In my opinion, LED panels are lighting fixtures. Each fixture is comprised of lit pixels. Each pixel contains individual Red, Green, & Blue light sources. For example, if you are using a 3.9 mm panel, in a 500mm x 500mm configuration, each panel will contain, 16,384 pixels, producing light from a much smaller R, G, & B pixel to reproduce the video signal being sent to the processors. In essence, there are 49,152 light sources reproducing a video signal on a single 3.9mm LED panel.
As for a Video Tech, one uses an E2, S3, a Spyder, or a media server of some kind to send the video signal to an LED wall, confidence monitor, DSM’s, or projectors, etc… A Video Tech creates the pixel space parameters for content, to be displayed on the LED Wall and other video replication sources, based on the client’s needs.
I have great respect for Projectionists. I was actually going to become a Projectionist however, I found LED and never looked back. Projectionists use different technology, compared to LED Techs, to blend, converge, focus, adjust keystone, warp, etc… Especially when large format widescreens and multi-surface mapping are involved, which are VERY impressive. In my opinion, Projectionists are some of the most patient people in our industry that I have ever encountered. Props to Clem Harrod, Melvin LeGrand, John Smith, Joel Rodrigues, & Steve. Some of the coolest Cats I have ever worked with! Tex was awestruck when he visited the Grand Canyon.
