One of the other 3D oriented threads has had quite a discussion of so-called "Glassless 3D Displays". The point was brought up that this topic deserves a thread of it's own. So here it is.
Here is one of the links from that thread (thanks Lee) that lists a lot of the "players" in this area.
An emerging technology that is going to takes years to perfect.
There are so many different issues associated with Auto 3D:
1. Resolution of the images you see. Today - what was shown at CES 2010 - a bit better than DVD resolution.
2. Being able to watch either 2D or 3D like todays 3DTVs will allow.
3. The number of views needed so that moving your head will not collapse the 3D affect. Most are in the 9 view range (Stereoscopic 3D has 2 views = L & R) - it isn't enough. This coming week, an Asian company will show a 27" Auto 3D display with 64 views at CeBit (Germany) which starts this coming week. I will post whatever they announce in this thread.

Philips' WOWvx allows 2D and 3D viewing on a single display. By detecting the content type, a soft switch makes a seamless transition between the two viewing modes. In 3D mode, each lens in the display bends the light in several directions, generating a 3D image. For displaying 2D content the lens effect can be eliminated by...
I was very interested in seeing glasses free 3D at CES. I was sorely disappointed at the results. If you click the link above, one of the manufacturers says it will be used for "signage." In other words, the picture is really sucky, but the effect is just good enough to where you could put a display in a mall and it would get people's attention. The screen is divided into sections using a lenticular lens. The content on the screen is multiple versions of the same subject shot at slightly different angles. Because the subject is repeated, the picture is low rez and if you're not lined up exactly with one of the angles, a blurry mess. However, when you are lined up, it looks OK, and when you walk by it or change you're point of view, the video changes with you--also impressive. Again, it will be just good enough to get peoples' attention for advertising, but nowhere near the way you would want to watch a movie. And of course the big caveat is that it's not compatible with today's HD video standard. I'm convinced that it will be many years before we see glasses free 3D in the home. The above approach could work perhaps if you could start with a 4K resolution picture before dividing up the screen. We all want 3D holographic displays that you could actually walk around someday as well, but again, these technologies are totally incompatible with what we have now.

It can be converted to the format they use - ie. they can convert 2D to their format or stereoscopic to their format (not necessarily in very good quality but at least it can) or much better - any 3D CGI film if they have access to all the original full 3d (not just stereoscopic) data.
I am posting this link here because although the TV in question was just a protoype and Philips has stopped their R & D on Auto 3D, it does show what could come out in 7 to 10 years (just guessing)
Philips’ 3D HDTV Might Destroy Space-Time Continuum, Wallets
I produce photographic quality autostereoscopic prints and that requires about 1,000 vertical lines of resolution PER INCH along with twelve 21 megapixel high end cameras to produce the content. Video monitors are going to need at least four times their current resolution to be in the ball park of quality. Of course this only provides for left/right 3D and no vertical information. The cool tech coming is microdot lens material used in conjunction with plenoptic cameras with millions of lenses. This has great potential but perhaps 10 years off. In the meantime, I think shutter glasses or polarized passive glasses are going to dominate and the autosterescopic monitors won't get much traction because they aren't good enough.

Do a search and find my blog where I go into a lot of detail about 3D multiperspective photography. There is a lot involved in making it work. The display tech is actually the easy part ;^)

Tokyo - Nintendo announced here this week that it has developed version of its popular DS handheld game player that supports 3D without the need for special glasses.
The Nintendo 3DS will use two screens and will be backward compatible with current DS and DSi games, the company said here Tuesday.
In a way it is going to be misleading to people because the DS tech will rely on the user being basically stationary in space in relation to the screen. People will see that and say "why can't they make a big TV out of this technology so we don't need glasses?" but of course it doesn't work for multiple viewers at different angles.
This whole 3D arena is going to be hard to educate the general public on why it can't be done with their existing TVs because when they go to the movies it just looks like a big TV with a blurry picture and they put on some funny sunglasses and voila, you've got 3D!

Seems like it'll be years and years off. But still, Id be surprised if someone doesnt try to come out with a mainstream solution within a couple years.

Yes I know, I was talking about the possibility of a an autostereocopic display incorporating processes that convert 2D to 3D, different 3D formats etc.
You lost me - this is a thread on Auto 3D. Why show the Toshiba Cell TV? It isn't an Auto 3D display

LOL - let's see one do 3D properly first. BTW - all the Auto 3D displays are based on 2D to 3D conversion. They all need a PC attached to them to create the multiple views using special software sold by the Auto 3D display manufacturer.
I was pointing out the automatic 2d>3d conversion process and whether something like it could be possible with an auto 3d display(in realtime)

Not that difficult. Much harder to get the resolution up to where S3D is today, then it is to do 2D to 3D on the fly. Just need BIG buffers and LOTS of processing power.
