Product Description

Ultra Bright 1.8mm 16x16 COB LED Matrix for Displays
Product Overview
    Introducing the Ultra Bright 1.8mm 16×16 COB LED Dot Matrix Display-a high-resolution, cost-effective solution engineered for moving signs, digital display screens, and dynamic information boards. Designed to prioritize ultra-fine dot pitch, uniform brightness, and seamless (tiling) for large-scale displays, this COB dot matrix excels at showing scrolling text, dynamic icons, or simple animations.
    Its 1.8mm dot diameter and 16×16 pixel resolution deliver, high-definition visuals-ideal for close-range viewing (1-3 meters) in retail, office, or public spaces. The 40×40×3.5mm ultra-thin COB design reduces installation depth, while the big dual-axis viewing angle ensures readability from all positions. With low power consumption, stable performance, and RoHS compliance, this display is optimized for 24/7 operation in moving signs and tiled display screens.
Backed by a daily production capacity of 10,000 pieces and flexible logistics options, it meets high-volume order demands for commercial signage projects.

Key Features (Moving Sign/Display Screen-Optimized)
1. COB Technology & Ultra-Fine Dot Pitch
1.8mm Emitting Dot Diameter: Ultra-small dot pitch ensures high pixel density (16×16 resolution) - no visible gaps between dots, delivering smooth scrolling text and clear dynamic visuals. Critical for moving signs where text/icon clarity directly impacts audience engagement (e.g., retail promotions, airport announcements).
COB (Chip-on-Board) Integration: LED chips are directly mounted on the PCB, eliminating traditional lead frames-enhances thermal conductivity (reduces overheating in 24/7 operation) and ensures uniform brightness across all 256 dots (no "dead dots" or brightness variation).
Ultra-Thin 3.5mm Profile: 40×40×3.5mm compact dimensions enable slim moving sign designs (e.g., wall-mounted thin displays, hanging signage) and easy tiling for large-scale screens (e.g., 4×4 unit for 64×64 resolution).
2. High Performance for Dynamic Displays
Ultra Bright & Uniform Illumination: COB technology delivers high luminous efficiency, ensuring visibility in bright ambient light and dim environments. Continuous uniform characters avoid blurring during scrolling-critical for moving signs where text moves at varying speeds.
Big Dual-Axis Viewing Angle: Wide horizontal and vertical viewing angles (typical ≥120°) ensure readability from off-center positions-no color shift or brightness loss.
Low Power Consumption (Extremely Low Current): Optimized for 24/7 moving sign operation-minimizes electricity costs for large-scale tiled displays and extends lifespan by reducing heat generation.
3. Durability & Easy Deployment
Stable Performance in Commercial Environments: Withstands temperature fluctuations and minor vibrations-no dot failure or scrolling glitches.
Long Lifetime: COB's robust construction and high-quality LED chips match the 5-8 year service life of commercial moving signs-eliminates frequent replacements, reducing maintenance costs for businesses.
Easy Assembly & Tiling: Standardized PCB design supports direct mounting and seamless (tiling) via pin headers or flexible cables-enables quick setup of custom-sized display screens.
4. Cost-Effective & Compliant for Commercial Use
Low Cost: COB manufacturing reduces component count and assembly time, offering a cost-competitive solution for high-volume moving sign projects.
RoHS Compliant: Free from lead, mercury, and harmful substances-safe for public spaces, meeting commercial signage safety standards.
High Production Capacity: 10,000 pieces/day output ensures timely delivery for large-scale projects.
5. Moving Sign-Specific Functionality
Fast Response Time: Supports smooth scrolling (up to 30fps) and dynamic animations-no lag or ghosting when text/icons move, ensuring clear readability even at high scrolling speeds.
Wide Voltage Compatibility: Works with standard moving sign power supplies (5V/12V) and driver ICs (e.g., MAX7219, HT1632C)-simplifies circuit design for signage manufacturers and integrates seamlessly with scrolling firmware.
