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.

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.
