this is a fascinating article as it goes into heavy detail about both techs and how they work.

but this did make me facepalm a bit:

"That’s why the transparent OLED TV LG demonstrated at CES 2024 included a “contrast layer”—basically, a black cloth—that unrolls and covers the back of the display on demand."

I'm not sure I can think of many practical applications for these devices.

Even using them for movie see through screens instead of CGI to save money probably wouldn't work due to not enough contrast under bright studio lights. They tend to CGI phone screens now.

The one theing they would be great for would be some kind of HUD style thing for whatever is behind the screen, but that would either be a vague info bit off to the sides or it would need to track the location of the person's eyes and what they were looking at for anything more precise. At that point it would be better as glasses/goggles.

the HUD is what i initially thought, but in that scenario they'd need the screen to be a decent window as well.

but yeah as you said it would have to be functional as both. and I don't see that happening.

i do wonder how often a technology is developed with vigor only to not sell well. i kinda see that happening in the future with this. which sucks because these have been in development for years.

Remember 3D tvs? This is basically the same kind of 'screen but different' application that has limited uses and some inherent problems that may never be overcome in a way that makes them better than a simple flat screen.

There are tons of other inventions and innovations that hard work is put in to and don't pan out. Things not working out is just part of the process!
