How has the LED landscape evolved over the past ten years?
Perhaps most importantly, the industry has embraced a content first approach. LEDs are no longer just screens; they’ve become a medium in their own right, encouraging tailored content creation that complements the environment and application. This blend of affordability, flexibility and creative potential has made LEDs transformative across diverse sectors, from retail to film production to live entertainment.
What is one of your favourite LED products, and why?
For me, it’s not just about the LED panel but the entire ecosystem that surrounds it. The technical capabilities of a screen – such as black levels, colour depth and brightness – are undoubtedly important but equally critical are the systems driving the content. The performance of media players, including frame rates, compression handling and playback quality, can significantly influence the overall experience. Transparent LED is one innovation that stands out. This tech combines visual impact with subtlety, delivering striking visuals while blending seamlessly into the environment. Ideal applications include retail windows, allowing for engaging displays without obstructing the view of products; or car showrooms, enhancing the luxury feel without overpowering the vehicles on display.
How are vendors and customers improving when it comes to considering sustainability?
At the operational level, content adjustments – such as lowering unnecessary brightness levels – can further enhance efficiency. Modular designs are gaining popularity, as they allow for individual components to be upgraded or replaced rather than discarding the entire unit. This not only extends the product’s life cycle but also reduces electronic waste. The second-hand market for LED displays is thriving as well. Displays that are no longer suitable for high-profile applications are being refurbished and re-purposed for use in less-demanding environments, ensuring they continue to deliver value rather than being discarded or decommissioned prematurely. Additionally, there is a growing emphasis on tracking both operational and embodied carbon. Vendors and customers are collaborating to measure and mitigate emissions, making sure sustainability is not just a buzzword but a measurable outcome.
What are some of the challenges faced by this sector and how can we overcome them?
The flexibility of LEDs – capable of taking on virtually any shape or size – means bespoke content is often necessary. This complexity extends to pixel mapping, playback systems and media servers, all of which add layers of technicality that not every team is equipped to handle. Another challenge is maintaining consistency in colour and brightness across displays, particularly in large-scale installations. Even small variations can detract from the visual impact and require meticulous calibration. Educating users about the many nuances of LED technology and content management can empower them to maximise the potential of their systems.
Are there any future trends in LED that sound exciting to you?
Driven largely by innovations in integration and immersion, the future of the LED industry is brimming with potential. Technologies like transparent and flexible LEDs are paving the way for displays that can blend into their surroundings and take on entirely new forms, such as wrapping around objects or conforming to curved surfaces. We’re also seeing LEDs merge with other technologies for multi-sensory experiences. For example, combining LED displays with drones, projection mapping and interactivity allows for immersive and unprecedented audience engagement. These integrations are particularly exciting for live events and experiential marketing, where the goal is to captivate and amaze. Another key trend is the use of LED tech in architectural applications, such as wrapping skyscrapers in dynamic displays or integrating LEDs into interior designs. These applications demonstrate how LEDs can transcend their traditional role as screens to become integral elements of the built environment.
