What sort of 3D displays do you mean?
Like, holographic technology? I was looking at holographic technology
on the net so it's already been made but it still needs to be
developed and refined and stuff until it can enter the mainstream
market. So probably there is a long way to go.

Right now the coolest thing out is OLED, organic light emitting diode.
Have you heard of that? It's so thin! I want to buy a TV built with
that but they are really expensive. Totally next gen though! Imagine
just sticking it to the wall like you would with any poster or
painting. Except... it moves! Kind of like the pictures in Harry
Potter.

Imagine using a laptop without having to wear corrective
eyeglasses.

I know that 3D displays exist that don't require special glasses.

So maybe this is possible as well?
