In stage performances, relying solely on stage lighting for illumination is far from sufficient. It is necessary to use LCD screens to present video materials and images to the audience. This allows the entire stage to break away from a single, fixed perspective, creating an immersive visual impact as if the audience were in a real scene. It also better showcases the beauty of the stage and creates a magnificent visual effect. In stage scene layout, we can refer to the method of hoisting stage lighting with stage electric hoists to hoist LCD screens.
Compared with lighting equipment, LCD screens are more prone to breakage and have higher requirements for aesthetic presentation. Moreover, there are no firmly fixed hanging points above them, which invisibly increases the difficulty of hoisting LCD screens with stage electric hoists. In most performance venues, a hanging beam is installed at the top and a bottom beam at the bottom. The hanging beam is used to suspend stage electric hoists, and wire rope slings are equipped under the electric hoists to hoist the large screens. As the electric hoists move, the screen bodies can also move freely, and can even be moved apart or combined. After the performance, the LCD screens can be smoothly disassembled. At the performance site, we can take advantage of the numerical control electric hoists to control the stage lighting and LCD screens through a programming system.
