[0002] With the rapid development of LED display technology, the application scenarios of LED displays have expanded from traditional flat displays to diverse forms such as curved screens. Among them, spherical screens, due to their unique visual effects and immersive experience, are widely used in stage performances, exhibitions, planetariums, and other fields. Existing spherical screens consist of a support frame and display components. To facilitate the installation and maintenance of the display components, the support frame is usually designed with a door frame structure, allowing installers to enter the sphere through the door frame structure to assemble and maintain the display components. However, in practical applications, due to the weight of the display components and uneven stress during installation, the door frame structure is prone to deformation, thus affecting the stable installation of the display components.
