ODA technology from Ledman powers Africa’s largest LED billboard.

In a landmark project for the digital out-of-home (DOOH) advertising industry in Africa, two mega digital billboards with a combined area of 944 m² have been unveiled along the N1 highway in South Africa.

These iconic structures, now the largest LED advertising screens on the continent, are powered by Ledman N-Series outdoor LED displays featuring the proprietary ODA (Optical Doward Angle) technology.

The project, delivered by Ledman’s outstanding partner Viron Group in collaboration with NAD Properties and RL Media, represents a significant step forward in visual communication and outdoor advertising infrastructure.

Superior technology for extreme demands

Selected for its exceptional performance and reliability, the Ledman N10 model, with a 10 mm pixel pitch, was deployed across the entire display surface. The choice was driven by the need for a solution capable of withstanding South Africa’s intense sunlight and variable outdoor conditions, while still delivering outstanding visual clarity.

The key to meeting these challenges is Ledman’s patented ODA technology. This innovative chip packaging process enhances brightness uniformity, colour fidelity and overall module robustness, laying the foundation for the display’s exceptional performance:

• Ultra-high brightness of 11,000 nits: guarantees perfect visibility and vivid imagery even under direct, intense sunlight.
• High refresh rate of 7,680 Hz: ensures flicker-free viewing and camera-ready performance, eliminating scan lines during video or photo capture.
• Robust and weatherproof design: engineered to withstand harsh environmental conditions, ensuring long-term durability and minimal maintenance.
• Energy-efficient operation: delivers high luminous efficacy, providing brilliant visuals while optimizing power consumption for sustainable operation.

A collaborative milestone

This achievement highlights the value of strategic partnerships.

We are delighted to see our ODA-powered N-Series displays at the heart of this transformative project. Working with expert partners like Viron Group allows us to push the boundaries of what is possible in large-format outdoor advertising, said a Ledman spokesperson.

The successful implementation demonstrates Ledman’s ability to deliver customized, high-performance solutions for flagship projects worldwide. It also sets a new technological standard for the DOOH market in Africa, showing how advanced digital displays can become reliable and impactful landmarks.
