Perimeter LED displays are specialized screen systems installed around the edges of sports fields, arenas, or event venues, designed to enhance fan engagement and deliver dynamic content during games or performances. These displays typically feature P4-P8 pixel pitches, balancing resolution with viewing distance for spectators seated at varying ranges. High brightness (3000-5000 nits) and wide viewing angles (140°+ horizontally) ensure visibility from all seats, while high refresh rate drivers (1920Hz+) eliminate flicker for broadcast cameras. Rugged construction with IP54 ratings protects against dust and splashes, suitable for outdoor sports environments. Key functionalities include real-time game data visualization, sponsor advertisements, replays, and interactive fan polls. Modular designs allow quick installation and dismantling for temporary events, while custom curved configurations can follow the shape of the venue perimeter for seamless visual integration.
