Wow!
« on: January 05, 2016, »
I saw this in a mall. It's a Santa photo spot but the walls were made out of a led like surface. I wish we could move to this eventually.

This would be nice to have as certain elements to the show. I wouldn't want it as the whole thing.

I saw something like that in a mall too (actually looks like its the exact same unit).

I went and looked at it right up close, the walls are covered with are LED display panels. (looked to me like it was multiple smaller panels put together to make a large one for each wall)

Pretty cool stuff

If it really is LED, are they producing a brown color?

It was probably built from LCD panels.  They could be OLED panels but that is currently rather expensive.

@Steve Gase:
It was indeed animated, every so often 'pictures' would change, sometimes looking like a log cabin, sometimes more like a Victorian cottage. (they didn't just swap out, the change would start at the bottom and 'build' up the walls..someone really put some effort into that thing!)

@tbone321
Like  I say I looked at one right up close (like 6 inches away) because I needed to see what it was :) , definitely not LCD.. they were tiny RGB LEDs spaced around 1/4" apart (I had meant to take a closeup pic, but forgot)

@chrisatpsu
The brown was made with a combination of red/green/blue

If it's producing brown, then it's using a special controller that's capable of adjusting HSL, as well as RGB.

To the best of my understanding typical RGB christmas lights stuff, cannot get a brown out of the RGB LEDS, since they only adjust for RGB levels.

As you said, RGB Christmas stuff can't produce brown because there is no black.  Without black, you cannot control HSL.  These panels must be composed of clear lensed LED's on a black background.  Our nodes are white or clear lensed LED's on a white or tan board and where there is no black, there is no brown.

I have a feeling that whatever they were using works more like a screen/display type setup, than just a controller & RGB LED matrix.

Yep they were just that. clear LEDs, black panel.

I would have loved to see "behind the scenes" - the system(s) that were running it.
