Mashable reports that the 3D titles will be available at 480p, 720p and 1080p resolutions, with the minimum bandwidth requirements for 3-D viewing being the same as for 2-D. To be able to watch the 3-D content you’ll need a compatible HDTV/Blu-ray player, which includes Sony’s PlayStation 3 as well as devices from manufacturers such as Funai, LG, Mitsubishi, Philips, Samsung, Toshiba and Vizio.
This and the fact that there's no mention of HDMI 1.4a leads us to believe this here 3D is of the frame compatible variety -- not that there's anything wrong with that.
Autostereoscopy is a method of displaying three-dimensional images that can be viewed without the use of special headgear or glasses on the part of the user. These methods produce depth perception in the viewer even though the image is produced by a flat device.
Several technologies exist for autostereoscopic 3D displays. Currently most of such flat-panel solutions are using lenticular lenses or parallax barrier. If the viewer positions their head in certain viewing positions, they will perceive a different image with each eye, giving a stereo image. Consequently, eye strain and headaches are usual side effects of long viewing exposure to autostereoscopic displays that use lenticular lens or parallax barriers.
These displays can have multiple viewing zones allowing multiple users to view the image at the same time. Other displays use eye tracking systems to automatically adjust the two displayed images to follow the viewer's eyes as they move their head.
A wide range of organisations have developed autostereoscopic 3D displays, ranging from experimental displays in university departments to commercially available displays. Examples include: Alioscopy, Apple, Dimension Technologies, Fraunhofer HHI, Holografika, i-Art, NewSight, Philips (see WOW VX), SeeFront, SeeReal Technologies, Spatial View, and Tridelity. Sharp also claim to have the technology, although not for commercial sale at the moment.
