In the heart of Brussels, a city known for its vibrant urban life and strategic European relevance, a new DOOH landmark has taken shape: a monumental LED screen installed directly on the façade of an urban building. In a market where visibility, impact and reliability define the success of an advertising asset, this installation stands out as a powerful media platform, designed to captivate, inform and dominate the visual skyline.
DOOH Landmark in Brussels
With an impressive 12 × 7.2 m display area, 10 mm pixel pitch, and 6,000 nit brightness, the LED screen is engineered for maximum reach in one of the city’s high-traffic zones. Its scale alone transforms the location into a premium DOOH hub, while its technical performance ensures sharp, vibrant and consistent content throughout the day. This project demonstrates how large-format digital displays can reshape urban communication, turning architecture into media and visibility into tangible value.
Product used – SIGNUM-FS
For an installation of this magnitude, the choice of technology is crucial. The SIGNUM-FS LED platform by MacroPix was selected for its durability, thermal stability and outdoor performance, ensuring long-term reliability under varying environmental conditions.
Structural Strength, Reliability and Safety
Engineered to deliver resilience in the most demanding outdoor settings, SIGNUM-FS is built around a full die-cast aluminium architecture.
- Advanced Heat Dissipation
The LED board and modules are entirely made of die-cast aluminium, offering exceptional thermal conductivity and fast heat dissipation. A dedicated heat sink and cooling ribs on the rear side further stabilize temperature, while a ventilation gap between module and LED board improves airflow.
- Waterproof Design – IP68 / IP66
The front surface reaches IP68, the highest waterproof rating, allowing resistance even during prolonged exposure to heavy rain. The rear protection is IP66, with fully sealed module housing and waterproof connectors. A bottom drainage slot prevents fluid stagnation.
- Fire Resistance & Lightweight Build
The module’s construction meets 5VB fire resistance, while its aluminium frame keeps weight low at 24 kg/m² with a slim 75 mm thickness—ideal for façade-mounted installations.
Visual Performance and Image Quality
SIGNUM-FS is designed to remain perfectly visible in broad daylight, delivering strong image contrast and clarity even in difficult lighting conditions.
- Up to 10,000 nit Brightness
Far exceeding the standard SMD range, this extraordinary brightness ensures superior visibility under direct sunlight.
- High Contrast Ratio – 16,000:1
Deep blacks and vivid colors maintain crisp visuals at all times.
- 3840 Hz Refresh Rate
Smooth motion rendering, essential for video-heavy DOOH campaigns.
- Precision Brightness Control
The display supports 256 dimming levels without compromising image quality.
- Long-Term Luminance
Starting from 10,000 nit, the system maintains around 7,000 nit even after 5 years of operation. A mid-life recalibration can restore peak uniformity.
Technological Innovation & ROI Advantage
SIGNUM-FS integrates features designed to maximize energy efficiency, ease of maintenance and long-term economic value.
- CCES Energy-Saving Technology
Thanks to Common Cathode architecture and Ekoled “4-Leaf” technology, power consumption is reduced by 20% to 40%, significantly lowering operational costs.
- Cableless Connection
Power and data connections are hidden inside the lower frame. Module-to-module communication is handled via BTB connectors, improving reliability and eliminating visible cabling.
- Front and Rear Maintenance
Technicians can access components from either side using a dedicated unlocking key—no screws, magnets or complex disassembly required.
- Flexible Design Options
Modules can be cut at 45° or paired with curved sections, enabling L-shaped corners, curved screens or 3D anamorphic configurations.
- Future-Proof Architecture
LED boards with different pixel pitches can be fitted onto the same module structure, allowing seamless upgrades.
- Sustainable Build
The extensive use of die-cast aluminium ensures up to 90% recyclability, dramatically reducing plastic components.
Testing, Reliability and Certification
SIGNUM-FS meets the highest international standards.
- Certified by TÜV Rheinland (CE, EMC, LVD, ROHS)
Ensuring electrical safety, electromagnetic compatibility and restricted use of hazardous substances.
- HALT Stress Testing
Validated through Highly Accelerated Life Tests, including extreme thermal shock cycles from –40°C to +125°C, and vibration tests up to 45G.
These certifications make the SIGNUM-FS suitable for all long-term outdoor applications—stadiums, retail façades, rooftop screens, port areas, transportation hubs and premium DOOH sites.
Summary
The Brussels DOOH project introduces a massive 12 × 7.2 m LED display mounted directly on an urban building façade, designed to become a high-impact media asset within the city. Powered by the SIGNUM-FS technology, combining extreme durability, ultra-high brightness, energy efficiency and long-term reliability—the screen delivers sharp imagery, smooth video playback and continuous visibility in any light condition. A true next-generation DOOH installation, built to elevate the city’s visual landscape and maximize advertising performance.
