Transparent OLED on subway video https://en.oledspace.com/a-closer-look-into-beijings-futuris...
Transparent screens could be useful in all sorts of scenarios, but I think tech demos too often ignore the fact that, most of the time, you want the image to be as clear as possible, which means opaque.
Henry Danger, a show on nickelodeon has featured transparent phones and tablets for years. Seems like they were right that this was the future: https://opera.news/ng/en/technology/6a64c11b10e73b1e7f76cd12... https://nickalive.blogspot.com/2015/11/sneak-peek-of-new-hen... http://nickalive.blogspot.com/2015/11/sneak-peek-of-new-henr...
I had an idea recently about creating slight-3D displays by stacking layer of LCD panels that give some impression of depth when moving your head, this might make that feasible.
You might find "tensor displays" interesting. https://web.media.mit.edu/~gordonw/TensorDisplays/

Sunglasses block much more than 30% though. And can have a mirrored surface so others can't see your eyes, or your creepy app notifications :)
Fair point re: sunglasses! Not sure "mirrored" would stop light being projected back through but may well help disguise it. Maybe a simple black LCD layer to block the outgoing light might help. Also, I don't want the creepy Xray app. But porn has this way of working into society/technology so I don't doubt for a second some form of that app will exist if it doesn't already.

The thought of a webcam constantly pointing at users has already creeped them out enough to make camera covers a popular item. Imagine how well that segment of the population would react to a hidden camera...
I think one solution would be like a purism laptop (and upcoming phone) - hardware switches (they one for camera/mic, one for bt/wifi)
Marketing: 'So, we can monitor users and collect sellable data through a camera hidden behind their monitor?'
Engineer: 'Why yes, but maybe we should allow users to disable this through some kind of hardware switch. It could lead to potential privacy violations etc.'
Marketing: 'If they turned it off could we still collect marketable data?'
Engineer: 'Well no...that's sort of the point...'
Marketing: 'I see...so invisible hidden cameras that can't be disabled you say?'

Yes, I worked on a video game that was in the near future and had transparent and semi-transparent screens everywhere. I spent a lot of time adding new rendering features to the engine that did proper transparency sorting, blur/darkening passes and helping artists tweak materials to make them more readable. At multiple points in the project I wanted the art direction to switch to opaque screens. Not only because of t…
Tangentially related, the "futuristic" displays in video games and movies and TV often look worse than what we'd see in real life. Sometimes it's a hologram, which would be cool even if the fidelity were a bit shit, but it's interesting that art directors make them pretty bad looking even in fiction, presumably as a cue to the viewer that it's a hologram. Any fiction that portrays holograms as opaque and convincing u…
Xiaomi just released their transparent OLED TV. It looks surreal: https://www.theverge.com/2020/8/11/21363861/xiaomi-oled-tv-t...
Would this be useful for augmented-reality headsets?
Assuming the transparency (article says 70-80%) can be improved for clarity and the pixels small enough then it could be great. However you'd have to keep in mind that others looking at your face could see the same image. So don't go running that "X-RAY:make them appear naked!" app...

My first thought was "well of course they don't," but their concept renders do indeed have opaque black. I'm guessing these are just technically uninformed renders with no basis in actually-proposed applications, but it seems at least plausible that one could combine transparent OLED with a transparent LCD backing (sort of the inversion of a backlight) to create a variable-transparency screen.
Pardon my ignorance but wouldn't LCD need polarized light to perform the darkening? Maybe a transparent pixelated electrochromic display layer might work
