LED 101 / Basics
Wall size and resolution
Diagonal inches and pixel pitch together set native resolution. Cabinet size decides which wall sizes tile cleanly.
People shop LED walls by diagonal inches the way they shop TVs. The useful numbers are width, height, and pixel pitch. Native resolution is roughly width divided by pitch by height divided by pitch, in millimetres. A finer pitch at the same physical size means more pixels and usually more cost.
Cabinets tile into walls. If cabinets are 16:9, common finished walls stay 16:9 when you stack them in a grid. LUXVISION PROLUX Rugged cabinets, for example, are commonly 1280×720 mm or 1600×900 mm, building familiar diagonals such as 173″, 217″, 231″, and 289″. Fine-pitch COB cabinets are often smaller (for example 600×337.5 mm) and build different standard grids. Outdoor cabinets come in several footprints that mix only when row heights and column widths stay consistent.
Match pitch to viewing distance first; see Pixel pitch and Viewing distance. Overspecifying pitch on a gym wall wastes budget. Underspecifying pitch on a close lobby wall makes the image look chunky.
Controller port limits care about pixel count and how cabinets are wired on the map, not only the marketing diagonal. A wide outdoor ribbon can need more ports than a compact 16:9 gym wall with fewer total pixels. Your integrator should show the pixel math with the controller model. See Content and control.
