Light Emitting Diode (LED) technology is the backbone of modern electronic signs in elevators due to its high brightness, energy efficiency, longevity, and versatility. LEDs can be arranged in different configurations, such as 7-segment numeric displays, dot matrix displays, or full-color graphic panels, depending on the functionality required.

One major advantage of LED displays in elevator applications is their excellent sunlight readability and wide viewing angles, enabling passengers to clearly read information even in brightly lit or glare-prone environments. Industrial-grade LEDs designed for outdoor and high ambient light conditions can reach brightness levels exceeding 5,000 nits—a critical parameter to achieve sunlight readability as recommended in display technology references such as the International Electrotechnical Commission (IEC) standards.

Display Types and Configurations

• 7-Segment Numeric Displays: Commonly used for indicating floor numbers with LED digits. These are low-cost, simple, and reliable.
• Dot Matrix Displays: Allow for alphanumeric characters and simple graphics (e.g., arrows showing direction). They offer flexibility and can display messages or status updates.
• Full-Color LED Panels: Capable of showing complex information, entertainment content, advertisements, and emergency alerts in color, enhancing user engagement.
• OLED and LCD Panels: While less common in elevator signage due to limited sunlight readability and durability concerns compared with LEDs, OLED and LCD displays are sometimes integrated for advanced interactive systems.

Control Systems

Electronic elevator signs are connected to the elevator control system, which sends real-time information such as current floor, travel direction, overload warnings, and emergency messages. These data feeds ensure synchrony and functionality compliance. Advanced control units utilize protocols such as CAN bus or MODBUS over industrial-grade communication interfaces, enabling integration with building management systems (BMS) and Internet of Things (IoT) platforms for enhanced monitoring and diagnostics.

Practical Applications of Electronic Elevator Signs

Passenger Information Display

The primary role of elevator electronic signs is to inform passengers about elevator status, including the current and next floor, direction of travel (up or down), and door status. This real-time information reduces passenger anxiety and improves flow management, particularly in busy buildings.

Emergency and Safety Notifications

In emergencies such as fire alarms or power failures, electronic elevator signs display crucial safety instructions—whether indicating elevator recall status, advising passengers not to use the elevator, or providing evacuation guidelines. Compliance with regulations such as NFPA 101 (Life Safety Code) in the US and EN 81 standards in Europe often requires visible and clear communication through these signs.

Advertising and Communication

Some modern elevator signs integrate advertising or public communication content, turning elevators into strategic digital communication platforms. This dual function adds value to building owners and improves passenger experience, especially in commercial environments.

Accessibility Assistance

Electronic signs also play a vital role in accessibility, offering features like visual announcements for hearing-impaired users, integration with voice systems, and easy-to-read displays conforming to the Americans with Disabilities Act (ADA) or equivalent international standards.

Advantages of Using Advanced Electronic Signs in Elevators
