Seoul Subway Line 3 Gyodae Station MaxVision Digital Billboard

MaxVision is a large-format DOOH network installed across 24 high-traffic Seoul subway stations on Lines 1–4, positioned at high-visibility points such as concourse centers, fare gates, transfer corridors, and connecting stairways for seamless exposure along passenger flow. The oversized digital screens deliver strong visual impact, and select units support audio output for enhanced brand video content. The placement efficiently reaches a mass audience of commuters and daily travelers — predominantly in the 20–40 age bracket — with repeated exposure driven by extended dwell time across Seoul's key commercial districts.
