Shuifa Singyes Subway Multimedia System represents a revolutionary application in subway advertising. This system innovatively utilizes subway platform screens to achieve dual functionality: “safety assurance + advertising display.” When trains enter the station, the platform screens power up to remain transparent, ensuring train operations and passenger safety. After trains depart, the screens switch to projection mode to display advertising content. Shuifa Singyes New Materials holds independent intellectual property rights. Designed for metro environments, the system delivers stable, all-weather, long-term operation, overcoming the limitations of traditional subway advertising.
