| Indoor LCD or LED-backlit LCD | Approximately 250–500 cd/m² | Offices, meeting rooms, classrooms, and indoor information displays | Clear images in controlled lighting; widely available in a range of sizes and resolutions | Strong ambient light or direct sunlight can make content harder to see. Confirm operating hours and warranty terms for commercial use. |
| Commercial high-brightness display | Often approximately 500–1,000 cd/m², depending on model | Bright retail areas, transit facilities, and spaces with substantial ambient light | Improved visibility in brighter indoor environments; commercial models may support extended operating schedules | Higher brightness can increase power use and heat. Match the specification to the actual light levels and viewing distance. |
| Outdoor digital signage display | Often approximately 1,500–3,000 cd/m² or higher | Outdoor advertising, storefronts, transport information, and exposed public areas | Designed for visibility in daylight; outdoor-rated units may include weather protection and temperature management | Check the specified ingress-protection rating, temperature range, sunlight readability, ventilation, and local installation requirements. |
| Interactive touchscreen display | Commonly approximately 300–500 cd/m² | Self-service kiosks, collaborative meeting rooms, wayfinding, and customer check-in | Enables direct user input and can combine instructions, forms, and interactive content on one screen | Choose a suitable touch technology and screen size. Plan for accessibility, cleaning, network security, and regular software updates. |
| Video wall | Varies by panel; commonly about 500–1,000 cd/m² for indoor installations | Control rooms, large venues, corporate lobbies, and high-impact retail presentations | Creates a large-format canvas from multiple panels and can show one image or several content zones | Consider bezel visibility, panel alignment, viewing distance, mounting structure, heat, and the processor needed to manage content. |
| OLED display | Varies by panel and content; check the manufacturer’s specifications | Premium retail presentations, reception areas, and spaces where deep blacks and contrast matter | High contrast and wide viewing angles; individual pixels can switch off to produce black | Assess brightness for the room, expected daily runtime, static-content exposure, and the manufacturer’s guidance on image retention. |
| E-paper display | Reflective technology; typically specified for ambient-light readability rather than backlight brightness | Price labels, schedules, room signs, and low-refresh information displays | Low energy use when content changes infrequently; remains readable in many well-lit settings | Refresh is generally slower than on video displays, and color, update speed, and low-light visibility depend on the specific device. |
