LED displays have become the visual heartbeat of our built environment. From colossal outdoor billboards crowning city skylines to sleek, wall-flush lobby screens, from immersive retail façades to mission-critical control rooms, LEDs deliver brightness, color fidelity, and dynamic content with remarkable efficiency. Yet behind the pixels lies a decision that quietly shapes the entire lifecycle of your screen: how you will maintain it.
While specifications like pixel pitch, brightness, and refresh rate tend to dominate selection conversations, the maintenance method—front service or rear service—is just as crucial. It determines where you can physically install a screen, how fast you can resolve faults, how much structural space you must allocate, how your team will work safely, and ultimately, what your total cost of ownership (TCO) will be over years of operation.
Generally, when it comes to the maintenance of LED screens, there are two popular methods: front service and rear service.
