Short definition
An LED wall is a modular display technology made of self-illuminating LED modules that can be assembled into almost any size surface. It's known for high brightness, wide viewing angles, and flexible shaping.
Detailed explanation
Unlike traditional projection, an LED wall generates its image directly through light-emitting diodes — no projection distance or screen required. Individual panels typically measure 500 × 500 mm or 500 × 1000 mm and can be combined into nearly any shape. Pixel pitch is key to image quality: 1.5–2.9 mm suits close indoor viewing, while 3.9 mm and above works better for larger viewing distances of roughly four to six meters.
With brightness levels from 800 to over 6,000 nits, LED walls perform well even in brightly lit halls or outdoors — conditions where standard projectors struggle. High contrast, viewing angles beyond 170°, and the option for curved or multi-part surfaces round out the picture. LED walls are driven by a video controller with sending and receiving cards; complex setups add a media server to manage content.
Relevance in this field
LED walls are the visually dominant element of modern events and have replaced traditional projection in many applications. They enable creative stage concepts that were previously technically impossible.
Practical example
For a concert, a curved, L-shaped LED wall measuring 14 × 5 meters is built. A 3.9 mm pixel pitch matches the minimum viewing distance of 5 meters. A media server plays the show content and lets the VJ make live adjustments on the fly.
