Ultra White 5 x 7 dot matrix led display 3mm Row Cathode for Elevator Position indicator
Product Overview
This 3mm dot diameter 5×7 dot matrix LED display is a position indicator-optimized solution, engineered exclusively for elevator floor number readouts, as well as home appliance and instrument panel status displays. Featuring a high-contrast white-dot-on-black-surface design, column anode/row cathode connection mode, and ultra bright white illumination, it delivers crisp, eye-catching single-character display (numbers 0–9, letters A–Z, symbols) even in dim elevator shafts or bright lobby environments.
With its compact 22.85×31.99×8mm footprint, the display fits seamlessly into elevator control panel PCB layouts. Its low-power consumption, extremely low-current operation, and long lifetime make it ideal for 24/7 continuous use in high-traffic elevator systems. Multi-color emission options and RoHS compliance further support global deployment, while IC compatibility and easy assembly streamline mass production for elevator and home appliance manufacturers.

Key Features (Elevator Position Indicator-Optimized)
1. Elevator-Scenario High-Visibility Readability
Ultra Bright White Dots + Black Surface Contrast: Eliminates ambient light glare from elevator lobby lights and shaft lighting, ensuring floor numbers are crisply readable from 1–3 meters—critical for passengers rushing to board elevators or waiting in lobbies.
3mm Dot Diameter & 5×7 Matrix Layout: Supports clear single-character display of numbers, letters, and symbols (e.g., "F" for floor, "B" for basement), perfectly suited for elevator position indicators that require concise, intuitive readouts.
Big Viewing Angle (≥120° H/V): Delivers uniform visibility from vertical and horizontal oblique positions—passengers can read floor numbers whether standing in the center of the elevator car or leaning against the door.
2. Industrial-Grade Durability for 24/7 Elevator Operation
Extremely Low-Current Operation: Minimizes energy consumption for elevator indicator systems that run continuously, reducing building energy costs and aligning with green building standards.
Stable Performance in Variable Environments: Withstands temperature fluctuations (-10°C to 60°C) and minor vibrations from elevator car movement, ensuring no dot flicker or segment failure in long-term operation. Good batch consistency also ensures uniform brightness across all floor indicators in a building, enhancing brand image.
Long Lifetime (50,000+ Hours): High-quality LED chips match the 15–20 year service life of elevator systems, eliminating frequent display replacements and reducing maintenance costs for property management.
3. Manufacturer-Friendly Easy Integration
Column Anode/Row Cathode IC Compatibility: Works seamlessly with mainstream dot matrix driver ICs and elevator control microcontrollers. Simplifies circuit design for floor number switching, direction indication, and fault code display.
Compact Size & Easy Assembly: The 22.85×31.99×8mm slim profile fits into narrow elevator control panel PCB layouts. Standardized through-hole or SMT pinout design supports automated production lines, reducing assembly time and labor costs for elevator manufacturers.
Multi-Color Versatility for Functional Coding: Optional emitting colors enable targeted use in elevator systems:
Red: High-visibility for basement floor indicators
Green: Normal floor number display for passenger comfort
Blue: Modern aesthetics for premium commercial building elevators
