The article mentions using these displays, with a camera behind them for zoom calls.

Are these displays capable of only emitting light in one direction?

I would think that the light would bleed out both sides.

Also, there are plenty of existing teleprompter solutions using angled glass instead of a transparent led panel.



Maybe the screens only emit polarized light which can easily be filtered out?


But filtering out means it would look black to the camera, isn't it?


No, unless the reason it's emitting polarized light is that the "transparent" screen acts as a polarizing filter.
