Fundamentally, this is new technology which won't be prevailant for years. By the time it happens, CRTs will be dead and buried. TFT screens are getting so good/cheap that the CRT will become obsolete over the next couple of years. The colour reproduction in some TFT screens [eizo.co.jp] is pretty much as good as CRTs and the resolution of others is way higher than that of a CRT. Combine the two with a good viewing angle and you'll never want a CRT ever again...

The problem with the Sanyo display was that, a) it had a very small "sweet-spot" in which you could actually view the stereo image; b) the technque of using a "paralax barrier" means that you halve the vertical resolution as each alternate column goes to only one eye; and c) you get slight visual artifacts as a combination of both of the first two points. Oh, and it is definately not cheap.
Actually.. Sharp's press release is a fairly accurate description of the system Sony was producing back in '99. Good luck to them!

Sharp were also the first to produce 16" TFTs (one of which I own) which while double the price of the cheapest 15" displays, have a response rate of *half* what normal TFTs have, sRGB profiling, dual inputs (VGA/DVI), and a 1280x1024 resolution.. compared to the awful 1024 of most smaller TFTs. The 18" Sharp TFTs are pretty much the same, but larger, and oh so sweet. The 16" TFT is 104dpi. With ClearType, that leads to 300dpi (horizontal) goodness on text.
Another thing Sharp has pioneered is 'slim bezel'. Most Sharp TFTs have a bezel of about 1cm, compared to the horrid 3cm+ bezels of most TFTs.
Sharp are the kings of TFT (except, perhaps, IBM who produces those 300dpi dowickeys), and anything they produce has got to be hot.

Objects are perceived as the same distance away when light takes the same amount of time to traverse from each of the objects. Therefore you can imagine the world as a series of concentric spheres about your eyes, each sphere representing a "plane" of distance. In order to create the illusion of 3d on a 2d surface, it is required that the light traversal time be increased for those parts of the scene that are to be perceived as "deep". The problem is, while there are ways to make light go slower, the thickness of a sheet of paper (or even a computer monitor) isn't enough space in which to do it.
Therefore, until some fundamental hurdles are overcome, 3d computing is only a pipedream.

BZZT! Wrong. While the brain is a fantastic piece of biology, variation in lightspeed from objects that surrounds you in a room or outside are way too small for you to register.
The brain calculates differences in angles from our two eyes to find out how far away an object is, as well as references to other objects for far away objects.
Stare at an object and open and close your right then left eye. You will notice that objects shift from left to right as you do this. Objects closer to your eyes shifts relatively more than objects further away. For objects further away, a linear approched is also used, as in object B is behind A, therefore B is further away.

anyway, what you've described (parallax) isn't our only sense of depth perception, but it's the easiest to recreate with a computer. the _other_ way we sense depth is a hell of a lot harder to recreate digitally - focus. we have to change the geometry of the lens in our eye to change focus from something that's near to something that's far. parallax displays will create a credible sense of depth, but it's still not entirely believable as both eyes are seeing the entire scene on one fixed-distance planes.

One thing that will make or break this technology is how precise your head position has to be. It would seem to me that only an inch or so would put your left eye where your right should be. Not many folks are used to having to hold their heads that still while using a computer.

I can only guess that you must have been a little kid to have missed out on Virtual Reality. Really, what is today Q3A and UT grew out of the want for better 3D graphics for those systems (I am not saying VR begat Quake, but it did influence the development of 3D engines, etc). HMD's, head tracking, glove input devices, 3/6DOF position sensors, etc.
I have a wierd feeling - I mean, back then (and less so now, but still happenning) a lot of people were developing VR systems AT HOME - using 386/486 machines, Amigas, LCD TVs (for HMDs), potentiometers and wooden arms (for head tracking) and Powergloves to interact with 3D worlds they created (most of the time using Rend386 or other homebrew 3D software).
What has happened? Has all of this knowledge, not to mention the knowledge of the existence of this knowledge, been lost? Heck, I KNOW that can't be the case, my website has a ton of the old stuff on it - I still see new stuff appearing now and then (such as that Linux PowerGlove driver that works great with my modded PG). It seems crazy - but it is almost like you are one of a growing cadre of people who are TOTALLY unaware of this technology - and furthermore of the fact that today one can build a homebrew VR rig ULTRA-CHEAP, given some time, materials, and a little knowledge. Even if everything was bought off-the-shelf, it still would cost less than $5000.00 to do it. Buying used, or building, that cost could easily drop to below $1000.00.
I am wondering if VR isn't undergoing something like the concept of a windowing desktop - I mean, the first such desktop didn't come about until 1969 (or was it 68?), but it took another 15-20 years before it really started to catch on, and another 10 still before it became ubiquitous - perhaps around, oh, say 2015 to 2030 I should expect VR to hit BIG, and it will be NEW and FLASHY!

Say you want a low frame rate of 60 total updates per second, and you want an effective resolution of 50dpi (very low resolution, very slow update) and let's make it easier by using only 8bpp coloring, in a 10"x10"x10" cube - again for simplicity.
500x500x500pixels = 125 million pixels, or roughly 120MB of data per screen update. Multiply by 60 updates per second and viola! About 7.2GB per second of data. Current video cards (even high end) can't even handle this low resolution, slow, low color display. And the scale is exponential n^3. Your video card barely has 128MB of memory.
A 15" display, 100dpi, 75Hz update and 32bpp is going to consume just short of one terrabyte of information per second.
Eventually the display will contain the 3d processing hardware and its own memory, and the computer will send it directx 12 commands (or opengl, or cg, or whatever).
But for situations where the data only needs to be viewed by a single user, these displays are wicked overkill. You've only got two eyeballs, take the 200dpi displays from IBM, sony's technique, and you've got a significantly better image at lower cost.

It was created by Kenji Tanaka, et al at Tachi Lab, University of Tokyo [u-tokyo.ac.jp]. I would imagine such a device could even be built to do full 3D, perhaps by using shutter glasses of some sort synched to the scanning of the LEDs. What would also be cool is to add a head tracker that could tell which direction you are looking in, and only activate an "arc" of panels such that the view went beyond your peripheral vision, but didn't wrap around, lessening the load on the computer driving the system (why display what you can't see?)...
