• LED (Light Emitting Diode) Displays: Increasingly used for robust, high-contrast content delivery. While traditional outdoor-grade high-brightness LEDs are too bulky, fine-pitch indoor LED panels provide excellent viewing angles and durability.
• OLED (Organic LED): Though costlier, OLED displays provide superior contrast and wider viewing angles, advantageous for smaller elevator cabins.

The display hardware often incorporates toughened, anti-scratch glass or acrylic overlays to withstand physical impacts within the cabin. Screen sizes are optimized to avoid claustrophobic sensations while maintaining readability.

System Components and Architecture

An elevator digital signage system typically consists of:

• Display Unit: Mounted internally within the elevator car, usually on a wall or ceiling panel.
• Media Player: Embedded or external device running digital signage software to manage content playlists, schedules, and network communications.
• Content Management System (CMS): Cloud-based or local software platform enabling content creation, upload, scheduling, and analytics. Leading CMS providers offer integration with building management systems (BMS) and third-party data sources.
• Connectivity: Wired Ethernet is preferred for reliability; however, Wi-Fi, 4G/5G cellular, or Power over Ethernet (PoE) solutions are also employed depending on infrastructure.
• Power Supply and Safety Compliance: Integrations must conform to local electrical codes and elevator safety standards, with battery backup options to handle power outages.

Standards and Regulatory Compliance

Elevator digital signage systems must comply with several industry standards to ensure safety and operational reliability, including:

• IEC 61508 & EN 50126/8/9: Functional safety standards relevant to elevator control systems where digital signage integration should not interfere.
• UL 60950 / IEC 62368-1: Safety standards for IT and electronic equipment.
• ADA (Americans with Disabilities Act): Ensuring displays do not obstruct access and are usable by people with disabilities.
• Fire & Electrical Codes: Compliance with NFPA, NEC (National Electrical Code), and local fire safety codes essential for electrical installations within elevator shafts and cabins.
• Privacy and Data Protection Regulations: GDPR and CCPA considerations if the system collects user data (e.g., via cameras or sensors).

Applications of Elevator Digital Signage Systems

Building Communication and Branding

Elevator digital signage is an effective medium for internal building communications, providing updates on:

• Maintenance activities, elevator schedules, and emergency notifications.
• Corporate news, event announcements, and wayfinding information.
• Brand storytelling, tenant promotions, and corporate social responsibility campaigns.

For commercial office buildings, this builds occupant engagement and enhances tenant satisfaction.

Advertising and Revenue Generation

Elevators are considered highly effective advertising environments due to the captive and often captive attention of passengers during wait and transit times. According to Nielsen research, elevator rides typically last 20–60 seconds, a sufficient window for impactful messaging.

Advertising networks specializing in elevator digital signage monetize this by renting screen time to local brands, retail outlets, or services, generating additional revenue streams for building owners. Content can be localized and contextual, tailored to the demographic and time of day.
