It surely looks cool. But why would I want it?

If they can make them small enough and cheap enough, they could be used in simple AR glasses maybe.

Sort of. The problem is that I can't focus on something 2 inches from my eye, so there would need to be a lot of other optics involves.

I'd much prefer a TV that was transparent when switched off over the giant black rectangle of doom in my living room. I find myself switching it on to have the Apple TV screensaver instead, just because it's so imposing otherwise.

The black rectangle problem isn't talked about enough. Screensavers are something, but have their own problems. I'm surprised there aren't more mechanical solutions (e.g. roll-down shade).

So instead of a black rectangle, you just have a shade of whatever material in the same shape as the black rectangle? How is that an improvement.

I like the use of the screensaver as it is something closer to having art on the walls, only it is updating. Even if you had a large piece of art under the screen so it was visible when the TV was off would still be better than some roll-down shade.

> How is that an improvement.

True trading a black rectangle for a beige rectangle wouldn't be much of an improvement, but a piece of artwork would be.

Screensavers are nice, but emissive displays always stand out against other, reflective, decor.

Since they're attention grabbing, I fully expect to see them in casinos.

cars? displaying stuff on a transparent surface, it might be something useful.

I'm guessing ads

any time you need a window that can also display data

That’s gonna be an expensive window.

Or, the window can be free if you are OK with it displaying ads!
