High brightness outdoor screen solution with 3.91mm pixel pitch

This LED module excels in adaptability and reliability, supporting multiple control methods for flexible integration with diverse systems. Equipped with high-quality driver ICs, it guarantees stable performance, enhanced color gradation, and reduced power consumption. The high brightness (up to 8000 nits or higher) ensures visibility even under direct sunlight, while a wide 160°+ viewing angle maximizes audience reach.

The use of premium PCB board and driver ICs guarantees vibrant colors, energy efficiency, and long-term reliability. With its high pixel density, this module is perfect for creating seamless, large-scale displays that captivate audiences. It delivers exceptional quality and performance, meeting the demands of modern outdoor display applications.

Dual service design LED module

The main feature of the front-rear service is its dual-access design, which allows technicians to perform maintenance and repairs from both the front and the back of the module. This design significantly enhances serviceability, especially in installations where access is restricted, such as facade-mounted displays or outdoor buildings with limited clearance.

Reduced Downtime: Quick repairs from either side minimize disruptions to display operations.
Lower Maintenance Costs: Simplified access reduces labor and time required for repairs.
Flexibility in Installation: Ideal for confined spaces where rear access may be limited.
Enhanced Reliability: Ensures continuous operation by making maintenance faster and more
