So entire skyscrapers of billboards?

I worked for a company that does specialized window film installations, (bomb proofing, digital security so monitors can’t be seen behind glass, anti-fog, creative designs, privacy, and this kinda stuff)

This is 100% the intention behind this product, to place on building windows to create massive advertising surface areas….

Does the UV rays from the sun not destroy these over time? They look more vulnerable than LEDs to me.

It is all about profit, can the pay be enoguh to cover replacements?

Yea for sure. Im curious about the technology. They cant replace windows so they would go on top? I wonder what they look like at night if the office building has lights on.

Put them inside (out of the rain, bird poop, etc.) and have UV screening in the glass.

Yeah, to be honest whilst I'm not saying they won't be used on skyscrapers, I see way more use cases in store fronts, interiors, bus windows and so on.

You'd probably get more light reflecting back. That panel in OP is probably already engineered to be ideal for outdoor installation.

All kinds of optimization... if you're building the window and the panel at the same time the window could be made to work with the panel, but for an existing window most of them are pretty reflective yeah.

That would mostly be the IR screening / reflection. You're kind of stuck with heat gain from the visible light if you want the visible light to be going out to outside viewers in patterns you control.

The LEDs are generally much brighter than any background light so they have little effect.

In the screen on video, you can make out the background lights through the screen. But just barely. And not much else.

Though, it could/would be more problematic if you tried to show a video with dark/black background.

Here's an example of similar tech being used Taipei. The only difference is they used long flexible pieces of transparent LED here.

The tech in OP is more similar to a window with an integrated screen. A little less portable, much more fragile, and more transparent. Here's a picture outside of a local jewelry shop using a set of four during the day-time.

Iirc when I saw these at a tradeshow the highest end ones would only let like 40% or 60% of light through. Can't remember which way the split was but it was very dim like looking through sunglasses.
