Oh yes, of course, the transparent OLED
PART of this cannot "emit" a black, I don't think anyone's saying that. Or at least I hope not. However, a transparent computer monitor could certainly have an "opacity layer" (as Apple puts it) and have the transparency driven by an alpha channel. Something called an OLED TV (proper name for it) could well have that ability as well, but transparency for viewing content like movies, etc.? That'd be useless, ludicrous and above all annoying as hell. But to have it for a transparent monitor (like a phone or nifty tablet), I could see it.
I saw this conversation stemming from this comment from sytech

...and I was talking about how transparent OLED displays could have black accomplished by such an LCD layer behind them, because you questioned how.

You mean as black as Apple thinks? Sure, ok. Beats me. You'll have to ask them. How black would it be? You have me wondering that point---Wouldn't it be at least as black as a locally dimmed LED-LCD black is now? A background room light isn't the blasting LED bulb of LCD sets. The opacity layer wouldn't have to block out as much as the LED-LCD's currently do. But again, this idea isn't (or shouldn't be) for TV content.

and therefore won't be anywhere near as contrasty as a true OLED TV (b) not actually transparent, even though it's somewhat close to that. You could make a "transparent" TV this way, but it won't have "million to one" contrast nor be truly transparent.
It does not compensate for anything.
I don't see any reason for a transparent TV to begin with. Broadcast/Movie content that's hard to see? It'd have multiple uses in the computer monitor world, maybe for things like car windshields or places where people need to see around the computer, but for the tv-show and movie content itself? Unless it has double duty as a computer monitor where it matters to see through it, I can't imagine a world where that makes sense.
