The trick to any good 3-D tech is creating a system in which the viewer's eyes receive two slightly different images, creating the kind of dual perspective that gives imagery depth--and hence the illusion of three-dimensions even within a flat space like a television display. With most light emitters, which look the same when viewed from any angle, this can prove difficult. But a new kind of fiber developed at MIT that can emit light variably in different directions along its entire length can present light at different intensities to two different viewers, and it could lead to woven 3-D displays that project different visual information to a viewer's left and right eyes.
The fiber has a hollow core surrounded by layers of materials with various optical properties. That hollow core contains a droplet of liquid that can be moved up and down the fiber, and when "pumped" with a laser this droplet emits light. That light bounces around in those layers of optical materials, emitting a 360-degree laser beam.
But that emitted beam itself is also manipulable. Surrounding the hollow core are channels filled with liquid crystals, each of which can alter the emitted light. That means the fiber can emit light of one brightness in one direction, and light of a completely different brightness in another direction.
Currently the number of liquid crystal channels in the fiber numbers only four, but the researchers say they can build as many of these light-manipulating channels as they want around the central core, making for extremely nuanced control of the light being emitted in different directions. All that, and the fiber still remains around 400 micrometers across, or a few times larger than a human hair.
In experiments, the researchers are investigating whether or not they can create a single thin, transparent display that projects identical images to viewers on opposite sides (rather than the mirror images normally projected light would produce--imagine the view from different sides of a suspended sheet upon which an image is projected). But the grander idea suggests that displays woven from the fiber could manipulate the light so carefully that a single person's two eyes receive slightly different visual data, and thus create 3-D depth without glasses.
The researchers also see potential in the field of photodynamic therapy, when carefully directed light from a device injected into the human body activates optically sensitive therapeutic compounds, allowing for highly targeted internal therapies.
Stereoscopic is not 3D. Close one eye and then move your head and look at any object. You can still see it in glorious 3d. Without parallax it's not 3d.
Parallax is a perpetually more powerful indicator of 3 dimensions than stereo vision.
hopefully this will lead to computers with the screens as thin as paper but are super strong and are touch screen

I had the idea a few years back that you could build a display screen of woven fibers such that at any 'point' on the screen you could control its brightness and color, by choosing to send light down the two intersecting x-y-plane fibers that have a wavelength such that the light ONLY constructively superimposes (from a lightwave perspective) at the location where you want to 'turn on' a pixel. Or basically cause a point of light to occurr. Since wavelength of this light is used to modulate 'location' on the screen you would need three layers of the fabric, possibly interwoven, into one layer however, that are red-coated, green-coated, and blue-coated, because all you are controlling is brightness (via wave amplitude).
I guess this is not possible because this idea MUST have been already pondered by MIT since in my mind it is an 'obvious design' based on what they are now doing.
