Introduction
The LED Wall system is a core visualization component of the Mixed-Reality Lab. It provides a large (4.95m x 3.12m), high-brightness, 3D-capable display that enables immersive visual environments, virtual production workflows, and interactive experiences.
The system is designed to integrate with real-time rendering engines and other lab infrastructure, such as the tracking system. Depending on the experiment or demo, the LED wall can be used as a presentation display, a dynamic real-time surface, or an interactive visual element.
System Overview
The LED Wall system consists of a modular LED panel array (10x6) installed in the Main-Lab area, along with dedicated processor unit in the Sever room. Rendered content is generated on one or more render PCs and routed through the LED controller before being displayed on the wall.
The display supports 3D visualization using either:
Passive stereoscopic rendering with polarized glasses, or
Active stereoscopic rendering using shutter glasses
For passive stereoscopic output, two images are rendered (one per eye) and displayed in an pixel-wise interleaved manner.
The LED wall has a native resolution of 2560 × 1534 pixels and supports refresh rates of up to 240 Hz. It also supports displaying multiple independent content streams simultaneously using shutter glasses. Depending on the configuration, up to four separate content streams can be displayed in parallel, each at 60 Hz.
At a high level, the signal flow is:Render System → LED Controller → LED Panels
This modular design allows the LED-Wall to be used in different configurations depending on the requirements of the experiment or production. Multiple render PCs can be used to generate content, which is then composed and distributed by the controller. Panel layout and content mapping can be adjusted when required.
Typical Use Cases
Virtual production backgrounds for camera-based workflows
Immersive environments for example for mixed-reality and XR experiments
Interactive experiences driven by real-time rendering engines
Visualization of simulated or recorded data on a large, 3D-capable screen
Integration with motion capture systems for camera- or user-dependent visuals
Teaching and presentation scenarios requiring a large display
Limitations
- The LED-Wall can only be operated from the dedicated LED-Wall PC in the Server room, therefore a remote connection is preferred.
