Types of Digital Signage
Digital signage is usually classified three ways. By environment: indoor (350 to 700 nits, the majority of screens), outdoor (2,500 nits or more, weather-rated) and semi-outdoor (drive-thru lanes, covered entrances). By interactivity: passive displays, interactive touch or gesture screens and kiosks, and triggered displays that react to sensors or data. By configuration: single displays, video walls, kiosks, menu boards, shelf-edge screens, LED billboards and transparent or projection displays. The most common type by far is the single indoor display with a small media player behind it: menu boards, lobby screens, promotional screens and dashboards.
Digital signage encompasses a vast array of display technologies, configurations, and applications. This comprehensive guide categorizes every type of digital signage to help you understand the options available for your specific needs.

Frequently asked questions
What are the main types of digital signage?
By environment: indoor, outdoor and semi-outdoor. By interactivity: passive, interactive (touch, gesture, mobile) and triggered (sensor or data driven). By configuration: standalone displays, video walls, kiosks, digital menu boards, shelf-edge displays, wayfinding directories, LED billboards and transparent or projection displays. Most deployments are single indoor displays running a cloud CMS.
What is the difference between indoor and outdoor digital signage?
Brightness and protection. Indoor displays run 350 to 700 nits and rely on room conditions; outdoor displays need 2,500 nits or more to beat sunlight, an IP-rated weatherproof enclosure, heating and cooling for temperature extremes and often a protective glass front. Outdoor hardware costs several times more per screen; the software and players are the same.
What is the most common type of digital signage?
A single indoor commercial display or TV with a small media player behind it, running a cloud CMS: menu boards in restaurants, welcome and promotional screens in lobbies and stores, announcement boards in schools and offices, and waiting-room screens in clinics. These make up the majority of screens installed and are the cheapest to run, from $0 to $30 per screen per month in software.
