HDTV Almanac - Toshiba Shows No-Glasses 3D

[alfredpoor]

Here’s the good news: at CEATAC in Tokyo this week, Toshiba demonstrated its flat panel HDTVs that create 3D images without the need for any special glasses. The technical term is autostereoscopic, and it’s just what consumers have been clamoring for. And the demonstration now proves what I’ve been saying all along; consumers are going [...]

We need choice #4. A 3D projector.

Unfortunately, a projector does not change the choices. You're still stuck with either active or passive glasses (I don't know of any autostereoscopic projection technologies). There are plenty of 3D projectors on the market or on the way. As with flat panels, it's a relatively simple matter to add time-multiplexed stereoscopic images with active shutters.

Yup, that's exactly what we need, either as a projector or a flat screen. One of the problems with holograms, however, is that they need more than two views for most implementations, which greatly increases the bandwidth requirements for the image signal (not to mention production costs).

We're a long, long way from "Help me, Obi-wan."
