 103. In some embodiments, the first element 1 is circular. The rotating hole 107 is located at the center of the first element 1. In some embodiments, the first operating member 3 and the slide rail 101 are located on opposite sides of the rotation center of the first element 1 (rotation center: i.e., the center of the rotation hole 107). When the first operating member 3 is perpendicular to the display module, the first connecting end 201 is located at the first position 102; when the first operating member 3 is parallel to the display module, the first connecting end 201 is located at the second position 103. When it is not necessary to push out the display module, the first operating member 3 is parallel to the display module, which is not obstructive and can prevent accidental touches.

[0044] See Figure 4 and Figure 5 In some embodiments, the first operating member 3 is provided with the ejection component 10 at both ends, that is, operating the first operating member 3 can simultaneously drive the two ejection components 10 to move.

When the first operating member 3 drives the first element 1 to move, the third element 4 drives another pushing-out assembly 10 not connected with the first operating member 3 to move. The third element 4 is two, so as to realize the connection of four pushing-out assemblies 10, so that when the first operating member 3 is operated, the movement of four pushing-out assemblies 10 can be realized, so as to realize the pushing of four corners of the display module. The first element 1 and the third element 4 are connected in the following manner: the first element 1 is provided with a first connecting column 106, and the end of the third element 4 is provided with a first connecting hole 401, the first connecting column 106 is matched with the first connecting hole 401 to realize the connection of the first element 1 and the third element 4, and the first connecting column 106 can rotate relative to the first connecting hole 401, so that when the first operating member 3 pushes the first element 1 to rotate, the third element 4 pushes another pushing-out assembly 10 to rotate.
