Thanks for commenting.
I don't think the line that make up the hexagons are traces. Look at the terminals and you can't see traces (and there must be some) and the hexagons don't join up with the terminals.
...
Sure that's possible. Seems like you'd only need some unique alignment symbols at the edges but the larger pattern looks good too. But if you try to avoid the "hex pattern" lines and just look at the LED placement, it still seems strange. If I did it, I would put a line of LEDs across. Then the next line would be spaced below with the LEDs halfway between the ones in the first row. Lather, rinse, repeat. Maybe the spacing they used resulted from the designer's research on how the backlighting best looks.
I did notice that the center two rows of panels going across are wired together with bus bars, but above and below them those panels are not connected to them. They seem to have a larger space between the panels. Perhaps those sets need another power supply?
The panels have a manufacturer name and details printed on them. Can you go back and take a closeup of that?
Or just zoom that part of your image if it can be read.
I tried to "sharpen" the text but the results didn't look good. I can try another program, or (since I go there three times a week) take another close-up of the printing.
I'd like to buy some of those panels from that window. I did know a person in the mall office several years ago, and she allowed me to buy a small utility tray table and a small LED desk light from a long abandoned nail spa - I think I paid $5 for both of them. I don't know anyone in the mall office now, but it can't hurt to ask I suppose. It's a shame that these nice panels are going to go unused for as long as it takes for the poor mall to either re-organize itself into something useful ... or be torn down. From the way things are going, being torn down looks to be the best option.
