KAILITE KH Series P3.9 Indoor 2x2m Foldable LED Poster Screen 512x512 Pixels 8 Unit Cascade Large Venue Display

The KAILITE KH Series P3.9 multi-fold LED advertising machine carries a 512 x 512 pixel resolution and the widest cascade tolerance in the KH family, supporting up to eight screens on one controller. SMD2121 lamp beads at 1/16 scan keep the display bright and stable across large viewing distances, which suits arena entrances, transport hubs and covered outdoor walkways where the audience stands several meters away. The 2000 x 2000mm face is spliced from four 1000 x 500mm and eight 500 x 500mm cabinets on a wheeled base, and the 33mm cabinet profile keeps the folded package slim for storage.

Up to eight screens can be driven as one canvas for arena and transport hub walls.

SMD2121 lamp beads deliver stable brightness across long viewing distances.
