The LED screen frame (also known as LED screen truss or support system) is an aluminum alloy modular support structure specially designed for events such as concerts, parties, and press conferences. Its main function is to securely and quickly fix large-area LED displays.
Main types and structures
1. Goal Post Truss
• Structure: Composed of two side columns and a top crossbeam in a "door" shape, combined with a base and diagonal braces.
• Feature:
☉ Hanging LED Screen frame: The screen is hung below the crossbeam, providing a clear view and no occupation of floor space.
☉ Integrated: It can be equipped with lighting and audio simultaneously, achieving "sound, light and electricity" integration.
☉ Quick Setup: Pin-type connection, suitable for tours and flash events.
• Applicable: Large concerts, outdoor and indoor large-scale performances, and scenarios requiring high-altitude suspension.
2. Ground Support
• Structure: Multiple layers of aluminum alloy square tubes / The frame is vertically stacked and horizontally connected, with diagonal braces added at the back.
• Feature:
☉ Directly against the wall / floor: The large screen is firmly attached to the stand, providing extremely strong stability.
☉ High flexibility: It can be used as a complete wall several meters high, or can be combined in sections.
☉ Ground load-bearing: It requires a high level of load-bearing capacity for the venue floor.
• Applications: Press conference backdrop wall, fixed stage, sports events, outdoor large screens.
3. Simple Support / Hand Crank Frame
Features: Lightweight, low cost, small screen area.
Applications: Small-scale events, weddings.
