This is an interesting idea! I'm not a digital signage expert, but I have done some projects with [1] and for 160mm (~6 inches) of panel you’ll draw up to 2 watts! Most digital signs I’ve seen in the wild appear to be composed of similar panels, and I’ve often marveled at how much energy they must draw (not to mention cost).

Huh? Missing Link? I always thought that digital signage displays were essential TV screens optimised for always-on, maybe with an integrated (network) media player. At least that's the case for an old LG digital signage display I happen to have upstairs (got it essentially for free due to aged backlight, was used in a pharmacy). But maybe that's just outdated info on my end ;)

  Sorry, link is here: https://www.digikey.com/en/products/detail/adafruit-industries-llc/3649/8535238?s=N4IgjCBcoLQBxVAYygMwIYBsDOBTANCAPZQDa4ArAEwIC6AvvYVWSAMwBsALAJwgNA https://www.digikey.com/en/products/detail/adafruit-industri... A lot of the bigger outdoor or more distant indoor signs I’ve seen in my neck of the woods appear to basically just be a matrix of surface mount LEDs w/ a pitch juuust small enough that from a modest distance it appears to be a full picture. The LG you have is essentially the same thing obv, but if you’re mounting a sign to a building or billboard you don’t really need that pixel density and the hardware necessary to drive them.

    I know the LED matrix displays you linked mostly from Festivals and from a few (3-5 I'm aware of) largish (<= 4m wide, I suspect) outdoor signs in our city. (Edit) Surprised they're more common around your place. But might just depend on region. I misunderstood that you thought mine was a LED matrix as well, but that was just my sleepy mind I think ;) still leaving the original comment below. (End edit) But there are also these: https://www.toshibatec.ch/assets/Uploads/Digital-Signage-Inform-RZ.jpg https://www.toshibatec.ch/assets/Uploads/Digital-Signage-Inf... And a bit simpler https://www.digitalsignage.de/files/digitalsignage/content/slider3/slider-digital-signage-im-handel.jpg https://www.digitalsignage.de/files/digitalsignage/content/s... They are much more common around here (200k pop city) than LED matrix displays, and often seem to run 24/7. These are essentially rugged, super bright, high-res TVs plus some PC to drive them. Maybe for larger cities with ad-heavy squares (think Time Square) these are significant consumers, but for our city I expect TV-like displays too consume more power (combined, not per-display obviously ;-)). But I suppose that bill targets both/all types anyway :)
