Transit Hub Poster LED Screens: Delivering Real-Time Info & Elevating Travel Experiences

International airports primarily adopt poster-style LED displays, as they can provide multilingual information in real-time in high-traffic and variable-light environments, and technical reliability is an unnegotiable requirement. Traditional paper flight status indicators become outdated shortly after changes at the boarding gates or when flights are delayed for a few minutes, causing confusion among passengers. In contrast, airport-level poster-style LED displays combine high-performance visual effects with strong connectivity. Dubai International Airport's Terminal 3 (the world's busiest international terminal) installed 120 poster-style LED displays in 2024, ranging from 32-inch units at the boarding gates to 2-meter by 4-meter screens in the duty-free area. They feature a 2.0-millimeter pixel pitch (P2.0), 1000-nit brightness (with 100-level dimming function), and a 1920Hz refresh rate, ensuring smooth viewing even in sunlit waiting halls and dim boarding areas.
Through seamless integration with the airport's AODB (airport operation database) via REST API, flight status (colored coding: green for on-time, amber for delayed, red for cancelled) is refreshed every 15 seconds. They support content switching in 16 languages and have built-in redundancy: dual power supplies (100 - 240 volts AC and 24 volts DC backup) ensure normal operation during power fluctuations, and hot-swappable modules allow technicians to replace faulty panels without downtime. For duty-free retailers within the terminal, larger screens have 4K resolution and interactive touch points - passengers can scan QR codes to view product reviews or compare duty-free prices. Airport operation data shows that the number of inquiries at information desks has decreased by 47%, the error rate of boarding gate notifications has dropped by 22%, and duty-free sales have increased by 18% due to dynamic product promotions. These indicators highlight the value of these displays as both operational tools and revenue growth points in high-risk airport environments.
