Hitachi unveils 4.5-inch 3D display with 720p resolution; no glasses required
Well, Hitachi has just unveiled an IPS LCD display that appears to be capable of bringing the glasses-free 3D experience to the next level. The panel may be only 4.5 inches in diagonal, but packs the impressive resolution of 1280 by 720 pixels, which is a step up from what one would see on a contemporary 3D-enabled device. Besides that, a quick calculation shows that the display clocks in at 326 ppi, which means that it should be able to deliver images as sharp and detailed as they look on the iPhone 4's Retina display, at least in 2D mode.
brighter in 3D mode than it is when displaying 2D images. That is accomplished thanks to the more efficient lenticular lens technology, which has been used instead of the parallax barrier method in creating the stereoscopic 3D effect.
It has not been said when Hitachi's display will become available or will it ever make it to a commercial device at all. However, that probably depends on whether there will be sufficient demand for the technology, and our poll from not long ago indicates that the market is simply not that crazy about 3D-capable smartphones just yet.

Watch out, Hitachi. That's groundbreaking technology. Apple is gonna sue.
Just kidding. Sounds awesome, though I have to say, the 3D existing now, such as on the Nintendo 3Ds. , looks pretty poor, to my eyes. It's almost distracting.

Evolution of glass-free 3D displays, good news! :)
Also there is some more interesting info about glass-free 3D:

There is serious problem with the HITACHI 3D screen design - have You remember that You might turn Your mobile phone in Portrait or Landscape mode? Well problem with Lencucular lenses is that once You bind them into the screen You could not rotate the phone in Portrait or Landscape mode - it will work only in one of those by the way how lenses was put (usually in landscape mode). Other idiotical thing is that You may not switch to 2D mode - all the time Your screen will be in 3D - where Nintendo parallax barrier can be turned off and You might Use Your device in 2D. So...Nothing special about Hitachi stupid Display. You say they do not want to make it Commercial yet -- Well now You know why. Their solution is nothing more than experiment and Air under presure - since they did not bring anything new. Where Nintendo really did bring completly new technology.
