Hey everyone!
I plan to post a bunch of details here about the process we went through but we recently completed the creation of an LED Video Wall that is built in 50 panels. Each panel is 4' x 4' and has 400 LEDs on it. We have a teensy board every 2 panels. We have managed to push the wall to 48fps and maintain stability. The major limiting factor is getting all the data out over serial. Even with multithreading it is hard to get it out in time. We also did some complex color correction on the LEDs by imaging all the LED panels with a dSLR and calculating the luminance of each RGB sub-pixel so that they are consistent.
Our code is written so it captures a region of the screen then feeds that to the video wall. Attached below is a latest videos we made of the James Bond intro sequence and a mashup music video. If you have any questions on the project (i.e. how did you get X working feel free to contact me)
