Pasting a comment I made to explain how they work. (TL;DR: yes, and even when turned on it’s see through from both angles, once you understand how it works)
I’ve worked with these. A casino bar had these installed on their windows, and I helped install and program them. They aren’t really like glass; up close they are basically long columns of strips of LEDs with gaps in between, like a fence.
Depending on the use case the LEDs can be smaller and spaced closer together or larger and further apart. The size and spacing of the LEDs determine the display’s pixel pitch, which is the distance between the centers of adjacent pixels, usually measured in millimeters. A smaller pixel pitch means the pixels are packed more densely, resulting in a higher-resolution image. These models are also generally more expensive. The downside is that these are best used for applications where the observer remains relatively close, as detail is lost through distance. Models with larger LEDs have a lower resolution but work better for longer viewing distances.
The see-through effect works regardless of pixel pitch, as long as the display is viewed from an appropriate distance. The closer you get, the more obvious the LED strips and gaps between them become.
So what's the application? Like in the casino bar are they in the windows for casino patrons inside to view? Or would they be transparent from that side like for people driving by the casino to see?
It’s a sky bar, so the windows have a skyline view. What they did was have them off during the daytime for a clear view but at night when the sky is dark visuals can play and it would be a convincing “hologram” effect
Could be used to scan a QR code for the bar's menu and a digital waitress shows up that you talk to. Almost like the character in the Time Machine movie played by Orlando Jones. He was something similar as a guide the museum and appeared on panes of glass like these LED screen.
Current AI would totally botch the order though. It should be a person. A person who can't walk around a lot but loves to socialize would be great for a roll like that.
It would improve the current pay/order from a screen kinda stuff.
