There are reports that Amazon is working on several Android smartphones. One of these "Kindle Phones" will sport a glasses-free 3D display. Reportedly it will use eye tracking to enable hologram like visuals.
If everything works according to plan, the first such Kindle Phone (maybe not the 3D one) will be announced soon, within the coming months. This is just a rumor currently, but an interesting one...
UK 3D solutions company, Stereoscape is going to launch Dimenco's 50" 4K (3840 x 2160) glasses-free displays in the UK on April 16. Stereoscape will aim towards visual communications and experiential marketing applications.
HP Labs researchers developed a prototype glasses-free holographic LCD display. As a holographic display, there's no limit on viewpoints. The display uses so-called directional pixels that are made up from nanopatterned grooves on the display that send light off in different directions. Each pixel has three groove sets - to direct red, green and blue light in different directions. The reflected light passes through a regular LCD panel that handles image creation.
This is still an early stage prototype, but still an impressive achievement. The prototype can show static images in 3D from up to a meter away in 180 degree field of view. 30 fps video is only viewable in 90 degrees. Creating the content is not easy - a single 3D image requires taking 200 different images.
Sterrix announced today that the European Patent Office (EPO) granted the core patent of their Pseudo-Holographic display technology. Sterrix says that their technology is an extension of autostereoscopic (glasses-free) multi-viewer display technology. PseudoHolography allows generating an infinite number of perspectives and optimal viewing positions in real time.
The technology uses anatomy adaptation to the human eye, stereo base extension, a new pixel structure and 100-times greater then HD resolution. According to Sterrix, PseudoHolography has the following benefits, for every viewer:
Panasonic developed a new CMOS sensor (2.1MP) that can take 3D videos with a single lens. Panasonic's CMOS uses lenticular lens and mirror elements (digital micro lenses, DMLs) smaller than light wave length (using lithography technology). The lenticular lens separate the light and the mirrors increase the light intensity. The CMOS includes pixels for the left and right eyes. With this sensor it's possible to take 3D videos of objects that are about 1 meter away from the lens.
Panasonic aims to commercialize products with this new sensor in 2014, for both the industrial market and the consumer one (mobile devices).
