[0002] The immersive LED display screen is often used in exhibition halls, exhibition halls, cultural tourism, science and technology museums, experience museums and the like, and the type of application is mostly used for displaying local tourism culture, knowledge transmission and actually experiencing local characteristics. In addition to the surrounding vision, the interactive effect of this type of project is composed in various forms: radar, gravity, infrared and body interaction.

[0003] Some technical solutions about display screen splicing devices have appeared in the prior art, such as a Chinese patent with application number 2021103848008, which discloses a transition device for a polyhedral LED screen splicing place and a VR immersive hexahedral display screen, comprising a point transition assembly and a line transition assembly. The point transition assembly is a spherical inwardly curved arc structure for displaying pictures, and the point transition assembly is connected to one end of the line transition assembly. The line transition assembly is a long strip-shaped inwardly curved arc structure for displaying pictures, and the line transition assembly is connected to the planar LED box assembly.
