In an LED video wall system, the Power Supply Unit (PSU)—specifically a Switched-Mode Power Supply (SMPS)—is the core component that regulates electricity. It converts high-voltage AC from the grid into the precise, low-voltage DC required by the LED modules and controllers.
Since LED walls are high-current devices, the power supply is often the most critical point for heat management and system stability.

In the context of LED video walls, the “outer profile” refers to the structural frame that houses the internal components (LED modules, Power Supply, and controllers). Unlike individual computer monitors, these profiles are designed for seamless tiling to create a single massive image.
The choice of outer profile determines the screen’s weight, installation speed, and overall durability.

A reliable LED Video Wall is built not only on high-quality display panels, but also on dependable accessories that ensure stable performance, safety, and long-term durability.
At ODLED, we supply a complete range of premium LED Video Wall accessories designed to support smooth installation, seamless operation, and consistent visual output.
