3-DHere's an excerpt from an intriguing post over at Engadget:
While we were fretting about what special tech Nintendo's 3DS would use to generate autostereoscopic imagery on its comparatively puny screen, Toshiba Mobile Display (and others) have been working on bringing that same headgear-free 3D to TV-sized panels. Employing a "multi-parallax" technique...the 9-parallax implementation requires the generation of 9 separate images and therefore could be achieved with only an "ultra-high definition LCD module. How large is the display being touted in this post? 21 inches. It was just a few weeks ago that this kind of technology was being described as unusable on larger screens and only suited for smaller mobile devices. That seems to have suddenly changed, and even with the generation of 9 separate images, the specifications include 1280x800 resolution and 480 nits of brightness, which are both quite impressive.
Now I'm wondering if the supposed limitations of the parallax method is due to the technology itself, or the cost. Previously, it seemed to be a technical limitation, but if a 21" display can use this technique, maybe larger displays can as well. Eventually.
