[0052] In an optional embodiment, the positioning member 21 has a toggle rod 212, and a sliding hole 11 is formed on the bottom shell 10. The toggle rod 212 is movably installed in the sliding hole 11 to drive the positioning member 21 to move along a preset direction of the bottom shell 10, so that the second positioning groove 211b and the first guide groove 2111 can be engaged in the guide groove 222.

[0053] like Figures 1 to 9As shown in the figure, according to the second aspect of the present application, the present application provides a display screen, including a box frame 200 and the above-mentioned display module 100. The bottom shell 10 of the display module 100 is connected to the box frame 200. An activity port 201 is provided on the box frame 200. A toggle rod 212 passes through the activity port 201 and is located outside the activity port 201, and is used to control the positioning member 21 to move along a preset direction of the bottom shell 10. Wherein, the preset direction is the splicing direction of the display module 100. For example, if the display module 100 is spliced along the width direction of the bottom shell 10, the preset direction is the width direction of the bottom shell 10; if the display module 100 is spliced along the length direction of the bottom shell 10, the preset direction is the length direction of the bottom shell 10.

[0054] In an optional embodiment, the display screen further includes a connection component 300. The connection component 300 includes a first component 301 and a second component 302. The box frame 200 has opposite first and second sides. The first component 301 is arranged on the first side, and the second component 302 is arranged on the second side. The first component 301 cooperates with the second component 302 to guide the splicing of the box frame 200 and play a positioning role, so as to shorten the alignment time, improve the assembly efficiency, and also reduce the gap between the box frames 200, reduce the possibility of bright and dark lines appearing between the gaps of the box frames 200, and improve the display effect.

[0055] In an optional embodiment, the first component 301 includes a first mounting seat 3011, a first pin 3012 and a dial rod 3013. The first mounting seat 3011 is mounted on the bottom shell 10. The first pin 3012 is movably mounted on the first mounting seat 3011. The dial rod 3013 is used to drive the first pin 3012 to be connected to the second component 302 of another box frame 200.

[0056] In an optional embodiment, the second component 302 includes a second mounting seat. The second mounting seat is provided with a pin hole 3021 and a limit hole 3022.

[0057] In an optional embodiment, the display screen further includes an elastic sheet 400. The elastic sheet 400 is arranged at the splicing position of two adjacent display modules 100, and is used to limit the flatness of the two adjacent display modules 100 after splicing, ensure that the two display modules 100 can be in the same plane after splicing, and further make the display surfaces of the display modules 100 in the same plane, ensuring the flatness of the display surface. Among them, because the elastic sheet 400 has a certain elasticity, when the display screen is spliced into an arc structure, the arc of the elastic sheet 400 plays a certain role in controlling the arc of the box frame 200, making the arc surface smoother.

[0058] Exemplarily, when the display screens are spliced into an arc screen, the elastic sheet 400 can limit the upper and lower display modules 100 to prevent the upper and lower display modules 100 from being uneven or even misaligned when the arc of the display screen is adjusted.

[0059] In addition, the elastic sheet 400 can also be used to block the light transmitted through the splicing seam to avoid the light affecting the display effect of the display screen. Among them, the elastic sheet 400 is fixed to the back of the display module 100 by a fixing member and is located at the splicing position of the two display modules 100. The two ends of the elastic sheet 400 are connected to the cabinet frame 200, which has a limiting function and can also block the light emitted from the gap between the splicing of the back of the display module 100, thereby avoiding affecting the display effect.
