LED Wall
Also: video wall · dvLED
An LED wall is a direct-view display assembled from modular panels of LED pixels: each panel is its own light source, tiled into arbitrary sizes and shapes. Walls are specified by pixel pitch, panel dimensions, and brightness, and fed by an LED processor.
In practice
Direct emission is the advantage: LED walls overpower ambient light that washes projection out, run outdoors at noon, and build into shapes projection cannot. The signal chain is its own stack: content to media server to processor to receiving cards in the panels, with redundancy loops on serious shows.
The practical craft is mechanical as much as electronic: flown versus ground-supported structures, panel alignment (a bad seam reads forever), power and data looms per column, and spares math. Camera interaction (refresh rate, moire) is its own page; the flicker calculator covers the arithmetic.
How you’ll hear it
"Upstage wall is 14 by 8 panels of 2.9; processor takes program on fiber with a backup loop."
