Exterior Plus (Aena) – Madrid – Barajas T4

TRISON deployed a large-scale airport digital signage network at Madrid–Barajas T4, integrating LED installations and distributed displays across the full passenger journey.

The Challenge

Madrid–Barajas T4 demands airport digital signage solutions that perform at scale. Exterior Plus required a high-impact communication infrastructure across boarding walkways, arrivals halls and transit corridors. However, each zone presented distinct structural constraints — including glass flooring and fire-safety requirements — that ruled out conventional installation approaches.

The Insight

TRISON developed a zone-by-zone engineering strategy. Large-format LED installations deliver maximum visual impact in the terminal’s highest-traffic areas. Meanwhile, a distributed network of digital displays ensures consistent coverage along passenger routes. Consequently, each solution was designed around the specific architectural and operational conditions of its zone — not applied as a standard rollout.

Immersive Scale

Four synchronised LED screens create a continuous visual environment across T4’s boarding walkways — engineered around the terminal’s glass flooring.

Boarding walkways: full-length LED environments

Four lateral LED screens — each measuring 16,128 mm × 2,880 mm — line the boarding corridors of Madrid–Barajas T4. The installation delivers synchronised content at a resolution of 3,888 × 2,952 pixels, exceeding 4K equivalent density across the full surface. The glass flooring made conventional anchoring impossible. Therefore, TRISON fixed the systems exclusively at their ends — ensuring full structural stability without any intervention to the existing floor.

Flexible content across the full corridor

Each walkway installation supports synchronised, independent and continuous playback configurations. Exterior Plus can therefore run a single brand campaign wall-to-wall or, specifically, segment the surface for multiple advertisers simultaneously. Additionally, content adapts in real time to passenger flow and campaign schedules — making the walkway system one of the most commercially flexible formats in the terminal.

From boarding to arrivals, the Barajas T4 installation delivers uninterrupted visual impact across the terminal’s most critical passenger zones.

Arrivals hall: airport digital signage at scale

Two horizontal LED screens — each measuring 16,128 mm × 3,168 mm — are installed at approximately four metres height, delivering over 102 m² of digital surface. A glass corridor behind the screens required H120 fire-resistant structures, ensuring full compliance with airport safety regulations. Additionally, each screen operates independently or in sync, allowing Exterior Plus to run coordinated campaigns or segment content for different advertisers simultaneously.

Completing the passenger journey with digital signage

Beyond the large-format LED zones, a distributed network of vertical and horizontal digital displays extends communication coverage across departure gates and transit corridors. Furthermore, each unit connects to power and data networks and operates continuously, forming a cohesive digital layer across T4’s highest-footfall areas. As a result, the deployment closes the full communication loop — from the moment passengers enter the terminal to the moment they board.
