An LED grid screen is a transparent display composed of LED (light-emitting diode) light beads, named for its grid-like (fence-like) structure. It creates a hollow design by arranging LED light strips or panels at regular intervals. This ensures high light transmittance and ventilation while maintaining visual quality. It is widely used in architectural curtain walls, stage backdrops, commercial advertising, and other fields.
Key Features
Transparency
The wide spacing between the light strips allows for an overall light transmittance of 30%-70%, minimizing the impact on building lighting or visual obstruction.
It is suitable for installation in glass curtain walls, stages, and other environments where both display and light transmission are important.
Lightweight Design
Using an aluminum profile or carbon fiber frame, it weighs significantly less than traditional LED screens (typically only 10-20 kg/m2), reducing the load on the building.
Energy-saving and environmentally friendly
The low power consumption design, combined with intelligent dimming technology, significantly reduces energy consumption.
Flexible Installation
It supports installation on curved and irregular surfaces, adapting to complex architectural structures.
The modular design allows for quick assembly and disassembly, as well as maintenance.
Technical Principle
LED Arrangement: LEDs are arranged in rows or columns on the PCB, forming a strip or grid structure.
Drive Method: Dynamic scanning is used, with the control system controlling the on/off of the LEDs to display images or videos.
Light Transmittance Control: By adjusting the spacing between the light strips and the density of the LEDs, a balance is achieved between display clarity and light transmittance.
Application Scenarios
1. Architectural Curtain Walls: Replace traditional glass curtain walls to enable dynamic advertising, information dissemination, or artistic displays.
Examples: Shopping mall exteriors, office building facades, and landmark light shows.
2. Stage Performances: Used as a backdrop or prop, combined with lighting effects to create an immersive experience.
Examples: Concerts, theaters, and large-scale event stages.
3. Commercial Advertising: Used for outdoor billboards and window displays to attract pedestrians' attention.
Examples: High-traffic areas such as pedestrian streets, subway stations, and airports.
4. Traffic Signs: Installed in tunnels, overpasses, and other locations to display traffic information or warning signs.
Differences from Traditional LED Screens
| Features | LED Grille Screen | Traditional LED Display |
| Light Transmittance | High (30%-70%) | Low (almost no light transmittance) |
| Weight | Light (10-20 kg/㎡) | Heavy (30-50 kg/㎡) |
| Mounting Methods | Hanging, clinging, curved surface mounting | Fixed bracket mounting |
| Applicable Applications | Curtain walls, stages, outdoor advertising | Indoor stages, conference rooms, stadiums |
Development Trends
High Definition: Fine-pitch LED grid screens (such as P3 and P4) are becoming increasingly popular, enhancing display detail.
Intelligent: Integrated sensors and AI algorithms enable features such as automatic brightness adjustment and content interactivity.
Flexibility: Developing flexible, bendable LED grid screens to accommodate a wider range of creative design needs.
LED grid screens, with their unique transparency and lightweight advantages, are becoming a new favorite in architectural media and commercial display, offering new possibilities for urban landscapes and creative displays.
