Digital signage is a system that uses digital displays—such as LCD, LED, OLED, or projection screens—to show multimedia content like advertisements, announcements, dashboards, menus, videos, or live information.

Typical digital signage systems include:

• Display screen – TV, commercial panel, LED wall, kiosk, etc.
• Media player – device that runs and displays content
• Content management software (CMS) – used to schedule and manage content remotely
• Network connection – LAN, Wi-Fi, or cloud connection for updates
• Content – images, videos, scrolling text, webpages, live feeds, etc.

Common uses

• Retail advertising
• Restaurant menu boards
• Corporate communications
• School and university notices
• Transport schedules
• Reception and lobby displays
• Smart city information boards
• Security/control room dashboards
