Atlanta-based LED manufacturer NanoLumens has added infra-red edge sensors to make its narrow pixel pitch LED walls interactive, if needed.

“It used to be extremely difficult to add interactive elements to LED displays, but recent technological breakthroughs have made it much more feasible, practical, and affordable,” says NanoLumens CEO Rick Cope. “Our touch technology is fully integrated onto the display itself and gives our customers the true touch experience they are looking for. ”

It’s possible to do touch on an LED with a glass or a hardened plastic overlay, but that comes with baggage (like trapping heat and making servicing a much bigger deal).

How it’s done.
