Quote:For those of you that do not speak LED sign speak, this is very good. Most businesses, churches, schools and other organisations tend to go with a 20mm pixel array. Most LED signs that you see on a daily basis are between 20mm & 16mm with 16mm considered as "high definition" from "viewing distance".


That they decided on 13mm is just showing off..... And I like it.


I think I read that the boards were being built by Daktroniks, they are the top brand in these type of signs. The only brand I sell to my customers anyway... Lol.

There is some good information in this Daktronics press release from March:

Also for you tekkies, here is more info on the pixel array (sorry for the formatting issues):

Which line spacing option is right for your location?
Line-and-column spacing is the distance between pixel centers on a display. Line spacing can also impact clarity and intensity at certain distances.
