In a landmark project for the Out-of-Home (DOOH) advertising industry in Africa, two mega digital billboards with a combined area of 944㎡ have been unveiled along the N1 highway in South Africa. These iconic structures, now the continent’s largest LED advertising screens, are powered by Ledman’s cutting-edge N-Series outdoor LED displays, featuring the proprietary ODA (Optical Direct Assembly) chip technology.
The project, delivered by Ledman’s outstanding partner Viron Group in collaboration with NAD Properties and RL Media, represents a significant leap forward in visual communication and public advertising infrastructure.
Superior Technology Meets Extreme Demands
Chosen for its exceptional performance and reliability, the Ledman N10 model—with a 10mm pixel pitch—was deployed across the vast display surfaces. The decision was driven by the need for a solution that could withstand South Africa’s intense sunlight and variable outdoor conditions while delivering stunning visual clarity.
Key to meeting these challenges is Ledman’s patented ODA technology. This innovative chip packaging process enhances brightness uniformity, color fidelity, and overall module robustness, forming the foundation for the display’s outstanding specifications:
-Ultra-High Brightness of 11,000 nits: Guarantees perfect visibility and vivid imagery even under direct, full sunlight.
-High Refresh Rate of 7,680Hz: Ensures flicker-free viewing and delivers camera-ready performance, eliminating scan lines during video or photo capture for seamless media coverage.
-Robust & Weatherproof Design: Engineered to endure harsh environmental conditions, ensuring long-term durability and minimal maintenance.
-Energy-Efficient Operation: Achieves high luminous efficacy, providing brilliant visuals while optimizing power consumption for sustainable operation.
A Collaborative Milestone
This achievement underscores the power of strategic partnership. “We are thrilled to see our ODA-powered N-Series displays at the heart of this transformative project,” said a spokesperson for Ledman. “Collaborating with expert partners like Viron Group allows us to push the boundaries of what’s possible in large-format outdoor advertising.”
The successful deployment highlights Ledman’s capability to deliver tailor-made, high-performance solutions for flagship projects worldwide. It also sets a new technological standard for the DOOH market in Africa, demonstrating how advanced digital displays can become reliable and impactful landmarks.
