Digital signage refers to electronic displays—such as LED screens, kiosks, or digital menu boards—that show multimedia content for communication, advertising, or information purposes. Unlike static printed signs, it provides real-time updates and interactive features. It exists because businesses, public institutions, and retailers need a dynamic way to reach audiences, convey messages swiftly, and adapt content to different contexts or times of day.

Challenges It Solves
Real-time communication: Announcements or promotions can be instantly updated.
Engagement: Interactive screens, voice, or smart sensors create immersive experiences.
Revenue generation: Ad monetization on public screens increases income.
Efficiency: Reduces reliance on printed materials and waste.
