Glasses-free 3D

The Setred MD20-3D 20" Display (together with the Samurai 3D Medical Imaging Software) enables surgeons, radiologists and other medical professionals to view more patient images at one time than ever before, in 3D and without the use of glasses.

The SETRED MD20-3D display and Samurai medical imaging software is now being launched commercially after successful testing in Sweden and Norway.

SeeFront is showing their glasses-free 3D display technology prototype. They are using special optics mounted on an LCD display, and combined with a tracking camera and their own software, this can be used to create a 3D effect. They say they can turn any display into a 3D one, from mobile phones to monitors. In their technology, there is one user that is being 'tracked' by the camera, and this person can move around freely. Others can view the 3D, but they 'depend' on the position of the "master" viewer.

The Fraunhofer Institute is showing a new 3D display solution that does not require glasses. The idea is to use eye-tracking, and so there is no need for 'multi-view', and the user can move around and still get the 3D display. The analog display uses mechanics to adjust the images to the viewing angle. I'm guessing that currently this supports just one user, and probably is more suited for business-use and not multi-user TV...

TI showed a new 3D display for mobile phones, running on an OMP3 chipset. The display is a 120Hz LCD with an 3M film that direct the images to the left or right eye alternately (3M has unveiled this technology back in November 2009). There's no need for glasses - although movies do not look so good (still images are said to be great). 

TI also said that the new OMAP4 chips will enable HD 3D movies (dual 720p) and output them via HDMI. Phones that will have two cameras will be able to record 3D images.

MIT researchers from the SENSEable City Lab have created a new volumetric 3D display that moves around - using a "swarm" of micro helicopters, each functioning as a single pixel...

It's not clear whether the display actually works yet... but what a cool idea!

PureDepth announced today that they have acquired a patent for Multi-Layer 3D OLED displays. PureDepth Multi-Layer-Displays (MLD) use two or more displays that are placed one in front of the other to create 3D effects. These 3D displays do not require glasses and provide real depth.

One of the markets the PureDepth are targeting are mobile devices, and OLEDs are becoming more and more popular in that market. Up until now PureDepth had only LCD related patents, but now they can work on 3D OLEDs, too.

Sunny Ocean Studios from Singapore will unveil a new 27" 64 viewing-angles no-glasses 3D display (autosterescopic). Sunny Ocean also say they can refit normal displays into 3D ones. In fact, they say they can do so for displays up to 100" in size.

More information will be given at CeBit (March 2nd). Via Engadget.
