Ask HN: Why cant someone invent a screen with a webcam hidden in the center?

AFAIK Apple has patented that already.

It looks like it quickly switches off the display, takes a photo, and then turns the display back on.

A much easier idea would be to use something like a teleprompter. That way the camera is looking through the glass, but the image you want to see is reflected up on the screen. Not high fidelity, but it works.

I've thought about this. Unless a sort of one-way glass LCD screen is invented I don't really see how it's possible.

I always thought you could put four cameras, one on each corner, and then merge the images.

Or easier, just identify the eyes and adjust the position of the pupils on-the-go. Shouldn't be too hard.
