Tungsten glass? The one that goes white when electricity passes through it? Opaque when locked?
thankfully it's usually the other way around: the glass is opaque and only transparent with power. So you don't need to worry about an ill-timed power outage.
That's called PDLC film (polymer-dispersed liquid crystal) and it's a thin layer you can apply to anything. It's literally liquid crystal droplets suspended in a plastic sheet layered between transparent ITO conductors (indium-tin-oxide).
A distinctive feature of panels layered with this is that there must be a bezel along at least one edge through which to run the power. I don't see any in the right places on the doors for these, so nope, these are just clear glass without any PDLC film.
Sure that's one type, but there are others too. Like electrochromic smart glass
Maybe they are yet to be decirated with "normal" film instead.
They have (had?) those in Tokyo for a while.
