I have always felt sorry for any poor soul who gets the arm put on them to go to a trade show and get schooled up on digital signage - because there are so many hardware and software companies selling variations on what is essentially the same stuff.
I would really feel sorry for someone walking into a big display show, charged with finding the most suitable LED display technology for a project. There are 100s and 100s of options out there, and lots of terms being thrown around that seem to have different meanings.
There's chip on board. SMD. Mini-LED. Micro-LED. Glue on Board. 4 in 1 LED. On and on it goes. It's "My head's going to explode!" territory.
The LED video wall business is the sort of thing that begs independent, educated analysis, and happily, there are a few people out there doing that work. Like Eric Virey, a Frenchman who lives in Portland, Oregon, and spends his working life looking at and decoding the LED display business.
Virey, a Senior Technology & Market Analyst for the French market research company Yole Developpement, kindly gave me some of his time recently to help clear some of the fog. There was something up with his mike, so the sound quality is not as good as I'd like.
