Super Red 5 x 7 Square dot matrix led display Row cathode column anode For elevator position indicator
Product Overview
This 5×7 square dot matrix LED display from Light-Bo is a high-efficiency, elevator-optimized solution designed for clear, reliable floor number and direction indicator readouts. Engineered with a row cathode + column anode connection structure, 3.5mm white diffused epoxy dots on a black face, and super bright red light (620–625nm wavelength), it delivers exceptional contrast and visibility in both dim elevator shafts and brightly lit building lobbies.
With a compact 24×32×7mm footprint, it fits seamlessly into narrow elevator control panel PCB layouts, while its big vertical/horizontal viewing angle ensures floor numbers are readable from any position inside the cabin. Backed by a 20,000 pcs/day production capacity, 1000-piece MOQ, and rapid 5–7 day delivery, it meets the high-volume, time-sensitive needs of elevator equipment manufacturers. RoHS compliance and IC compatibility further streamline global deployment and system integration.

Key Features (Elevator Position Indicator-Optimized)
1. Elevator-Centric High-Contrast Visibility
Super Bright Red Illumination: The 620–625nm red light cuts through ambient light variations and ensures floor numbers are clearly visible at viewing distances of 2–5 meters—critical for passenger safety and convenience.
White Diffused Dots + Black Face Contrast: Eliminates "hot spots" and ensures uniform light distribution across all 35 dots, preventing digit distortion even during prolonged 24/7 operation. The high-contrast design also enhances readability for passengers with mild visual impairment.
Big Vertical/Horizontal Viewing Angle: Delivers clear visibility from any position inside the elevator cabin and from hallway call panel distances—no need for passengers to crowd around the display.
2. Industrial-Grade Durability & Stability
Elevator Environment Resilience: Withstands frequent vibration from elevator start/stop cycles, temperature fluctuations , and electromagnetic interference from elevator control systems. No flickering or dead dots during long-term use.
Excellent Batch Consistency: Strict production quality control ensures uniform brightness and color across all units—essential for elevator manufacturers requiring consistent appearance across entire building installations.
Long Lifetime: High-quality LED chips and robust epoxy construction match the 15–20 year service life of elevator systems, eliminating frequent display replacements and reducing maintenance costs for building management.
3. Manufacturer-Friendly Easy Integration & Cost Efficiency
Row Cathode + Column Anode Compatibility: Works seamlessly with mainstream dot matrix driver ICs and elevator control system microcontrollers. Simplifies circuit design for floor number display, up/down direction indication, and fault code alerts.
Low Development Cost: Plug-and-play compatibility with standard driver ICs reduces R&D time and costs—no need for specialized firmware development for basic elevator position indication functions.
Rapid Delivery & High Capacity: 20,000 pcs/day production output and 5–7 day delivery meet tight project timelines for large-scale elevator installations, while EXW trade terms offer flexible logistics options for global customers.
4. Energy Efficiency & Multi-Color Versatility
Low Power Consumption: 10–15mA recommended forward current minimizes energy use for elevator systems running 24/7, aligning with building energy-saving standards and reducing operational costs.
Multi-Color Customization: Optional emitting colors enable brand differentiation and functional coding for diverse elevator applications:
Pure Green: For "normal operation" status cues or residential building elevators
Blue: Modern aesthetics for premium commercial office tower elevators
Amber: Warm tones for hotel and hospitality industry elevators
