When setting up an LED display screen stage, technical aspects, safety, and visual effects must be considered comprehensively. The following are key points:
Core Setup Key Points
1. Structural Safety and Load-Bearing Design
LED display screens are heavy, and the stage must have sufficient load-bearing capacity.
Prioritize steel structures or high-strength aluminum alloy stage frames to ensure structural stability and prevent shaking, avoiding safety accidents caused by insufficient load-bearing capacity. 12
2. Scientific Site Selection and Viewing Angle Optimization
The screen should be placed in the optimal viewing area for the audience (usually the center of the stage or the back wall), ensuring clear viewing from all angles. Avoid direct strong light sources to prevent reflections or color distortion, and consider visual integration with stage scenery and props. 3
3. Professional Installation and Fine Tuning
• Installation should be carried out by a professional team to ensure tight module splicing and flatness, avoiding black lines or color differences.
• Adjust brightness, contrast, color temperature, and refresh rate to coordinate with the stage lighting. A high refresh rate (≥3840Hz) reduces flickering during filming and improves live/recorded broadcast effects. The screen content should be highly consistent with the performance theme and rhythm, avoiding excessive use of real-life videos (such as cityscapes, natural scenes) that can lead to visual confusion. Abstract graphics, dynamic lighting effects, or simple backgrounds are recommended to highlight the performers and prevent the screen from "stealing the show." 2
5. Lighting and Camera Coordination Design
LED screens emit strong light, which may interfere with traditional stage lighting effects.
Joint debugging of lighting and screen is required in the early stages to prevent the screen from being too bright, causing the actors' faces to be too dark, or resulting in blurry subjects and a lack of depth in television broadcasts. 2
6. Emergency Preparedness and On-Site Management
• The setup process involves tight deadlines and many personnel; therefore, reasonable division of labor is necessary, along with safety supervisors and standardized procedures for working at heights and electrical management.
• For outdoor events, prepare wind and rain protection measures, and check ground reinforcement and cable protection.
• During the event, assign dedicated personnel for inspections to ensure good heat dissipation and stable signals, and have backup playback equipment and power supplies. 1 2
7. Rental and Transportation Precautions (e.g., for rental screens)
• Confirm the screen's protection rating (IP65 or higher is suitable for outdoor use), and check the integrity of the modules. • Verify the compatibility of the control software and conduct signal source testing in advance.
• Clearly define responsibilities for disassembly and assembly, and establish terms for handling logistics risks.
