For a long long time, science fiction movies have used transparent displays to seem more "futuristic." However, actual transparent displays have been underwhelming in practice.

This technology is being use by Xaomi to make a "transparent TV"[1] which in theory you will be able to buy. (I realize that not all of these sorts of announcements survive until actual product shipment).

It will be interesting to see one of these "in the flesh" as it were, I'm at a loss what you'd have behind it that wouldn't make it really really annoying to watch, but the cool factor could be right up there.

It would be cool if they could be used to implement a wearable HUD-style/face mask interface, like Google Glass but where the entire lens is the screen.

Well, this would be another method for achieving heads up displays. Here's an application that I think would be really cool: HUD retrofits for cars. Take a transparent plastic film, stick it to the inside of your windshield in a similar manner like you would apply a tint film to the side and rear windows. Then, take the connector dangling from the corner of the film and connect it to the supplied box which connects to the ODB port, or some other standardized connector which connects it to the necessary vehicle systems.

I could also totally see Tesla or one of the older luxury car brands doing something similar, where the HUD in the front windows is integrated into the car systems.

IMO, the harder part will be not integrating the technology in this article (or something similar), but designing the HUD to be something actually useful and informative to the vehicle operator, affording them better, more informed control of their vehicle, instead of being some distracting thing that you can't disable.

Why not combine the two? Have your traditional opaque displays, then overlay the transparent system. I imagine this could be useful in court, allowing both the prosecution and defense to scribble on video evidence presented to the jury to point things out and highlight important bits, without ever modifying the underlying evidence video. Kinda similar to how sports commentators will use video overlay to scribble on replay segments to point out the movements of the various players to highlight why those movements were important and contributed to the outcome.

how do they do the black?

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.

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 the technical effort (in many ways that was fun) but just because how impractical they were in many scenarios.

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.
